ITEMS FROM STAFF: A. Receive and File Traffic Enforcement Updates for: 1. Citations: January, February and March 2015 2. Collisions: January, February and March 2015 3. Street Sweeping: January, February and March 2015 PWD/Liu stated that during the Commission's March meeting, VC/Mok asked about the street sweeping citation proceeds. According to the City's Finance Department, one hundred percent of the proceeds are directly deposited to the City's General Fund for discretionary use for public safety programs, road maintenance, and other services. During FY 2013-14, fines paid totaled about $222,000. For FY 2014-15, it is estimated that approximately $230,000 in fines will be collected. VC/Mok thanked staff for the response to his question. VC/Mok moved, C/Pechy seconded, to receive and file the Traffic Enforcement Update reports for January, February and March 2015. Motion carried by the following Roll Call vote: AYES: NOES: ABSENT: IV. OLD BUSINESS: V. VI. NEW BUSINESS: COMMISSIONERS COMMISSIONERS COMMISSIONERS None None STATUS OF PREVIOUS ACTION ITEMS VII. ITEMS FROM COMMISSIONERS: Pechy, Sulakhe, VC/Mok, Chair/Carrera None Mehta None C/Pechy stated that he noticed a number of business signs that are written in a foreign language only and wanted to know the City's position. PWD/Liu said his understanding is that foreign language signs are permitted; however, the City strongly encourages that businesses provide signage in English as well. He said he would follow up with the City's Planning Department and provide a more complete response at the next meeting. C/Sulakhe reported that today it was a very smooth drive for her from south to north Diamond Bar, which was not the case on Monday. She realized after the fact if she had gone onto Diamond Bar Buzz, she would have known not to travel the area. APRIL 9, 2015 PAGE 3 T&T COMMISSION Chair/Carrera asked if the flashing red lights at the intersection of Diamond Bar Boulevard and Maple Hill Road was a result of a power failure or construction on Diamond Bar Boulevard. AE/Beshay reported that it was a result of an Edison planned power outage. Chair/Carrera said he thought Edison chose the worst time because it was still flashing red about 5:00 p.m. AE/Beshay indicated the work was supposed to be finished earlier; however, the crew ran late due to unforeseen conditions in the field. VIII. INFORMATIONAL ITEMS: A. Edison Upgrades at Diamond Bar Boulevard and Grand Avenue — AE/Beshay reported that all electrical work has been completed. There is a small amount of restoration work to be done around the last vault on Diamond Bar Boulevard as well as removal of the underground service alert markings along Diamond Bar Boulevard. C/Pechy asked if after the work is completed, the City sends someone out to inspect the patch job that has been done on the street. AE/Beshay responded "yes." C/Pechy said that he was at Diamond Bar Boulevard and Grand Avenue today and he was not overly impressed with the work that was done by Edison and the contractor. SCE/Young explained that the City gave permission for Edison to leave all of the trench work within the Grand Avenue Beautification Project limits as base paving because the City will grind the entire intersection during the beautification project as well as each leg of the intersection up to the first driveway. Everything outside of the beautification project limit had to be final paved. C/Sulakhe asked if there was a checklist. SCE/Young replied that for all encroachment permit work by utility companies and private contractors, the Public Works Street Maintenance Superintendent is responsible for finalizing the permits and if there are any deficiencies and if the Superintendent is not happy with the paving, he will require that the issues be corrected to meet the quality of work expected by the City of Diamond Bar. AE/Beshay further explained that there is a punch list of items that is generated to address issues that must be corrected. B. Reagan/Peterson Park Parking Lot Construction Project — AE/Beshay reported that the project is still under design. Also, staff is in the process of obtaining a permit from L.A. County Flood Control to connect the proposed bio- filtration system into the L.A. County catch basin. The construction phase is scheduled to start at the end of June, after Father's Day. C/Pechy asked if the baseball fields at the end of Sunset Crossing Road were City -owned or private property. PWD/Liu responded that it is private property. APRIL 9. 2015 PAGE 4 T&T COMMISSION C. Morning Canyon Rehabilitation Project — AE/Mosley explained that this project is being redesigned. The redesign includes minimizing the roadway width by eight feet to widen the parkway to accommodate tree root growth. As a result, parking along the street would be impacted. The Community Services Department is reaching out to the condominium homeowner's association to receive input toward the project's design. With the elimination of street parking, staff wants to make sure the association is on board with the project. Staff is waiting to hear back from the association and hopes to have a meeting with the board members to discuss the design. Chair/Carrera asked how dependent the homeowners are on the street parking. AE/Mosley explained that part of the reason staff has reached out to the homeowners is to answer this and other questions and concerns. He said he does not believe that any condo complex would be happy about losing parking. Staff has explored alternative parking between the northern and southern portion of Morning Canyon Road to include both condo associations along the project limits. VC/Mok asked if staff had the dates of both association meetings. AE/Mosley reiterated that the Community Services Department is dealing with the property management group and to date, staff has not heard back from the property management group or been made aware of any dates that are available for presenting the design information and receiving feedback. C/Sulakhe was unclear if it had already been explained and asked if parking spaces were being lost. AE/Mosley restated that the proposed design would extend the parkway eight feet so that the curb face would be moved inward eight feet. This would result in a loss of street parking. D. Area 3 Road Maintenance Project — AE/Mosley conveyed that, as part of the City's seven year Roadway Maintenance Program, this year includes the Area 3 Roadway Maintenance Project. The project lies within the boundary bordered by Pathfinder Road to the southern portion of the City limits on both sides of Diamond Bar Boulevard, excluding The Country Estates. The project is out to bid with a bid opening scheduled for April 20th. The goal is to begin construction in early June and have the work completed prior to the beginning of the school year (mid-August). E. Comprehensive Groundwater Drainage Study — AE/Mosley explained that the purpose of the study is to develop a comprehensive plan to address groundwater and surface area drainage at several locations through the City. Recently, there was a contract amendment with Tait & Associates to include geotechnical services at an additional location for a total of 11 locations throughout the City. Once this area is included in the study, staff will review the findings and use the study to continue to address groundwater at each location. APRIL 9. 2015 PAGE 5 T&T COMMISSION F. Gas Company Upgrades at Golden Springs Drive and Grand Avenue — AE/Mosley stated that this project is on hold. The Gas Company asked to meet with staff to study the City's restoration requirements. No date has been set and since it is a Gas Company project, staff will wait for their contact. G. Grand Avenue Beautification Project - SCE/Young conveyed that the pre - construction meeting for this project is scheduled for the afternoon of Thursday, April 16th. Staff anticipates construction will begin in mid to late May and wanted to have the pre -construction meeting early enough to provide time to iron out details prior to the start date to avoid further postponements. Staff and the City's consultants met with Caltrans regarding construction oversight yesterday to review federal funding requirements that need to be met during construction. It is essential to ensure that the federal funding will not be jeopardized at any time during construction. The meeting was very productive and staff as well as the consultants are on board to move forward with construction. Chair/Carrera asked about the percentage of federal funding. SCE/Young responded that the City has just under $700,000 for SAFETEA-LU funds and just over $300,000 of STPL funds, which is about 50 percent funded via federal funds. H. Lemon Avenue Interchange Project — SCE/Young indicated that staff continues to work on revisions that were requested by Caltrans. The latest revisions are to encase two existing waterlines along Lemon Avenue. Walnut Valley Water District is working on processing a change order to their contracts so that this can be addressed to resolve most of the utility issues. Once complete, staff can submit the plans to the Office of the Engineer by the end of April. Willow Heights Construction Update — SCE/Young reported that progress is being made toward the Grand Opening, which is scheduled for Saturday, April 18th. Staff anticipates that the developer, Lennar, will have their Certificates of Occupancy for the model homes. There are three products in the community including the Viridian product, a single family home; the Sage product, which is a detached cluster home; and, the Olive Crest, which is attached condominiums. The Grand Opening will take place from 10:00 a.m. to 6:00 p.m. All parking will be at Diamond Bar High School and shuttle service will be provided by Lennar to and from the parking lot. Refreshments will be served, a DJ will provide music, and a face painter will be present. Lennar will also provide shuttle service between the three products, since they are spaced out along the entire site. However unlikely, staff is hoping the traffic signal at Cherrydale Drive will be energized. Edison has additional paperwork that is required before the traffic signal can be energized. If the signal is not energized, Lennar has been asked to prohibit left turns in and out of the development. The left turn pocket has been constructed and it is coned off and by the end of today, "no -left -turn" signs will also be installed. On the day of the event, Lennar may reach out to the Sheriff's Department for traffic control. APRIL 9, 2015 PAGE 6 T&T COMMISSION The formal invitations have gone out to 2000 individuals on their interest list; therefore, a large crowd is anticipated. Final paving will take place tomorrow and once the traffic signal is energized, crosswalk striping will be installed. Additional widening needs to be done over the channel and along Brea Canyon Road; therefore, with this additional street work, new striping may be required. Chair/Carrera asked if Lennar was ahead of schedule in construction. SCE/Young said she could not comment on their schedule. C/Sulakhe asked if the Open House would continue beyond April 18tH SCE/Young responded that she understood the models will be open for public viewing within their operating hours. C/Sulakhe then asked if construction would continue. SCE/Young replied that only the model homes have been constructed. Lennar continues to pull permits to build homes and they are currently on Phase 3 or Phase 4 of each product. The City is issuing finals and Certificates of Occupancy for the models only at this time. Phase 1 for each product has not yet been finalized. C/Pechy asked about the difference between an attached family home and condominium unit. SCE/Young explained that the detached cluster home is essentially a detached condo. If one purchases a detached cluster home, the air space is owned but not a parcel of land. The attached condo is a unit where only the air space is owned but each resident shares a wall with a neighbor. The only product which would include a land lot is the single family residential product (Viridian). J. City Council FY 2015-16 Goals and Objectives — PWD/Liu provided the Commissioners with a copy of the City Council's FY 2015-16 Goals and Objectives. At its March V Study Session, the City Council reviewed the current FY 2014-15 Goals and Objectives. After consideration, the City Council reviewed the list and identified items that had been completed and then directed staff to provide an updated list for approval. Accomplishments for FY 2014-15 include securing national recognition for the SR -57/60 Confluence Project as part of an effort to secure future funding; completion of the right-of-way acquisition for the Lemon Avenue Interchange Project; acquiring the ownership of the Windmill and property on which it sits; and, commencement of the Grand Avenue Beautification Project. Also, in May/June, PWD/Liu will bring a report to the City Council and Commission entitled "Diamond Bar Congestion Report Card" outlining the ongoing effectiveness of the City's Traffic Management System and traffic mitigation projects. PWD/Liu stated that going forward, the City Council Goals and Objectives for FY 2015-16 format has changed and a number of new goals and objectives have been stated. The list includes four sections: 1) Traffic Mitigation; 2) Financial Responsibility and Economic Development; 3) Communications; and, 4) General Items. He read and explained the goals and specific objectives. APRIL 9, 2015 PAGE 7 T&T COMMISSION K. Advocacy Trip to Washington D.C. for the SR57/60 Confluence Project — PWD/Liu explained that this effort began in 2009. On an annual basis, Diamond Bar and City of Industry travel to Washington D.C. to meet with congressional members and staff to emphasize the importance of this project. At a local level, Diamond Bar and the City of Industry have worked closely together with Metro and Caltrans to push this project forward in order to realize improvements to the confluence area. This project is identified in the County's long-range transportation plan; however, funding for the project does not kick in until 2029. The City of Industry has paid for the design and as part of the funding strategy determined that the best way to move forward within our means and resources is to break the project up into phases. The first three phases are fully funded (about $50 million); however, the remaining phases require about $200 million from other resources. Statistics and safety issues prove the seriousness of making these improvements as quickly as possible. The purpose of this year's meeting was very different in that the main purpose was to thank them for their support of the TIGER grant application for $10 million, which represents this project is of national significance. For Diamond Bar and Industry to be awarded this grant is a very big deal. If the USDOT agrees to fund this project, it means they agree that this project needs help. When City representatives visited Washington D.C. last year, we were encouraged by USDOT to give it a try. If the numbers and statistics are so good, there is a good chance that the grant will be awarded. Congressman Royce, Congresswoman Napolitano and Congresswoman Chu offered their support of our application. We presented them with the appreciation plaques along with a copy of the L.A. Times article announcing Diamond Bar and the City of Industry receiving the TIGER grant. Councilmember Jimmy Lin and Industry Mayor Tim Spohn presented the plaques to the three Congressional members and the two California Senators, and staff at the USDOT office. Furthermore, we requested that Congress consider and fund a multi-year transportation legislation. The current transportation bill expires on May 31, 2015. A new bill should finance new freight or goods movement projects such as the Confluence Project. PWD/Liu went on to remind the Commission about the information packet he provided to the Commission for the SR -57/60 Confluence Project. That same information packet was provided to the Congressional members in Washington D.C. Chair/Carrera stated that, with elimination of the earmarks, it requires an extraordinary effort to secure the funding now. It will take a continued concerted effort by the City to secure the funding because otherwise, this project will fall off of their radar and any money that becomes available will go elsewhere. It is a vital project for this area. IX. SCHEDULE OF FUTURE CITY EVENTS: As stated in the agenda. APRIL 9, 2015 PAGE 8 T&T COMMISSION ADJOURNMENT: There being no further business to come before the Traffic and Transportation Commission, Chair/Carrera adjourned the meeting at 7:53 p.m. The foregoing minutes are hereby approved this day of 12015.

Liu, Director of Public Works/City Engineerr�� SUBJECT: DIAMOND BAR ARTERIAL PERFORMANCE REPORT CARD BACKGROUND/DISCUSSION: The Diamond Bar Traffic Management System (TMS) was deployed in early 2009, enabling staff to proactively monitor real time traffic conditions and adjust signal timing as necessary thus enhancing traffic operation and circulation over the last several years. To measure the effectiveness of the TMS, staff retained Fehr & Peers to develop an Arterial Performance Report Card. The attached Technical Memorandum for the Arterial Performance Report Card provides various data collected from 2009, 2011 and 2013 including the 2008 Citywide Daily Traffic Volumes and crowdsourcing (web -based) data. A baseline arterial performance measurements, a comparison of arterial corridor performance between the above mentioned years, and a cost/benefit analysis were conducted. Using vehicle delay (hours) and fuel consumption (gallons), as key performance measures, three (3) layers/levels of operational performance were evaluated: Citywide, corridor -wide, and corridor segment. This Report Card is focused on the results for the entire City and on the arterial corridor level. On an annual basis, the total delay on the City arterials (Citywide) has decreased from 1,168,000 vehicle -hours in 2009 to 1,022,000 vehicle -hours in 2013; while similar trend occurred for total fuel consumption which reduced approximately from 8,680,500 gallons in 2009 to 8,098,900 gallons in 2013. The overall reduction between 2009 and 2013 was approximately 12% in total delay and 7% in fuel consumptions. These total delay and fuel consumption changes were calculated into transportation operation benefits (in dollars), which were then compared to the capital and operational cost (TMS investments) to calculate the returns on investments. Between 2009 and 2011, the total transportation benefits were calculated to be over $4 million based on the delay and fuel consumption savings. On the contrast, the total cost invested on the TMS were approximately $1.2 million, which resulted in a benefit/cost ratio of 3.8. Between 2011 and 2013, the bene-fit/cost ratio was 1.1. Compared to the prior 2 years (2009-2011), the benefits are moderate. In addition to the Citywide arterial performance evaluation, the corridor -level evaluation was also performed on the arterials focusing on travel speeds and travel time along the study corridors during the PM peak hour. A majority of (12 out of 16) arterials have experienced improved travel speeds and reduced travel times in 2011 or 2013, in comparison to 2009, except for eastbound Grand Avenue, northbound and southbound Brea Canyon Road south of Pathfinder Road, and northbound Diamond Bar Boulevard. The overall average travel speed along the arterials has increased from 29 mph in 2009, to 30 mph in 2011, and to 31 mph in 2013. Although the focus of this Report Card is to summarize the Citywide and arterial corridors performance, a web -based GPS tool has also been developed to augment our regular monitoring efforts. This GPS tool contains the relative changes in travel time, speed, delay, and gas cost along roadway segments in the City. These additional details can be used to pinpoint potential areas of concern, if any. Finally, for future updated Report Cards, staff will consider collecting traffic counts on a biannual basis, conduct monthly arterial performance evaluations to address pattern changes for any arterials due to multiple construction activities, and collect GPS routing data in determining increases/decreases in specific route usage over time in Diamond Bar. RECOMMENDATION: It is recommended that the Traffic and Transportation Commission receive, file and concur with staff to forward the Arterial Performance Report Card to City Council.

Diamond Bar Arterial Performance Report Card 0006-0050.03 1. INTRODUCTION The purpose of the Arterial Performance Report Card is to paint a picture of citywide arterial performance by monitoring changes in corridor operational performance and estimating the congestion reduction savings "Benefit" in comparison to the investment "Cost" over time for the arterial street system in the City of Diamond Bar. This monitoring approach has been developed using traffic congestion data collected through big data applications during Congestion Management Program years (e.g., 2009, 2011, and 2013). Key operational performance measures including vehicle delay and fuel consumption were evaluated for three layers: corridor segment, corridor -wide, and City-wide. The operational benefits are reflected as savings and compared to the cost of investment on TMC operations and other improvements to Diamond Bar's signal system. This technical memorandum presents the overall approach, describes traffic input data and methodology applied to the analysis, and summarizes the results, key findings, and recommendations. In addition, a Report Card Summary Brochure (to summarize key findings in a two -fold brochure for decision makers and general public) and a web -based GIS corridor congestion monitoring tool (to provide regular monitoring on City streets including freeways and produce citywide corridor performance report as needed) were also developed as part of this effort. 8141 E Kaiser Blvd, Suite 110, Anaheim, CA 92808 (714) 941-8800 Fax (949) 859-3209 vwa.fehrandpeers.com Diamond Bar Arterial Perr'orniarce Report Card April 2015 Page 2 of 25 20 OVERALL APPROACH The designated Congestion Management Agency (CMA) is responsible for the development, monitoring, and biennial updating of their Congestion Management Program (CMP). The goals of the CMP are to support regional mobility and air quality objec4ves-lay-reducing traffic -congestion; to provide ---a mechanisrn-for-ccrordimdt4Tg—tarrd use and development decisions that support regional economy; and to determine gas tax fund eligibility. In many years, traffic congestion monitoring has been focused on intersection level rather than corridor or area -wide level. The emerging technology in traffic signal control and communications allowed local and regional agencies able to develop more efficient strategies to improve corridor operations through implementation of signal synchronization network and traffic management center for day-to-day operations. However, the corridor performance monitoring was not fully established until the big data become available in recent years. Big data commonly used in the transportation industry typically includes three categories: 1) probe data collected from a portion of the vehicle stream (such as GPS floating car), 2) crowd sourcing data collected using vehicle tracking technology (such as Inrix GPS, TomTom, and Airsage cell phone); and 3) spot data collected from vehicle passing roadside devices (such as Bluetooth, in -pavement loops, video detection, and radar data). For the congestion monitoring purpose, crowd sourcing data (e.g., Inrix) is now commonly used and provides corridor performance traffic data including travel speed, travel time, and bottleneck indicators. Those data can be summarized for corridor segment, entire corridor, and entire study area (e.g., city, county, or state). The approach applied for this Report Card is shown in the workflow on the next page. The green -color box indicates traffic data inputs provided by Inrix, and the output data/results are shown in the orange -color box. The analysis was performed for CMP years (e.g., 2009, 2011, and 2013) and the corridor performance changes between the CMP years (e.g., from 2009 to 2011 and from 2011 to 2013) were then compared to conduct the benefit/cost analysis.

KEY ASSUMPTIONS This section describes the key assumptions applied for the analysis. COMPARISON YEARS To be consistent with the CMP cycles and understanding the City's Traffic Management Center (TMC) was not in full operation until Year 2009, the analysis years were determined to include 2009, 2011, and 2013. In addition, 2009 is the earliest year which has available Inrix data. The two-year period was also able to reduce the influence of land use and economic factors on the analysis. DATA SOURCES A primary indicator of changes in congestion and how this might impact travelers is the observed change in typical travel speeds over time. The travel speed data was collected from Inrix Analytics Suite for each of the three study years. Inrix applies the SpeedWaves approach to determine accurate speeds on arterials (and other roadways) with impediments to free flow from traffic signals, stop signs, traffic circles. In addition to the travel speed, traffic volume data was also obtained from the City. TIME PERIOD The PM peak hour study period was selected for data availability and to analyze traffic data during a time window with typically high levels of congestion. Peak hour traffic data for the weekdays in the month of September were used across all study years for consistency and to reflect conditions while schools are in session. The PM peak hour citywide corridor performance benefits were converted to the annual citywide performance benefits for benefit/cost analysis. Diamond Bar Arterial Performance Report Card April 2015 Page 5 of 25 ANALYSIS LAYERS In order to provide a better understanding of the evaluation results to a broader audience including decision -makers, technical staff, and the public, the operational performance was analyzed and summarized in three levels — for the entire city, for each corridor, and for each major segment. The citywide performance was determined based on the aggregated performance from all the corridors (excluding freeways) within the City's limits. It should be noted that a few corridors in the City's limits do not have historical traffic data from Inrix, therefore those corridors are not included in the Report Card analysis but will be included in the future year Report Card analysis when data becomes available.

KEY TRAFFIC DATA INPUTS This section discusses the traffic data used as the key inputs in the analysis (also contained in the above workflow as the "receive data inputs"). Although GHG emissions data was evaluated as part of this study, understanding changes in emissions requires knowledge of changes in traffic volumes. Since we were limited to one -traffic volumes dataset from 2008, the GHG emissions data for the three CMP cycles was calculated based on the same 2008 traffic volumes dataset. We included the data input with the understanding that this could be an important measure included in congestion studies in the future when more volume data becomes available. TRAVEL SPEEDS V1 -_+ Historical 2009, 2011, and 2013 traffic speed data for Q„ roadways in the City of Diamond Bar were obtained through the Inrix Analytics Suite. We queried the Inrix database to retrieve historical weekday M (Tuesday — Thursday) speeds for roadway segments during the PM peak hour (5:00-6:00 PM) in September 2009, 2011, and 2013. � U W cc TRAFFIC VOLUMES PM peak hour traffic volumes for Diamond Bar roadways were derived from 2008 Average Daily Traffic (ADT) data provided by City staff. The data obtained through the City consists of 24-hour volumes which needed to be converted to peak hour volumes. A comparison of PM peak hour and daily counts at certain City intersections where we have both traffic counts indicates an approximate peak hour -to -daily traffic ratio of 10%, which was applied to all roadway segment daily volumes to obtain the PM peak hour volumes. Figures 2-A and 2-113 show the 2008 daily traffic volumes in the Diamond Bar area.

This database, released by the California Air Resources Board (CARB), provides emission rates for various greenhouse gases, including carbon dioxide. These rates are further categorized according to vehicle model year, vehicle type, and fuel type. For the purposes of this analysis, vehicle model years were aggregated and 2009 light duty emission rates were used for passenger vehicles using gasoline. Due to limited traffic volume data availability, Greenhouse Gas Emission data was retrieved but not applied in the congestion analysis. The CO2 emission and fuel consumption rates by travel speed bin used for this analysis are presented in Table 1 below.

The fuel consumption rates by travel speed bin used for this analysis are presented in Table 1 above. FUEL PRICES The US Energy Information Administration provided detailed fuel prices for each month and week going as far back as January 2000. Given that the historical fuel price data was provided for the Los Angeles County and the historical data for Diamond Bar is not available, the historical fuel prices for LA County was used for the analysis years, which was approximately $3.9-4.0 per gallon. CAPITAL & OPERATIONAL COSTS The capital and operational costs that occurred in the analysis year of 2009, 2011, and 2013 were provided by the City of Diamond Bar, which include the TMC installation cost, routine maintenance costs, the TMC operations/system maintenance costs, Battery Back- up (BBS) costs, and CCTV video camera costs. The cost information was used to conduct the benefit/cost analysis between the three years which will be discussed toward the end of the report. Diamond Bar Arterial Performance Report Card April 2015 Pace 12 of 25 5, CONGESTION INDICATORS AND METHODOLOGIES The Report Card workflow uses on -the -ground data inputs to better understand congestion within a transportation network as well as how traffic patterns change over time. This study used data sources described it t e-pr_ovious_�c-tion ta_calCLIIate_multiple_ indicators of congestion in the City of Diamond Bar. Changes in these indicators across the study years were calculated by subtracting each metric between the years. Below is a description of each indicator used in the Report Card workflow. TRAVEL TIME � O About the Indicator. V Congested conditions can be characterized by slower 4-J travel speeds and longer travel times than would be faru O experienced during periods of relatively low demand. u O ra Travel time as measured during typical conditions can U tn N be used to monitor congestion in a study area over 0) time. CO V VMT Delay Methodology: Travel times for study segments in the Congestion Report Card study area were calculated using travel speed data from Inrix. For each study period, Inrix data was filtered to include only speed samples collected on Tuesday, Wednesday, and Thursday in the month of September between 5:00 PM and 6:00 PM. Since the Inrix data was provided along relatively short segments, these segments were aggregated according to "Logical Segments": longer segments with logical start and end points based on geography, typically where intersections with other major roadways occur. Data were also summarized by "Corridor", where entire lengths of freeway and street were analyzed to provide metrics for an entire roadway. O Diamond Bar Arterial Performance Report Card April 2015 Paqe 13 of 25 VEHICLE MILES TRAVELED (VMT) About the Indicator: Changes in VMT can indicate the increased/decreased usage of a Logical Segment or Corridor over time, which may indicate growing demand and help identify potential focus areas for future traffic management efforts. VMT is also an important indicator of transportation network performance according to the new CEQA guidelines contained in the Senate Bill 743 (SB -743). Methodology: For this analysis, VMT was calculated by multiplying peak hour roadway volumes by roadway lengths. For all three study years, 2008 peak hour volumes were used to calculate VMT due to limitations in data availability for other years. Therefore, VMT is not the focus for the analysis of this round Report Card but should be considered for the future year Report Card analysis and other transportation planning analysis. DELAY About the Indicator:- Delay is measured by comparing the theoretical travel time along a study segment in ideal conditions to observed travel times. Analyzing changes in delay over time can provide valuable insight when assessing the extent to the influence of TMC and other signal system improvements on traffic congestion. Methodology: Delay was calculated by subtracting the freeflow travel times from Inrix data with the recorded travel times for Logical Segments and Corridors for all the analyzed corridors in the City of Diamond Bar. TRAVEL COST About the Indicator: Increased travel costs may be experienced by travelers using congested facilities. Understanding where travel costs are relatively high or low in an area improves the ability to identify areas wherein management efforts have improved conditions as well as Diamond Bar Arterial Periormance Report Card April 2015 Page 14 of 25 areas that may need attention. Typically travel costs consist of two types of costs: 1) delay cost associated with the travel time delay experienced by travelers; and 2) gas cost associated with fuel consumption for the travel. Methodoloay: Delay cost was calculated by multiplying the total hours of delay by hourly labor rate (e.g., dollars per hour). Based on the 2014 Tiger Benefit -Cost Analysis (BCA) Resource Guide prepared by Department of Transportation (http://www.dot.gov/tiger), an average hourly labor rate of $20 was applied to this study. Gas cost was calculated based on the fuel consumption and historical fuel prices obtained from US Energy Information Administration for the LA County as described in the previous section. Travel costs were then calculated using the sum of delay costs and gas costs for each Logical Segment, Corridor, and the City. Table 2 on next page summarizes the brief descriptions, data sources, calculation methodologies, and purpose of all the traffic input data and indicators used for the Report Card analysis. In addition to the congestion indicators described above, the other following indicators/performance measures will be evaluated for consideration in the future year congestion monitoring effort. • Level of Service • Intersection Queue Lengths • Hot Spots/Bottlenecks • Person Miles of Traveled Diamond Bar Arterial Performance Report Card April 2015 Page 15 of 25 Table 2 Description of Study Segment Attributes Data Field Description Source/Calculation Purpose Segment Length Length of the segment in INRIX Input miles Measured vehicular travel Segment Travel Time time across the segment in INRIX Indicator minutes Measured average speed of Segment Speed vehicular travel in the INRIX Indicator segment in miles per hour Average freeflow speed of Reference Speed vehicular travel in the INRIX Input segment in miles per hour Average number of vehicles City of Diamond Bar ADT and Volume passing through the peak -to -daily traffic ratio from Input segment between 5:00 PM peak period intersection and 6:00 PM (weekday) counts: (ADT*10.35%) Travel time across segment (Segment Length)/ (Reference Freeflow Travel Time based on freeflow speed in Speed) Input minutes Delay Delay per vehicle, based on (Freeflow Travel Time) — Indicator freeflow conditions (Segment Travel Time) VMT Vehicle miles traveled on (Segment Length)*(Volume) Indicator segment Estimated cost of gasoline Cost of Gasoline' on segment, based on Fuel consumption*$3.5 dollars Indicator dollars per mile by speed per gallon bin Estimated CO2 emissions by VMT*(Grams of CO2 per mile CO2 Emission segment, based on lookup table — see Table Indicator emissions per mile by speed 1)*2.2046/1000 bin Estimated fuel consumption Fuel Consumption on segment, based on VMT*(gallons per mile lookup Indicator gallons per mile by speed table — see Table 1) bin Notes: 1.

RESULTS & FINDINGS The final step of the Report Card workflow is to estimate savings and changes in congestion between—sturfy--years._ _T -able -3 below -shows -the two major -performance - measures (delay and fuel consumption) for each of the analysis years during the PM peak hour and on an annual basis. During the PM peak hour, the total delay on the analysis City streets has decreased from 320 vehicle -hours in 2009 to 280 vehicle -hours in 2013; while similar trend occurred for total fuel consumption which reduced approximately from 2,400 gallons in 2009 to 2,200 gallons in 2013. On an annual basis, the total delay on the analysis City streets has decreased from 1,168,000 vehicle -hours in 2009 to 1,022,000 vehicle -hours in 2013; while similar trend occurred for total fuel consumption which reduced approximately from 8,680,500 gallons in 2009 to 8,098,900 gallons in 2013. The overall reduction between 2009 and 2013 was approximately 12% in total delay and 7% in fuel consumptions.

The results are summarized in Table 4.

On the contrast, the total costs the City invested on TMC installation, TMC maintenance, and BBS were approximately $1.2 million during the two years. This resulted in a ratio of benefit/cost of 3.8 between 2009 and 2011, and the significant operational benefits were largely caused by the TMC in full operation and also partly resulted from the steady traffic demand due to economy in the "down" time. The operational benefits between 2011 and 2013 are moderate compared to the prior two years due to increased traffic demand on City streets as economy got better. However, the overall transportation benefits gained between 2011 and 2013 were still higher than the costs by approximately $100,000. Diamond Bar Arterial Pe iormance Report Card April 2015 Paste 18 of 25 Amer°ial Cavvidar-Level Evaluation In addition to the citywide arterial performance evaluation, the corridor -level evaluation was also performed on the arterials focusing on travel speeds and travel time along the study corridors during the PM peak hour. The comparison in travel speed and travel time between 2009, 2011, and 2013 is summarized in TaWe S. As shown, a majority of (12 out of 16) arterials have experienced improved travel speeds and reduced travel times in 2011 or 2013, in comparison to 2009, except for eastbound Grand Avenue, northbound and southbound Brea Canyon Road south of Pathfinder Road, and northbound Diamond Bar Boulevard. The overall average travel speed along the arterials has increased from 29 mph in 2009, to 30 mph in 2011, and to 31 mph in 2013. Figures 3 throw display the average speeds for each of the arterials during 2009, 2011, and 2013, respectively. Figure shows the speed changes between 2009 and 2011, while the speed changes from 2011 to 2013 are shown in Figure 7.

The web -based GIS tool contains the relative changes in travel time, speed, delay, and gas costs along roadway segments in the City of Diamond Bar. These segment level results provide additional details that will be used to help pinpoint potential areas of concern if any. For example, Grand Avenue in the eastbound direction showed an average speed of 27 mph for the corridor as a whole during the PM peak hour in 2013; however, the Grand Avenue segment near the SR -57/60 interchange showed a speed of lower than 20 mph, the segment east of the interchange to Diamond Bar Boulevard had a speed of 20-30 mph, and Grand Avenue east of Diamond Bar Boulevard showed a speed of 30 mph or above. The segment -level data helps to identify potential hot spots along the corridor, and in the case of Grand Avenue eastbound, the segment -level speeds indicated the hot spot for Grand Avenue was near the SR -57/60 interchange in the PM peak hour. Diamond Bar Arterial Performance Report Card April 2015 Paqe 25 of 25 7. RECOMMENDATIONS This Arterial Performance Report Card provides a baseline 2009 arterial operational performance evaluation, a comparison of corridor performance between 2009, 2011, and 2013, and benefit/cost analysis to provide a better understanding of the returns of investments to general public and decision makers. The following list includes recommendations to consider for future Report Cards: • Future Data Collection: Future Report Card studies would benefit from up-to- date traffic count data for study segments in the area where city staff anticipate changes in usage in the future. We recommend collecting traffic counts on city's streets on a biannual basis, and the next round of traffic counts collection is scheduled to be in September 2015. • Construction Monitoring: Multiple construction activities are beginning or will begin soon in the City of Diamond Bar, which will likely result in significant traffic pattern changes for various City streets. We recommend collecting arterial speeds and monitoring arterial performance more frequently (e.g., monthly) during the construction period and providing effective traffic management solutions/strategies before concerns arise from residents and business owners. • Incorporation of Routing Data: Additional big data resources such as GPS routing data could be useful in determining increases/decreases in specific route usage over time in Diamond Bar. This could help identify potential focus areas in conditions that may encourage drivers to seek alternative routes, especially during construction or when accidents occur. We recommend collecting GPS data which is used to understand the usage of specific routes and develop strategic signal timing improvements to achieve balanced use of the routes to relieve congestion for certain routes by diverting traffic to alternative uncongested routes. - MIS. li"iiiiltialwili _ s # — wommilm r_ N L � • � cc G O V U E L � e a � � i 1 tco L 0 Ln W t^ G L Q V Y'13 LO N 3 > C ° 3 H .o 4 0 4- O -o a -�v o 13 O O N r6tn M _ 4J lowm L. a O oC oC a aC # — wommilm • • :. �.:,:a Ion 4-J r V > —> Q4-' - -� E r0 c L � an eon low to (A _MEMO c O i V (A m c O .N' a.
