Re-design the proposed signal at A. W. Grimes at Creek Ridge Blvd. at 90 percent plan submittal stage. The re-design will include the following changes: a. Update "Proposed Signal Layout" sheet to change single mast-arm pole assemblies to dual mast-arm pole assemblies. b. To counter sight distance and visibility issues, add an advanced flashing beacon assembly to inform motorists of a possible stop at the new signal ahead. c. Update"Conduit and Cable Chart" sheet based on updated signal pole locations. d. Update "Wiring and Phasing" sheet. e. Update "Signal Elevation" sheet. f. Update "Quantities" sheet. 2. Update signal design plans to include flashing yellow arrow signal head displays for all left- turn movements at University Blvd. at Teravista Club Dr., Sandy Brook Dr., and College Park Dr. The following modifications will be made at each intersection: a. Update "Wiring and Phasing" sheet. b. Update "Signal Elevation" sheet. c. Update"Quantities" sheet. d. Using SignCAD design a new 24"00" plaque sign to be installed next to a flashing yellow arrow signal head display. 3. Add three new sheets to the planset to include the upgrade of existing signals at University Blvd. at University Oaks Blvd., Oakmont Dr., and Sunrise Rd. installing flashing yellow arrow displays for left-turn movements. 4. Estimate quantities to upgrade existing signals along FM 3406/Old Settlers Blvd. and Gattis School Rd to include flashing yellow arrow displays for all left-turn movements. The signals will include six (6) existing signals along FM 3406/Old Settlers Blvd. and 12 existing signals along Gattis School Road. In addition to the above services, KHA will provide coordinated signal timing plans for AM Peak, PM Peak, Off-Peak, and Weekend-Peak periods for six (6) existing signals and three (3) proposed future signals along University Blvd. The detailed scope of services is as below: TASK 8.0 DATA COLLECTION KHA will collect turning movement counts at the intersections listed below along University Blvd. Corridor. The counts will be collected on a Tuesday or Wednesday from 7-9 AM (morning peak), and 4-6 PM (afternoon peak). 05/01/12 Traffic Signal Designs Supplemental 1 2 City of Round Rock 1.

Seton Parkway 5. Sunrise Rd. 10. A. W. Grimes Blvd. Subtask 8A. Field Observations KHA will monitor operations at critical signals which will be determined in consultation with the City staff. KHA will identify and note any operational challenges and improvement potentials at these intersections. Subtask 8B. Intersection Data KHA will collect existing lane geometries, traffic control, speed limits, and signal phasing information for each corridor and intersection listed above. Subtask 8C. Photo Log KHA will photograph the approaches to each intersection for verification of field data. These photographs will be provided as an appendix to the final report. Subtask 8D. Daily Traffic Volumes KHA will collect directional 24-hour tube counts at up to two locations to determine daily and weekend traffic peaking patterns along the project corridor. Subtask 8E. Travel Time Runs KHA will collect existing travel times from one end of the project corridor to the other end during AM Peak, PM Peak, Off-Peak, and Weekend Peak periods. KHA will use this data to compute delay savings after implementing proposed optimized signal timings along the corridor. TASK 9.0 DEVELOP SYNCHRONIZED SIGNAL TIMING PLANS KHA will perform the following tasks to develop synchronized signal timing plans for the corridors listed in Task 8.0: Subtask 9A. Base Models KHA will develop base models using traffic simulation software Synchro 7.0 with existing signal timings, lane geometries, and roadway speeds. Models will be created for each of AM Peak, PM Peak, Off-Peak, and Weekend-Peak periods. 05/01/12 Traffic Signal Designs Supplemental 1 3 City of Round Rock Subtask 913. Cycle Length Analysis After setting up the base models, different cycle lengths will be analyzed using Synchro 7 to identify the optimum system cycle lengths and lead/lag sequences for the corridor. The optimum cycle length for the diamond interchange at IH-35 and University Blvd. will be determined using PASSER III software. Subtask 9C. Optimized Models Optimized splits, offsets and phase sequences will be developed for the corridor to maximize green bands for the AM, PM, Off Peak, and Weekend Peak period. The off peak period will be modeled by factoring down the afternoon model using data from the 24 hour counts along the corridor. The green band splits will be based on peak period traffic demand, with larger green bands favoring predominant traffic flows. The new timing plans will be discussed with City staff for their review and approval. Modifications will be made to the timing plans based on the City's comments and a set of timing plans and time- space diagrams will be presented to the City. TASK 10.0 SIGNAL TIMING IMPLEMENTATION AND FINE TUNING KHA will assist in the implementation of the signal timing plans as follows: Subtask 10A. Lab Test Each individual timing plan will be downloaded to a test controller at the City's traffic shop for testing prior to implementation to prevent any glitches upon implementation in the field. Subtask 10B. Input New Timings KHA will input the proposed signal timing plans at each signal using new `pattern' numbers preventing the need to overwrite existing coordination pattern. The initial implementation of the timing plans will be done remotely via the City's ACTRA/TACTICS system to increase efficiency of programming the controllers. Subtask 10C. Fine Tuning After the proposed signal timing plans have been implemented, KHA will drive'through the corridor during each peak period (AM, Off-Peak, PM, and Weekend peak) to identify any modifications that need to be made to the splits and or the offsets. Attention will be paid to vehicular delays and queuing on minor streets. Upon completion of the fine tuning, KHA will update the City's ACTRA/TACTICS database and deliver final timingplan sheets to the City. f 05/01/12 Traffic Signal Designs Supplemental 1 4 City of Round Rock A TASK 11.0 FINAL REPORT AND MODEL SUBMITTALS KHA will prepare a technical report detailing the methodology adopted, assumptions, and the results of the study. The report will include a `Before' and `After' analysis measuring the overall improvement to each corridor in terms of travel time savings and reduction in pollutants with the deployment of new signal timing plans. Additionally, numerous appendices providing details of the data collection efforts, signalized intersection reports using the Highway Capacity Manual (HOW reporting feature of Synchro 7,time-space diagrams, and timing sheets will be included as part of the report. KHA will submit three (3) draft copies of the report to the City for review. Within ten (10) working days of receiving review comments, KHA will finalize the report and provide three (3) copies to the City. All reports will be signed and sealed by a Texas registered professional engineer. All Synchro 7 models will be submitted to the City at the completion of the project. i i 3 x x f d r F k F E 05/01/12 i Traffic Signal Designs Supplemental 1 5 City of Round Rock EXHIBIT C UPDATED WORK SCHEDULE Kimley--Hom and Associates,Inc.
