COOPERATIVE AGREEMENT NO. C- 3.2084 ATTACHMENT A KRAEMER BOULEVARD / GLASSELL STREET! GRAND AVENUE -- TSSP Appropriate cycle lengths consistent with the goals of this effort. Additionally, CONSULTANT shall recommend time -of -day start and stop intervals for the various timing plans based on the Identified peaks from the 24 -hour machlne counts, and field observation. o .CONSULTANT shall prepare, at minimum, a total of.three (3) timing plans. for..a typical weekday which consider the following peak periods: AM PEAK, MID -DAY PEAK, PM PEAK and one (1) timing plan for a typical Saturday for a MID -DAY PEAK. Timing plans should be in both Synchro format and the preferred timing chart format of each local AGENCY. CONSULTANT shall develop an operational model within SlmTraffic. The operational analysis will be used to micro — simulate and analyze specific roadway segments with queuing, spill back, starvation, storage blocking, and other queuing interactions, and to analyze and mitigate the conditions discovered by CONSULTANT and /or APM and AGENCIES in field reviews. CONSULTANT shall develop optimized signal timings using the results from PTV Vistro 2 and/or Synchro /SimTraffic 8.0, in conjunction with Tru- Traffic version 10.0 or latest released version and recommend any changes to the signal phasing at each signalized intersection that may Improve the efficiency of operations. Output of the modeling software shall not be utilized without proper QA/QC. Engineering judgment shall be utilized to determine final operational parameters. The recommended signal timing plans shall be reviewed by the APM and local AGENCY staff. Time of Day /Day of Week (TOD /DOW) Timing Plan selection schedules shall be developed that reflect actual traffic conditions within contiguous segments or down to the individual Intersection as necessary. The CONSULTANT, in cooperation with the APM, and upon concurrence of the Traffic Forum, shall develop a real time traffic responsive operations (TRO) program to facilltate timing plan selection based on data obtained from the project. The program shall select the timing plans relative to volume, occupancy, speed, if available, and directional flows on a 24hour /7 days per week schedule, All forms of detection for all modes of travel may be employed in this endeavor. A library of timing plans shall be developed to facilitate this requirement. A static TOD /DOW schedule shall be developed and set ready as backup in case of detection failures within the TRO program Upon approval of the optimized signal timings by the Authority and the cities, the CONSULTANT shall implement, or assist local AGENCIES staff in the implementation of new signal timings either through the central traffic signal system (if available) or direct implementation at the intersection controller units. CONSULTANT shall use existing traffic signal interconnection systems, where they exist, and, as a result of the inter- jurisdictlonal nature of the project, shall implement time - based signal coordination techniques across signals controlled by different AGENCIES. As the project will be using time -based signal coordination, the CONSULTANT shall evaluate the current time - referencing of all traffic signal controllers and recommend a corridor -wide strategy to ensure that all traffic signal controllers are on synchronized time clocks linked to a master time source, CONSULTANT shall verify that all Central Master or Local Field Master, and /or Local Controller unit clocks are: • operating properly and are synchronized; • and that all clocks are referencing a Coordinated Universal Time (UTC) and the start for all cycle length Calculation shall be 12:ODAM — Midnight.
