Arterial Analysis. The Arterial Analysis will form the basis for recommended improvements intended to control access, reduce travel time, delays and queues, enhance safety, manage and/or reduce conflicts, enhance positive guidance, and improve overall operational and traffic flow characteristics. At a minimum, this will include traffic counts, an arterial inventory and a crash analysis. The CONSULTANT may be required to determine the need for new or upgraded transportation facilities services within a corridor. The CONSULTANT may be required to perform large area traffic flow and transit ridership analyses as needed to evaluate various multi-modal improvement alternatives within a corridor. The CONSULTANT may be required to evaluate the impact of improved public transportation on traffic LOS and "person trips" within specified corridors. The CONSULTANT may be required to identify critical corridors and recommendations on improving corridors, including but not limited to the applicability of transportation demand reduction strategies.
Arterial Analysis. The CONSULTANT shall use latest approved version of the SYNCHRO computer software to determine the optimal phasing, cycle length and splits. Engineering judgment should always be used in correlation with the software. This is the task where the CONSULTANT actually develops the timings plans for the arterial in SYNCHRO. TRU-TRAFFIC (Time-Space/Platoon Progression Diagram Generator) shall be used by the CONSULTANT to refine the offsets from the time-space diagrams generated by SYNCHRO. The bandwidths, speeds, direction of travel, intersection names and offsets shall be shown on each time-space diagram developed in TRU- TRAFFIC. The CONSULTANT shall develop five (5) traffic control timing patterns for each arterial listed in the Work Order which shall include AM Peak, PM Peak, Off Peak, Evening and Late Night weekday and weekend patterns. The plots of the volume summary information gathered in Tasks 1 or 2 shall be used to graphically indicate the time of day operation plans for each system. The results of the SYNCHRO analysis and TRU-TRAFFIC time-space diagrams shall be submitted to the City as Draft Timing Plans for review and approval prior to proceeding with the timing implementation. Upon approval, the Draft Timing Plans shall be used as Initial Timing Plans prior to fine tuning.
