3. Typically a Regional network consists typically of 3 to 12 traffic signals and is coordinated by time of day to provide the least amount of delay to the heaviest traffic movements A balance is derived between side street delay and main street progression The intention is to provide main street traffic with optimized green bands to suit the desired progression pattern The Region of Peel expects that the review of any existing network or addition of a new traffic signal within an existing network adhere to this philosophy and follow patterns established by the Region Furthermore it is required that prior to any traffic signal optimization there is initial consultation with the Regional Technical Analyst The Region of Peel does not require unless specified by the respective Regional Technical Analyst appointed to the project any modification of signal timings by consultants other than that of a new traffic signal New intersection timings and offsets are to be calculated to ensure the same level of network progression In the circumstance where the optimization of traffic signal networks is specified further consultation with the Regional Technical Analyst may be required Any modifications to existing signal timings as specified by the Regional Technical Analyst require adjusted offsets to maintain progression and avoid the eroding of existing network signal progression Please refer any questions to Joseph Lynn Technical Analyst Traffic S

8. chro From our initial experience the simulated traffic animations provide a good visual representation of existing and future impacts It should be noted that the animation software could produce results that are contradictory to reports created in Synchro and as such caution should be used Network animation will attempt to provide realistic macroscopic scenarios that incorporate the entire network In network simulation individual intersection simulation results may operate differently than expected due to traffic gating and other general network constraints Therefore to observe individual intersection animation it may be appropriate to simulate an individual intersection independently rather than in a network In view of that animation of individual intersection operation within a network is not wrong however provides a macroscopic perspective of the entire network In either case engineering judgement should be applied when evaluating any simulation
