One of the fundamental parts of the City’s Congestion Management Plan 2016 – 2020 is to maintain signal timing plans to ensure they are up-to-date and responsive to the needs of all road users. The aim of the City’s Signal Optimization Program is to undertake signal coordination studies on a five-year cycle for major arterial roads, and on a ten-year cycle for minor arterial roads. Within the five-year cycle, a one-time study may be required for a portion of the route if there are significant changes in traffic volumes or land use. Coordination studies are not undertaken for traffic adaptive systems, such as SCOOT.

The City uses Synchro® software to develop optimized signal timings plans. Studies are done in conformity with the City’s Guidelines for Using Synchro 9 (including SimTraffic 9).
