2014 Traffic Signal Synchronizations – Great Results

Cutting congestion and gridlock remains my number one priority as Chair of Public Works.

That’s why I’m pleased to share the results of the city’s 2014 Traffic Signal Coordination Program.

In 2014, the city synchronized 224 traffic signals on 7 major corridors, including Yonge, Leslie and Sheppard.

The results were impressive, including:

  • A 10% decrease in overall vehicle delay;
  • A 4.5% decrease in fuel consumption (equivalent to the CO2 emissions from 693 homes’ electricity use for one year!); and,
  • A 4.6% decrease in emissions.

Overall, the 2014 work resulted in an estimated annual savings of nearly $17 million in reduced congestion-related costs.

Signal synchronisations also offer a great return on investment. The benefit-cost ratio of the 7 major corridors retimed in 2014 was 63 to 1!

Better yet, there’s more in store for 2015. 343 synchronizations on 11 major corridors are scheduled this year, bringing the four year synchronization total to nearly 1,000 since the program began in 2012.

Traffic Signal Synchronization

As part of a five-year plan to improve traffic flow on Toronto streets, the City will be revaluating and coordinating approximately 1,000 traffic signals across the city. The project involves connecting traffic signals to the city’s Traffic Management Centre to allow for better timing and synchronization.

The plan also includes upgrades to Toronto’s traffic signal management system by the end of this year; installation of 100 traffic cameras on arterial roads to better detect problems; 13 additional message signs on the Don Valley Parkway and Gardiner Expressway and better management of the use of curb lanes.

In 2014, city staff will review and retime 15 signals along Yonge Street between the 401 and Eglinton as well as ten signals along Leslie Street between the 401 and Eglinton. These upgrades are scheduled to be completed by the end of 2014. To report problems related to signal coordination, you can dial 311 or visit to reach the city’s 24-hour help line!
