General Traffic Signal Information:
There are over 690 signalized intersections within the City of Mississauga that are controlled by the City's Central Traffic Computer System. This includes intersections under the jurisdiction of the Region of Peel, Ministry of Transportation Ontario, Halton Region and the Greater Toronto Airport Authority. The Traffic Signal and Street Lighting Section is responsible for the construction, maintenance and operation of signalized intersections under the City's jurisdiction.

New Traffic Signal Requests:
The City of Mississauga uses guidelines set out in the Ministry of Transportation Ontario's TRAFFIC SIGNAL WARRANT to determine when new traffic signals should be installed. The warrant takes into consideration the following:

• Total Intersection Volume
• Pedestrian Movements
• Collision History

Traffic Signal Timing:
The Traffic Signal and Street Lighting Section is responsible for the timing and efficient operation of signalized intersections under City jurisdiction. Each year the department responds to hundreds of requests for new left-turn phasing and other timing/operational issues. Each request is reviewed and stored in files specific to the intersection for future reference.

There are two levels of signal timing:

• Intersection Signal Timing
• Network Signal Timing

Intersection Timing:

Intersection specific signal timings are developed for each intersection based on its individual characteristics. These timings include:

• Minimum and maximum times for vehicles by direction
• Pedestrian timing
• Clearance intervals (amber, all red)
• Left-turn signal timing

Clearance Intervals Signal Timing (Amber, All Red):
The amber signal indication is a warning to drivers that their right-of-way is about to be terminated and assigned to conflicting traffic. The all red indication occurs when all displays at the intersection are red and is intended to give time for vehicles in the intersection to clear before the conflicting green indication is displayed. The City of Mississauga calculates the clearance interval based on guidelines set by the Ministry of Transportation Ontario.

Network Signal Timing:
The goal of network based signal timing is to coordinate traffic progression through a series of traffic signals on a section of roadway. Timing plans are created based on time of day and traffic volumes.
