How Many Traffic Signals are in York Region?
  • York Region operates and maintains approximately 700 traffic signals.
  • The local Municipalities maintain approximately 100 more.

Most of these Region's signals are connected to the
Centralized Traffic Control System.

How are Signalized Intersections Timed?
The Regional Municipality of York uses several timing plans to co-ordinate signals to move the flow of traffic.  These periods are generally:
  •  AM Peak: 7 a.m. to 9 a.m.     
  •   Off Peak: 9 a.m. to 4 p.m., and 7 p.m. to 11 p.m.
  •   PM Peak: 4 p.m. to 7 p.m.
  •   Overnight:  11p.m. To 7 a.m.

These timings are implemented Monday to Friday.  Weekend plans are used upon demand as traffic patterns change.

Traffic patterns are identified by:
  • Approximately 300 traffic counts completed at intersections every year
  • Approximately 500 traffic counters with pneumatic tubes placed in between intersections
Timing of signalized intersections is based on vehicle volume demands, with the majority of time given to the demand requirements.  This operation holds the intersection in "Major Street Green" state until such a time as the coordination terminates to the minor street if the demand is present.
Advance arrow phases are developed for intersections on a case by case
basis, and must meet the needed requirements. These advance phases are either omitted or added depending on the impact they may have on opposing traffic flow.
 
During the overnight period, intersections run in "free" mode and traffic signals are not coordinated.  This allows for a much quicker turnover to the minor street.  The phasing on the minor street will turn green and run the minimum green time, which is generally 10 seconds.  If there are no additional presences of vehicles it will terminate to the major street.  However, if more vehicles are detected it will run to its maximum time, generally 30 seconds.

How are Vehicles Detected?
A Loop detector is embedded into the pavement at minor street approaches and in left turns lanes.  The passage of an electrical current through the loop generates a magnetic field around it.  As a vehicle approaches a loop, this disturbs the magnetic field and causes the inductance of the loop to change, therefore, activating the alternate phase.
