Frequently Asked Questions


Q - How do I report a traffic signal light not working?
A - Contact 311

Q - How are traffic signals warranted?
A – The traffic signal warrant procedure considers pedestrian and vehicle volumes, intersection characteristics and adjacent land uses.  To assess an intersection for the installation of a traffic signal, a six hour pedestrian and vehicle count is undertaken. The typical count hours are 7 a.m. - 9 a.m., 11 a.m. - 1 p.m. and 4 p.m. - 6 p.m. A minimum warrant score of 100 points is needed for a signal to be considered as warranted.

Q - How are vehicles detected at traffic signals?
A – Vehicles are detected by inductive loops placed in the roadway which sense the variations in the magnetic field influenced by the presence of a vehicle. Video cameras, microwave detectors and magnetometers are also used to detect vehicles.

Q - Why does the signal turn green for a side street when no one is there?
A – There could be a problem with the vehicle detection or pedestrian push button. An emergency vehicle may also be approaching the intersection and the traffic signal could be giving priority to the approaching emergency vehicle.

Q - What is a roundabout?
A - The modern roundabout is an intersection designed to control traffic in a circular flow. It is economical and reduces overall traffic delays. Traffic moves in a counter-clockwise direction around a central island. Emergency vehicles can quickly and safely pass through roundabouts and noise pollution is decreased as well.
