Traffic Control Device Timing

Keep hearing I can't stop, not enough time etc... Interesting is the Minimum times.....I have yet to see any light at that little of time, the lights where I live all have 4 sec amber and 2 sec all red.


This is a suggested way on how to set up traffic control device timing - I will post below, but here is link

http://www.bv.transports.gouv.qc.ca/per ... aining.pdf

Timing - Minimum Interval Timing


LIGHT - desirable minimum seconds - acceptable minimum seconds

- amber 2.0 seconds - 1.5 seconds

- all red 1.0 second - 1.0 second


Calculation of clearance interval (amber interval clearance and all-red interval clearance) is based on approach operating

speed, the motorists perception and reaction times, the crossing width and the average deceleration rate of the vehicles

clearance = Amber + All-Red

Amber indicates to the driver that the right-of-way is about to be changed and therefore must provide sufficient time for the

approaching motorist to travel the Stopping Sight Distance


The all-red interval represents the time required to provide a safe passage across the intersection for vehicles entering the

intersection at or near the end of the amber interval.

Historical note... the person who "invented" the amber light (actually, the three-colour traffic signal) was a cop: William Potts, of the Detroit Police.
