6.8.7 Advance Detection

In Australia, detectors located in advance of the stop-line for the purpose of detecting moving vehicles (passage detection) are usually used on safety grounds, (i.e. at sites where approach speed is high and particularly when there is a large proportion of heavy vehicles). For this purpose, they should be located to suit the stopping distance required for the 85th percentile approach speed, where possible.

Advance detection can also be used to provide signal priority for buses and trams.

For additional guidance on the use of advance detection, refer to Commentary 9.
