Red light Runner Surveys

Three distinct techniques exist for this survey:

• Manual observation
• Video Camera
• Data Logger.

ATS can apply the application of it's data loggers to detect traffic signals on a red phase, either by direct connect to the signals or passive optical sensing of a red signal, in conjunction with an axle sensor on the departure side of a stop line.

This system can identify the frequency of red light running events and or usage of a second axle sensor post stop line can classify the vehicle type and speed post stop line. The more useful information at this instant is vehicle type and knowing if a car or type derivative is at fault.
