Three distinct techniques exist for undertaking surveys involving vehicles that run red lights or rail crossing signals and barricades.
- Manual observation
- Video Camera
- Data Logger
Austraffic can apply the application of its 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.
