M42 Jct 3a - Jct 7 Active Traffic Management
How does the system know what to do?
The sensors located in the road surface detect the amount and flow of traffic. The computerised system uses this information to calculate the best speed to keep traffic flowing smoothly. This speed is then displayed as a mandatory signal on the speed limit signals overhead.
The Active Traffic Management operator, based in the Regional Control Centre, is also able to control the speed limits and driver information signs. The system alerts the operator to increases in traffic and the operator is able to view the scheme using the CCTV cameras that cover the whole stretch of the M42 junction 3A to 7.
