M42 Jct 3a - Jct 7 Active Traffic Management
What happens in congestion?
When the early signs of congestion are detected on the M42 Active Traffic Management scheme, the control centre operator and automatic system will change the signs and signals to alert road users to the conditions ahead.
The system automatically calculates the best speed to keep the traffic flowing and then this is displayed on the speed limit signals overhead.
The control centre can also open the hard shoulder, under controlled conditions, as an extra running lane to reduce the impact of congestion by providing extra space for the traffic. This will help to keep the traffic flowing and minimise delays.
