Solution
Clearview Intelligence worked alongside Kier and Carnell to design a long vehicle detection system that would operate across the junction and trigger the VAS further up the road.
As part of the solution Clearview had to overcome a number of technical considerations including no mains power to the junction detection loops, and that the VAS would be positioned some 300 metres away, meaning remote triggering of the sign activation would be required.
The junction vehicle detection loops and the M680 Vehicle Detection System are powered using a Clearview Intelligence MtPole Solar Panel Roadside Cabinet. The 80w solar powered panel overcomes the lack of mains power at the junction and is fitted with a GSM antenna for radio communication with the VAS.
An innovative bespoke solution was also required to enable the M680 to only trigger the VAS when a long wheel base vehicle was at the junction. This was a significant technical achievement given the slow, stop / start nature of the traffic. The programming also included consideration for when multiple long vehicles are detected and the VAS is required to remain on for longer.
Since the solution has been in place there has been a noticeable change in the speed and behaviour of drivers along the A590 on the approach to the Foulshaw Junction. Local residents have also been quick to notice the change, commenting on how well the system is working within early stages of operation.
