Many councils are faced with a problem which is all too familiar to local authorities across the country, how to reduce the speed of traffic without the need for expensive road layout changes or tying up valuable police resource. The Suilvision solution gives drivers a reminder that they are in a casualty reduction zone. The system includes a Variable Activated Sign (VAS) which has the ability to display a vehicle registration number as well as provide a reminder to the driver that they are exceeding the speed limit and should slow down. The VAS is situated approximately 100 metres along the road from the HD ANPR camera. The camera is triggered by Radar which then transmits a wireless signal to the VAS which in turn illuminates the speed roundel and displays the vehicle registration number. The whole system is designed to be quickly installed utilising a cabinet based pole for the camera and a smaller signal pole for the sign. Both parts simply require a mains power supply and ideally located on the footway or similar. The camera and sign are linked by radio transmitter. In addition through the remote 3G communications the council have access to all the data gathered by the system including average speeds, particular vehicle speeds, individual repeat offenders to name but a few.
Suilvision Traffic Calming System
Already installed under the name “SpeedWatcher” in one London Borough the system is having a positive effect. A quote from the Traffic Department Web page: “Signs have no enforcement powers, but can be effective in reducing traffic speeds and the information collected is routinely presented to the Metropolitan Police as part of the intelligence they use to target their enforcement action. The SpeedWatcher equipment takes this concept one stage further. It uses a number plate recognition camera to display the number plate of the offending vehicle. This ‘name and shame' approach has been shown to have a greater effect on motorists to slow down.”
