Weigh In Motion system enables re-opening of the Newcastle High Level Bridge.
Background
The Grade 1 listed bridge, built by Robert Stephenson in 1849, was shut to traffic in March 2005 for safety work which uncovered that major repairs were needed to the historic structure. With £40m of work by Network Rail complete, the bridge required restrictions on traffic levels and vehicle weights to be put in place in order to reopen.
In order for Rail Track to protect public safety and its investment in the bridge they insisted that road traffic would only be allowed back on to the bridge if it was protected by an electronic system to ensure crossings only by authorised traffic.
Clearview Intelligence devised and supplied a system with WIM linked to ANPR cameras (PIPS) so that all vehicles crossing the bridge are weighed and their number plates compared with a 'white list' which stores the details of all buses and taxis authorised to use it.
A photograph of the vehicle, along with it's number plate, weight and speed is recorded and the council is alerted if any vehicle crosses that doesn't fit within the parameters of the regulations. For example if its not on the 'white list', if any vehicle exceeds the 20mph limit or if any vehicle over the 3.5 tonne weight limit and is not on the bus 'white list'.
On site installation commenced in May 2008 and was fully tested and commissioned within five days. Tyneside's iconic High Level Bridge was finally reopened in June 2008 to Gateshead-bound
public transport.
