Toll Bridge Auditing System.

This system monitors signals from two buried inductive loops to maintain a real time tally of vehicles using a toll bridge. It is a small desktop system ( the toll booth is tiny!) and displays a running total of the vehicles on both carriageways during a shift. The system also collates the data by the hour, shift, day, week & month. A small printer is used to print a variety of reports. As well as the main function of auditing the toll takings, it also provides management with information on when it would be cost-effective to adjust the periods when the toll booth is staffed; during quiet periods the takings would not cover the wages. A first system was installed in 1988 and subsequently replaced with an updated version (shown above), with extra facilities, in 2003.
