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.
