The system was designed in order to calculate the numbers of people waiting on train platforms, so as to more efficiently schedule the trains. The system controls two variables, the number of trains in operation and the dwell time at the station (as the trains run at a constant speed this sets the frequency of operation). It works by counting the numbers of passengers entering and leaving the platform area. The system uses the PEDMON product, which is concerned with PEDestrian MONitoring in public places. The development of the product involved the development and testing of methods of counting people moving through selected areas of interest, with special emphasis on the ability to deal with wide doorways and monitoring people moving in both directions (in and out) simultaneously. Typically, the locations to be monitored could be at external entrances and exits, internal doorways and passageways, or any position where the sensors could be installed. The system has been installed for 3 years and paid back in less than 6 months. The system has now been extended to control a second train system, with control for both systems centralized at one point. The system cost approximately 30,000 pounds, and saves the operator 120,000 pounds per annum.
