Automatic Passenger Counting (APC) System is Installed and Functioning
The Automatic Passenger Counting (APC) system was installed to 6 TAK buses and 6 TTTK trolley-buses by October 19, 2006 and has been functioning successfully. The installation of the APC system supports measure’s 12.5 evaluation process.
The APC system, consists of infrared sensors placed in the upper panels of the vehicle doors, board computers (data loggers) sensor, GPS receivers, gateways and radio modems. These are installed on 6 TAK (Tallinn Bus Company) buses and 6 TTTK (Tallinn Tram and Trolley-Bus Company) trolley-buses. A receiver modem connected to a PC is placed in garages. The measured data is transferred to FTP server. Sensors mounted on doors switch on the registration of vehicle coordinates by GPS and passengers are counted by infrared sensors. On buses with four doors the gateway transfers the measured data from both data loggers by modem to PC.APC system is installed by the company RTT AS, with whom Tallinn Transport Department has had few years experience of working together. The number of passengers are accounted for on lines and routes which will be equipped with the public transport priority system before and after installing the system. Reduction in travel time for one passenger will be calculated “before” and “after”. The reduction of travelling time presents the effect stemming from the use of the priority system. This method to estimate the effect of priority system is innovative in Tallinn.
