Automatic Passenger Counting Efficient Collection of Ridership and On-Time Performance Data Vehicle System 2.1.2 The Analyzer Unit From the signals transmitted by the sensor(s), the analyzer determines the number of persons getting on and off the vehicle. These counts are interrogated and stored by the on-board computer. The data are transmitted from the analyzer to the on-board computer via dedicated data cable. 2.2 GPS Receiver A GPS receiver is providing every 4 seconds the vehicle position. 2.3 On-Board Computer COPILOTsmart with Integrated WLAN The core unit of INIT’s on-board APC equipment is the COPILOTsmart computer and acting as the interface to both the vehicle electronics such as Automatic Passenger Counting system and the vehicle location component such as GPS. With the integrated WLAN card it is utilized as the link between the APC equipment and the post-processing system. 2.4 Required Signals • No Motion Signal (LRV) • Odometer (Bus) • Door Open Sensor • Ignition • Battery Power 2.5 Network Overview The Access point is installed at the garage. As soon as the vehicle arrives in the range of the access point the data is transmitted to the Wlan Garage server. The FTP client on the central server retrieves the data from the garage server and the data is matched with the schedule information once a day. The matched APC information is exported into MOBILEstatatistics and available for reporting. All reports can be accessed through the Oracle data base.

Automatic Passenger Counting Efficient Collection of Ridership and On-Time Performance Data Vehicle System 2.6 Standard Data Receiving Unit: WLANstation (Garage server) Additionally to the wireless LAN clients (COPILOTsmart) in the vehicles, some infrastructure is needed for the WLAN network on stationary side. To build a wireless network, garage stations called access points (AP) are used. Every AP has a maximum communication range of 500 feet. Also, one wireless LAN server (PC) is needed on the garage location. The PC is the main communication partner of the COPILOTsmart. The access point is connected to the Server (WLANstation) through the Ethernet network. The WLANstation server contains two network cards in order to separate the APC network from the company network. 2.7 Data Security Overall, wireless connections are always susceptible to allowing open access unless a protection structure has been integrated into the system. Every 802.11b compliant client adapter may log into a wireless system and transfer data. The best way to counteract the possibility of external users is by means of a customary protection based on a Cisco platform. INIT has done extensive research and has comprehensive experience in locating the safest and most reliable system available.
