Description:

Connection PIDs are intended to inform passengers about events associated with the operation of public transport, like bus schedule, bus stops and possibility to change to other lines. Passenger information system for bus stations mainly rely on constant communication between:

1. Buses equipped with GPS (Global Positioning System)

2. Displays at stops, bus stations and tram loops

3. Central computer system

Data on the position of the vehicle is transferred to the main computer, which then estimates the arrival time at each stop on the route and then sends this information to the displays at bus stops. The signal from GPS transmitters installed in vehicles is sent via GPRS to a server that compares the real location with the planned location of the vehicle-in line with the schedule. If discrepancies occur system continuously sends information via the Internet to the computers controlling the boards at bus stops. In this way, information for passengers waiting at bus stops is always current. Inside the vehicle system modifies the arrival time at next stops based on data from the GPS.
