Passenger information systems

Dynamic passenger information systems (DPISs) provide an overview of the changeable world of public transport. GTI designs, builds and manages systems that use a GPS system or detection loops to compare the actual travel times of buses and trams with their timetables. Any differences are displayed on DPIS boards to keep passengers informed of current departure times.

Overview of public transport dynamics
GTI uses advanced dynamic passenger information systems (DPISs) to provide an overview of the dynamics of public transport. The DPIS uses a GPS system or detection loops in the road to compare the actual travel time of a city bus or tram, for example, with its service timetable. Any differences are communicated to a central computer via substations and are sent from there to displays at stops and stations and in the bus or tram itself.

Always up to date
Dynamic passenger information systems (DPISs) keep passengers up to date with their bus or tram's current arrival and departure times. The systems also ensure the control room receives current information. Our engineers and automation experts work very closely on the development, installation and management of the DPIS. GTI is often the main contractor for the whole project. We also supply the hardware and software and install the fibre-optic infrastructure.
