Designed to support drivers at every turn.
Explore the solutionWhen situations change quickly, drivers need to stay in control. Real-time communication and built-in safety features help them respond faster and keep services moving. With Trapeze, operators can support drivers on the road and deliver a safer, more reliable bus service.
Each bus continuously sends its location, speed and progress back to the system. This gives a live view of where every bus is and how it is performing across the network.
The system tracks how far each bus has travelled along its route and how much distance remains. This is used to calculate how long it will take to reach upcoming stops.
Past journey data is used to understand how long different parts of a route typically take, including peak periods, quieter times and seasonal changes.
Arrival times are calculated using a combination of live vehicle data, recent journey conditions, historical patterns and timetable data. These inputs are continuously balanced to maintain accuracy as conditions change.
Traffic conditions, incidents and roadworks can be fed into the system to adjust predictions in real time, helping reflect delays as they happen.
As buses move, arrival times are constantly recalculated and updated across all passenger information channels, ensuring the latest information is always shown.

Trapeze connects drivers with the information and support they need on the road, linking what’s happening on the bus with your control centre.
Automated support cuts down manual updates, so drivers can focus on driving safely.
Drivers follow clear schedules and routes, avoiding missed turns and keeping services on time.
Drivers message or speak to control as situations change.
Drivers trigger an alert that opens a live channel to control, so teams can hear what’s happening and respond straight away. Add teams after control is control teams.
Passengers see live updates that reflect what’s actually happening on the road.
Announcements and displays keep passengers informed at every stop and along the route.
Passengers make connections using up-to-date information, without guesswork.
Passengers know what’s going on and feel confident using your buses.
Control teams see how services are running and spot issues as they happen.
Faster responses mean fewer delays and more buses running on schedule.
Teams use live data from each bus to decide when to intervene or adjust services.
Better service leads to more satisfied passengers and more people using your buses.


A single screen in the bus shows routes, timing, next stops and messages from the control centre. So drivers see how they’re running against the timetable in one place.
Screens and audio on the bus share next stops, route updates and journey information as the service runs.
Drivers and control can message or speak directly, so delays, incidents and route changes are handled as they happen.
Stops are announced automatically based on the bus location, without the driver needing to do anything.
Each bus sends its location to the control centre, so teams can track it against the timetable.
Sensors track how many passengers board through each door, so operators can see when buses are full or overloaded and spot fare evasion.

Hochbahn wishes to noticeably improve the quality of local public transport for customers by means of drastically improved passenger information and sustained transfer protection. The positive reactions of passengers show that we're on the right track.
