Public Transport and the Future

Clean, safe and reliable – this is how mobility of the future must be. Local public transport (ÖPNV) is considered “the” alternative for environmentally friendly transport. Buses and trains are an indispensable part of our mobility and everyday culture and contribute significantly to the quality of life in cities. However, the role of public transport in environmental protection is at least as important. These are all aspects that justify the intensive technological change currently taking place in public transport.

What Role Does Technology Play in Public Transport?

During their daily journey on public transport, passengers on buses, underground trains and trams interact with different systems. Starting with an up-to-the-minute timetable on the mobile phone, the line display, the ticket vending machine or contactless validator, through to on-screen displays and stop announcements. But how are these systems coordinated so that passengers can experience a smooth and worry-free journey? In other words: How do these systems exchange data with each other and what is the technology behind it?


Network Infrastructure is in Demand

Ethernet technology is making its way into public transport systems. Ethernet-based network solutions are favoured, especially in buses, trams and underground trains. Almost all vehicles have a router with a wireless connection to the central control centre. This is where all the data about the entire urban transport system converges. In the control centre, this data is synchronised, updated and passed on to the passengers via displays in the vehicles. The basic prerequisite for this is the networking of all systems in the vehicles.

In local public transport, various participants must be integrated into a higher-level network. These can be cameras for monitoring in the passenger compartment or passenger information and counting systems. Furthermore, video recorders, the central vehicle control, routers and the payment system are typical participants in buses.



It is not uncommon for more than 20 devices in buses to have to be networked with each other. This is done with the help of Ethernet switches especially developed for public transport vehicles. They are used as a data switch and have different properties depending on the requirements and application. With the Ethernet switch product family “ROQSTAR”, we rely on modern and open technologies and standards in public transport.
