ASEAG (established as “Aachener und Burtscheider Pferde-Eisenbahn-Gesellschaft“ – Aachen and Burtscheid Horse Railway Company) operates 69 routes covering 2,000 bus stops in Aachen and the surrounding area. As in all major cities, it is not uncommon for services to suffer delays due to heavy traffic or even something as simple as a car parked incorrectly. One challenge facing dispatchers was that the ASEAG buses did not have transmitters reporting the locations of the vehicles and reliably passing their current positions in the city on to the control centre. Furthermore, communication between drivers and the control centre was possible only by means of the interference-prone analogue VDV (Association of German Transport Companies) data and voice radio. Even trees at the side of the road were enough to break the connection.
The primary objective of ASEAG was to replace the outdated radios and install a system that would provide reliable support for communication between drivers and the control centre and transmit position data at frequent intervals. In the course of the conversion to state-of-the-art positioning technology, it was also intended to connect a high-performance passenger information system using displays and a passenger app to keep waiting travellers up to date on departure times and thereby to increase passenger satisfaction in the long term.
"The new displays and our ASEAG mobil app are further elements in a comprehensive passenger information network. Thanks to the transmission of real-time data, our passengers can plan their journeys more precisely and in a manner suited to their own needs."
ASEAG decided to implement additional components of the standard IVU.suite software already in use.
In collaboration with IVU, the outdated VDV data radio was replaced by a GPRS data radio on all 356 buses within just three months. The vehicles report their position to the control centre every twenty seconds. This enables extremely precise positioning, which means that the timetable situation can be calculated accurately. The driver and dispatcher can also contact each other via the company‘s own analogue voice radio. This means that ASEAG is not reliant on public data radio providers and is not affected if they suffer disruptions. This type of mixed radio enables the benefits of GPRS data radio and analogue voice radio to be combined. At the ASEAG control centre, data is collected in the IVU.fleet software component, where it forms the basis for operational control of the vehicle fleet.
The IVU.realtime passenger information system, which is dynamically linked with IVU.fleet, transmits the departure times of the buses in real-time to 65 dynamic passenger information display boards in the area. IVU has also developed the “ASEAG mobil“ passenger app, which likewise accesses real-time data on bus departures. The free app informs passengers not only about when the bus will arrive, but also about where and when passengers need to get off or change to a different bus in order to reach their destinations. For added convenience, the app automatically adapts navigation to the actual traffic situation, issuing visual and audible warnings if a connection cannot be made. It also suggests an alternative route upon request.
Durch die Modernisierung des Funksystems sind die Kommunikation und der Datenaustausch zwischen Fahrern, Fahrzeugen und Leitstelle schneller und effektiver geworden. Die Disponenten in der Leitstelle können die Position der Fahrzeuge jederzeit einsehen und Anschlüsse auch bei Verspätungen sichern. Dank der Echtzeitinformationen erhalten die Fahrgäste aktuelle Abfahrtszeiten direkt über die Anzeiger an den Haltestellen und die App auf ihrem Smartphone. Dieser Service kommt gut an in der StädteRegion Aachen: Der digitale Reisebegleiter wird in den App-Stores mit vier von fünf Sternen bewertet. Der Kommentar eines Nutzers bringt es auf den Punkt: „Ziemlich praktische App. Endlich weiß man, wo der Bus steckt.“
