Budapest – Bosch's new collision warning technology, which has already been proven abroad and in Debrecen, has been installed for testing purposes on two of BKV’s (Budapesti Közlekedési Vállalat, the public transport company of Budapest) Tatra trams, which work mainly on line 41, and will contribute to even safer transport. In the capital's traffic, collisions can easily occur with significant material damage or even bodily harm. Bosch's innovative collision warning system alerts tram drivers in case of danger, allowing them to apply the brakes seconds earlier and avoid minor collisions and accidents.
"This technology is truly invented for life, true to the Bosch slogan, and is an effective way to help tram drivers do their tiring work, which requires a high level of concentration. Examples from abroad show that it can halve the number of accidents involving trams. The technology not only saves lives, it also saves significant costs for operators and helps ensure reliable, on-schedule operations," said Zoltán Szőke, vice president engineering automated driving in Hungary at Bosch.
Commenting on the collision warning system testing, Péter Borbás, BKV's tram operations director, stressed that BKV is constantly striving to make the capital's transport, including public transport, as safe as possible. "As the largest public transport operator in Budapest, our commitment and involvement is to consider any technology that can help BKV achieve this goal. BKV has always supported methods that promote accident-free transport, so our participation in the current project – by providing the tram and the test environment in the capital – was not in question."
The technology, which is tailored to the trams, was developed jointly by engineers from the Bosch Engineering Center Budapest and Bosch Engineering GmbH, and the camera on which the system is based, as well as the radar sensor, is manufactured at the group's site in Hatvan. The technology consists of a multifunction camera, a radar sensor and a control unit. The special data camera provides an accurate picture of traffic conditions and tracks and predicts movements, while the radar sensor continuously monitors the track and detects anything that might cross the tram's path.
Tailoring the technology to the tram line
The collision warning system is being individually calibrated and trained for the traffic environment of Budapest's trams. In the commissioning phase, the tram equipped with sensors and cameras has been driven thousands of test kilometers in both inner-city and suburban environments to fine-tune the system.
The collision warning system mounted on a pair of Tatra trams in Budapest has already warned more than ten times on its first trip, but during the last three months of testing, nearly 1,000 warnings have been recorded over a distance of almost 12,000 kilometers. In more than 500 situations, the system has helped to reduce the risks in everyday driving by raising drivers' awareness and thus preventing potential accidents.
