Mazda develops system to avoid car-streetcar collisions

The University of Tokyo and Mazda Motor Corporation have jointly developed a system involving wireless communications technology to prevent collisions between cars and streetcars (or trams). The system’s car-mounted sensors can detect signals from a streetcar up to 100 metres away, in contrast with the current range of just a few dozen metres for conventional sensors on cars. The new system is designed to prevent collisions between vehicles and oncoming streetcars by allowing their position and direction

The 5315 University of Tokyo and 1844 Mazda Motor Corporation have jointly developed a system involving wireless communications technology to prevent collisions between cars and streetcars (or trams).

The system’s car-mounted sensors can detect signals from a streetcar up to 100 metres away, in contrast with the current range of just a few dozen metres for conventional sensors on cars. The new system is designed to prevent collisions between vehicles and oncoming streetcars by allowing their position and direction to be automatically monitored, according to the university.

The experimental ASV-5 version of Mazda’s Atenza sedan will be deployed for trials in Hiroshima. Streetcars, which are used by around 150,000 people per day in Hiroshima, form an essential part of the city’s public transportation system.

    The safety of workers during road closures and working alongside, or above, live lanes is becoming an automated process. Ten workers suffered major injuries while working on or near motorways and major A roads in England in 2013, and between 2009 and 2013 eight had been killed. It was against that background that the first commercial application Safelane, the automated traffic management system designed to detect work zone incursions, was carried out during the temporary closure of a motorway.
