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.

    Expansion of ITS systems has accelerated in Qatar this year, with rapid deployment of a traffic control system in Doha. Less than 10 years from now an extensive system of ITS technology will be operating in Qatar, informing and directing users of the country’s roads. That can be stated with confidence for a number of reasons: the world’s richest country per capita will host the World Cup in 2022 and is understood to be planning to develop sophisticated systems of ITS for road safety and traffic managemen

    The German Aerospace Centre DLR has arrived at the 2012 ITS World Congress with a unique system for rail safety – for preventing collisions between trains and improving safety for track workers. Whereas conventional train collision avoidance systems involve networks of base stations, DLR’s Railway Collision Avoidance System (RCAS) uses direct communication between trains or hand held devices without expensive infrastructure and so with substantial reduction in cost. “RCAS communication is via the Tetra stan

  • Car parking and parked cars need not be a technological black hole
    March 19, 2015
    David Crawford mines the potential of joined-up parking. Drivers conventionally see parking as an isolated, often frustrating, action; but collectively their attempts to find a space impact hugely on traffic flows. But new analyses of parking events look set to deliver real benefits to motorists and cities alike. Initiatives getting under way around the world are highlighting the advantages of connecting up parking events and – eventually - parked cars. The hoped-for results include not only enhanced urban
