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 increasing availability and accuracy of global navigation satellite system (GNSS) is opening up low-cost options in many areas as David Crawford finds out. Boosting commercialisation of European global navigation satellite system (EGNSS) technologies for ITS initially depends heavily on demonstrating competitive and cost/benefit advantages obtainable from the deployment of EGNOS (the current European Geostationary Navigation Overlay Service), and ultimately the EU’s Galileo constellation (see box). So,

    A431 temporary toll road opens
    A temporary toll road linking Kelston with Bath in Somerset, UK, has opened. Local businessman Mike Watts set up Kelston toll Road Limited to build the 400 metre road, enabling traffic to negotiate the A431 Kelston Road, which has been closed since February because of a landslide. It has cost Kelston Toll Road £150,000 to build the road and Mr Watts estimates it will cost another £150,000 to run the toll road for five months. He plans to charge motorists £2 each way to use the road, which will need to attra

David Crawford assesses a selection of safety initiatives exhibited in Orlando. Vital roles for ITS applications in road traffic safety emerge clearly from a new report from the US Transportation Safety Advancement Group. The report has been carried out for the Next Generation 911 What's Next Forum, which is preparing the way for future development of the US national 911 emergency single call
