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.

    AAdvances in LiDAR are helping transport authorities improve services and identify potential problem areas, as geospatial technology expert Dr Neil Slatcher explains. The effects of climate change on the transport infrastructure have long been a cause of concern within the transportation sector - and not only on the structures themselves but also on the surrounding areas. This year, those concerns have become reality with landslides, structural collapses and surfacing issues impacting services across the wo

It was in 2008 that Volvo announced a unique goal in stating that ‘By 2020, nobody shall be seriously injured or killed in a new Volvo'. To contribute towards that aim, it has fitted technology including pedestrian detection, city safety and the

    The growing popularity of hybrids and electric vehicles gives rise to new safety issues in urban environments, as many of the aural cues associated with engine noise can be missing. The solution is to intelligently make vehicles noisier. The rise in popularity of hybrids and Electric Vehicles (EVs) is a result of environmental pressures, shifts in taxation and emerging technologies for batteries and motors. Competition among the car manufacturers means these vehicles need to be cost effective to buy and ope

    An innovative cycle safety device designed to alert truck drivers to the presence of a cyclist is about to be launched. The Cycle Alert system not only alerts drivers to a potential risk in areas frequented by cyclists, it also facilitates a direct warning from a cyclist straight to the vehicle driver. The system has three elements: a unit that is fitted to the bicycle, or worn by a cyclist on their person or helmet, sensors that are fitted to the HGV and a cab-mounted device to alert the driver. The three
