Intelligent Transport System (ITS)


ITS  (Intelligent Transport Systems)will reduce traffic accidents and congestion byreceiving and transmitting information on humans,roads, and automobilesthrough the use of telecommunication technologies. Since 1991, Mazda has been proactively supporting the ITS project as an automotive manufacturer,and working collaboratively with the government, local communities, and related companies in order to realize a society where the road traffic is safe and accident-free.

Technology to notify the driver of invisible danger

Mazda is actively promoting the research and development of practical application of ITS in order to expand the area to detect dangers beyond wherei-ACTIVSENSE, Mazda's advanced safety technology, can reach today. The new system using ITS technology is positioned as a way to enable drivers to recognize (see, hear or otherwise sense) a threat in 360degreesincludingblind angles at crossroads or at a distance beyond the reach of camera or radar.

Mazda Atenza ASV-5 - Advanced Safety Vehicle

Hazard recognition support with an intuitive Human Machine Interface (HMI) thanks to a combination of communication technologies and sensors

-The vehicle eliminates blind-spots and supports hazard recognition in360-degrees through a combination of vehicle-to-vehicle, street-to-vehicle and pedestrian-to-vehicle communication technologies and onboardautonomous sensors.

-The intuitive HMI displays hazards surrounding the driver in all directions including blind spots, and does notinterferewith the operation of the vehicle.

Head-up display

-When the driver fails to recognize a hazard, and a risk of collision arises, the HMI warns the driver to brake.

esting the world's first advanced safety vehiclecapable of streetcar-to-vehicle communication on the streets of Hiroshima (2013)


As part of post-congress tour for the ITS World Congress Tokyo 2013, a research unit composed of the University of Tokyo, Mazda Motor Corporation, Hiroshima Electric Railway co., Ltd. and National Traffic Safety and Environment Laboratory conducted the world's first test on public roads of a safety system combining streetcar-to-vehicle communication devices and in-vehicle autonomous safety technologies.Used by approximately 150,000 people daily, streetcars form an essential component of Hiroshima's public transportation system. The system exchanges information between automobiles and streetcars when the two get close to each other, and the trial verified its effectiveness inpreventingcollisionsin situations such as when a vehicle turns right or enters the streetcar's path in order to pass a stopped vehicle. The trial also verified the effectiveness of preventing accidents bycoordinating with asmartphone application for the early detection of pedestrians who in positions difficult for the driver to see.
