Nissan test advanced road traffic system aimed at reducing accidents and easing congestion

September 18, 2006 Nissan is set to begin testing an intelligent transportation system in Japan that allows vehicle-to-infrastructure communication to help reduce traffic accidents and ease congestion. The system uses information obtained from nearby vehicles and roadside optical beacons to wirelessly alert drivers to potential danger from approaching vehicles. It also provides drivers with fastest-route information with Nissan’s probe server collecting city –wide traffic data from the mobile phones of Nissan’s CARWINGS navigation service subscribers, taxi services, and vehicle data collected by mobile phone operator NTT DoCoMo. This information is then sent to the driver’s navigation screen where it is displayed as real-time maps showing the traffic flow and density. Screen shots and diagrams here.
