Participating in field tests for Driving Safety Support Systems
In February of 2009, Omron took part in large-scale demonstration tests of Driving Safety Support Systems (DSSS), which were performed in the Rinkai Fukutoshin (new Tokyo waterfront subcenter) area. This field experiment was sponsored by the Universal Traffic Management Society of Japan. DSSS is a system designed to transmit information from various roadside sensors to in-vehicle units via wireless vehicle-to-infrastructure communications technology.In-vehicle units alert drivers to the potential for traffic accidents.
Conventional road traffic sensors usually target four-wheeled vehicles. However, accidents involving pedestrians or bicycles/motorcycles in fact account for a significant percentage of traffic accidents. Omron developed pedestrian and bicycle sensors employing a space-time MRF (Markov Random Field) technology developed jointly with the University of Tokyo’ s Institute of Industrial Science. In the experiment, these sensors were deployed in a support system that detects pedestrians crossing the road and alerts the driver, and a system which protects bicycles/motorcycles when cars are making left turns. The effectiveness of these newly developed systems was verified through recent field tests. Omron plans to continue participating in fields tests so as to accelerate practical use of systems that can contribute to reduced traffic accidents
