DEMONSTRATION TEST FOR SIGNAL INFORMATION PROVISION SYSTEM IN DSSS BY UTMS

摘要

The "Driving Safety Support System" (DSSS) coordinates the advanced functions of traffic control infrastructure and the intelligent functions on vehicles themselves in order to improve safety for vehicle traffic and decrease traffic accidents. We think that a signal information provision system in DSSS is effective to avoid a head-on collision in a signal intersection. By this system, the infrared beacon which has enough actual results provides vehicles with information such as signaling information or road alignment information. Vehicles judge dangerous situations from this information and self-vehicle position, velocity or brake information, and risk aversion works by notifying the driver of care information. In this judgment, self-vehicle position which is distanced from an intersection (stop line) is important information. We adopted a method to sense the precise location of vehicles from communication establishment timing of an infrared beacon and an in-vehicle unit and planned the demonstration test which collected foundation data of the detection accuracy. By this report, we describe the demonstration test aimed for verification of the positioning accuracy.
