The Development of a Map-Based Driver Assistant Under the Vehicle Infrastructure Integration Framework

Vehicle infrastructure integration (VII) can enhance road safety, mobility and efficiency. By integrating automotive sensor and telecommunication technology, vehicles can acquire high temporal- and spatial-resolution information associated with roadway and environmental conditions through vehicle-to-vehicle (V-V) and vehicle-to-infrastructure (V-I) communications, e.g. dedicated short-range communication (DSRC). A wide range of vehicle safety and non-safety applications can be developed or enhanced by VII. The map-based driver assistance systems such as navigation and speed warning systems are such applications that can benefit from VII. This paper presents a Curve Overspeed Warning system developed by California PATH in the VII- California research project. This system utilizes the on-board digital map and enhanced map data transmitted from the road side equipment (RSE) to predict an upcoming curve and provide warnings to the driver if the speed is unsafe for this curve. A system overview and descriptions of the functional components are provided along with experimental results to show how the map-based driver assistant can improve driver’s safety through VII. In addition, technical issues associated with map update by integration of VII-enabled data are discussed.
