Abstract:The Enhanced Digital Map Project (EDMap) was a three-year effort launched in April 2001 to develop a range of digital map database enhancements that enable or improve the performance of driver assistance systems currently under development or consideration by U. S. automakers. The project began with identification of safety-related applications, from near-term (within three years after completion of the EDMap project) to long-term (at least ten years after project completion), that would benefit from or be enabled by map database improvements. The map database requirements for each application were determined using feedback from the map database supplier with regard to data collection feasibility and database maintainability. Using the application requirements, the map database supplier constructed map databases for specified test areas, and participating automakers each employed these map databases to develop, demonstrate, and evaluate the performance of selected driver assistance systems. The resulting assessment provides direction to map suppliers in terms of the enhancements needed for future driver assistance systems, and provides a roadmap to the USDOT in terms of safety-focused systems that are enabled by enhanced map databases.
