Up-to-date map data is a must for current and future in-vehicle ITS applications. Today, digital maps are normally stored on DVDs or hard disks, with periodic updates available only on replacement disks. However, new mechanisms for updating maps have been investigated and should reach the market within a few years. As the real world is changing every day, detecting changes to the road network quickly and at a low cost is a challenge. Although mapmakers continuously survey the European road network for changes, map information is not always up-to-date or accurate.
This is a problem, as navigation and Advanced Driver Assistance System (ADAS) applications are dependent on highly accurate map data. The FeedMAP project will study the commercial and technical feasibility of map deviation feedback using a standardised mechanism for delivering incremental map updates.
In general, mapmakers rely on road authorities and user feedback to detect the latest changes in the road network. In order to improve the flow of map feedback, the FeedMAP concept uses all vehicles equipped with a map as probes to check if the maps are indeed accurate.
In addition, the project is developing a framework that will easily detect map deviations based on information from only a limited number of vehicles and quickly update the maps of all other vehicles. The project’s main focus will be on static and semistatic changes to the maps. In addition, events such as traffic jams or accidents can be added to the maps using a variety of information sources, making them more dynamic.
