The horizontal PReVENT subproject MAPS&ADAS develops a map based Driver Warning System, consisting of an ADAS map, the Speed Limit Warning and the Hot
Spot Warning Application. This application warns the driver in case he is approaching a certain location in the street network in a manner which has a potentially high risk of an accident in the next seconds. The hot spots are generated offline beforehand using e. g. police reports of accidents and put into the ADAS map. During the drive the data is communicated from the ADAS map to the Warning Application via the ADAS-Interface. The Hot Spot Warning application compares the attributes of the hot spots with the variables of the current ride, like location, speed, time of day, weather, moisture and lighting conditions and calculates in a 1 Hz frequency the risk. If certain values are reached, a warning to the driver is issued. This application will be technically validated and the safety effects will be assessed, using the recently developed and validated power model to estimate the change in traffic safety.
