Abstract: A method is disclosed, comprising holding available, by at least a first apparatus, data associated with each road segment of at least one road segment, said data comprising (i) a representative of a first metric associated with spatial properties associated with the respective road segment; (ii) at least one representative of a second metric associated with at least one dynamic event associated with the respective road segment; and (iii) at least one representative of a third metric associated with a speed associated with the respective road segment, and wherein the method comprises, for at least one road segment of the at least one road segment, providing, by said at least one first apparatus, a safety data of the respective road segment at least partially based on the representative of the first metric, the at least one representative of the second metric and the at least one representative of the third metric associated with the respective road segment.

Abstract: A method for providing alerts for a traffic slowdown includes receiving location data for at least a first vehicle of a plurality of vehicles, map matching the location data for at least the first vehicle to a road network, calculating an approaching speed for at least the first vehicle at a first time, calculating a final speed for at least the first vehicle at a second time, and generating a traffic slowdown message in response to the approaching speed and the final speed. The traffic slowdown message includes at least one characteristic of the traffic slowdown.
