Method and device for judging release of traffic incident

The embodiment of the invention discloses a method and device for judging release of a traffic incident, relating to the field of intelligent traffic systems. Whether the traffic incident is released is automatically judged according to a quantized specific value obtained according to floating car data, and subjective deviation caused in a manual judgment process is avoided, thus the accuracy of judging the release of the traffic incident is improved. The method provided by the invention comprises the steps of: obtaining the floating car data in an area where a road link generating the traffic incident occurs; obtaining a speed of the road link according to the floating car data, wherein the speed of the road link is a traffic flow speed on a road corresponding to the road link; and judging wherein the traffic incident is released or not according to the speed of the road link. The invention is suitable for judging the release of the traffic incident.
