Embodiment Construction
[0020] The invention discloses a method for extracting traffic characteristic parameters based on vehicle-mounted Bluetooth, which specifically includes: a traffic parameter extraction algorithm based on vehicle-mounted Bluetooth, processing traffic data of vehicles detected by Bluetooth detection equipment, and extracting vehicle types, road section traffic, Traffic guidance and control parameters such as average vehicle speed and travel time. The traffic data of vehicles includes dynamic parameters such as average speed, vehicle density, traffic volume, peak hour coefficient and so on when vehicles pass through the intersection.
[0021] Those skilled in the art know that as long as the average speed of the vehicle passing through the road section is detected, and the average speed is compared with the free flow speed of the road section, the traffic state of the road section can be easily judged, that is, whether it is in Congested state.
[0022] The following details how...
