Abstract

The invention provides a road traffic state identifying method. Each lane of a road is subjected to data acquisition and the traffic state is predicted and judged by using the data average value of each lane. Compared with the prior art, the method has high anti-interference performance, the traffic state is more accurately predicted and judged, and the method is more accordant with the traffic state.

Description

technical field [0001] The invention relates to a road traffic state recognition method, in particular to a road traffic state recognition method for improving the accuracy of judging the traffic state. Background technique [0002] With the rapid development of urban traffic and the rapid increase of vehicles, the contradiction between supply and demand of roads has become increasingly prominent. If it is necessary to provide fast and effective data for induction, it has become the focus of attention. There are more and more types of sensors used to collect road traffic flow, such as loop coil detectors, microwave detectors, etc. Due to the complexity of the road traffic conditions, coupled with the characteristics of the sensor itself, the differences in the set points, and the diversity of uses, the collected data fluctuates greatly, which brings certain difficulties to the identification of road traffic conditions. [0003] At present, the common way to solve the above ...
