The present application provides a system, method and device for judging traffic saturation, which relate to the field of traffic signal light control. The method includes: acquiring vehicle occupancy data within the duration of the red light phase sent by the upstream detector in the lane corresponding to the phase to be measured; According to the comparison result between the occupancy time of the vehicle occupancy data and the preset occupancy time, determine the required traffic volume of the lane corresponding to the phase to be measured; according to the required traffic volume and saturation flow rate of the lane corresponding to the phase to be measured and the timing information of the signal period to which the phase duration of the red light belongs, to determine the traffic saturation corresponding to the phase to be measured. Combined with the lane-point detector of the lane corresponding to the phase to be measured and the signal cycle timing information corresponding to the phase to be measured, the traffic demand of the lane corresponding to the phase to be measured can be accurately measured, and the calculation accuracy of traffic saturation is improved.
Description
technical field [0001] The present application relates to the technical field of traffic control, in particular, to a system, method and device for judging traffic saturation. Background technique [0002] Traffic saturation is one of the important indicators reflecting the level of road service. The higher the value of traffic saturation, the lower the level of road service. Since the road service level and congestion degree are restricted by many factors, it is difficult to consider many factors in practice, so the saturation value is often used as the main index to evaluate the service level. [0003] In the prior art, the method of obtaining traffic saturation is as follows: by laying induction coils at the stop line of road intersections, the number of passing vehicles within a set time period is collected through the induction coils, and the saturation is calculated according to the collected number of vehicles , to obtain the traffic saturation of road intersections....
