Embodiment Construction

[0024] The specific implementation of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0025] A road congestion analysis method based on the status of traffic detection equipment, such as figure 1 shown, including the following steps:

[0026] S1: Configure the traffic detection equipment through the front desk. The configuration mainly includes the Mcmaster algorithm, the slow algorithm, the threshold information of the Shandong Expressway algorithm, the result weight ratio, and the result weight ratio of the improved California algorithm. During configuration, each traffic flow detection device can be flexibly configured according to time period, road section and device type according to different needs. At the same time, an improved California algorithm is generated by combining the traditional California algorithm with the binary search method, which automatically determines the optimal threshold.

Abstract

The invention relates to the technical field of intelligent traffic control, and especially relates to a road congestion analysis method based on the state of traffic flow detection equipment. The method comprises the following steps: 1, respectively configuring the threshold information and result weights of an Mcmaster algorithm, a slow speed algorithm and a Shandong high speed algorithm and the result weight of an improved California algorithm for all vehicle flow detection equipment; 2, obtaining the basic traffic data detected by the vehicle flow detection equipment; 3, respectively employing the improved California algorithm, the Mcmaster algorithm, the slow speed algorithm and the Shandong high speed algorithm to calculate the obtained basic traffic data information, and obtaining the traffic congestion conditions under each algorithm; 4, obtaining the traffic congestion condition of a position where the detection equipment is current located according to the result weight of each algorithm. The method combines the plurality of algorithms to calculate the traffic congestion conditions, and effectively improves the accuracy of an analysis result.

Description

technical field [0001] The invention relates to the technical field of intelligent traffic control, in particular to a road congestion analysis method based on the state of a vehicle flow detection device. Background technique [0002] In the existing technology, there have been many related products for road congestion analysis, but they are basically the direct use of certain traditional algorithms. Some algorithm thresholds are difficult to determine, and artificially set thresholds often have unsatisfactory detection rates and single The utilization of the algorithm has poor adaptability to the road state. Contents of the invention [0003] In order to solve the above problems, the present invention proposes a method of combining multiple algorithms to analyze road congestion; at the same time, for algorithms that are difficult to determine the threshold, such as the California algorithm, an improved California algorithm is proposed, and the threshold is determined aft...
