Embodiment Construction
[0064] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0065] figure 1 The principle diagram of the real-time traffic jam detection method and system of the expressway provided by the present invention, firstly explain the operation process of the real-time traffic jam detection method and system of the expressway provided by the present invention.
[0066] see figure 1 , each expressway has a plurality of monitoring checkpoints, the present invention first uses the monitoring checkpoints as nodes to divide the expressway into intervals, every two adjacent monitoring checkpoints are an interval, and each interval is divided by a certain length For mu...

The present invention relates to an expressway real-time traffic jam road condition detection method. The method comprises: dividing an expressway into a plurality of section through taking monitoring bayonets as nodes; calculating a first average stroke speed corresponding to each section; determining the traffic condition grade of each section according to the first average stroke speed; and publishing the traffic condition grade of each section in real time. In the daily travelling, travelling people can obtain the traffic jam condition of the expressway where the travelling people are about to drive along at a certain time quantum in real time through modes such as an APP, a special website, a short message or a phone call, the expressway real-time traffic jam road condition detection method is convenient an rapid, and high in information timeliness and high in accuracy, and the travelling people can select reasonable travelling time, mode and lines according to the obtained information so as to effectively regulate and control the traffic traveling requirement and relieve the road traffic pressure. The present invention further provides an expressway real-time traffic jam road condition detection system.
Description
technical field [0001] The invention relates to a traffic jam detection method, in particular to an expressway real-time traffic jam detection method and system. Background technique [0002] Today, although the scale of road construction continues to expand, it is difficult to meet the rapidly growing motorized traffic demand. According to statistics, the growth rate of the number of motor vehicles is 2 to 3 times the growth rate of roads. For cities, the growth of roads is far from meeting the traffic needs of residents. The urban area spreads to the periphery, the traffic congestion period is prolonged, and the average vehicle speed decreases year by year. The ensuing traffic environment, traffic safety, parking shortage and other problems are becoming more and more serious. Therefore, improving and managing urban traffic congestion is the key to building intelligent transportation. The primary task. [0003] At present, there is no relevant system in the traffic system...
