Method for arranging traffic information detection points in local highway network by utilizing detection device

Abstract

The invention discloses a method for arranging traffic information detection points in a local highway network by utilizing a detection device. The method comprises the following steps: establishing a road network model; taking important intersections and town entrances and exits as nodes, performing the overall dividing for the first time on the road network section, and dividing the related sections for the second time according to the road section administration, especially, administrative division; scoring the importance of the positions of index selected nodes and the quantity of the road sections connected by the nodes; sequencing the nodes according to the importance, and then sequencing the road sections related to the nodes according to the magnitude of weight values; and guaranteeing a video detector existing in the road section connected by each node according to the degree of the node importance in turn. According to the method disclosed by the invention, the space coverage rate of the detection and the representativeness of the survey data are practically increased; the least detection points are utilized to acquire the data capable of reflecting the overall traffic information of the road network, and the construction investment and the later running investment of a dynamic traffic data collecting system are extremely reduced; and the scientific rationality of the arranging method and the arranging scheme can be guaranteed.

Description

technical field [0001] The invention belongs to the technical field of laying out traffic information detection points, and in particular relates to a method for laying out traffic information detection points in a regional road network by using detection equipment. Background technique [0002] At present, my country's highways are dominated by coil detectors. The coils are buried underground and cannot be collected, license plates cannot be recognized, and turning flow information cannot be accurately collected. At present, the methods of traffic information detection point layout mainly include random selection method, main road section selection method, calibration line selection method and traffic flow method. However, these methods are all empirical methods, without scientific demonstration and calculation, because the layout points are incomplete, the information obtained is incomplete, and it is impossible to accurately analyze and consider the weight of all roads.
