Method and device for classifying traffic zone

Abstract

The invention discloses a method and a device for classifying a traffic zone, which relates to the traffic information field, and is characterized in that a classified traffic zone can accurately reflect the intrinsic traffic characteristics in real time. A scheme is as follow: a zone to be classified is gridded according to a real road network; communication record quantity of each base station in each grid is acquired within a first preset time period, and a quantity discrete value corresponding to each base station is obtained; sum-and-square difference comparison is conducted for the quantity discrete value of each base station and a preset group of characteristic curves, and a minimal error characteristic curve with the minimal sum-and-square difference of the quantity discrete value of each base station is selected; the corresponding base station with the same minimal error characteristic curve is classified into the same base station type; the quantity ratio of base stations of the same base station type is calculated in each grid; the type of the grid is determined according to the base station type with the maximal quantity ratio of the base stations in the grid; and the adjacent grids with the same grid type are merged to form a traffic zone. The method and the device are used for classifying the traffic zone.

Description

technical field [0001] The invention relates to the field of traffic information, in particular to a method and device for dividing traffic areas. Background technique [0002] Before the urban traffic management system implements traffic control and construction, it needs to analyze the traffic situation in the urban area to ensure the rationality of the control and construction measures. In recent years, the scope of cities has continued to expand, and the urban traffic situation has become increasingly complex. The entire urban area is divided into multiple traffic districts to reduce the complexity of the analysis objects of the urban traffic management system and facilitate the traffic control and construction of the urban traffic management system. Traffic area refers to a collection of nodes and links with a certain degree of traffic correlation and traffic similarity, which changes with time, correlation and similarity, reflecting the spatiotemporal characteristics o...

Problems solved by technology

[0005] The urban traffic system is a dynamic system with stochastic characteristics. The traffic districts divided according to the geographical location of the urban area, road traffic flow information and the actual road network separation lack the research on the dynamic information of the roads in the urban area and the internal traffic characteristics between the areas. , resulting in the traffic area not being able to reflect the intrinsic traffic characteristics in real time and accurately
