Abstract

The invention discloses a urban traffic control area division method and device. The method comprises the following steps: acquiring region characteristic data, and performing gridding on the data toobtain first characteristic data, analyzing the first characteristic data to obtain a space distribution density of the urban traffic, and determining a Thiessen polygon network of the urban traffic according to road network space data; and performing data stacking on the space distribution density of the urban traffic and the Thiessen polygon network so as to determine the boundary of each control area of the urban traffic. The used regional characteristic data is suitable for multiple data sources capable of representing the region traffic characteristics, the Thiessen polygon network obtained through the space distribution density and the road network space data can efficiently and accurately detect and understand the urban space, thereby quickly and effectively performing space slicingon the city on finer space resolution and obtaining an appropriate urban traffic control area.

Description

technical field

[0001] The embodiments of the present invention relate to the technical field of transportation, and in particular to a method and device for dividing urban traffic control areas. Background technique

[0002] With the continuous expansion of the city scale, traffic problems gradually show regional characteristics, and city managers began to control traffic problems by dividing control areas. The regional signal control scheme needs to be formulated according to the traffic operation status of different regions. Reasonable division of urban traffic control areas is the premise of regional signal control.

[0003] At present, most cities use administrative regions or jurisdictional areas as traffic control areas. The control area is relatively wide, and the characteristics of the area and traffic operation status are diverse. It is impossible to formulate a macro signal control strategy to solve the traffic problems in the area. Contents of the invention ...
