Abstract

The invention relates to a method for constructing and solving a route model of a directed graph of a traffic road network based on a steering relationship. The invention fills up the technical blank of the directional path road network model required for urban traffic signal control. The spatial logical topology relationship proposed by the present invention is closer to reality than the existing methods, and provides the core technology for dedicated control road network construction for road network level and lane level traffic signal control, and can be directly used for SCATS signal control scheme optimization and performance evaluation , It plays an important role in improving the level of urban traffic management, reducing traffic congestion, and optimizing the traffic travel environment.

Description

technical field [0001] The invention relates to a method for constructing and solving a lane-level traffic road network directed graph path model based on a steering relationship, and belongs to the technical field of urban road traffic signal control theory and application. Background technique [0002] With the continuous development of urban transportation information infrastructure and intelligent transportation system construction, a large amount of traffic information data has been rapidly accumulated, which can provide strong support for macro-traffic policy formulation, transportation industry management, and traffic information services. At present, the common sources of road traffic information are coil data, GPS data, vehicle license data, mobile phone data, etc. However, taking Shanghai and other cities as an example, the road traffic signal control SCATS system owned by more than 30 domestic cities, in addition to playing the main role of traffic signal control,...
