A method and system for issuing urban road network guidance schemes based on travel structure

Abstract

The invention discloses a method and system for releasing an urban road network inducement scheme based on a travel structure. The system includes a data access module, a demand structure analysis module, an inducement route search module, an inducement strategy generation module, and an inducement release module; The access module obtains the vehicle checkpoint passing record of the entire road network within a specified time period, and obtains the travel structure of the motor vehicle from the checkpoint passing record; then constructs the road network topology according to the travel structure, and obtains the OD point pairs of the road network Then obtain the real-time traffic flow data of the travel route set, and generate a set of congested road sections based on the traffic flow data; at the same time, build an induced path search model based on the set of congested road sections, and based on the traffic operation conditions and history of the road network The traffic trajectory generates multiple guidance paths for each OD point pair; finally, the optimal guidance release strategy and the suboptimal guidance release strategy are determined according to the travel of the motor vehicle; the invention can improve the traffic efficiency of the road network.

Description

technical field [0001] The invention belongs to the technical field of urban road network traffic operation induction release, and in particular relates to a method and system for issuing an urban road network induction scheme based on travel structure. Background technique [0002] In the urban road network, traffic guidance release is one of the indispensable means of modern intelligent traffic operation management. It mainly provides urban road network traffic guidance information or instructions for road vehicles. Reasonable distribution of demand in the road network is the goal, so as to achieve the purpose of alleviating traffic congestion and facilitating motor vehicle travel; however, based on the unpredictability and randomness of traffic operation data, it may lead to the problem of poor traffic guidance release, especially in real-time Traffic flow changes, so a real-time and effective traffic guidance release method and a corresponding guidance release generation...
