Urban road network induction scheme issuing method and system based on trip structure

Abstract

The invention discloses an urban road network induction scheme issuing method and system based on a trip structure. The system comprises a data access module, a demand structure analysis module, an induction path searching module, an induction strategy generation module and an induction issuing module; and the method comprises the following steps: firstly, acquiring whole road network motor vehicle gate vehicle-passing records in designated time through the data access module, and acquiring the trip structure of a motor vehicle based on the gate vehicle-passing records; subsequently, buildinga road network topological structure according to the trip structure to acquire OD (Outside Diameter) dotted pair sets of the road network and corresponding trip path sets; then acquiring real-time traffic flow data of the trip path sets, and generating congestion road section sets based on the traffic flow data; simultaneously, building an induction path searching model based on the congestion road section sets, and generating multiple induction paths for each OD dotted pair based on traffic operation situations and historical passage tracks of the road network; and finally, determining an optimal induction issuing strategy and a sub-optimal induction issuing strategy according to the trip of the motor vehicle. According to the urban road network induction scheme issuing method and systembased on the trip structure disclosed by the invention, the road network passage efficiency can be promoted.

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...
