Abstract

The present invention provides a travel vehicle route selection method based on historical behavior portraits, which is used for the travel vehicle route selection problem in the prior art. The route selection method for travel vehicles based on historical behavior portraits establishes vehicle portraits based on the traffic characteristics of vehicles in historical traffic data, constructs a time and cost traffic model, and travel vehicles use the constructed traffic model to select routes. The present invention is based on the vehicle route selection method of historical behavior portraits, fully extracts the vehicle travel characteristics of historical traffic data, finds out the optimal cost route selection method that is closest to the actual traffic law, and provides each vehicle with the optimal vehicle route from the microscopic level The optimal selection scheme realizes an economical and environmentally friendly travel mode based on real-time road conditions with less time-consuming and low-cost travel, and further provides basic data for traffic control decisions. traffic control.

Description

Technical field: [0001] The invention belongs to the field of traffic control, and in particular relates to a route selection method for traveling vehicles based on historical behavior portraits. Background technique: [0002] With the development of urban scale and intercity traffic, the scale of expressways has been continuously expanded. The highway network environment is easily affected by various factors, resulting in the closure or addition of road sections, which provides more diversified options for vehicle travel paths, and also brings certain challenges to the relevant departments of road maintenance. [0003] The route selection of travel vehicles is not only related to the distance between the departure place and the destination, but also related to the toll rate of the expressway. For travelers, it is necessary to choose an economical route that takes as little time as possible; for policy-making departments, it is necessary to simulate the changes in road netw...
