Travel vehicle path selection method based on historical behavior portraits

Abstract

The invention provides a travel vehicle path selection method based on historical behavior portraits, which is used for solving the travel vehicle path selection problem in the prior art. According tothe travel vehicle path selection method based on the historical behavior portrait, a vehicle portrait is established based on the traffic characteristics of vehicles in historical traffic data, a time cost traffic model is constructed, and travel vehicles adopt the constructed traffic model to perform path selection. According to the travel vehicle path selection method based on the historical behavior portraits, vehicle travel features of historical traffic data are fully extracted, an optimal cost path selection method closest to an actual passing rule is found, an optimal selection schemeof a vehicle path is provided for each vehicle from a microcosmic level, an economic and environment-friendly travel mode with less travel time consumption and low cost based on real-time road conditions is realized, basic data is further provided for traffic control decisions, and a traffic control department adopts the constructed passage model to judge the route selection of travel vehicles soas to perform effective 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...

Problems solved by technology

The premise of the application of these path planning algorithms is to know which accessible points are available, and when the original data does not include the specific driving path of the vehicle, it is impossible to simply use the above algorithms for calculation
