Recognition method for key sections of highway network

Abstract

The invention discloses a recognition method for key sections of a highway network, which comprises the steps of firstly dividing the highway network into a plurality of sub community networks by using a community dividing algorithm; then modeling the highway network according to a probability assumption method, solving to acquire candidate key sections in each sub community network; and then finding out final key sections from the candidate key sections by adopting a dynamic planning method to act as key sections in the highway network, and enabling combinations investing the key section to realize the highest traffic efficiency of the highway network. According to the recognition method provided by the invention, key sections in the highway network are dug according to the traffic flow and highway network characteristics, the key sections in the highway network can be dug out accurately and efficiently, and a problem of key section digging is solved, thereby being capable of turning into an effective means of digging key sections in the highway network in practical application, being capable of providing a reference basis for overall planning of a transportation department, and providing a support means for the highway management staff to manage the highway network efficiently.

Description

technical field [0001] The invention relates to the fields of intelligent transportation and complex network analysis, in particular to a method for identifying key road sections that play a key role in the operation of expressway networks. Background technique [0002] In recent years, the rapid development of my country's expressways has greatly shortened the distance between provinces and important cities, effectively reduced production and transportation costs, and changed people's lifestyles. With people's increasing reliance on highway travel, the problem of high-speed congestion caused by unexpected accidents and road factors has also attracted the attention of people from all walks of life and has become a widely discussed social phenomenon. High-speed congestion brings economic losses, affects people's travel safety and comfort, and reduces travel experience. [0003] There are some extremely important traffic hubs in the expressway network, and these road sections...
