Road segment detection method considering traffic demand and road network operation efficiency

Abstract

The invention provides a road segment detection method considering the traffic demand and road network operation efficiency, which obtains the generalized travel cost and other information of each urban road in an urban road network by collecting and sorting related travel data of the urban road. By measuring the traffic demand and establishing a travel demand OD matrix and an algorithm based on auser equilibrium model, it is possible to find invalid road segments in the urban road network under the current traffic demand level. Through matrix transformation of the road segment cost and the route cost, the method allows traffic managers to know the timing of the change of the effectiveness of the road segments when the traffic demand changes. The advantages of the invention lie in that the detection method can be used to analyze the validity of the road segments in real time and can be used to analyze complex urban road networks of multiple OD pairs; and with the method, the traffic managers do not need to change hardware facilities of the road network and can timely restrict and open such road segments in the road network to improve the overall operation efficiency of the urban road network.

Description

technical field [0001] The invention relates to a road section detection method, in particular to a road section detection method considering traffic demand and road network operation efficiency. Background technique [0002] With the rapid development of information technology in the field of urban transportation, the demand of the whole society for travel information and technology has been increased. As one of the main purposes of urban traffic management, keeping the urban traffic network smooth plays an important role in the production and life of urban residents, and improving the overall operating efficiency of the urban road network is the main means to keep the urban traffic network smooth. As an important way to keep the urban traffic network smooth, it plays an important role in traffic management. From the perspective of urban traffic network model, improving the overall operating efficiency of the network is by no means a static problem. The traffic road netwo...

2. Since these two inventions are for the calculation and judgment of the instant state of the road network, there is no method for analyzing the road state that may change in the future, so the above two inventions fail to establish the state of the road network based on the consideration of changes in traffic demand Therefore, it can only rely on real-time collected data to judge the road traffic status in real time, and cannot judge the status of the road according to the change of traffic demand.

3. Since the above two inventions are only the detection of the existing road network, and no optimization scheme has been proposed, based on the detection results of the above two inventions, it is impossible to directly formulate measures to improve the operation efficiency of the road network
