Embodiment Construction

[0063] The present invention will be further described in detail below with reference to the accompanying drawings.

[0064] like figure 1 As shown, the method for analyzing the influence scope of overflow traffic flow after the dedicated bus lane is set up according to the present invention includes the following steps:

[0065] Step 1. Map the urban road network to a dual road network:

[0066] Primitive topology or dual topology are two methods to obtain the topology of urban road network. In the dual topology, the road segment is regarded as the node, and the intersection is regarded as the connecting edge. Through the mutual conversion between the node and the line, the importance of the line in the entire network and the relationship between the lines are easier to identify. The more adjacent road segments of a road segment in the road network, the higher the centrality of a road segment in the road network, and the greater the probability of being visited by travelers...

Abstract

The invention relates to a method for analyzing the impact range of overflowing traffic flow after the bus lane is set, comprising the following steps: 1. Mapping the urban road network to a dual road network; 2. Designing the transfer probability; 3. Using the transfer probability, based on the agglomeration algorithm The road sections are clustered to obtain the best clustering result. 4. The sub-area where the road section of the bus-only lane is located in the best clustering result is the influence range of the overflow traffic flow after the bus-only lane is set. The data required by the invention is easy to obtain and does not require detailed travel distribution data; it has strong operability and low computational complexity; the accuracy of confirmation of the scope of influence is high, and it is convenient for further detailed analysis in the later stage. The path information marked by the sub-areas can provide a structural basis for the future formulation of congestion control and congestion charge collection policies.

Description

technical field [0001] The invention belongs to the technical field of traffic planning. Specifically, it involves the establishment of dedicated bus lanes, the overflow traffic flow caused by the urban road network, and the analysis method of the influence scope of the traffic flow operation in the urban road network. Background technique [0002] The construction and reconstruction of the urban road network and the analysis of the impact on the traffic operation in the urban road network are an important key technology in the field of traffic planning and an important basis for assisting the decision-making of traffic management. At present, the number of motor vehicles in the city is increasing explosively, and the opening of dedicated bus lanes has become an effective measure that can not only ensure the priority of public transport, but also save the cost of infrastructure construction. However, the dedicated lane itself needs to monopolize part of the road resources, ...
