Abstract

The present invention provides a multi-stage road network section traffic capacity determination method. The method comprises the following steps: S1, obtaining the road distribution condition in a road network, comprising dividing the road network into m sections, taking X as a road section set, dividing jth section xj into n slope sections, taking Y as a slope set and taking Z as a slope length set; S2, calculating the road capacity Qj when the jth road reaches the maximum efficacy; and S3, according to the road capacity Qj, calculating the capacity Q of the whole road network: (img file='DDA0001302194120000011. TIF' wi='269' he='164'/). According to the invention, the multi-stage road network section traffic capacity determination method can perform accurate calculation of the multi-stage road network traffic capacity and obtain an accurate result so as to image the application range.

Description

technical field [0001] The invention relates to a traffic analysis method, in particular to a method for determining the traffic capacity of a multi-level road network section. Background technique [0002] In the field of transportation, the traffic capacity of the road network is one of the key elements for analyzing the balance of the road network and traffic coordination. In the prior art, the methods for determining the traffic capacity of the road network include time-space consumption method, linear programming method, cut-set method, Traffic allocation simulation method, supply analysis method and narrow road network capacity analysis method, etc., but the existing methods are generally based on theoretical models, their limitations and scope of application are small, and the final analysis results are not accurate, especially in multi-level roads. In the road network, the existing methods cannot be used. Even if the road network is analyzed ideally, the results are ...
