Multimode public transportation transferring method in urban congestion period

Abstract

The invention discloses a multimode public transportation transferring method in an urban congestion period, which comprises the following steps of: step 1, constructing an urban ground-level road network based on real-time traffic information, and dividing different road sections of the urban road into a congestion road section and un-congestion road section; step 2, setting functional weight parameters for calculating costs of a ground bus, a subway and a public bicycle; step 3, establishing an urban public transportation weighted directed transferring network T; step 4, establishing an urban subway directed weighted network S; step 5, establishing a weighted directed public bicycle network B with the urban bus connected with the subway; step 6, by combining with the T network, the S network and the B network, calculating a cost function value, and adopting a breadth-first algorithm to obtain an optimal transferring solution. The multimode public transportation transferring method in the urban congestion period gives consideration to the characteristic that the short-distance tripping way by using the public bicycle and subway is not affected by the congestion of the ground road, accordingly provides the multimode transferring method to adjust the transferring solution automatically based on the congestion condition of the road surface, and enables the influence from the congestion to be minimum.

Description

technical field [0001] The invention relates to network science, in particular to a multi-mode bus transfer method during urban congestion periods. Background technique [0002] Urban public transportation is an important infrastructure that is closely related to people's real life, and its basic task is to provide passengers with safe, convenient, rapid, punctual and comfortable travel conditions. However, with the process of modernization and the development of urbanization, urban traffic has become very congested. In order to improve the current congestion situation, many cities in China have begun to devote themselves to the construction of subways and public bicycles. On the one hand, because subways and public bicycles are not restricted by traffic congestion, travelers can quickly choose their own transfer methods. By choosing a suitable means of transportation that is not restricted by traffic congestion at the edge of the congested area, the travel time can be effe...

Problems solved by technology

On the other hand, rail transit facilities such as buses cannot realize point-to-point transportation, and public bicycles have improved this defect to a certain extent. Its connection range is small, and it can even intersect with pedestrian traffic.
