Vehicle service attribute decision optimization method based on flexible bus connection system line

Abstract

The invention belongs to the field of public transport systems, and relates to a vehicle service attribute decision optimization method based on a flexible bus connection system line. According to the invention, the connection flexible bus takes the rail transit junction station as a starting point and an ending point in a specific area, the connection service between a demand point and the junction station is provided according to real-time demands, seamless connection of a 'bus + subway' trip mode can be realized, the trip time cost of passengers can be saved, the bus service level can be improved, and the public transport attraction can be improved; the buses in the system can flexibly run in a certain area according to real-time passenger flow demand information collected by a dispatching center, bus transportation resource allocation is planned and optimized as a whole, the vehicle passenger carrying rate is improved, the operation cost of a bus enterprise is reduced, and social benefits are maximized; and meanwhile, through a cooperative scheduling strategy of the community buses and the hub connection flexible buses, the bus operation efficiency is improved, more travelers can be attracted to select a public transport travel mode, and the urban public transport development can be effectively promoted.

Description

technical field [0001] The invention belongs to the field of public transport systems, and relates to a vehicle service attribute decision-making optimization method based on a flexible bus connection system line. Background technique [0002] In recent years, my country's urban public transport network has gradually entered a new era with rail transit as the framework and ground public transport as the support. The annual passenger volume of the subway in some megacities gradually exceeds that of conventional public transport. The functions and positioning of different travel modes urgently need to be optimized and optimized. Adjustment. The attractiveness of conventional buses to passengers is gradually weakening, and the unbalanced development between rail transit and conventional buses has reduced the overall operating efficiency of the urban public transportation system; in this regard, scholars at home and abroad have taken measures such as giving priority to bus signal...

AI Technical Summary

Problems solved by technology

For example, Chengdu has opened 93 connecting bus lines and 108 community bus lines, which are divided into three modes: all-day operation, weekday operation only, and morning and evening peak operation. However, there are many problems in the network layout and operation strategy. : First, in terms of online network layout, there are prominent problems such as empty vehicles during off-peak periods or crowded vehicles during peak periods, and some lines overlap with ordinary bus lines, resulting in waste of some bus resources; The waiting time of passengers is longer during peak hours, without considering the interaction mechanism between bus operation indicators and bus service level
