An optimization method of bus line network layout

Abstract

The invention discloses a public-transit-network layout optimization method. The method comprises the following steps that key indexes determining backgrounds ksi<1> of travelers are obtained; parameter indexes determining the public transit operation service level eta<2> are obtained; key control indexes determining the tolerance eta<1> of the travelers are set; key indexes S<x> influencing the travelers to judge the public transit service satisfaction degree are determined; control indexes E<BX> influencing public transit operation benefits are determined; the traffic capacity C of a public transit network of a city is worked out; an optimal object model of the layout of the public transit network is established; a layout scheme of the public transit network of the city is determined; whether the layout scheme of the public transit network meets the requirements of the optimal object model or not is judged, wherein if yes, the layout scheme of the public transit network is output, and if not, measurement and calculation in the last step are conducted, and the layout scheme of the public transit network is further optimized. By means of the public-transit-network layout optimization method, contradictions between public transit service differences pursued by different types of travelers and the public transit operation benefits can be balanced, the public transit service satisfaction degree can be increased, and the degree of loyalty of the travelers to the public transit service can be increased.

Description

technical field [0001] The layout of urban bus routes is the core issue in the field of bus operation and dispatch. This method proposes an optimization method for urban bus line layout considering the satisfaction of bus service, which can maximize the balance between the travel satisfaction requirements of travelers and the operating benefits of bus companies, and provide scientific and reasonable urban layout for bus operation managers. The bus line provides a basis and belongs to the technical field of public transportation. Background technique [0002] Since 1994, cities in my country have begun to pay attention to the priority of public transport, hoping that the public transport system can solve the problem of urban traffic congestion. Although various cities have given great support to the public transportation system in terms of financial subsidies and preferential policies in recent years, the actual utilization rate of public transportation has not improved sign...

Problems solved by technology

If only the benefits of transportation companies are considered, it is likely to lead to a lower service level of public transportation and a lower degree of customer satisfaction, which will lead to a decline in the competitiveness of public transportation and damage the interests of public transportation companies on the other hand.

If we blindly pursue high customer satisfaction, the benefits of transportation companies may not be guaranteed, and the enthusiasm of transportation companies will be weakened, resulting in the failure of bus operations.
