Medium and small city bus line network design method based on whole-process travel perception time

Abstract

The invention discloses a medium and small city bus line network design method based on whole-process travel perception time. The method takes the line length, the total number of line network vehicles, the departure interval, the transfer frequency and the like as constraints and takes the minimum travel perception time of the whole passenger travel process as a target to carry out bus line design, and comprises the following steps: firstly, determining a bus stop set and first and last stop pairs, and generating an initial candidate line set by using a K shortest path algorithm; secondly, screening the initial candidate line set according to the line length and the sum of weight coefficients of bus nodes on each line to obtain a second-generation candidate line set; thirdly, a genetic algorithm and an exhaustion method are used for obtaining a third-generation bus line set, a bus trunk line scheme and a branch line scheme are determined, finally, the bus line network is adjusted in combination with the actual situation, the actual requirement is better met, and the method can provide a method basis for design of the bus line network of small and medium cities according to the design requirement of different levels of the bus trunk line and the branch line.

Description

technical field [0001] The invention relates to an urban public transportation planning technology, in particular to a method for designing a public transportation network in a small and medium-sized city based on the whole-process travel perception time. Background technique [0002] According to the "National New Urbanization Plan (2014-2020)", accelerate the development of small and medium-sized cities as the main direction of optimizing the urban scale structure, strengthen the guidance of industrial and public service resource layout, improve quality and increase quantity. At the same time, the rapid advancement of the national highway and high-speed railway network construction in recent years has also provided good conditions for the development of small and medium-sized cities. With the acceleration of urbanization, the level of motorization in small and medium-sized cities continues to rise, and the travel needs of residents continue to increase. More and more resid...

Problems solved by technology

[0003] From the supply side, due to the lack of systematic planning, the improvement of public transport services in small and medium-sized cities lags behind the increase in travel demand of residents; at the same time, it is difficult to show the advantages of public transport services in long-distance travel; The operating environment is harsh
