The gradation relationship model and application of urban multimodal transit networks

Abstract

Aiming at the situation that the rational allocation of multimodal transit networks planning is ambiguous in China, firstly, the characteristics of residents’ transit trip distance are analyzed, and the distance distribution model of residents’ transit trip is built with double parameters Weibull distribution; secondly, preponderant trip distance of each transit network is presented based on the generalized travel cost; finally, the gradation model of urban multimodal transit networks is proposed based on the balanced analysis of supply and demand. Moreover, taking transit networks of Harbin as an example, a reasonable scale and gradation relationship of each transit network of Harbin in 2020 is calculated; the results are matched with the expected demand in 2020, which demonstrates that the model is reasonable and feasible. This paper provides a new approach for determining the reasonable gradation relationship of multimodal transit networks.
