Efficiency weight calculation and public transport plan performance evaluation method in public transport complex network

Abstract

Provided is an efficiency weight calculation and public transport plan performance evaluation method in a public transport complex network. The method comprises improvement of a conventional cross sectional flow estimation method; and improvement of a public transport efficiency weighting PTEW method. In an improved algorithm, when the passenger load factor surpasses a certain level, passengers are more likely to miss a bus, resulting in more waiting time, which reduces public transport efficiency; while such effect is not considered in a traditional PTEW algorithm. Compared with an actual public transport plan, there are two plans: the least number of stops and the least number of transfer times; the improved algorithm can calculate public transport efficiency between two stations in a more scientific manner, thereby helping to provide a public transport network optimization strategy by utilizing characteristics of the public transport complex network; and meanwhile, the invention further proposes the improved algorithm of the public transport efficiency weighting PTEW method with more factors being considered, and thus efficiency weight between the two bus stops is defined in a more scientific manner.
