Abstract:

Public transport system is an important part of the urban integrated transport systems, and the public transport systems are distinct according to different city types and sizes. Due to the current status of the city’s rapid development and the rare researches on the equilibrium evaluation on the transit network, this paper discusses the main features of the conventional public transportation system in medium-sized and small cities, and analyzes the main problems on the layout of the public transport. It applies the Gini coefficient theory to the research of urban public transportation network evaluation. Started from efficiency and equity, the paper establishes related evaluation system and measures the equilibrium on the evaluation method of the medium-sized and small cities. At the last section, the evaluation on the layout of public transportation network in Langfang City is analyzed for case study.
