Density of City Bus Lines is the key index in the planning of City Bus Lines.

Planning method of Beijing future public transit network based on small world network;

The planning of public transit network in small-and-medium-size cities based on graphics theory;

Study on the Planning Method in Guiyang Public Transit Network;

On the basis of considering each factor of urban public traffic line network,the decision-making method for the optimization of urban public traffic line network is set up by grey theory and fuzzy theory.

A new method of public traffic line network optimization is presented by particle swarm algorithm.

With Huai’an economic development, urbanization accelerates, the size of cities in the expansion, the new residential building, former Huai’an urban public traffic line network is not adapt to the new changing, so public transport efficiency drop, new regional has little or no public transport links and other issues.

The algorithm PSO of adjustment and optimization for public traffic network;

Cosine prioritizing method for the optimization scheme of public traffic network based on information entropy;

For the reasons that different cities and their different development levels bring about different layers of traffic demands, a classification planning method for urban public traffic network is suggested.

From urban transit networks to various complex networks;

The authors clarify the structure of transit network, set up a new simulation analysis method for the transit based on the analysis element and build up analysis model for bus line and GPSS simulation model for bus stop, and propose a method to build up the analysis and simulation model of transit network combined with case study.

This paper proposes a classification of the research on the sub-problems from the view of objectives, constraints, and methodologies with a focus on transit network design and scheduling.
