Research on Travel Time of Basic Road Based on Cellular Automata

The focus of the paper is the research of travel time of urban basic roads with multi-lane and channelized sections as well as traffic signal control.A cellular automata model CAUB is established based on NaSch model through the description of basic move rules,lane changing features,and responses to signals.At last CAUB is used to simulate travel time of basic roads.Results show that the travel time on basic roads displays break nature and is influenced by flow and signal setting,which relates to flow structure.
