Abstract
The research embodied in this paper presents a new approach for the optimal design of the traffic channelization and traffic signal control in Chinese medium and small city. Firstly, the traffic characteristic of intersection is analyzed. Secondly, the structure of the design process between traffic channelization optimization and traffic signal control optimization is presented; there are two phrases of the design process: current optimalproject and the future optimal project. The optimal project of the traffic channelization and traffic signal control is got using the new design process after the application, by the simulation, the effect is improved distinctly.
