Abstract: With rapid development of urbanization in China,traffic condition has become even worsening,therefore,it is the primary task of the urban transport strategy to build up the modern transportation systems and traffic information management system earlier．It is desired aims of traffic flow research to find out the algorithm for traffic flow which could properly represent the fundamental laws of traffic flow so as to better guide the management and control of optimizing local traffic．Based on the theories of micro-variables and cellular automaton,the model of algorithm for traffic flow was put forward,after designing and numerically modeling the algorithm for traffic flow, the paper predicted the ideal traffic flow and trip distribution situation,deepened the understanding of the internal mechanism of traffic flow in various phenomenon and predicted the most actual situation of traffic flow and made fundamental work for traffic flow simulation and real-time traffic control as well.

Key words: Micro-traffic flow model,Cellular automaton model,Dual-route decision-making model
