| Abstract: | By Using the theory of the linear program(LP),this paper has methodized the mathematic model of an urban traffic control system(PCS) and obtained the optimal result.By using the method of this paper,all parameters,which are cycle,offsets,bandwidths and green times,can be optimized simultaneously.This paper could provide the theory basis for us to control traffic flow and will be a good method to deal with vehicle crowd and jams. |
