| Abstract: | Problems of transportation macro simulation model for urban road network system are studied and a simulation model which meets real characteristics of urban road network system is put forward.This model gives a simple and correct abstraction of direction difference in urban road network transportation characteristics space distribution and intersection delay, and based on the model,an algorithm for shortest path has been designed.1 tab,2 figs,5 refs. |

| Keywords: | urban road network transportation simulation model shortest path algorithm |
