In this paper, the model was applied to the actual city area with the existing road network. After constructing network of wider city area in computer model, we simulate the traffic impact generated by new development in the CBD. It was found that road congestion due to the new development is observed not only on immediately surrounding road but also in much wider area in the city, because of the change of the shortest path demanded by other traffic flows.
