Abstract:
In order to improve the efficiency of the overall road network, from the external manifestation of the unreasonable transportation network layout(congestion, over-smooth)problem, this paper analyzed the underlying causes of its formation. It was pointed that the reasons were the road network layout design failed to consider the transportation demand and the transportation flow didn't match the traffic flow. The optimization model of traffic network was built with four factors as decision variables, such as expense of section optimizing, opportunity cost of land occupation, transportation fee and network efficiency. Analysis result shows that the service efficiency of transportation networks after optimization is 60% more than that of traditional planning, so the model is reasonable feasible. 5 tabs, 2 figs,10 refs.
