An Improved Traffic Planning Method and Its Application

Under the conditions of meeting the demands of capacity and service level, different planning schemes have different vehicle ratios, vehicle flow and vehicle speeds, and influence the environment and energy consumption further. It is necessary for the traffic system sustainable development how to obtain the corresponding environmental impact assessment and energy consumption analysis according to the known or calculable traffic planning schemes. By establishing the proper link between traffic planning modelsand environmental impact models, the paper makes an improvement on the classic “Four-Phase Model” traffic planning method, and the sustainable development prediction assessment is added. The improved planning method reinforces the environmental impact and resource consumption influence on traffic planning, conforming to the tendency of sustainable development. The example indicates the quantitative research on the problem is feasible.
