Alternatives of Strategic Environmental Assessment for Road Traffic Development Planning——Case of Changchun City,China

摘要

On analyzing the achievement of the goal in the modern urban road traffic development planning,the alternative of Strategic Environmental Assessment for urban traffic planning should include the basic scheme,the extended scheme and the environmental protection scheme. This study from different perspectives designed the alternatives for Changchun's county-level road and urban road system planning,and used the method of System Dynamics to simulate,optimize and analyze those alternatives. Thereafter,some methods including the correlation function method were used to comprehensively assess and rank those alternatives for recommending two best alternatives with the consideration to the indicators,such as the total emission amount of CO,the total emission amount of nitrogen oxides,the noise value,the road construction cost,the fossil oil consumption and the traffic capacity. The result showed that the study would provide substantial supports for decision-makers to make more scientific decisions and promote the sustainable urban traffic in Changchun City.
