Abstract:

From the"increment era", the scale of road network in Xian has entered the era of "increment" and "stock". Traffic congestion and environmental pollution are becoming increasingly prominent. It is necessary to follow the green and low-carbon philosophy and plan the construction of urban road network in order to reduce the impact caused by the traffic congestion and environmental pollution. By investigating the current urban road network, the major problems existed in the road network are analyzed and summarized. The targets, strategies and requirements for planning the road network construction are proposed so as to improve the operation efficiency of road network, reduce the carbon emission, enhance the sustainable development of urban traffic and construct the more flexible livable city.
