Compatibility of traffic noise planning control and land use in intensive city

The optimal way to solve traffic noise pollution is the planning-control. But it is a problem that how to get a perfect balance between the control distance and the land use, especially in some intensive City, such as Shanghai, Hong Kong etc. This article intends to put forward some exploratory ideas about the distance control with the study on the sound field of urban traffic noise distribution. Different from Euro and USA, The traffic noise is a serious problem in most Asia City. At present, these governments limited the distance along the traffic roads to reduce the noise level, yet it restricted the land-use. We plans to sketch a 3D view spatial pattern different from the past horizontal sound field research. And then; we should propose a constructive restriction on the sensitive buildings along the distinct roads, such as the layout/height of the front and back buildings. This paper proposes a new idea about the planning space control along the traffic roads, and put forward different control requirements for sensitive buildings on heights/distance. It will be applied to solve the traffic noise of intensive cities, and promoted the harmoniously progress between cities' planning and land use.
