 Planning and management of an important step is to attach importance to the analysis of urban road traffic noise prediction method. These include: strengthening roads, including highways, environment impact assessment, road traffic noise propagation and prediction of road traffic voice sound methods of research; based on traffic volume, the proportion of vehicles, average speed, street layout, building layout, balcony and city traffic noise prediction, this way, we can estimate the present and future road transport residents along the environmental interference, and noise control planning and engineering measures to implement the construction project environmental protection engineering design in order to reduce the troubles. 
 The development of more stringent vehicle noise control standards and regulations, and traffic noise monitoring system, strengthen transportation construction and management, to accelerate the pace of reducing urban traffic noise. 
 First, to promote the development of low-noise vehicles. The most direct measures to control road traffic noise control noise of the vehicle itself. In order to design low-noise vehicles, in addition to using high-efficiency exhaust muffler, the most important measure additional engine noise insulation to reduce engine noise, while the gearbox, drive shafts, cooling fan, and tire noise mechanism on the basis of control . To improve and enhance the noise performance of the car, try to equip and popularity of the engine with acoustic enclosures and impedance compound efficient exhaust muffler to reduce car driving noise; lights flashing signal or low frequency elegant music instead of in speaker can greatly reduce or eliminate the noise pollution caused by the car horns. 
 In order to promote the development of the automobile industry and focus on the study of low-noise vehicles, should be based on the status and level of economic development of China's automobile industry, re-enactment of more stringent motor vehicle noise standards, so that the vehicle design and manufacturing level can be greatly improved. more engineering and technical personnel engaged in the study of automotive noise control. 
 Second, to promote the development of low noise road surface. Reduce tire road noise to improve the tire structure, to improve the pavement material structure of the two. But to improve the noise of the tire structure is limited, and the high cost of the study, therefore, after a way to improve the pavement material structure has become the main research directions to reduce tire / road noise.
