Problems solved by technology

At the same time, traffic noise reduces the work and study efficiency of citizens, and environmental disputes caused by this occur from time to time, which brings great pressure to urban road traffic construction.
At present, domestic and foreign urban planning has not paid much attention to the noise problem. The traditional road green space planning and design mainly starts from the visual effect of the landscape, lacking systematic road traffic planning and design and optimization control methods based on noise reduction. The guiding significance of noise planning design and optimal control is not strong
On the one hand, it increases the cost of noise control in the later period after the road traffic is completed, and on the other hand, it affects the landscape environment on both sides of the road traffic that has been repaired later

Embodiment

[0036] Take the downtown area of ​​Nanjing, Xinjiekou area of ​​Zhongshan Road as an example. Such as figure 2 As shown, the area enclosed by the box is the target area.

[0037] The present invention provides a 3D noise map-based noise-reduction oriented optimization control method for urban road greenbelts. The 3D noise map is obtained through the noise measurement of the target range and the computer intelligent simulation, and the noise effect is evaluated in combination with the noise standard of the acoustic environment functional area, and then According to a set of noise-reduction-oriented planning and design module matrix, a noise-reduction-oriented optimal control scheme configuration is carried out for urban road green spaces. The specific program steps are as follows:

[0038] Step 1: Obtain the original topographic map information of the measured urban area, divide the measurement area on the original topographic map with the city block as the unit, and set the...

Abstract

The invention discloses an urban road greenbelt noise reduction guiding optimization control method based on a 3D noise map, and the method comprises five steps: road selection, current noise actual measurement, 3D noise map construction, noise evaluation, and noise reduction module matrix building. The 3D noise map construction is the data simulation for the whole measurement region difference calculation based on actual measurement noise data. The noise evaluation is the standardized judgment of the noise value of a road according to the traffic noise standard of the road. A noise reduction module matrix comprises a noise reduction road greenbelt land module, a noise reduction guide structure module, a noise reduction guide facility equipment module and a noise reduction guide plant configuration module, and three types of targeted suggestions are proposed according to the width condition of a noise reduction road greenbelt land. The method saves the treatment cost after a road is constructed and put into use, reduces the impact on the surroundings from the urban road noises, and can minimize the noise pollution caused by various types of urban roads.

Description

technical field [0001] The invention belongs to the technical field of urban planning, and relates to an optimal control method for urban road green space noise reduction guidance based on a 3D noise map. Background technique [0002] In the stage of rapid urbanization, the urban population density is increasing, and the traffic load of urban roads is also increasing. Traffic noise has become the main noise source in the city, affecting the normal life of citizens and causing damage to people's physical and mental health. At the same time, traffic noise reduces the work and study efficiency of citizens, and environmental disputes caused by this occur from time to time, which brings great pressure to urban road traffic construction. At present, domestic and foreign urban planning has not paid much attention to the noise problem. The traditional road green space planning and design mainly starts from the visual effect of the landscape, lacking systematic road traffic planning ...
