Abstract

The invention discloses an integrated road traffic information acquisition system including a noise monitoring unit, a video traffic flow detection unit, a data processing and storage unit and a background management unit; the noise monitoring unit records the traffic noise data including weighted sound pressure level data, statistical sound pressure level data and spectral data, and the video traffic flow detection unit is used for acquiring the traffic flow, speed, vehicle type, time headway and other traffic data in real time. The data processing and storage unit is used for storing the traffic noise data acquired by the noise monitoring unit and the traffic flow data acquired by the video traffic flow detection unit. The background management unit is used for performing interactive operation with the data center and the monitoring terminal to localize the instructions of the monitoring terminal and the data center. The integrated road traffic information acquisition system has the characteristics of simple structure, high automation, and all-weather monitoring, can synchronously acquire the traffic noise data and traffic flow data in real time, and provides a large amount of basic data for the road traffic noise source strong emission model.

Description

technical field [0001] The invention relates to the field of road traffic information collection, and more specifically, relates to a comprehensive road traffic information collection system capable of simultaneously obtaining traffic flow data and traffic noise data. Background technique [0002] With the rapid development of economy and technology and the increasing urbanization process, the number of cars owned by residents has also shown explosive growth. The rapid growth of private car ownership has also brought about prominent urban road traffic noise pollution. In 2014, the average equivalent sound level of regional environmental noise in 113 key environmental protection cities across the country was 54.4dB(A), while the average equivalent sound level of road traffic noise was 67.6dB(A), which is higher than the equivalent sound level of regional environmental noise. The average is 13.2dB(A) higher. It can be seen that the noise pollution on both sides of the road i...
