Measurement method of green traffic vehicle exhaust emission based on spark algorithm

Abstract

There are some problems in the traditional measurement methods of green traffic vehicle exhaust emissions, such as large measurement error and long measurement time. This paper proposes a measurement method of green traffic vehicle exhaust emissions based on spark algorithm. By extracting the green traffic vehicle trajectory, and preprocessing the vehicle trajectory data through the batch descent gradient method, according to the green traffic vehicle trajectory data, calculate the concentration of the substances in the vehicle exhaust, and obtain the green traffic vehicle exhaust emission index; map, overlay and grid it, and build the green traffic vehicle exhaust emission measurement model. With the help of spark streaming in spark algorithm to modify the green traffic vehicle emission measurement model, the optimal solution of the model is the optimal value of vehicle emission measurement. The results show that the error of the proposed method is always less than 3%.
