Research on Pedestrian Route Planning Algorithm Based on Low Exhaust Intake

Abstract

The main pollution source of urban air quality is vehicle exhaust pollution, in which a variety of toxic and harmful substances seriously affect the health. In this paper, a pedestrian path planning algorithm based on low exhaust gas intake is proposed. The vehicle exhaust collection device is used to collect and analyze the concentration of harmful gases on the road edge, and calculate the air quality index of each section by AQI calculation method. In order to reduce the intake of harmful gas in the existing road network model, the route planning of the minimum harmful gas intake from the starting point to the destination node is given by using the A* search algorithm. Experiments show that the algorithm can effectively avoid the large traffic flow and serious air pollution section.
