Evaluation On Vehicle Emissions Of Intercity Terminals

With the sustained and rapid economic development, motor vehicle holdings grow yearafter year, motor vehicle emissions have become one of the major sources of urban airpollution in our country. As the node of highway road transport network in our country, roadtransport terminals undertake the main task of highway passengers and cargo transportation inChina, meanwhile cause the air pollution problem of passenger station and it’s surroundingareas. Nowadays, although some standard proposed constraint rules for vehicle emissions inthe passenger station, there is no specificity for the passenger in quantitative analysis systemof vehicle exhaust emissions. Therefore, the highway passenger vehicle pollutantsquantitative research proposed by this thesis，has important practical significance to control,quantization and reduce pollutant emission, evaluation station pollutant emissions andestablish reasonable measures.On the basis of analyzing the environmental elements of the highway passengerstations, this thesis choose a new generation of mobile source emissions prediction modelMOVES in the United States as vehicle emissions quantitative tools. According to theprinciple of the station scene MOVES model, it proposes the highway passenger demandmodel data input, taking XI’AN South Intercity Terminal as the research object, making fieldresearch for traffic into and out of the station, the station layout, scale, etc; Using GPSspeedometer measured the running status data of the main station and outside of operatingpassenger car and the short stroke unit analysis method is used to establish the passengervehicle driving cycle; Using Driving Cycle Model of the MOVES model, combining withlocal parameters to calculate the emissions of parking lot, traveling area, driving area, startwork area respectively; finally simulating the effects of using different fuels on emissions ofvarious pollutants in the passenger vehicle and putting forward relevant measures to reducethe emissions within the station.
