Research On Exhaust Emissions Of Motor Vehicle Intersections Based On Microscopic Traffic Exhaust Simulation Platform

With the continuous and rapid growth of China’s motor vehicle ownership year by year,while motor vehicles have brought many conveniences to the daily travel and transportation life of modern people,a series of problems such as environmental pollution and energy consumption caused by their exhaust emissions have been The city’s ecological and environmental security has caused a series of serious effects that cannot be ignored.Therefore,under the circumstances necessary to ensure the safe travel of motor vehicles,how to minimize the impact of motor vehicles on the exhaust pollution of the ecological environment is undoubtedly a crucial issue.In recent years,the country has continuously increased its efforts to prevent and control motor vehicle exhaust pollution and adopted a multi-pronged policy.At the same time,it is undoubtedly a relatively safe way to effectively reduce motor vehicle exhaust emissions by formulating more optimized traffic management and control strategies.Economical and effective means of traffic management.Although traditional traffic control and measures pay more attention to the improvement and improvement of the efficiency of motor vehicle traffic flow,with the increasing pollution of motor vehicle exhaust,the effectiveness of its environmental indicators is included in the importance of evaluating urban traffic control and measures.The category of indicators has gradually attracted more attention from more experts,scholars and transportation decision makers.This article puts the foothold on the study of the combined scheme of traffic management and control methods at the intersection of the city.Through the simulation of the traffic flow at the night rush hour of the city intersection,it is analyzed that various traffic control methods reduce the reduction under different combinations.The important effectiveness of motor vehicle exhaust emissions at intersections provides good traffic decision data support for local governments and road traffic management departments to optimize the management of the transportation system in critical periods.Based on this research purpose,in order to study and formulate effective measures and strategies to effectively control the total amount of vehicle exhaust emissions,on the basis of an in-depth analysis of the current domestic and international micro-traffic emission technology research trends in the field,this article chooses advanced micro-transport The flow simulation software Vissim and the advanced vehicle performance analysis system software Autonomie are integrated to establish a microscopic traffic exhaust simulation platform.A crossroad in Yuhong District,Shenyang City,Liaoning Province is selected as the object of simulation research and a road network example is constructed.After analysis,several typical traffic management and control methods that meet the conditions of simulation and simulation experiments were selected,and different control and control methods were combined to design a simulation program.The simulation and simulation experiments were carried out,and the traffic analysis results were compared and analyzed to obtain traffic.The impact of different control schemes and measures on the total emissions of motor vehicle traffic.To further summarize the specific effectiveness of these management and control measures in practical application,the advantages and disadvantages of the measures and their applicable conditions,it provides a reference for the research of the government and relevant departments of road traffic management.
