Research On The Improving The Traffic And Environment Of Wangjing District With PRT-based Export Line Mode

With the advancement of China's industrialization and urbanization,the road network has developed rapidly and the number of urban motor vehicles has increased.As of 2017,the number of motor vehicles in Beijing has reached 5.64 million.The motor vehicle generates a large amount of dust during the road driving,and the engine itself also generates a large amount of fine particulate matter such as PM2.5 and heat.The entire mode of travel of roads and motor vehicles caused huge air pollution and urban heat island effects.Especially since the last two years,the entire North China region has been shrouded in smog.The government has introduced a large number of policies and regulations to control air pollution.The social anxiety and social contradictions induced by urban air pollution problems have become the practical problems facing public governance in China.Although there has been a lot of research and practice on the analysis and evaluation of air pollution in motor vehicles and roads,there has not been a comparison study between a new sustainable transportation mode and traditional transportation mode.The impact and improvement of the model on the air environment,urban heat islands,and urban traffic.This has become an urgent problem to be solved in urban construction to achieve the goal of winning the blue sky and defending the world with sustainable development.PRT personal rail transit mode is a kind of land-saving,energy-saving,peer-to-peer,safe and efficient sustainable travel mode.It has great advantages for solving a series of problems such as air fine particle pollution,urban heat island effect,urban congestion and so on brought by the current mode of travel.It provides a good solution for the sustainable development of urban construction.The first two chapters of this paper firstly sort out the background information of personal rapid transit PRT theory,vehicle particulate matter emission,related concepts,and Beijing road planning and urban road grading,and summarize the current academic research and cases at home and abroad.The research objectives,research methods and specific contents of this paper are summarized.The third chapter analyzes and conducts on-the-spot investigations on selected roads and green areas in the Wangjing area of Chaoyang District,Beijing from a macro perspective.According to the standard of Urban Road Traffic Planning and Design,the roads in Wangjing area are classified and sorted.Investigate the existing road network in the area and the climate data of the selected green space.Through the analysis of the data,it summarizes the climate characteristics of the existing models in the current mode and the need for improvement.The fourth chapter proposes a new planning concept for the urban travel mode of Wangjing from the perspective of PRT personal fast transportation mode,including PRT site concept,PRT network concept,PRT system operation strategy.The fifth chapter compares the road environment under the existing road motor vehicle traffic and PRT personal fast traffic mode,and predicts the green space area under the PRT-oriented travel mode.Envi-met is used to simulate the road and green landscape in the two modes to form effective data results,so that the two modes can be compared more accurately.Verifying the improvement of the overall road traffic environment in the Wangjing area by the PRT system...
