交通事故影响下事发路段通行能力变化研究

随着社会经济的发展和城市化进程的加快，城市交通问题日益严重，城市道路通行能力受诸多因素影响，其中交通事故影响最为显著．本文以两起典型交通事故为例，对事发路段通行能力进行研究．结合交通事故中的实际情况，建立交通波理论模型，用MATLAB软件对交通数据进行分析和处理，得到事故所处横断面实际通行能力变化的折线和拟合曲线图．通过对比分析，得到两种典型事故中实际通行能力的变化情况，并对通行能力变化原因进行了详细阐述和科学评价．因此，文中的研究方法和结果具有一定的科学性，为城市道路交通管理提供了重要的参考依据．

Studies on Urban Traffic Capacity Change under the Influence of Traffic Accident

With the development of social economy and the speeding up of urbanization, transport problems have became increasingly prominent, urban road traffic capacity is influenced by many factors, but the most significant is traffic accident .To study the road capacity ,two typical traffic accidents as the example are used in this paper. Combining with the actual situation of road traffic accident, setting up the model of traffic wave theory, using MATLAB software to analyze and process traffic data, we received the actual capacity changes line and curve fitting during an accident in cross section. Through contrastive analysis, two kind of typical reasons of traffic changes are gotten, and traffic capacity changes are elaborated and evaluated scientifically. So the research methods and results in this paper are scientific, and also provides an important reference basis for urban road traffic management.
