摘要
文章结合沪宁高速公路研究了不同因素对高速通行能力的影响。因道路养护施工对高速公路通行能力的影响是通过基于交通流统计的分析模型分析并仿真施工区的通行能力。分析交通事故对高速公路通行能力的影响主要是研究高速公路交通事故的处理方式,并通过VISSIM仿真软件建立八车道高速公路基本路段上的交通事故模型进行分析。通过对流量、货车比例、车道数、坡度等影响因素的车道管理策略进行分析,研究车道管理对高速公路通行能力的影响,最后针对以上三个方面提出通行能力的提升策略。
In this paper,the impact of different factors on the highway capacity is studied in the context of the ShanghaiNanjing Expressway.The impact on highway capacity due to road maintenance construction is analyzed and the capacity of the construction area is simulated through an analytical model based on traffic flow statistics.The impact on highway capacity due to traffic accidents is analyzed by analyzing how highway traffic accidents are handled and the impact on highway capacity by modeling traffic accidents on the basic section of an eight-lane highway through VISSIM simulation software.The impact on freeway capacity due to lane management is analyzed through lane management strategies that take into account influencing factors such as traffic flow,truck ratio,number of lanes,and slope.Finally,the strategy of access capacity improvement is proposed for the above three aspects.
