摘要: 为了能深入分析我国城市路外停车场出入口接入主路车流的车头时距特性,论文以停车场出入口接入路段的影响区域作为研究对象,以城市常见的双向六车道的四幅路断面形式为例,选择南京市商贸大厦路外停车场出入口接入主路区域进行了数据的采集。综合运用数学方法与SPSS软件,分析了主路各车道的车头时距特性,分别建立了各车道的车头时距概率密度函数,主要研究结论有:①各车道的车头时距不服从正态分布,但是服从对数正态分布;②车道1的概率密度函数为 ;车道2的概率密度函数为 ;车道3的概率密度函数为 。研究结论为进一步分析车辆的变道特性提供了一定的理论基础。

Abstract: In order to analyze the headway characters of the main road at the sections of off-street parking access deeply in the cities of China, this paper chooses the influence area of the section of off-street parking access in the city as the research object. Also, the carriageway road including six lanes on two-direction was introduced as a typical example. By using the parameters observed from area of the section of off-street parking access in Nanjing Shangmao Building, a probability density function was established that described the characters of the vehicles on the main road by the method of SPSS and mathematics. Some conclusions can be drawn. First, the headway of all the lanes cannot be subjected to the normal distribution except for logarithmic normal distribution. Secondly, the probability density function of the first lane is , while the second is and the third is . It would be more beneficial for the further study on change-lane characters of the vehicles.
