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.

K-S检验法在SPSS的非参数检验中，它是用样本本身的信息来检验样本来自同一个总体(正态分布、均匀分布、泊松分布或指数分布)假设的一种统计检验方法。K-S检验主要是运用某随机变量X的顺序样本来构造样本分布函数，使得能以一定的概率保证x的分布函数F(x)落在某个范围内。检验结果见表3
