非机动车闯红灯数据的统计分析

Statistical Analysis of Data of Non Motor Vehicles Running Red Lights

针对城市交通问题,分别采用QQ图和统计检验方法,对上海市某路口非机动车闯红灯的数据进行统计分析,得出违章数据服从于正态分布.按照贝叶斯理论,预测车辆通过路口时,没有遇到非机动车闯红灯的概率,并对统计结果进行了相应的讨论.

For urban traffic issue,an investigation of non motor vehicles running red lights data in Shanghai was proposed with the QQ figure and statistical test,the data of non motorized red light running at a certain intersection was the normal distribution. Then,according to the Bayesian theory,the probability of non motor vehicles running red lights was predicted when crossing the junction,and the statistical results were discussed.
