| 摘 要： | 以1分钟为单位时间间隔,以1小时为1个样本观测时段,通过实地调查获取了柳忠高速公路天水北路收费站连续13个小时的车辆到达数据。在此基础上,对高速公路收费站的车辆到达过程服从泊松分布这一假设进行了χ2拟合检验,检验结果表明:高速公路收费站的车辆到达过程服从泊松分布。

| Abstract: | A continuous 13-hour field investigation is conducted to monitor the arriving number of vehicles at the toll station of Liuzhong Expressway Tianshui North Road with interval unit of 1 minute and observation period of 1 hour. Based on the above survey data,the chi-squared test is carried out on the hypothesis that vehicles are assumed to arrive at a Poisson process at expressway toll station and the fitting test results conform to our assumption. |
