摘要
地下快速路的环境造成车辆不同的运行特征。运用交通监测数据,并进行自然驾驶试验,通过数理统计的方法,分析了地下快速路相对于地上快速路在车速、车头间距、侧向位移等车辆运行指标上的差别。指出了这些差异对地下快速路车辆安全运行可能带来的影响,从车辆运行安全性的角度对地下快速路安全改善提出了建议。
The environment of underground expressway will lead to different vehicle operating characteristics.Through traffic monitoring data and natural driving test,the differences of vehicle operating index of underground and ground expressways are analyzed focusing on traffic speed,space headstock and transversal displacement by means of mathematical statistics.The influence caused by these differences to vehicle safe operating on underground expressway is pointed out,and several suggestions on underground expressway safety improvement are proposed from the aspect of vehicle operating safety.
