| 摘 要： | 通过计算与仿真相结合的方法研究冰雪条件下信号交叉口通行能力的衰减规律,计算结果显示,冰、雪条件下信号交叉口通行能力分别只有正常条件下的63%～66%和46%～52%;仿真结果也表明,冰雪条件下车辆通过信号交叉口时平均速度大大降低,行程时间、排队长度、平均延误等参数均有较大程度的增加。

| Abstract: | By studying the traveling capability attenuation rule of signal intersection under snow and ice condition with the method of computation and simulation,the computed result shows that the traveling capability is only 63%~66% and 46%~52% of normal under ice and snow condition.The simulation result also indicates that under the snow and ice condition,the average velocity reduced greatly on one hand,the travel time and queue length as well as average delay increased greatly on the other hand. |
