| 摘 要： | 为解决冰雪条件下的信号交叉口上游拥堵识别问题,提出基于研究临界消散车队长度值的拥堵识别方法. 该方法根据汽车行驶理论与拥堵区间车辆行驶特点,将拥堵临界车辆的行车过程分为加速、匀速和减速过程,通过分析的拥堵排队车辆通过交叉口的过程,建立不同冰雪路面信号交叉口拥堵识别模型. 通过不同条件下相关参数标定,计算上游路段拥堵临界位置. 利用哈尔滨市区一个交叉口的实际调查数据进行验证,证明该模型能很好与实际相契合.

| Abstract: | To identify the congestion of signalized intersection upstream in snow and ice conditions, a method based on the value of the critical dissipation queue length was proposed. According to car driving theory and vehicle driving characteristics in the congestion interval, driving process of the critical traffic congestion was divided into acceleration, uniform speed and deceleration processes. Congestion identification model at signalized intersection in condition of snow and ice was formulated based on analysis of passing process of queuing vehicles. Upstream congestion threshold was calculated with the calibration parameters under different situation. The model was verified using the actual survey data of an intersection in Harbin city, and show the good fitness of model results and traffic flow in practice. |
