摘要
文中详细分析了拓宽路口的车辆驶出率,应用路口拓宽条件下车辆累计到达—离开图给出了拓宽交叉口的均匀延误计算公式,对传统的溢流延误模型进行了修正,进而提出了拓宽交叉口平均延误的计算模型。
Widening approach is an efficient measure to improve running condition and increase capacity of intersections.However,there are few analyses on traffic flow of widened intersection.The paper analyzes flow rate of widened intersection.A uniform delay calculation formula of widened intersection is presented through analyzing the cumulative arrival-departure diagram.A modification is conducted to classical overflow delay and the average delay model of widened intersection is put forward.
