- Abstract:
- A capacity model of multi-phase signalized intersections is derived by a stopping-line method.It is simplified with two normal situations:one situation involves one straight lane and one left-turn lane;the other situation involves two straight lanes and one left-turn lane.The results show that the capacity is mainly relative to signal cycle length, phase length, intersection layout and following time.With regard to the vehicles arrival rates, the optimal model is derived based on each phase’s remaining time balance, and it is solved by Lagrange multipliers.Therefore, the calculation models of the optimal signal cycle length and phase lengths are derived and simplified.Compared to the existing models, the proposed model is more convenient and practical.Finally, a practical intersection is chosen and its signal cycles and phase lengths are calculated by the proposed model.
- 采用停车线法建立了多相位信号交叉口通行能力模型, 并对直行车道和左转车道均为一条以及直行车道为2条而左转车道为一条这2种常见状态下建立的模型进行了简化, 结果表明信号交叉口通行能力主要和信号周期长度、相位配置、交叉口几何设计和车辆跟车时距等因素有关.考虑车辆到达率时的信号周期长度和相位配时设置问题, 建立了基于各相位剩余时间均衡的优化模型, 并采用拉格朗日乘子法对优化模型进行求解, 从而确定出信号周期最佳时长以及各相位时长的计算模型, 并对模型进行了简化.所建立周期和相位时长的计算模型较现有的模型更简便实用.最后, 选取了一个实际的交叉口, 用所建立的模型对其周期和相位时长进行了设计.
