| 摘要: |
| 针对已有交通信号控制方法难以有效疏导拥挤交通流的现状,以感应线圈检测器采集到的实时数据为拥挤识别的基础,以拥挤流向放行车辆数最大为目标,提出了一种无信号周期、无固定相位相序限制的单个交叉口自组织信号控制的基本原理,研究了候选信号相位集、各流向权重、等待时间上限的确定方法,设计了局部拥挤条件下单个交叉口的自组织信号配时方法,并以VISSIM为工具进行了模拟验证和对比分析.结果表明,所提出的方法能够改善局部交通拥挤的疏导效果. |

| Abstract: |
| Aimed at the congestion evacuating,an available self-organizing signal control principle whithout signal cycle and fixed phase as well as phase order is proposed.The designed signal control method is based on inductive loop data to identify the congestion flow and will overcome the deficiency of the present signal control mode for controlling congested traffic flow.For maximizing the number of passing vehicles,the proposed signal control method includes some key components such as setting stand-by phases,weighting each stream,deciding the maximum waiting time and allocating signal timing.The method is tested and compared through simulation with VISSIM.The comparative analysis shows that the proposed method can evacuate the congested traffic flow of a congested intersection more effectively. |
