单个周期变换车道功能的交叉口信号配时研究

摘要

Aiming at the problem that it still has uneven space-time resource utilization in single signal cycle, variable approach lane in single signal cycle is put forward.A phase of the rest of the time is transferred to another phase flexibly, and the utilization efficiency of the intersection of time and space resources are improved.On the basis of the conventional design method of signal timing,and the traffic signal timing optimization design method of "Traffic technology" is put forward,and then case analysis was carried out on real intersection.The results show that "Traffic technology" can effectively realize the intersection of time and space resources optimization allocation, the intersection queue length and average delay are reduced, and improve the efficiency of intersection traffic is improved.%针对交叉口在单个信号周期内仍存在时、空资源利用率不均的问题,提出单个信号周期内变换车道转向功能的通行技术.将某一相位剩余的时、空资源灵活利用至另一相位中,以提高交叉口的时、空资源利用效率.在常规信号配时设计方法的基础上,进一步提出通行技术信号配时优化设计方法,并结合实际交叉口进行案例分析.研究结果表明:"通行技术"可有效实现交叉口时、空资源优化配置,减少交叉口排队长度和平均延误,提高交叉口通行效率.
