延误是交叉口交通设计和信号优化的重要评价指标。针对传统延误计算仅考虑单个交叉口的不足，本文构建了综合考虑上下游交叉口交通运行参数的延误计算模型。模型以交通波理论为基础，综合考虑了上下游交叉口的相位相序、绿灯时长、流向流量、路段长度及相位差等因素，通过计算下游交叉口队尾时空点在各相位的演变构建队尾时空多边形，计算队尾时空多边形的面积即可得到下游交叉口计算车道组的停车延误，将其加上加减速延误最终得到交叉口信号控制延误。示例分析表明，该模型与VISSIM和SYNCHRO等软件相比，延误计算精度较高。

Intersection delay is an important evaluation index for traffic design and signal optimization. To overcome the demerit that the traditional delay calculation method considers about the isolated intersection, a new delay model is built by taking into the up-stream and down-stream intersections considerations. The model is based on the traffic-wave theory, and it synthesized analyzes the main influential parameters of up-stream and down-stream intersections, such as phases, splits, movement volume, link length, offset, etc. A polygon formed by spatiotemporal coordinates of the queues rears is constructed by capturing the evolution of queue phase by phase, which area is used to calculate the stop delay of the object lane-group of down-stream intersection. The intersection signal control delay can be counted by adding stop delay and acceleration-deceleration delay. Through a case study comparing with VISSIM and SYNCHRO software, it is found that the model is reliable for intersection delay.
