The invention provides an intersection signal control method considering truck starting and following delay, which comprises the following steps of: establishing a truck starting delay model by respectively analyzing truck starting delay in an under-saturation state and an over-saturation state; according to the mobile bottleneck theory and the truck following delay definition, establishing a truck following delay model; based on a truck starting delay model and a truck following delay model, considering truck starting delay and truck following delay factors on the basis of a traditional delay minimum signal period calculation model, and re-establishing a delay minimum signal period calculation model; and controlling the signal lamp of the intersection according to the delay minimum signal period calculation model. According to the invention, by using a delay minimum signal period calculation method, the average vehicle delay of the intersection is reduced, and the service level of the intersection is improved.
本发明提供了一种考虑货车启动及跟驰延误的交叉口信号控制方法,包括如下步骤:通过分别分析欠饱和状态和过饱和状态货车启动延误,建立货车启动延误模型;根据移动瓶颈理论和货车跟驰延误定义,建立货车跟驰延误模型;基于货车启动延误模型和货车跟驰延误模型,在传统延误最小信号周期计算模型的基础上,考虑货车启动延误和货车跟驰延误因素,重新建立延误最小信号周期计算模型;根据延误最小信号周期计算模型,控制交叉口的信号灯。本发明利用延误最小信号周期计算方法,降低该类交叉口的车均延误,提高交叉口服务水平。
