The invention discloses an expressway exit ramp and connection intersection combined control method, which comprises the following steps of: 1, controlling connection intersection signals, 2, judging whether side road pre-signals are set or not and calculating green light duration, 3, calculating parking times and establishing a two-way optimization model, and 4, determining whether the side road pre-signals are set or not and calculating green light duration. 4, constructing a combined control model of the exit ramp and the joined intersection; 5, solving a target function by using an NSGA-II (Non-dominated Sorting Genetic Algorithm-II) algorithm; according to the invention, on the basis of the vehicle networking control of the expressway exit ramp and the ground connection area, the exit ramp is not controlled, the pre-signal is arranged on the side road, and the NEMA double-loop phase control is adopted at the connection intersection, so that two traffic streams with conflicts are effectively prevented from being released at the same time, and the spatial safety of the intersection is ensured; meanwhile, timing is not limited to unification of time of two phases, more phase and timing schemes are provided, and space-time resources of the intersection are fully utilized.
本发明公开一种快速路出口匝道与衔接交叉口联合控制方法,步骤一、衔接交叉口信号的控制,步骤二、辅路预信号设置与否的判断和绿灯时长的计算,步骤三、停车次数的计算和双向优化模型的建立,步骤四、出口匝道与衔接交叉口联合控制模型的构建,步骤五、利用NSGA‑Ⅱ算法对目标函数求解;本发明在对快速路出口匝道与地面衔接区车联网控制的基础上,对出口匝道不进行控制,在辅路设置预信号,衔接交叉口采用NEMA双环相位控制,有效的避免了存在冲突的两股车流被同时放行,保证交叉口在空间上的安全,同时配时不局限于两个相位时间上的统一,提供更多相位和配时上的方案,充分利用交叉口的时空资源。
