摘　　要：根据城市交叉口交通流的特点,给出了一种交叉口多相位自适应控制算法,综合考虑相邻车道上的车队长度,利用多层BP神经网络实现了道路交叉口多相位模糊控制.仿真结果表明,文中所设计的模糊神经网络控制器能有效地减少单交叉口平均车辆延误,具有较强的学习和泛化能力,是实现交通系统智能控制的一条新途径.According to the features of traffic flow in urban intersections, a multi-phase self-adaptive control algorithm was proposed. Multi-layer BP neural network was used to realize the multi-phase fuzzy control in road intersections by taking the queue length on contiguous phase lanes into account. Simulation results show that, as a new method of the intelligent control of traffic system, the proposed fuzzy neural network controller can decrease the average vehicle delay in single intersections and it possesses excellent learning and generating abilities.
