The invention belongs to the field of urban traffic control, and provides an urban traffic supersaturated region boundary control method and system. The method specifically comprises the following steps: S1, acquiring vehicle data of a controlled supersaturated area, and establishing a supersaturated urban traffic area model; and S2, based on the supersaturated urban traffic area model and an input-output feedback linearization theory, obtaining an optimal input traffic volume. Compared with an existing linearization boundary control technical scheme, the boundary control algorithm belongs to a global linearization algorithm, potential system performance divergence can be avoided, the traffic state of a controlled supersaturation area can be adjusted to an expected state more quickly and smoothly, and the traffic control efficiency is improved. The method is superior to a PI boundary control algorithm in terms of two indexes of road network accumulated space average traffic flow and vehicle average speed, can be easily expanded to road network boundary control of multiple macroscopic basic map subareas, and can effectively relieve traffic jam in a supersaturated urban area.
本发明属于城市交通控制领域，提供了一种城市交通过饱和区域边界控制方法及系统。所述方法具体为：S1获取所控过饱和区域的车辆数据，建立过饱和城市交通区域模型；S2基于所述过饱和城市交通区域模型和输入‑输出反馈线性化理论，得到最佳输入交通量。本发明与现有的线性化边界控制技术方案不同的是，所述边界控制算法属于全局线性化算法，能够避免潜在的系统性能发散，能够更快更平滑地调节所控过饱和区域的交通状态到所期望的状态，且在路网累积空间平均交通流量和车辆平均速度两个指标上面，表现优于PI边界控制算法，可以很容易地扩展到多宏观基本图子区的路网边界控制中，可有效缓解过饱和城市区域的交通拥堵。
