摘　　要：针对目前城市交叉口溢流状况频发且无有效控制的问题,提出了一种基于地磁检测的交叉口频发溢流识别与控制策略。首先,利用地磁检测器提供的检测数据,设计频发溢流检测指标。其次,构建优先放行非溢流方向交通流的控制模型,使得交叉口在未发生死锁的前提下,非溢流方向车辆的路权得到保证。最后,利用北京市昌平区某试验交叉口进行检测器布设和方法验证。结果表明,所提方法能够准确检测溢流发生且能抑制和消除溢流情况。To figure out solutions to the currently frequent overflow at urban intersections and the lack of effective control,this paper puts forward a strategy to identify and control this problem based on geomagnetic detection.First,frequent overflow detection indicators are designed on the basis of detection data provided by the geomagnetic detector.Second,a control model is built which prioritizes the traffic flow in the non-overflow direction so that the intersection does not overflow in the direction free from deadlock.Finally,a test intersection in Changping district of Beijing is selected to lay out detectors and verify the method.The results show that the proposed method can accurately detect,curb and even eliminate the overflow.
