The invention discloses a method for setting a free turning area based on a symmetrical-phase unbalanced traffic flow intersection, which comprises the following steps of: 1, setting a free turning area in front of an entrance lane stop line of a fixed direction area, i.e., on the side, facing an intersection, of the entrance lane stop line of the fixed direction area; and 2, establishing a control scheme of a fixed direction area entrance lane signal lamp set and a free turning area signal lamp set, wherein the fixed direction area entrance lane signal lamp set is used for indicating a vehicle control scheme behind the entrance lane stop line of the fixed direction area, the free turning area signal lamp set is used for indicating a vehicle control scheme of the free turning area. According to the invention, the entrance lanes of the free turning area are additionally arranged at the intersection, so that the number of vehicles passing through the intersection at each phase is increased in a permeable manner. More selectable routes are provided for vehicles at the intersection, the turning requirement of intersection traffic is met, the delay time of the intersection can be obviously shortened when the signal timing period of the intersection is long, the vehicles can enter the intersection in an orderly turning mode, and the traffic jam condition of a large-flow lane is effectively relieved.

    本发明公开的一种基于对称相位非均衡交通流交叉口设置自由变向区的方法,包括如下步骤:步骤一,在固定方向区进口道停车线前方,即固定方向区进口道停车线朝向交叉口的一侧设置自由变向区;步骤二,建立固定方向区进口道信号灯组和自由变向区信号灯组的控制方案;其中固定方向区进口道信号灯组用指示固定方向区进口道停车线后方的车辆控制方案;自由变向区信号灯组用于指示自由变向区的车辆控制方案。本发明通过在交叉口增加设置自由变向区进口道,渗透性的增加每个相位通过交叉口车辆的数量。为交叉口车辆提供更多可选路线,满足交叉口交通的变向需求,在交叉口信号配时周期较长时,可以明显减少交叉口延误时间,使车辆能够有序变向进入交叉口,有效疏导大流量车道交通拥堵情况。
