The invention discloses an optimal signal phase design method for a single intersection based on a flow rate ratio. The optimal signal phase design method comprises three steps: a step S1, a step S2 and a step S3. The method comprises the following steps: S1, modeling intersection traffic flows based on intersection traffic data, and determining a compatibility graph Gc and a compatibility relation matrix Mc between the traffic flows according to the motion trail of the traffic flows; s2, determining a set phi of all signal lamp groups in the Gc; and S3, searching the set phi, and then determining an optimal signal phase scheme of the intersection based on the flow rate ratio.

    本发明公开了一种基于流率比的单个交叉口最佳信号相位设计方法,包括3个步骤:步骤S1、步骤S2和步骤S3。步骤S1先基于交叉口交通数据模型化交叉口交通流,继而根据交通流的运动轨迹确定交通流之间的兼容性图Gc和兼容性关系矩阵Mc;步骤S2确定Gc中所有信号灯组的集合φ;步骤S3搜索集合φ,然后基于流率比确定交叉口的最佳信号相位方案。
