| 摘 要： | 介绍了一种在信号交叉口建立左转保护相位的新方法，确立了在许可左转运行状态下，保护相位和许可相位转换的阈值，基于交叉口交通优化的原则，根据大量的实测数据，利用多变量回归模型技术，建立了三种情况下的回归关系式，第一种情况考虑的是专用左转车道的运行，而另外两种情况考虑的是共用左转车道的运行，实例验算表明了从许可相到保护相转换阈值建立的可行性和可预测性。

| Abstract: | A new approach to developing transitional threshold from permissive to protected left-turn phase at signalized intersection. Based on intersection traffic operation at optimum efficiency, three kinds of scenario are developed with the multivariate regression technique in terms of a number of observed data. The first scenario involves exclusive left-turn lane operation while the other two scenario involve shared-lane operation. The computing result shows that the development of transitional threshold is reasonable and predictable. |
