在保证公交优先的前提下，提高社会车辆在信号交叉口的行驶效益，实现车道通行能力的最大化，研究了1种城市道路交叉口间歇式公交专用道（intermittent bus lane ，IBL ）运行模式，在公交车辆通行不受干扰时允许社会车辆驶入公交车道。
通过设置预信号实时控制进口道的车辆类型，实现公交专用道的分时共享。
考虑信号协同和换道规则，建立3车道元胞自动机模型，采用改进的速度效益模型模拟公交专用道运行状态，引入换道压力模型模拟清空区域强制换道规则。
以车辆的平均速度、排队和延误时间等作为评价指标，验证交叉口间歇式公交专用道的设置效果。
研究结果表明：①相较于传统公交专用道，交通量未达到车道通行能力的50%时，IBL 模式下社会车辆平均延误时间和排队时间分别降低6.9%和4.9%，公交车辆平均速度提高3%，平均延误时间降低5%；②当交通量达到车道通行能力50%~80%时，社会车辆平均速度提高15%~37%，平均延误时间降低8%~20%，但是公交车辆平均速度降低3.4%，平均延误时间提高5.7%；③当交通量大于车道通行能力的80%时，社会车辆平均速度提高6.7%，平均延误时间降低5.8%，而公交车辆平均延误时间提高28.2%。
最后，选取实际道路交叉口作为应用案例验证IBL 的可行性。
结果表明，在平峰时段、中等交通量条件下，IBL 模式具有良好的适用性，可以显著降低排队时间。
