| 摘 要： | 针对“潮汐式”交通问题，探讨可变车道的实施流程和转换机理．基于BPR路阻函数建立了可变车道调整数量优化模型。该模型不仅能根据交通流状况计算出需要调整的车道数．而且可以针对不同的道路条件计算出可变车道适合的转换时机。最后，通过实例验证了模型的可行性。

| Abstract: | According to tide traffic, it studies the implementing process and conversion mechanism of re- versible lane. Based on BPR function, it establishes the optimization model of adjusting the number of reversible lanes, which Can not only calculate the number of the lanes needing adjusting, but also can obtain the conversion time according to road condition. Finally, the model is verified by an example. |
