合理的超车换道模型设计是提高高速公路路段运载能力的重要途径。本文在基于安全因素及左右均可变道的条件下先后对经典的基于流体动力学的换道模型进行优化。在基于安全因素的优化过程中,通行能力饱和度在接近0.9左右仍能提高约3.36%;在引入左右均可换道规则后,通行能力饱和度进一步提高了2.54%。随后的基于统计的模型有效性检验表明两个优化的模型置信度达95%以上。

Reasonable overtaking model design is an important way to improve the road capacity. In this paper, in consideration of safety and both sides can to change, we have improved the lane changing model that basing on fluid dynamics. In the optimization process based on safety factor, capacity satura-tion can still increase about 3.36%. When the two lane changing rulehas been introduced, the capacity saturation improvesabout 2.54%. The model effectiveness test based on statistics shows that the two opti-mization model confidence more than 95%.
