摘要 研究了暴雨对不同车道数的城市快速路交通运行的影响.首先估算了暴雨下自由流车速、通行能力等关键参数下降幅度;然后利用最小二乘法标定了6种连续型速度—密度模型,最后评价了模型估计关键参数能力和预测车速能力.研究表明:暴雨下路段的自由流车速和通行能力下降幅度、模型估计关键参数能力和预测车速能力都随车道数不同而不同.因此有必要区分暴雨对不同车道数快速路路段的影响. This paper investigates the impacts of rainstorm condition on traffic operation of multi-lane urban expressways. Firstly, reductions in free-flow speed and capacity are calculated. Secondly, six one- regime speed-density models are calibrated by least square method. Finally, best models for key parameter estimation and for operating speed prediction are assessed. Results show that reductions in free-flow speed and capacity, and the abilities to estimate key parameter and to predict operating speed vary with different number of lanes under rainstorm condition. Therefore, it necessitates distinguishing rainstorm＇ s impacts on urban expressway segments with different number of lanes.
