【摘要】 为探究高速公路隧道出口至收费站最小间距的合理取值，分析对比了隧道出口至收费站间车辆驾驶行为，给出了最不利情况下的间距计算公式。通过引入可靠度理论，建立功能函数，分析了不同隧道出口至收费站间距、不同车道数同隧道出口至收费站间距可靠性之间的关系，并反算得到了不同设计速度下隧道出口至收费站间距推荐值。最后，通过VISSIM仿真研究了可靠性设计的合理性。结果表明：使用可靠度推荐值进行隧道出口至收费站最小间距设计，路段车辆平均速度提升8.6%～11.8%,交通冲突率下降19.1%～22.7%。表明研究成果能够改善隧道出口至收费站路段的交通流畅性与安全性，具有一定的现实意义。更多还原

【Abstract】 The reasonable value of the minimum distance from the exit of an expressway tunnel to the toll station was explored. The driving process from the tunnel exit to the toll station was analyzed, and the calculation formula for the distance under the worst conditions was provided. By introducing reliability theory and establishing the functional function, the relationship between the distance from the tunnel exit to the toll station and the reliability of this distance for different numbers of lanes was analyzed. The recommended value of the distance from the tunnel exit to the toll station under different design speeds was inversely calculated. Finally, the rationality of the reliability design was investigated through VISSIM simulation. The results indicate that the average speed of vehicles on the road section, designed with the recommended reliability value for the minimum distance from the tunnel exit to the toll station, is increased by 8.6% to 11.8%, and the traffic conflict rate is reduced by 19.1% to 22.7%. It was demonstrated that the research findings could enhance the traffic fluency and safety of the road section from the tunnel exit to the toll station, indicating certain practical significance.更多还原
