摘要

摘要: 为确定高速公路隧道路段大型车的运行速度特征点和运行速度值, 分析了高速公路隧道路段运行速度特性及规律, 通过跟车试验, 研究了不同长度隧道内驾驶人的行车规律和隧道路段的车速变化规律, 提出了隧道路段运行速度研究点, 通过特征点速度采集试验, 确定了隧道路段运行速度特征点, 建立了高速公路长大隧道特征点运行速度模型, 并对模型进行了验证。分析结果表明: 中短隧道对大型车运行速度影响不大; 隧道进口前200 m、进口、出口外100 m 3个点可作为长大隧道运行速度特征点; 运行速度模型的相对误差均在10%以内, 模型有效。

Abstract: In order to identify the characteristic points and operating speeds for trucks at expressway tunnel sections, the operating speed characteristics at tunnel sections were analyzed.According to car following tests, the driving behaviors and speed changes of trucks in varied length tunnels were studied, and the observation points at tunnel sections were identified.After speed observation, the characteristic points at tunnel sections were verified, the operating speed models for the characteristic points were achieved, and the validities of the models were verified.Analysis result shows that middle tunnel and short tunnel have little impacts on truck speed.200 m before tunnel entrance, entrance point and 100 m after exit are determined as three characteristic points of operating speed for long tunnel, the relative errors of the models are within 10%, so the models are valid.
