通过分析中国高速公路港湾式停车带设置形式和参数中存在的问题,结合高速公路车辆运行速度特点、车辆驶入和驶出港湾式停车带的轨迹特点和驾驶人心理特征,以港湾式停车带的安全性和功能性为基础,提出了带变速车道的港湾式停车带设置形式、港湾式停车带变速车道和停车区长度计算模型,并给出了不同设计速度、纵坡和硬路肩宽度情况下港湾式停车带的设计参数建议值。研究成果可为高速公路港湾式停车带的合理设计提供参考。
By analyzing the problems existing in the installation form and parameters of harbor bay belts in China Expressway and combining with the characteristics of expressway vehicle running speed, the track characteristics of driving in and out bay mooring belts and the psychological characteristics of drivers, Based on the safety and functionality of the system, this paper puts forward the design of harbor parking zone with variable speed lane, the calculation model of speed change lane and parking area length of harbor parking zone, and gives the design speed, longitudinal slope and hard shoulder width Lower bay parking zone design parameters recommended value. The research results can provide a reference for the reasonable design of freeway harbor bay belt.
