摘要
《公路路线设计规范》(JTG D20—2017)对互通立交减速车道长度做出了规定,但实际交通环境复杂,各种因素都会对换道行为产生影响。因此,对减速车道长度进行更为全面的研究是降低高速公路出口事故率的基础。通过分析各国减速车道长度的相关标准,明确减速车道长度的计算过程,对其影响因素进行讨论,建立考虑多种影响因素的减速车道长度计算模型,进而为规范中减速车道长度的完善提供参考。
Although the Design Specification for Highway Alignment(JTG D20—2017)has specified the length of the interchange deceleration lane,since the actual traffic situation is complex and various factors would affect the lane change behavior,comprehensively studying the length of the deceleration lane is fundamental to reducing the accident rate at the exit of the expressway.In this paper,by analyzing the specification of the length of the deceleration lane in each country,the calculation process was determined and influences were discussed.The calculation model for the length of the deceleration lane considering various influencing factors was established,providing a reference for improving the specification's length of the deceleration lane.
