    Research on the Length of Acceleration Lane at Freeway Interchange

      摘要
    • 摘要: 为了避免高速公路加速车道长度不足引发的交通事故,从传统的高速公路加速车道计算方法入手,对各计算参数的取值进行了范围界定.在此基础上考虑到道路条件和交通条件对加速车道长度计算的影响,基于主线和匝道纵坡的影响进行了纵坡修正,参照无信号交叉口次要道路平均延误进行了主线交通量修正,使得高速公路加速车道长度的计算方法与实际情况趋于吻合.

       

      Abstract: There is a hidden danger with the shortage of acceleration lane length at freeway interchange.In order to drive sately,the paper consults the traditional method of calculating the length of acceleration lane, and limits the scope of each calculation parameter.Base on above calcolations.An analysis of the effect of road and traffic conditions to acceleration lane length is made the paper presents a new formula in order to adjust the length in theory to meet the demand in practice through the amended vertical slop and traffic volume of main lanes.
