高速公路车速限制实施方法研究

Implement method of speed limit on freeway

通过对分车型与分车道车速限制的优缺点及适用性进行综合分析,应用关于最高车速限制基准值、车道数及车道位置修正系数及最低车速限制方法的研究成果,给出了不同车道高速公路的分车型与分车道车速限制方法与建议值,提出了车速限制区间和车速限制连续性指数的概念,以车速限制连续性指数小于0.85作为车速限制区间的划分依据,给出了高速公路车速限制区间划分结果。

Based on analyzing merits and demerits and applicability of speed limit of different lanes and different vehicle types comprehensively,applying study results of author＇s about the maximum speed limit fiducial value,correction coefficients of the number and location of lanes and the minimum speed limit method,it were brought forward that implement methods and suggestion values of speed limit of different vehicle types and lane according to lane numbers.The concepts of speed limit zone and continuity index of speed limit was given.Taking the continuity index of speed limit being less than 0.85 as dividing basis of speed limits zone,division results of speed limit zone were given.
