通过分析同向分隔带开口处车辆行驶的特点,从行车安全角度考虑,提出了同向分隔带开口段车辆采用第1次变换车道、等待插入行驶、第2次变换车道的三阶段行驶模型;在此基础上推导出了多车道高速公路同向车道分隔带开口长度计算模型,并提出了在不同设计速度、分隔带宽度和超高情况下的开口长度建议值。
From the perspective of traffic safety, this paper proposes a three-phase driving model with the lane changing lane of the same direction and dividing the lane for the first time, waiting to be inserted and the lane changing for the second time by analyzing the characteristics of vehicle driving at the opening of the same direction dividing belt. On this basis, the calculation model of the opening length of the same lane of multi-lane expressway is deduced and the proposed values of the opening length under different design speed, width and height are proposed.
