    摘要:

    作为长大纵坡路段重要的安全保障设施,紧急避险车道在国内应用广泛。但限于山区高速公路地形条件的限制,不可避免的将紧急避险车道设置于圆曲线处。本文采用UC-win Road 9.0 驾驶仿真平台,对设置于右转圆曲线的紧急避险车道的流出角与引道阈值进行研究。选择方向调整时间、最小转向半径、方向盘转角幅值、方向盘转角频率四个指标对16名驾驶员驶入避险车道的数据进行回归分析,确定各指标与圆曲线半径的定量关系模型。然后通过二阶聚类的方法缩小了流出角度与引道的设置范围,最后考虑车辆的横向行驶稳定性,确定了避险车道的设置参数。建议将紧急避险车道设置于半径1000m及以上的主线处,流出角0°-5°,引道6s设计行程。条件困难时,紧急避险车道可设置于半径600m-1000m的曲线处,流出角0°-5°,引道为9s设计行程,流出角5°-10°,引道为12s设计行程。

    Abstract:

    As an important safety measurement for longitudinal steep slope, truck escape ramps are widely used in China. Limited to complex terrain of mountainous highway, truck escape ramps will be inevitably built in the horizontal curve. In this paper, UC-win Road 9.0 driving simulation was selected to study the departure angle and approach length of the truck escape ramps locating in the right-turning circular curve. Four indexes, adjusting time, minimum turning radius, steering wheel angle amplitude and frequency, were selected and analyzed by regression analysis using the data of 16 drivers entering the truck escape ramps. Then the quantitative model of each index with the circular curve radius and the departure angle was established. Through the second order clustering method, the setting range of the departure angle and approach length was narrowed. Finally, considering the lateral stability of errant vehicle, the design parameters of truck escape ramps were determined. It was recommended to set truck escape ramps at the main line with radius no less than 1000m, and the departure angle was 0°-5° while the approach length was 6s design speed travelling length. With the restricted condition, the truck escape ramps could be set at the horizontal curve radius of 600m-1000m, and the departure angle was 0°-5° while the approach length was 9s design speed travelling distance. The departure angle was 5 °-10 ° and the approach length was 12s design speed travelling distance.
