【摘要】:通過對流出角功能的研究,以行車不發(fā)生側(cè)向滑移、側(cè)向傾覆為前提,以駕駛員能夠順利操作和感受為依據(jù),以不同路況為主要影響因素,通過建立模型,從理論上計算出了減速車道流出角,建立了不同設(shè)計速度、不同路況與對應(yīng)流出角之間的關(guān)系,為今后的流出角設(shè)計,特別是為積雪冰凍地區(qū)流出角設(shè)計提供了必要的理論依據(jù)。
[Abstract]:Through the study of the function of outflow angle, based on the premise that there is no lateral slip and lateral overturning, based on the smooth operation and feeling of the driver, and taking different road conditions as the main influencing factors, the model is established. The outflow angle of deceleration lane is calculated theoretically, and the relationship between different design speed, different road conditions and corresponding outflow angle is established, which is designed for the future outflow angle. In particular, it provides a necessary theoretical basis for the design of outflow angle in snow-frozen areas.
