| 摘 要： | 针对双车道公路曲线路段碰撞事故高发的特点,选取某双车道公路5个简单平曲线,实测弯道路段车辆行驶轨迹,分析大货车、大客车、小货车和小客车等主要车型在上行、下行方向的轨迹中线偏移量,研究不同车型的行驶轨迹偏移特性.通过测定不同车型在不同半径平曲线行驶的轨迹交叉面积,建立车型、平曲线半径与行驶轨迹交叉面积关系模型,为双车道公... |
| 关 键 词： | 双车道公路 弯道路段 行驶轨迹 横向偏移 轨迹交叉面积 |

| Abstract: | Five simple curves are selected to survey vehicle running track because of the features of many collision accidents in two-lane highway curves.Based on the analysis of trajectory excursion about large trucks,buses,small trucks and small passenger cars in the upward and downward direction,the characteristics of vehicle lateral excursion of different types are researched.And the relationship is established among vehicle types,radius of curve and cross-area tracks by measuring cross-area tracks of different ra... |
| Keywords: | two-lane highway curl road driving track lateral excursion cross-area tracks |
