【摘要】 针对我国山区公路交通事故多发的现状,分析影响驾驶操作的路线相关因素,借鉴已有的研究成果,探讨了视距、横向力系数、横向加速度、超高等路线指标的安全取值,对基于预测的运行速度计算出以上路线指标进行检验以判定设计不合理路段,为设计完善及安全保障工作提供参考。在AutoCAD平台上利用ObjectARX等开发工具开发了山区公路路线安全评价系统,通过某山区高速公路路线安全评价实例,介绍了系统的工作流程。更多还原

【Abstract】 Based on the severe situation of black spots in mountainous highway,the factors of influencing the driver’s operation are analyzed.With the theory of running speed,the index system for evaluating safety probability is established.The unreasonable sections of highway can be judged through testing the visual range,sideway force coefficient,lateral acceleration,superelevation and so on,then suggestions can be offered to the highway design and administration departments.The mountainous highway safety evaluation system can be developed with the establishment of index system.The work flow of system was introduced by a example of mountainous highway safety evaluation.更多还原
