【摘要】 为了较准确地估计山区弯道路段随景观改变而改变的驾驶员行车视距的大小,本文在分析山区公路弯道路段道路线形、景观属性、车辆运行特征等的关系后,在一定的假设基础上将视距计算问题简化。根据各参数的几何关系建立了受山区弯道公路景观影响的行车视距估算模型,为山区弯道行车安全性评价提供了理论参考。更多还原

【Abstract】 In order to estimate the driver’s sight distance(SD),which changed with the landscape of crooked highway in mountain area,the relation of road alignment,landscape attributes and vehicle characteristics was analyzed,then the calculation of SD was simplified based on some assumption.According to the relations the SD estimation model affected by road landscape of crooked highway in mountain area was established.The SD model will act as a theory tool for assessing the safety of crooked road in mountain.更多还原
