摘要
从分流区实际驶出交通流的特点和需求出发,提出了基于车道变换的高速公路出口识别视距计算模型。计算模型中考虑了驾驶人从内侧车道识别到出口的反应时间,以及驾驶人一次换道需要的距离。结果表明:和《路线设计规范》相比,该计算模型明确了识别视距构成的驾驶行为意义,界定了识别视距的范围,推荐的最小识别视距具有唯一选择性。
A lane transformation-based sight distance calculation model for highway identification was proposed,along with the characteristics and demands of actual traffic flow in the diverging area.In the model,the reaction time of recognition from inner side lane to exit and the distance required by drivers to transform lanes once are considered.The results show that different from the Design Specification for Highway Alignment,the model defined the driving behavior meaning and ranges of decision sight distance.Nevertheless,the recommended minimum decision sight distance calculated by the model is of unique selectivity.
