The invention aims to provide a road traffic node road section driving adaptability evaluation method for automatic driving, and the method comprises the steps: building a sight line database which maps the effective sight line distance of an automatic driving vehicle through obtaining automatic driving sight line related information and road traffic node design information; and further calculating an automatic driving available sight distance set in the road traffic node area and a corresponding maximum automatic driving speed for preventing sight distance failure, and calculating the driving adaptability of the road traffic node section according to a speed coordination evaluation method. The method can effectively evaluate the driving adaptability of the automatic driving vehicle at the road traffic node section, discriminates the driving risk position with insufficient sight distance, and provides an effective technical means for checking the actual operation potential safety hazard of the automatic driving vehicle at the existing road traffic node section.
本发明的目的在于提供一种面向自动驾驶的道路交通节点路段行驶适应性评价方法,通过获取自动驾驶视距相关信息与道路交通节点设计信息,构建映射自动驾驶车有效视线距离的视线数据库,进一步计算道路交通节点区域内的自动驾驶可获取视距集合及其对应的防止视距失效的最大自动驾驶行驶速度,根据速度协调性评价方法计算道路交通节点路段行驶适应性。本发明能够有效评价自动驾驶车在道路交通节点路段的行驶适应性,甄别视距不足的行驶风险位置,为自动驾驶车在既有道路交通节点路段的实际运营安全隐患排查提供有效技术手段。
