The invention discloses a high-precision map high-speed emergency lane generation method and system and a medium, and the method comprises the following steps: obtaining a right side lane outer side line of each road interval on each expressway and sorted right side lane outer side lines according to lane sideline information; according to the road information associated with the road outer side line information, performing shape cutting on the road outer side line to obtain a right side road outer side line associated with each road; acquiring a right side road outer side line correspondingly associated with each road interval of each road according to the right side road outer side line and the sequenced right side lane outer side lines; according to the right side lane outer side line and the right side road outer side line correspondingly associated with each road interval of each road, whether a high-speed emergency lane needs to be generated or not is judged; emergency lane information is automatically generated through high-precision map data, the accuracy of lane-level path planning and driving safety are improved, and meanwhile the workload of manually collecting and drawing emergency lanes is greatly reduced.
本发明公开了一种高精度地图高速应急车道生成方法、系统及介质,其方法包括以下步骤:根据车道边线信息,获取每条高速公路上每个道路区间的右侧车道外侧线及排序后的右侧车道外侧线;根据道路外侧线信息关联的道路信息,对道路外侧线进行形状切割,获取每条道路关联的右侧道路外侧线;根据右侧道路外侧线与排序后的右侧车道外侧线,获取每条道路的每个道路区间对应关联的右侧道路外侧线;根据每条道路的每个道路区间对应关联的右侧车道外侧线及右侧道路外侧线,判断是否需要生成高速应急车道;以实现高精度地图数据自动生成应急车道信息,提高车道级路径规划的准确性及行车安全性,同时大大减少人工采集绘制应急车道的作业量。
