OSM 路网解析 Python 库

1 2 个路网优化库

1.1 Python 库：OSMnx

• 简介

  • 将 OSM 路网优化为 NetworkX 中的 Graph

  • 官网

• 建议

  • 先使用 osmosis 工具从原始 OSM 文件中提取路网标签，即：highway=*

  • 注意：OSMnx 库遇到缺失点会报错

预设路网过滤条件

提取路网的 6 种设置（site）

• 'drive'

["highway"]
["area"!~"yes"]
["access"!~"private"]
["highway"!~"abandoned|bridleway|bus_guideway|construction|corridor|cycleway|elevator|escalator|footway|path|pedestrian|planned|platform|proposed|raceway|service|steps|track"]
["motor_vehicle"!~"no"]
["motorcar"!~"no"]
["service"!~"alley|driveway|emergency_access|parking|parking_aisle|private"]

% by Osmosis command
--tf accept-ways highway=* ^
--tf reject-ways area=yes ^
--tf reject-ways access=private ^
--tf reject-ways highway=bandoned,bridleway,bus_guideway,construction,corridor,cycleway,elevator,escalator,footway,path,pedestrian,planned,platform,proposed,raceway,service,steps,track ^
--tf reject-ways motor_vehicle=no ^
--tf reject-ways motorcar=no ^
--tf reject-ways service=alley,driveway,emergency_access,parking,parking_aisle,private ^

• 'drive_service'

["highway"]
["area"!~"yes"]
["access"!~"private"]
["highway"!~"abandoned|bridleway|bus_guideway|construction|corridor|cycleway|elevator|escalator|footway|path|pedestrian|planned|platform|proposed|raceway|steps|track"]
["motor_vehicle"!~"no"]
["motorcar"!~"no"]
["service"!~"emergency_access|parking|parking_aisle|private"]'

• 'walk'

["highway"]
["area"!~"yes"]
["access"!~"private"]["highway"!~"abandoned|bus_guideway|construction|cycleway|motor|planned|platform|proposed|raceway"]["foot"!~"no"]
["service"!~"private"]',

• 'bike'

["highway"]
["area"!~"yes"]
["access"!~"private"]
["highway"!~"abandoned|bus_guideway|construction|corridor|elevator|escalator|footway|motor|planned|platform|proposed|raceway|steps"]
["bicycle"!~"no"]
["service"!~"private"]

• 'all'

["highway"]
["area"!~"yes"]
["access"!~"private"]
["highway"!~"abandoned|construction|planned|platform|proposed|raceway"]
["service"!~"private"]

• 'all_private'

["highway"]
["area"!~"yes"]
["highway"!~"abandoned|construction|planned|platform|proposed|raceway"]
