Cycling network

Cycling facilities identified according to their types (strip, track, greenway, mixed area, discontinuity, mixed carriageway, picto on carriageway) and their directions of circulation (two-way, two-way, one-way). The type of coating, the date of construction, the client and the status (existing or planned) are also provided. The sections were digitized from the aerial view 2011 and the attributes were filled in through field observations.本数据集涵盖按类型与通行方向分类的自行车交通设施：其中设施类型包括带状自行车道（strip）、专用自行车道（track）、绿道（greenway）、混合通行区域（mixed area）、间断段（discontinuity）、混合车道（mixed carriageway）及车道骑行标识（picto on carriageway）；通行方向分为双向（two-way）与单向（one-way）。此外，数据集同步收录了设施的路面涂层类型、建设日期、委托方及设施状态（现有或规划中）。所有设施路段均基于2011年航空影像完成数字化提取，其属性信息经实地观测补充完善。
