TxDOT Climbing Passing Lane

A climbing lane is an "extra" lane used for short distances in certain areas to improve safety, ease congestion and prevent delays. These lanes help facilitate the passing of trucks and slow moving vehicles whose speed drops because of the sustained steep grades. This data is updated by GRID users. Climbing passing lanes are located geographically along roadways using linear referencing.

爬坡车道（climbing lane）是在特定区域内短距离设置的“额外”车道，旨在提升道路安全水平、缓解交通拥堵并避免通行延误。此类车道可辅助因持续陡坡导致车速降低的重型货车及慢速车辆完成超车作业。本数据集由GRID用户更新维护。爬坡超车车道通过线性参照系统沿道路完成地理定位。更新频率：每年一次，数据来源：地理空间道路清单数据库（Geospatial Roadway Inventory Database，GRID）。更新频率：1年，数据来源：地理空间道路清单数据库（GRID）。安全级别：公开，所有权归属德克萨斯州运输部（TxDOT）：属实。相关链接：数据字典PDF [生成于2025/04/23]
