Speed Limits

This feature class contains unofficial speed limit data for all of the roadway segments within the City of London. Speed Limit data is provided for information purposes only. The final source of truth is the Traffic and Parking By-law and not this dataset. If the road segment doesn't have a speed limit, it is 50km/h.本要素类（feature class）收录伦敦市范围内所有道路路段的非官方限速数据。本数据集仅用于信息参考用途，最终的权威依据为《交通与停车地方法规》（Traffic and Parking By-law），而非本数据集本身。若某道路路段未标注限速，则默认限速为50km/h。
