National Highways Emergency Areas

A view of the Emergency areas are located up to every 1.5 miles along smart motorways and offer a ‘safe haven’ for stranded vehicles. Please note this dataset is a visual representation of the emergency areas owned by National Highways. The auto-generate field of “Shape Length” does not represent the physical length of the emergency area.本数据集可视化展示的应急停靠区域（Emergency areas）沿智能高速公路（smart motorways）每隔至多1.5英里布设一处，可为抛锚车辆提供"安全避风港"。请注意，本数据集仅为英国国家高速公路管理局（National Highways）所辖应急停靠区域的可视化呈现。自动生成的「形状长度（Shape Length）」字段，并不代表应急停靠区域的实际物理长度。
