The Alberta rural addressing system was created between 1979 and 1981 in Strathcona County, Alberta to satisfy the demands of Canada Post. It improved rural wayfinding for residents, emergency services and mail delivery. == The system == During the 1870s, the Dominion Land Survey had parceled much of western Canada into nearly square townships, which are approximately in both the north–south and east–west extents. Townships are designated by their "township number" and "range number", for example "Township 52, Range 25". The rural address pinpoints the access to the property off a range road, which runs north-south, or a township road, which runs east-west. Township roads are numbered using the township number, the first road being 0 (zero) with increments increasing every . Township 51's first township road would therefore be numbered 510, its second township road (2 miles north) is numbered 512, etc. Range roads are numbered from the east boundary of the range, and increase as one moves west in a similar fashion. Range 21's first range road would therefore be numbered 210, its second numbered 211, etc. The property address is the access location onto a township road or a range road. Each mile is divided in 40 units that are wide. These units are numbered from 1 to 79 on the south side of township roads and on the east side of range roads. The opposite side of the roads are numbered 2 to 80. An example address of a property on Township Road 512, east of the intersection with Range Road 211, would be: 21133 Township Road 512. Multi-lot subdivisions are addressed similar to apartments in a city, with a street address and a unit number. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Alberta rural addressing system」の詳細全文を読む スポンサード リンク
