ESTABLISHING A LINK/NODE REFERENCING SYSTEM IN NORTH CAROLINA
M C Oppermann, S-S Wu · 1994
The state of North Carolina has historically managed highway-related data on a county/route/mile post system. Route changes due to new construction or redesignation of a route cause the mileposting of the route to change; therefore, tracking historical information over time is virtually impossible. A link/node referencing system was proposed to solve this problem by providing a stable designation over time. A node is assigned to each permanent physical feature on the road with links established as the distance between adjacent nodes. This system solved the problem because all data will be associated with a link or node and will not be dependent on the route designation and the mile post.
