Instead of terrain type acting as a multiplier to your wilderness movement rate, like this (from BFRPG):What is a “movement point system”?
Characters are given movement points to spend, and terrain types cost different amounts to enter, like this (from the original D&D wilderness adventure supplement, Outdoor Survival):
Much easier to use when traveling through multiple types of terrain in the same day.
I'm not sure why D&D didn't hang on to movement points for handling outdoor travel. There seems to have been a strong reluctance post-OD&D to nail down a default map scale for wilderness adventures, even though that makes them much easier to create and run.
