Ok, I'll bite. Why not simply hunt existing trails? When you find them you know the deer are already using them don't you?
well if you aint got alot of trees to choose from or if you want to attempt to force a deer to take a different path with a better tactical advantage for the hunter. But mostly folks doin it for hunting purposes and not traveling purposes are just tryin to create places to place stands maybe with a better prevailing wind direction or ease of acess. If you wanted to get real serious with it you could create your own bed to feed pattern so to speak clear an area in a way that it get ample sunlight let it grow up an get thick then find your easiest accessible edge and nearest point of acess to a food source that you have established and create a trail from bed to feed with stands posted at various strategic points. They do this quiet a bit actually in places like kansas and other states that produce large deer and lack easy huntable cover. I actually guided some gentlemen a few years back who had a company that did just this, i believe they called themselves Buckbeds. An you would pay them to come to your property and do just as ive described. Tho i dont know how it went for them.
