Routing question

[wterryiv]

I have a question on how this thing chooses routes. I asked it the shortest route from my house to work and it gave me the route that I normally take to work, but when asked shortest route from work to the house, it doesn't just give me the reverse route, but an entirely different way home. I don't get it. It does the same thing when I ask it for directions from my house to my cousins house and then it gives me a different way home from his house. Bizzare.

This happens regularly. I've heard that the 'logic' it uses is to minimize left turns, thus making your journey safer.

Or it might 'think' that one (or several) streets is One Way.

I've heard that the 'logic' it uses is to minimize left turns, thus making your journey safer.

Logically, right turns are also usually quicker (and shorter) as you don't have to wait for oncoming traffic, as you may have to do with left turns.

Having said that , I don't know if TT uses this type of logic, but I wouldn't be surprised if they did.

It could also just be that the route truly is shorter, even if only by a couple of yards.
