Actually if you read the entire article it addresses the fact that while UPS finds most left turns inefficient there are some instances where their routing software recommends a left turn.
- oneeyedpigeon 13y agobut the article claims a ratio of 9-1 in favour of right turns, whereas the comment you're replying to implies it's much less than that.
- fnordfnordfnord 13y agoCutting out left turn makes a bigger difference in cities where turns are more frequent and often require waiting due to oncoming traffic. It saves fuel for UPS, else and for everyone who isn't waiting in a lane blocked by a UPS truck that is waiting to turn left. Now if we can just get others to stop turning left (when it requires blocking a lane). Since not all routes are in cities with dense traffic, not all routes will get the same benefit.
