Gary, I don't know. I don't have the answers, and don't claim to! I think in the eyes of the people running the show, they see two way as being more functional. Otherwise, i don't think would be any reason for them to change it. Your points about all the cars coming from one direction is true. It's easier for people to cross the street when they only have to worry about cars coming from one way. Plus, if all the cars are coming from the one way, if one car stopes to let someone pass, most likely the other cars will stop too. Unlike with two way, you have to wonder if the cars coming from the other direction will stop too!
