Routes in the new housing style are increasingly popular, but can sometimes get messy. One way to facilitate route un-confusingism would be if Routes worked like a Group.
Once you join a group it could automatically add you to the route as a new member of the circuit. Currators could set make it necessary for streets to be reviewed before they are added if applicable. Another variation is the option for groups to have more than one route and you can pick which to join.
If you are on a route your street could have more than one street sign - one for friends and one for routes. Instead of selecting the bottom sign you would just select the route name. It could say something like Continue Such-n-such route, with alt-text of whose home street is next.
