PSA stands for Public Service Announcement. All levels of government could do a whole lot better in continuing education for the masses. Case in point are the roundabouts that are being mandated by the DOT and meeting heavy resistance from many of the people. I'm finding more of them in the Chicago suburban area and theirs differ from most in that they have a stop sign at the entrance to give people a moment to observe traffic and plan their route. While one of the reasons for a roundabout is to eliminate stop signs, it is a worthwhile consideration and the stop sign can be removed and replaced with a Yield sign in due time.
Colorado has heavy use of them especially along Interstate 70 through the mountains and into ski resorts. Once I encountered three roundabouts connecting each other while exiting the interstate and looking to take a break. See them here. They do work. However, they are not intuitive and there is a learning curve. Stop signs at the entrance is part of that but a public education program is needed across the state to teach people both the history of roundabouts, why they are being incorporated within the state and how to maneuver through them. I got my first encounter with them in Colorado. It was a bit unnerving but I quickly got the idea.
The DOT needs to get the message out about how to handle yourself in a roundabout. Newspapers, radio and especially television must cooperate with the DOT for the benefit of everyone.
