How to Improve the Stop Sign?

Traffic author Tom Vanderbilt writes about the modern stop sign. Vanderbilt describes the stop sign’s origins, its failures, and a few proposed alternatives. One alternative (“Drivers Alert”) “attaches a secondary stop sign to the back of the stop sign across the intersection, giving the driver two chances to see the sign. It also graphically advises whether cross traffic is meant to stop or not.” Another alternative would read “Take Turns,” and tell drivers: “If cars are waiting please stop and alternate.” Readers, any ideas for making the stop sign more effective?
