Gary Lauder on the Social and Environmental Impact of Stop Signs and Roundabouts (Video)


Suggests New "Take Turns" Sign
In this short video (4.27 mins), Gary Lauder makes a convincing case for better road design to help burn less fuel, save time, and save lives. He does the math for a simple "T" intersection that has three stop signs instead of one, and it turns out that it's an amazingly wasteful design (just imagine how many of those there is around the world!). Some of the conclusions: A new type of sign is needed to tell drivers to "take turns" when someone is already at the intersection, and roundabouts are much more efficient and safer than regular intersections.
