There are things that individual drivers can do to improve fuel efficiency, such as driving less aggressively, and at lower speeds. But there are also things that government can do to impose better fuel efficiency, by changing the roadways.
The changes include using roundabouts instead of intersections with traffic lights, lowering speed limits, and removing some stop signs. All of those could help drivers reduce gas consumption.
Ian Lockwood, traffic engineer and partner with Glatting Jackson, a Florida-based community-planning design firm, talks to Melissa Block about ways to cut gas consumption in the face of record gasoline prices.
