* a 20 percent overall reduction in travel time compared to similar intersections that use conventional traffic designs
* superstreet intersections experience an average of 46 percent fewer reported automobile collisions – and 63 percent fewer collisions that result in personal injury
US motor vehicle deaths by year
About 90-115 people die every day in vehicle crashes in the United States.
Worldwide an estimated 1.2 million people are killed in road crashes each year and as many as 50 million are injured. Projections indicate that these figures will increase by about 65% over the next 20 years unless there is new commitment to prevention.
There is the potential that widespread superstreet adoption would save several thousand lives per year in the USA and a few hundred thousand lives worldwide.
The paper is called Operational Effects of Signalized Superstreets in North Carolina.
Mythbusters showed that only using right turns saves gas
The MythBusters concluded that right turns were indeed more efficient in their test. While the route favoring right turns was a longer distance and took a longer amount of time, it used only 4.0 gallons of fuel compared to 6.8 gallons of fuel on the “control” route.
