‘Green routing’ can cut car emissions without significantly slowing travel time

In detailed, computer simulations of traffic in Upstate New York’s Buffalo Niagara region, UB researchers Adel Sadek and Liya Guo found that green routing could reduce overall emissions of carbon monoxide by 27 percent for area drivers, while increasing the length of trips by an average of just 11 percent. In many cases, simple changes yielded great gains.
