The study says that increasing the road speed limit to improve congestion is not obvious, but increases the risk of accidents.

CTOnews.com, July 15, at least eight states in the United States plan to increase road speed limits this year, hoping to improve road congestion. However, according to the latest survey data released by the American Automobile Association, raising the speed limit is limited to improve congestion, but will significantly increase traffic accidents.

The American Automobile Association found a significant positive correlation between higher speed limits and crashes on two interstate highways, and data show that lowering the speed limit can also curb crashes.

Citing the foundation, CTOnews.com found that there was little change in the time it takes for drivers to cross the road, whether raising or lowering the speed limit.

Jennifer Ryan, director of national relations at the American Automobile Association, said:

At least eight state legislatures have raised speed limits this year. But the benefits are overestimated and the risks are underestimated. Raising the speed limit does not always produce the positive results that traffic planners envision.
