The U.S. Road Assessment Program (USRAP) was established by the AAA Foundation for Traffic Safety to undertake a systematic assessment of American roadways. Controlled-access freeways provide the highest level of safety among road types; however, other road types deserve closer study to determine causes for crashes and solutions for improvement. Maps created by USRAP can help you identify routes that present a lower risk of crashes, plus those where caution should be observed when traveling.
