The newly released Liberty Mutual Insurance Pedestrian Safety index ranks the top 15 safest U.S. cities for pedestrians in an effort to raise awareness and indentify best practices for keeping pedestrians safe.

The index is based on published government city statistics and residents' and commuters' perceptions of safety. Liberty Mutual surveyed 2,500 adult consumers in 25 cities.

According to survey respondents, adequate traffic signs, high visibility crosswalks, adequate signal time to cross streets, and street lighting are some of the biggest factors for pedestrian safety. Liberty Mutual found the safest cities at the top of the index rankings have made these safety features a priority, helping to reduce the number of pedestrian fatalities in the city.
