This is especially important in Tucson. While the city itself is known for being bicycle-friendly, the state of Arizona actually has the fourth highest cycling fatality rate in the United States. According to a study of federal transportation data obtained by USA Today, Arizona had by far the worst death rate in the United States for bicycling accidents, with 6.5 fatalities for every 100,000 people. In addition, three of the four most dangerous cities for red-light running fatalities are located in the state of Arizona. Phoenix had the largest number out of all urban areas, followed by Memphis, Mesa, and Tucson.
