Why is this important?

Transportation-related crashes cause personal tragedy, congestion, and loss of productivity while contributing to rising health care costs. Traffic crashes are the leading cause of death among people from age one to 34.[i] The safety of our region’s transportation system is especially important for bicyclists and pedestrians, on whom the impacts of crashes are generally greater than on other users of the system. Moreover, perceptions of safety can influence the extent to which individuals choose to bike or walk.[ii]
