About the research
Speeding contributes to around 31% of fatal crashes. As a result, agencies rely on speed management countermeasures to reduce crashes and improve quality of life for residents around facilities where speeding is an issue. Several speed management toolboxes exist. However, most are focused on countermeasures for lower speed urban facilities. Iowa is characterized by a much wider range of speed issues, including rural communities, rural roadways, suburban, and high-to-low speed transition areas. A number of studies have been conducted to assess the impact of different countermeasures for these facilities (including a number conducted in Iowa). However, the information is not summarized in a format that is easily accessed. As a result, a toolbox is needed which provides a “one stop shop” for Iowa agencies interested in conducting speed management.
