Modifying or reconstructing roadways can be challenging and time consuming. Careful evaluation of road characteristics is the key to a solid investment in public safety. When a traffic safety issue is identified, changing the roadway — including traffic signals, signage, or the like — may appear to be the most direct solution. However, a close look at crash data and driver behavior often reveals that engineering is just one component of a complete traffic safety solution — a solution that includes education, enforcement, and emergency services.
