William H. McLellan (road safety audit pioneer)

William H. McLellan was a key figure in developing the concept of road safety audits, systematic evaluations of roads to identify potential hazards and improve safety. His pioneering work helped formalize procedures for reviewing road designs, upgrades, and construction plans to prevent accidents before they happen. McLellan’s contributions transformed roadway safety practices, emphasizing proactive assessment rather than reactive measures, and have influenced transportation engineering worldwide. His efforts have helped create safer roads, protecting drivers, cyclists, and pedestrians through early identification and mitigation of safety risks.
