Deficient Bridges and Safety Information

Looking at recent history, bridge failures kill around five people per year in the United States (US), and that is not insignificant. But there may be well over 2,500 people a year killed either on bridges, or going off bridges, or hitting abutments and piers on a road passing under a bridge. Many victims are pedestrians and bicyclists. Functional obsolescence or imperfect geometric design does not directly cause crashes but non-optimal designs may increase the chance of a crash and aggravate injuries once a crash has occurred. However, it is almost always road user behavior that is the primary factor behind a crash. Therefore, the intent of this project is to analyze crashes and look at how driver and pedestrian behavior--and thereby safety--can be influenced with information technology as well as how behavior can be influenced by changes to the geometric design. This project is primarily a safety project. However, badly designed bridges are frequently the Achilles heel in urban and suburban pedestrian and bicycle networks. Therefore, this project certainly has important implications in the creation of livable communities.
