Every day, numerous vehicles traverse traffic bridges worldwide, contributing to the movement of goods, commuting, and fostering economic development. These bridges act as lifelines for cities, enabling smoother traffic flow and reducing congestion on busy roadways.
Even though the number of bridge related traffic accidents are decreasing, the consequences of bridge accidents can be devastating, causing injuries, loss of life, traffic disruptions, and substantial economic costs.
With narrow driving lanes and heavy, high-speed traffic, connecting overseas traffic bridges like the Great Belt Bridge, generally represent an increased risk of traffic accidents. When adding infrastructural elements like payment tolls, it adds another layer of navigational complexity and increases risk of accidents for drivers in both small and large size vehicles. Sudden change in weather, road conditions, road layouts (e.g., number of lanes), or information flows can cause spontaneous or indecisive traffic behavior. To ensure a high level of safety for small and large size vehicles crossing the Danish Great Belt Bridge, Sund & Baelt (the organization responsible for operating and maintaining the bridge and payment toll) launched a behavior change program optimizing traffic flow, minimize travel time, and mitigating risk of traffic accidents.
