Complex Networks Perspectives towards Accelerated Bridge Construction

Accelerated Bridge Construction (ABC) advances the life cycle cost, reduces construction time, results in higher quality of elements and can create impacts on the road network carrying regular traffic. The problem may get escalated during major natural extreme events (hurricane, wildfire). As such, network positions or credentials of bridges based on their topography or connectivity need to be assessed to prioritize or stage ABC activities. There have been limited investigations from different state agencies to monitor the effects on traffic due to ABC related activities and to identify more efficient strategies to pursue such activities while reducing overall system-wide impact. This study emphasized on a coordinated and extensive network experiments at different geographic scales to apply complex network science principles to the study of bridge networks and ABC related activities. Geographic information systems (GIS) modeling is used along with Florida Department of Transportation (FDOT) bridge and road network data to run network experiments and prioritize certain bridges based on their network credentials. In particular, the study established a systematic approach to rank the topological credentials of bridges based on the connectivity of road networks. The research provides new insights into ABC activities based on the topography of vulnerable bridges and monitoring system-wide impacts during crisis such as emergency evacuations during major hurricanes. The study guides towards developing a credible tool that would benefit states, municipalities and other transportation authorities to prioritize risk based maintenance strategies and implement different ABC methods ensuring more efficient cost, schedule and quality.
