The current legally required two-year inspection interval for most bridges is not an efficient system for conducting inspections, because many bridges do not require inspections this frequently, while others would benefit from more frequent monitoring. The research presented herein is based on the premise...

Maintenance management has relied heavily on collecting asset condition information to plan maintenance activities and budget allocation. Data collection is often conducted on a sampling basis because of resource constraints. There is thus a perceived need for the development of an effective sampling...

National Bridge Inspection Standards do not require documenting damage location during an inspection but bridge evaluation provisions highlight the importance of location to determining the structural impact of damage. Capturing damage location information using current inspection and documentation methods...

Transportation agencies use a variety of methods to evaluate the condition of pavements and the characteristics of their use. Methods range from in-pavement sensors to ride quality characterizations that require specially instrumented probe vehicles. However, the extensive labor, specialized training...

Livability is a fairly new concept well understood in urban areas, but less so in rural areas and Indian reservations.

While this has improved the efficiency and financial viability of rail carriers, it has adversely affected...
