Information Flow Definitions

current infrastructure restrictions  (Existing)  

Restrictions levied on transportation asset usage based on infrastructure design, surveys, tests, or analyses. This includes standard facility design height, width, and weight restrictions, special restrictions such as spring weight restrictions, and temporary facility restrictions that are imposed during maintenance and construction.

incident information for public  (Existing)  

Report of current desensitized incident information prepared for public dissemination.

maint and constr work plans  (Existing)  

Future construction and maintenance work schedules and activities including anticipated closures with anticipated impact to the roadway, alternate routes, anticipated delays, closure times, and durations.
