Daily Notes


During the duration of the CC1 Testing, daily trafficking notes were created. Daily notes were created to document the traffic testing within the NAPTF. The daily notes included general information regarding the testing parameters, loading conditions, completed passes, vehicle faults, instrumentation issues, and testing start and finish times.
