Each tested CI contains the data collected at the CI for Signal Phase and Timing (SPaT) testing and the output reports from the SPaT validation tool (described in the 2024 Crash Avoidance Metrics Partnership (CAMP) 'Assessment of SPaT Accuracy to Support RLVW Application' report), as well as the data collected at the CI for MAP testing and the output reports from the MAP validation tool (described in the 2024 CAMP 'Assessing Node Point Accuracy in the SAE J2735 MAP Message' report). Each folder and file contains the locally assigned values for the intersection it is associated with: 7704, 7705, 7706, 7707, 7708, 7709, 7710, 7720. ---------------------------------------------------------------- TABLE OF CONTENTS ---------------------------------------------------------------- A.
