  1. "1_Q5" indicates the length of road segments classified as most critical for only a single assessment; "2_Q5" indicates the length of road segments classified as most critical from two assessments; "3_Q5" indicates the length of road segments classified as most critical from three assessments; "4_Q5" indicates the length of road segments classified as most critical from all four assessments performed. Values are given in both meters and percent of total road network for each type
