Data DescriptionSingle RowHighway route, curvature, gradation, location, constructed year, inspection year, and quality measuresCollection ModeNot specifiedLong DescriptionThis dataset contains roadway sections in the State’s Sample Panel that are under CDOT’s jurisdiction. The Sample Panel provides detailed statistical data on a randomly selected sample of roadway sections in the State’s public roadway inventory to meet Federal reporting requirements for the Highway Performance Monitoring System (HPMS). Fields describe roadway segments identified by beginning and ending measured points. Segments are characterized by thickness metrics for rigidity and flexibility, roadway curvatures and grades, a score for the feasibility for widening the roadway, types of obstacles relevant to widening, local route identification, sight distance, speed limits, designation of right or left turn lanes, signal type and length of green time, number of signals in the segment and a description of road terrain.
