VITAL SIGNS INDICATOR Highway Pavement Condition (T17) FULL MEASURE NAME Distressed share of highway lane-miles LAST UPDATED February 2017 DESCRIPTION Highway pavement condition, measured by the share of highway lane-miles flagged as “distressed” by Caltrans, reflects the regional pavement quality on the highway system. The dataset includes regional and road segment tables. DATA SOURCE California Department of Transportation: State of the Pavement Report http://www.dot.ca.gov/hq/maint/Pavement/Pavement_Program/PDF/2015_SOP-7-9_12-22-15-FINAL_revised_1-4-15.pdf CONTACT INFORMATION vitalsigns.info@mtc.ca.gov METHODOLOGY NOTES (across all datasets for this indicator) Caltrans datasets only include regional performance on a historical basis and rely on "distressed" lane-mileage as an indicator for poor pavement condition. The geospatial data for 2015 provides the condition on each lane-mile for each segment of roadway; data on a corridor basis reflects a sum of all lane-mileage for that corridor.
