Highway Quality in Colorado 2018

Highway Quality in Colorado 2018

Highway segments and the various quality assurance data along with the overall grade, from the 2018 review of the Colorado Department of Transportation (CDOT).

Columns

NameSocrata field nameColumn name in sgr mountData typeDescription
HwyhwyhwyTextA Unique (3 Number - 1 Letter) Highway Identification Code or Designating for a State Highway, Business Route, U.S. Route or Tolled Facility. Odd numbers typically run North and South and Even numbers typically Run East and West.
DirdirdirNumberTraffic flow direction
BMPbmpbmpNumberBeginning milepoint
EmpempempNumberEnding milepoint
LengthlengthlengthNumberLength of highway segment (in miles)
RegionregionregionNumberA Domained Value Element (Region: 1-6) used to identify the Engineering Region number in which the Road Segment is located.
YearyearyearNumberYear finished
Fun_Clfun_clfun_clNumberIndicates the functional category and usage limitations of the segment of road, as defined by FHWA, and is broken down between rural and urban areas.
CountycountycountyTextName of the county the road segment lies in
P_Typp_typp_typNumberPavement Type Classifications: 1 - Asphalt, 2 - Asphalt over concrete, 3 - Concrete, 4 - Concrete over asphalt
Traf_Ztraf_ztraf_zNumberTraffic Classifications: 1 - Low (<0.3 million design equivalent single access load ESAL), 2 - Medium (0.3 - 3 million ESAL), 3 - High (3 - 10 million ESAL), 4 - Very High (10 - 30 million ESAL), 5 - Very Very High (> 30 million ESAL)
Env_Zenv_zenv_zNumberClimate Classifications: 1 - Very cool (< 81 degrees), 2 - Cool (81 - 88), 3 - Moderate (88 - 97), 4 - Hot (>97)
DepthdepthdepthNumberThickness Classifications: 1 - Asphalt <4" thick or Concrete <8" thick, 2 - Asphalt <6" thick or Concrete >=8" thick, 3 - Asphalt >= 6" thick
Num_Lanesnum_lanesnum_lanesNumberNumber of lanes in the road segment
P_Grpp_grpp_grpNumberPavement group, which is a combination of the pavement, traffic, and climate classifications. 1323 means Asphalt, High Traffic, Cool Environment, >= 6" Thick
NhsnhsnhsNumberA Domained Value Element (NHSDesig: 0-9) used to identify whether the Road Segment is designated as being part of the National Highway System. Also contains the text value (added at the end)
IriiriiriNumberInternational roughness index (IRI) correlates somewhat with human exposure to whole-body vibration in vehicles and thus to perceived ride quality reading for the surface condition in the Primary Direction of Travel. Scaled to a score of 1-100.
RutrutrutNumberA value between 0 and 100 that is used to calculate Remaining Service Life for rutting. A value of 100 indicates .15 inch or less rutting. A value of 50 is the threshold that indicates no more remaining service life. This occurs at an average rut depth of .55 inches.
FatgfatgfatgNumberThe amount of fatigue normalized on a scale of 0-100 (where 0 is the worst pavement in existence and 100 is a perfect pavement)
TrantrantranNumberThe amount of transverse cracking normalized on a scale of 0-100 (where 0 is the worst pavement in existence and 100 is a perfect pavement)
LonglonglongNumberThe amount of logitudinal cracking normalized on a scale of 0-100 (where 0 is the worst pavement in existence and 100 is a perfect pavement)
CrbkcrbkcrbkNumberThe amount of corner breaks normalized on a scale of 0-100 (where 0 is the worst pavement in existence and 100 is a perfect pavement)
DLdldlNumberThe drivability life, which is the number of years a pavement has left until it is no longer an acceptable driving surface
