Highway Quality in Colorado 2015
Highway segments and the various quality assurance data along with the overall grade, from the 2015 review of the Colorado Department of Transportation (CDOT).
Columns
| Name | Socrata field name | Column name in sgr mount | Data type | Description |
|---|---|---|---|---|
| tran | tran | tran | Number | The 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) |
| trafZ | trafz | trafz | Number | Traffic 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) |
| pTyp | ptyp | ptyp | Number | Pavement Type Classifications: 1 - Asphalt, 2 - Asphalt over concrete, 3 - Concrete, 4 - Concrete over asphalt |
| pGrp | pgrp | pgrp | Number | Pavement group, which is a combination of the pavement, traffic, and climate classifications. 1323 means Asphalt, High Traffic, Cool Environment, >= 6" Thick |
| mtcY | mtcy | mtcy | Number | For CDOT internal use |
| mtcD | mtcd | mtcd | Number | For CDOT internal use |
| long | long | long | Number | The 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) |
| iri | iri | iri | Number | International 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. |
| fatg | fatg | fatg | Number | The amount of fatigue normalized on a scale of 0-100 (where 0 is the worst pavement in existence and 100 is a perfect pavement) |
| envZ | envz | envz | Number | Climate Classifications: 1 - Very cool (< 81 degrees), 2 - Cool (81 - 88), 3 - Moderate (88 - 97), 4 - Hot (>97) |
| dlIdx | dlidx | dlidx | Text | For CDOT internal use |
| dl | dl | dl | Number | The drivability life, which is the number of years a pavement has left until it is no longer an acceptable driving surface |
| depth | depth | depth | Number | Thickness Classifications: 1 - Asphalt <4" thick or Concrete <8" thick, 2 - Asphalt <6" thick or Concrete >=8" thick, 3 - Asphalt >= 6" thick |
| curve | curve | curve | Text | For CDOT internal use |
| crbk | crbk | crbk | Number | The 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) |
| funCl | funcl | funcl | Number | Indicates the functional category and usage limitations of the segment of road, as defined by FHWA, and is broken down between rural and urban areas. |
| county | county | county | Text | Name of the county the road segment lies in |
| bmp | bmp | bmp | Number | Beginning milepoint |
| region | region | region | Number | A Domained Value Element (Region: 1-6) used to identify the Engineering Region number in which the Road Segment is located. |
| year | year | year | Number | Year finished |
| cond | cond | cond | Text | Condition of the road: LOW, MODERATE, HIGH |
| emp | emp | emp | Number | Ending milepoint |
| length | length | length | Number | Length of highway segment (in miles) |
| numLanes | numlanes | numlanes | Number | Number of lanes in the road segment |
| rut | rut | rut | Number | A 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. |
| nhs | nhs | nhs | Number | A 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) |
| hwy | hwy | hwy | Text | A 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. |
| dir | dir | dir | Number | Traffic flow direction |
