Columns
| Name | Socrata field name | Column name in sgr mount | Data type | Description |
|---|---|---|---|---|
| the_geom | the_geom | the_geom | MultiLine | Auto generated field containing the geometry of each item. Users note that this field may or may not be completely accurate. It is recommended for the user to run a separate analysis. |
| ROUTE | route | route | 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. |
| REFPT | refpt | refpt | Number | A Linear Reference Number or Address Key (to the Thousandth of a Mile) Representing the Starting Point of a roadway segment. A Unique Landmark Location (not the running measure) or (maybe a one-time true measure) of a roadway segment along a State Route. |
| ENDREFPT | endrefpt | endrefpt | Number | A Linear Reference Number or Address Key (to the Thousandth of a Mile) Representing the Ending Point of a roadway Segment. A Unique Landmark Location (not the running measure) or (maybe a one-time true end measure) of a segment along a State Route. |
| RUNLENGTH_ | runlength_ | runlength_ | Number | |
| RUNLENGTH1 | runlength1 | runlength1 | Number | |
| LENGTH_ | length_ | length_ | Number | The Centerline Segment Length or Segment Distance (in Miles) to the Thousandth of a Mile. Length is the distance from one Road Segment to the next Road Segment. Length is a dimension or measurement that is carried out 3-decimal places. |
| UPDATEYR | updateyr | updateyr | Text | The last calendar year in which the data was updated. |
| COUNTSTATI | countstati | countstati | Text | |
| AADT | aadt | aadt | Number | The annual average daily traffic count for the segment. (Total of all vehicles counted in a year divided by 365 days) |
| AADTCOMB | aadtcomb | aadtcomb | Number | The AADT consisting of combination trucks (3 or more axles-single trailer or multiple trailers). |
| AADTDERIV | aadtderiv | aadtderiv | Text | A Domained Value Element (AADTDeriv) indicating the Code Associated with the Factoring Method used in calculating the AADT determination Value. |
| AADTSINGLE | aadtsingle | aadtsingle | Number | The AADT consisting of single unit trucks (vehicles larger than pickup trucks built on a single chassis). |
| AADTTRUCKS | aadttrucks | aadttrucks | Number | Annual Average Daily Traffic for Trucks |
| AADTYR | aadtyr | aadtyr | Text | The calendar year (YYYY) in which the annual average daily traffic count applies for the highway segment. |
| CALYR | calyr | calyr | Text | The last calendar year in which the data was updated. |
| COUNTYEAR | countyear | countyear | Text | The year the data was recorded |
| DD | dd | dd | Number | Directional Distribution -The percentage of the design hour value flowing in the peak direction. |
| DHV | dhv | dhv | Number | The 30th highest annual hourly traffic volume expressed as a percentage of AADT |
| EDLA | edla | edla | Number | Equivalent Daily Load Axle |
| OFFPKTRK | offpktrk | offpktrk | Number | The Peak percent of AADT that is composed of trucks of all types. Calculated by taking the number of trucks divided by the AADT |
| PCTOFFPKCO | pctoffpkco | pctoffpkco | Number | Percentage of AADT for Combination Trucks During Off-Peak Periods |
| PCTOFFPKSU | pctoffpksu | pctoffpksu | Number | Percentage of AADT for Single Unit Trucks During Off-Peak Periods |
| PCTPKSU | pctpksu | pctpksu | Number | Percentage of AADT for single unit trucks during the Peak Hour. |
| PCTPKCOMB | pctpkcomb | pctpkcomb | Number | Percentage of AADT for Combination Trucks During the Peak Hour. |
| PKTRK | pktrk | pktrk | Number | The Peak percent of AADT that is composed of trucks of all types. Calculated by taking the number of trucks divided by the AADT |
| ROUTECAPAC | routecapac | routecapac | Number | The maximum number of vehicles which has a reasonable expectation of passing over a given section of lane or roadway during a given time period under prevailing roadway and traffic conditions per the Highway Capacity Manual. |
| VCRATIO | vcratio | vcratio | Number | The hourly traffic volume divided by the capacity of the segment. Thus, the volume/capacity ratio measure can be assumed to measure capacity sufficiency and delay is a measure of the quality of service. |
| VCRATIO20 | vcratio20 | vcratio20 | Number | The 20 year projection for the VCRATIO value. |
| YR20FACTOR | yr20factor | yr20factor | Number | A traffic forecasting statistic that gives an estimate of AADT for 20 years in the future. |
| ROADTERRAI | roadterrai | roadterrai | Text | A Domained Value Element (terrain 0-3) used to identify the Predominant type of terrain through which the road segment passes as specified by AASHTO. |
| SEASONALGR | seasonalgr | seasonalgr | Text | A Domained Numeric Designation (seasonalGroupID, 1-7) indicating the Coded Value associated with a list of Seasonal Variations used for short term data calculations. |
