Content

Sequence [1..1]
1. st:RoadwayStructureIdentification [0..*]A unique federal inspection/inventory identification assigned to a bridge, underpass, overpass, or tunnel bridge/structure that is also linkable to the national bridge inventory.
2. st:RoadwayInclinationValue [0..*]An inclination of the roadway, expressed in the rate of rise or fall in feet (meters) per 100 feet (meters) of horizontal distance.
3. st:AADTRampNumeric [0..*]An AADT on ramp
4. st:ThroughLanesNumeric [0..*]A total number of through lanes on the segment. This excludes auxiliary lanes, such as collector-distributor lanes, weaving lanes, frontage road lanes, parking and turning lanes, acceleration/deceleration lanes, toll collection lanes, shoulders, and truck
5. st:BridgeStructure [0..*]A bridge, underpass, overpass, or tunnel bridge/structure that is also linkable to the national bridge inventory.
6. st:RoadwayCurveApplicableIndicator [0..*]True if road curvature measurement parameters are applicable to this particular road part; false otherwise.
7. st:RoadwayCurveRadiusLengthMeasure [0..*]A measurement of the curvature in the roadway expressed in terms of its radius (use feet or meters).
8. st:RoadwayCurveLengthMeasure [0..*]A measurement of the curvature in the roadway expressed in terms of its length (use feet or meters).
9. st:RoadwayCurveSuperelevationMeasure [0..*]A measurement of the curvature in the roadway expressed in terms of its superelevation (use feet or meters).
10. st:RoadwayGradeSlopePercent [0..*]An inclination of the roadway, expressed in the rate of rise or fall in feet (meters) per 100 feet (meters) of horizontal distance.
11. st:AverageAnnualDailyTrafficNumeric [0..*]An AADT value to represent the current data year. For two-way facilities, provide the AADT for both directions; provide the directional AADT if part of a one-way couplet or for one-way streets
12. st:RoadwayLaneWidthMeasure [0..*]A width of the lane(s) where crash occurred (use feet or meters).
13. st:RoadwayShoulderWidthMeasure [0..*]A widths of the shoulder(s) where crash occurred (use feet or meters).
14. st:RoadwayMedianWidthMeasure [0..*]A width of portion of divided highway separating the road for traffic in opposing directions where the crash occurred. If a crash occurs at a mid-block section, the median width is based on the mid-block section. If the crash occurs at an intersection, the
15. st:RoadwayRailwayCrossingIdentification [0..*]A unique US DOT/AAR number assigned for identification purposes to a railroad crossing by a state highway agency in cooperation with the Federal Railroad Administration.
16. st:RoadwayIntersectionAverageAnnualDailyEnteringTrafficQuantity [0..*]A total number of entering vehicles for all approaches of an intersection. Actual or estimated traffic volume expressed as an average annual daily count.
