matrix, typically post-consumer recycled high-density polyethylene, or HDPE,
that are usually individually installed and removable for maintenance and
replacement purposes .
10. “Other (Specify)” – Surfaces other than the previously described surfaces,
including structural foam, plastic, “high-tech,” etc.
Note: This data field has been assigned to the State for updating. However, if
the railroad installs a new crossing surface, the railroad must report that change.
Enter the month and year that the crossing surface was originally installed and opened
to vehicular traffic in “MM/YYYY” format. Also, enter the width of the crossing, and the
length of the crossing. For new and updated crossing surfaces, the date and
measurements are required. These are optional fields for existing crossings that are
already reported, but encouraged to be submitted by State entities.
 “Width” – The width of the crossing surface is measured in feet perpendicular to
the railroad tracks and is the distance between the outermost edges of the
crossing surface (including multiple tracks if present). In the event that the
crossing surface is indistinguishable from the roadway approach, the width is the
distance between the outermost rails of the crossing plus 4 feet.
 “Length” – The length of the crossing surface is measured in feet parallel to the
tracks, along the improved surface of the crossing, which may extend beyond the
edges of highway pavement and any sidewalks that may be present. In general,
the crossing surface material will extend approximately 3 feet on each side
beyond the roadway/pathway.
Refer to the width and length diagram below:

6. Intersecting Roadway Within 500 Feet?
Figure 2-85: U.S. DOT-FRA Crossing Inventory Form Part IV, Item 6
Enter a check in the “Yes” box if the street or highway for this crossing is intersected by
another street or highway within 500 feet, and indicate the estimated distance from the
crossing. Check “No” when no intersection exists within 500 feet. If the street or
highway is intersected by another street or highway on both sides of the crossing,
indicated the estimated distance from the closest intersection.
7. Smallest Crossing Angle
Figure 2-86: U.S. DOT-FRA Crossing Inventory Form Part IV, Item 7
Enter a check in the box that most closely describes the smallest angle between the
roadway and the track.
8. Is Commercial Power Available?

Enter a check to indicate whether there is commercial electric power available within
500 feet of the crossing. This field is optional.

2. Functional Classification of Road at Crossing
Figure 2-90: U.S. DOT-FRA Crossing Inventory Form Part V, Item 2
Check the box for the appropriate highway functional classification code for “Rural” or
“Urban” and then check the box for the roadway type in accordance with Federal-aid
highway program definitions. The “Urban” designation is based on the U.S. Census
Bureau urban boundaries and a population of more than or equal to 5,000 people.
Functional classification is the grouping of highways, roads, and streets by the character
of service they provide and can be applied in planning highway system development. It
defines the part that any particular route should play in serving the flow of traffic through
a highway network. The details and definitions for classifying systems can be found on
FHWA's Web site at www.fhwa.dot.gov under “Guidelines for Functional Highway
Classification System.”
3. Is Crossing on State Highway System?
Figure 2-91: U.S. DOT-FRA Crossing Inventory Form Part V, Item 3
Check the appropriate box.
4. Highway Speed Limit
Figure 2-92: U.S. DOT-FRA Crossing Inventory Form Part V, Item 4
Enter the highway speed limit at the crossing in miles per hour (the speed limit value
must be greater than zero). Check the appropriate box to indicate whether the speed
limit is posted or statutory.
