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:

Figure 2-84: Width and length measurement diagram

1. Highway System

Figure 2-89: U.S. DOT-FRA Crossing Inventory Form Part V, Item 1

Check the box for the correct highway system code. See Table 2-1 below for the correct code.

Table 2-1: Highway System Codes
Code Definition Included
01 Interstate Highway System Interstate, rural, and urban; (note
that the Interstate is part of the
National Highway System)
02 Other National Highway System (NHS) Other urban and rural principal arterial, Non-Interstate
03 Federal Aid Highway, Not NHS Rural major collector and higher category, or urban collector and higher category, not part of NHS
08 Non-Federal Aid Local rural roads, rural minor collectors, and local urban city streets or any other non-FederalAid roadway




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.

5. Linear Referencing System (LRS Route ID)

Figure 2-93: U.S. DOT-FRA Crossing Inventory Form Part V, Item 5
This is an optional field. Enter the “Linear Referencing System (LRS Route ID)” code. The LRS is a set of procedures for determining and retaining a record of specific points along a highway. Typical methods used are milepoint, milepost, reference point, and link-node.

It is recommended that this field use the Highway Performance Monitoring System (HPMS) data reported to FHWA. If a State uses more than one LRS for their own purposes, it is recommended that the information entered match the HPMS data. The details for the HPMS can be found on FHWA’s Web site at: http://www.fhwa.dot.gov under Highway Performance Monitoring System.

6. LRS Milepost

Figure 2-94: U.S. DOT-FRA Crossing Inventory Form Part V, Item 6

This is an optional item. Enter the LRS milepost designation. Most at-grade highwayrail grade crossings are on highways without posted mileposts. Leave blank if none are posted.

Figure 2-95: U.S. DOT-FRA Crossing Inventory Form Part V, Item 7

Enter the calendar year when the AADT was determined and the estimated AADT count through the crossing (total both directions) based on available traffic information. When a crossing runs diagonally through a highway-highway intersection, the total AADT should include both streets in both directions.

“Annual Average Daily Traffic (AADT)” – a figure that represents the amount of vehicles traveling past a known location on a roadway for a year, divided by 365 days. In the event that 365 consecutive days of traffic counts are not available, there are traffic engineering calculations that can be used to develop a representative figure for AADT based upon traffic counts of shorter duration.

8. Estimated Percent Trucks

Figure 2-96: U.S. DOT-FRA Crossing Inventory Form Part V, Item 8
Enter the estimated percentage (0–99%) of trucks in the traffic stream. For the purposes of this manual, trucks are considered as those vehicles having a manufacturer’s gross vehicle weight (GVW) rating of 9,000 lbs. or more and having dual tires on at least one rear axle. Also, buses, single-unit trucks, combination trucks, and campers/recreational vehicles are classified as trucks. Do not include school buses.
