4.A. Does nearby Hwy Intersection have Traffic Signals?
Check either the “Yes” or “No” box to indicate whether or not a highway-highway
intersection within 500 feet has highway traffic signals.
Note: The distance (500 feet or less) is measured from the nearest rail, not from the
centerline of track.
4.B. Hwy Traffic Signal Interconnection
Check all that apply. If “Not Interconnected” is checked, do not check the other two
choices.
 “Not Interconnected” – crossings equipped with active warning systems that do
not have an electrical connection between the railroad active warning system and
the traffic signal controller assembly for the purpose of preemption.
 “For Traffic Signals” – crossings having an electrical connection between the
railroad active warning system and the traffic signal controller assembly for the
purpose of preemption.
 “For Warning Signs” – signs that are electrically connected to a railroad crossing
control circuit that is designed to illuminate the signs upon the approach or
presence of a train.

4.C. Hwy Traffic Signal Preemption
Check the appropriate box for the type of preemption. This field is not applicable if “Not
Interconnected” is chosen in field 4.B. and should be left blank.
Preemption is defined in the MUTCD as the transfer of the normal operation of highway
traffic signals to a special control mode.
In this instance preemption occurs as a result of a signal received from the railroad
active warning device system
Simultaneous preemption is defined in the MUTCD as notification of approaching rail
traffic that is forwarded to the highway traffic signal controller unit or assembly and
railroad active warning devices at the same time.
Simultaneous preemption results in the initiation of the highway traffic signal cycle at the
same time the highway-rail grade crossing warning system is activated.
Advance preemption is defined in the MUTCD as notification of approaching rail traffic
that is forwarded to the highway traffic signal controller unit or assembly by the railroad
equipment in advance of the activation of the railroad warning devices.
Advance preemption results in the initiation of the highway traffic signal cycle before the
highway-rail grade crossing active warning system is activated.
5. Highway Traffic Pre-Signals
Figure 2-75: U.S. DOT-FRA Crossing Inventory Form Part III, Item 5
Check the “Yes” box to indicate if highway traffic pre-signals are installed. Check the
“No” box if there are none. The “Storage Distance” and “Stop Line Distance” fields are
optional. Use feet as the measuring unit.
Pre-signals are used to control traffic approaching a grade crossing in conjunction with
the highway traffic control signal faces that control traffic approaching a highwayhighway intersection beyond the tracks. Pre-signals may be located on either the near
or far side of the railroad tracks, and may be mounted on the same cantilever structures
as the railroad’s flashing light warning devices.
 “Storage Distance” (for pre-signals only) is the distance available for vehicle
storage as measured 6 feet from the rail nearest the intersection to the
intersection stop line or the normal stopping point on the roadway.

 “Stop Line Distance” (for pre-signals only) is the distance between the stop line
and the crossing gates. This field should be left blank if the crossing is not
equipped with gates.
6. Highway Monitoring Devices
Figure 2-76: U.S. DOT-FRA Crossing Inventory Form Part III, Item 6
Check all boxes that apply. Note: The temporary installation of highway
monitoring devices (e.g., for research purposes) should not be reported to the
Crossing Inventory.
 “Check the “Yes” box if “Photo/Video Recording” is present at the crossing.
Photo/Video Recording is the use of high-resolution cameras to photograph or
record motorists driving under or around railroad crossing gates. The camera
equipment is typically mounted in a 12-foot-high bullet-resistant cabinet. There
may be signs, installed on all street approaches to the crossing, that inform
motorists that photo citations are being issued to violators at the crossing. Note
– The temporary installation of photo/video recording devices (e.g., for research
purposes) are not to be reported.
 Check the “Yes” box if “Vehicle Presence Detection” is present at the crossing.
Vehicle Presence Detection is system capable of detecting and reporting in real
time the presence of a vehicle on the crossing. An example includes a series of
looped wire, coils, or magnetometers that are placed below ground level within
the field side and gauge side of the railroad tracks, at a distance between the
approach gate and the exit gate. The loop detectors or magnetometers use a
magnetic effect caused by the presence of a roadway vehicle, which then sends
a signal to the exit gate to remain in the up position, or can send a signal to the

Enter the count of bells (either mechanical or electrical) present at the crossing as part

of the warning system. If there are none, enter “0.”

3.J. Non-Train Active Warning

Figure 2-72: U.S. DOT-FRA Crossing Inventory Form Part III, Items 3.J – 3.K

Check the appropriate box if there is “Flagging” or a “Flagman” (a member of the train

crew or other person who actively controls the flow of vehicular traffic using handsignaling devices or an Automated Flagger Assistance Device); “Manually Operated

Signals” (e.g., dual toned multi-frequency (DTMF)-controlled, push-button activated);

“Watchman” (a person assigned to provide warning that is not a member of the train

crew); or “Floodlighting” at the crossing. Only floodlighting—which is distinctive from

ordinary street lighting in intensity, light distribution, focus, or color—is to be reported.

Check “None” if applicable.

4.A. Does nearby Hwy Intersection have Traffic Signals?

Check either the “Yes” or “No” box to indicate whether or not a highway-highway

intersection within 500 feet has highway traffic signals.

Note: The distance (500 feet or less) is measured from the nearest rail, not from the

centerline of track.

4.B. Hwy Traffic Signal Interconnection

Check all that apply. If “Not Interconnected” is checked, do not check the other two

choices.

 “Not Interconnected” – crossings equipped with active warning systems that do

not have an electrical connection between the railroad active warning system and

the traffic signal controller assembly for the purpose of preemption.

 “For Traffic Signals” – crossings having an electrical connection between the

railroad active warning system and the traffic signal controller assembly for the

purpose of preemption.

 “For Warning Signs” – signs that are electrically connected to a railroad crossing

control circuit that is designed to illuminate the signs upon the approach or

presence of a train.

4.C. Hwy Traffic Signal Preemption

Check the appropriate box for the type of preemption. This field is not applicable if “Not

Interconnected” is chosen in field 4.B. and should be left blank.

Preemption is defined in the MUTCD as the transfer of the normal operation of highway

traffic signals to a special control mode.

In this instance preemption occurs as a result of a signal received from the railroad

active warning device system

Simultaneous preemption is defined in the MUTCD as notification of approaching rail

traffic that is forwarded to the highway traffic signal controller unit or assembly and

railroad active warning devices at the same time.

Simultaneous preemption results in the initiation of the highway traffic signal cycle at the

same time the highway-rail grade crossing warning system is activated.

Advance preemption is defined in the MUTCD as notification of approaching rail traffic

that is forwarded to the highway traffic signal controller unit or assembly by the railroad

equipment in advance of the activation of the railroad warning devices.

Advance preemption results in the initiation of the highway traffic signal cycle before the

highway-rail grade crossing active warning system is activated.
