Highway-Railroad Grade Crossing Program
Anytime a roadway crosses railroad tracks, there is a risk of a collision. And in a collision with a train, you are 20 times more likely to be killed than if you were in a collision with another car. The objective of TDOT’s Highway-Railroad Grade Crossing Program is to improve safety and reduce crash risk at Tennessee’s public highway-railroad grade crossings. “Grade” crossings refers to those crossings at which the highway and railroad are at the same level, as opposed to “grade separated” crossings in which there is a bridge to allow one to pass over the other.
Tennessee’s Highway-Railroad Grade Crossing Program, commonly referred to as the Section 130 Program, is a federal aid program authorized by United States Code Title 23, Section 130, and administered through the state by the Federal Highway Administration (FHWA). Typically, Section 130 funds are used to install warning devices, such as train-activated flashing lights, automatic gates, and warning bells. These funds may also be used to provide various other safety improvements at existing crossings and to assist in the closure of unneeded crossings.
Tennessee typically receives about $4,600,000 in Section 130 funds annually. The typical cost of a Section 130 Program safety improvement project is from $180,000 to $280,000. Priority for the available funds is given to crossings with the greatest likelihood of a collision occurring. This is determined using an FHWA accident prediction model, which takes into consideration many factors including:
- average daily traffic on the highway
- number of train movements per day
- maximum train speed
- crash history (if any)
The Highway-Railroad Grade Crossing Program maintains a crossing inventory database, including information about warning devices and signage, for each public crossing in Tennessee. The information is used to prioritize crossings for projects and to update the national crossing inventory database maintained by the Federal Railroad Administration (FRA). For more information, see the FRA National Grade Crossing Inventory.
