This legislation mandates the Secretary of Transportation, acting through the Federal Highway Administration, to issue guidance within one year of its enactment. This guidance will clarify the types of state projects eligible for federal funding under existing programs. Specifically, it will describe projects under section 130(e)(1)(B) of title 23, United States Code, for which states may use funds set aside under section 130(e)(1)(A) of the same title. The primary objective of these projects is to reduce trespassing fatalities at railway-highway crossings. By providing clear direction, the bill aims to facilitate the effective use of existing funds for critical safety improvements.
