Part 8. TRAFFIC CONTROL FOR RAILROAD AND LIGHT RAIL TRANSIT GRADE CROSSINGS Chapter 8A. General 8A.1 Introduction Whenever the acronym "LRT" is used in Part 8, it refers to "light rail transit." Part 8 describes the traffic control devices that are used at highway-rail and highway-LRT grade crossings.

Raub, R.A. Examination of highway-rail grade crossing collisions nationally from to Indiana has more at grade public highway-rail crossings than all but four other states.
Indiana also has a large number of grade-separated crossings. More than half of the at grade public highway-rail crossings in Indiana have train-activated warning devices, which is better than the national average. TRB's National Cooperative Highway Research Program (NCHRP) Synthesis Traffic Signal Preemption at Intersections Near Highway–Rail Grade Crossings documents the current practices of traffic signal preemption deployed at intersections adjacent to railway grade crossing in both the United States and Canada.

A level crossing is an intersection where a railway line crosses a road or path, or in rare situations an airport runway, at the same level, as opposed to the railway line crossing over or under using an overpass or term also applies when a light rail line with separate right-of-way or reserved track crosses a road in the same fashion.

() survey of 1, drivers conducted to determine driver understanding of traffic control devices at highway-rail crossings, 82 percent of the respondents correctly identified the meaning of the "YIELD TO TRAINS" experimental sign (i.e., "Yield the right-of-way if a train is approaching a crossing").
In addition, the national Manual on Uniform Traffic Control Devices (MUTCD), Which has been adopted as a standard by the Division of Highways, permits the installation of STOP signs at selected railroad grade crossings after their need has been determined by a detailed traffic engineering study (MUTCD), Section 2B-5).

No national or state warrants have been developed for installation of traffic control devices at grade crossings. Furthermore, due to theFile Size: KB. Transportation (DOT) concluded that it was anomalous that railroad grade crossings were “the only place along the highway where the state authorities do not have total control over the installation of traffic control devices” (DOT, ).
The subsequent political debate led to the Federal-Aid Rail-Highway Crossing Program as. Highway-Rail Grade Crossings. A highway-rail grade crossing is an intersection where a roadway crosses railroad tracks at the same level or grade.
Such crossings may be encountered on both public and private roads. There are more thansuch crossings in the U.S. Although the highway safety picture has improved considerably over the last. Traffic control devices placed on or adjacent to a highway, or in advance of a crossing, including pavement markings and circuitry.
