Traffic control for highway-rail grade crossings includes all signs, signals, markings, other warning devices, and their supports along highways approaching and at highway-rail grade crossings. The function of this traffic control is to permit reasonably safe and efficient operation of both rail and highway traffic at highway-rail grade crossings.
This information has been compiled from leading experts in both the public and private sectors to provide a robust resource for anyone who deals with highway rail at-grade crossings.
Seven Points Every Traffic Engineer Should Know About Rail Preemption Installations. The presence of a nearby traffic signal has been identified in traffic safety studies as a leading indicator of grade crossing collisions. Preemption of Traffic Signals At or Near Railroad Grade Crossings with Active Warning Devices, was published (Institute of Transportation Engineers ), the proposed recommended practice Preemption of Traffic Signals Near Railroad Crossingswas electroni-cally published, and two new editions of the Manual on Uniform Traffic Control Devices.
Another aspect of grade crossing design is coordination of highway traffic signal operations with grade crossing active warning devices (“railroad preemption”) when signalized intersections are located near grade crossings. In such instances, railroad preemption is designed to clear the tracks of any vehicles that may be stopped as a.

Many roadway intersections throughout North America are located near highway–railroad grade crossings (IHRGCs). Numerous safety, operational, and legal challenges are associated with IHRGCs; and these become significantly more complex when traffic signals are present.
Because of the complexity of traffic operations at IHRGCs, existing macroscopic analysis Cited by: 1. RAIL GRADE CROSSINGS Traffic Engineering Manual Revised Janu Octo Part 8 – RAIL GRADE CROSSINGS GENERAL OMUTCD Part 8 addresses traffic controls at highway-rail grade crossings and highway-light rail grade crossings.
Very few, if any routes under ODOT’s jurisdiction involve traffic control at File Size: KB. A: Yes, but only at highway-LRT grade crossings where a Crossbuck sign is used. Paragraphs 3 and 4 of Section 8B in the MUTCD indicate that the use of a Crossbuck sign is required at all highway-rail grade crossings, but is optional at highway-LRT grade crossings.
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.
Unless otherwise provided in the text or on. A key component of the safe and efficient operation of traffic signals near highway–rail grade crossings (HRGCs) is an accurate estimate of a given train's arrival time at each by: 2.
Traffic control for grade crossings includes all signs, signals, markings, other warning devices, and their supports along highways approaching and at grade crossings.
The function of this traffic control is to promote safety and provide effective operation of rail and/or LRT and highway traffic at grade crossings. Traffic Signal Preemption at Intersections Near Highway–Rail Grade Crossings.
TRB's National Cooperative Highway Research Program (NCHRP) Synthesis Traffic signal operations near highway–rail grade crossings are important from both safety and mobility perspectives, but practice varies widely. All signs used in highway-rail grade crossing traffic control systems shall be retroreflectorized or illuminated as described in Section 2A to show the same shape and similar color to an approaching road user during both day and night.

Rilett Because the operational characteristics of signalized intersections near highway-railroad grade crossings (IHRGCs) are.
The risks of a rear-end crash are greater than a train-vehicle crash, such as at crossings with low train volumes and speeds, but high vehicle volumes and speeds. Traffic at the crossing is controlled by a traffic signal that is interconnected to the crossing signals and train detection.
Related information. Rail Safety Week video. Highway-rail grade crossings (HRGCs) and the intersections in their proximity are areas where potential problems in terms of safety and efficiency often arise if only simple or outdated treatments, such as normal signal timing or passive railroad warning signs, are utilized.
Preemption of a traffic signal at or near a highway -rail at-grade crossing (Crossing) occurs when traffic signal operations are modified 1) to clear roadway users from a railroad track before a train arrives at a Crossing, 2) to prevent roadway users.
