Experimental evaluation of retroreflective markings on trains and grade crossings
… United States, hundreds of accidents occur at grade crossings due to motor vehicles colliding with trains. Furthermore, a large majority of these accidents take place at night in rural areas. One proposed solution to prevent such accidents involves mounting retroreflective material on the sides …

A microsimulation analysis of highway intersections near highway-railroad grade crossings
… analyses on intersections near Highway-Railroad Grade Crossings (HRGCs) to determine if controlling mean train speed and train speed variability would improve safety and reduce delays. This research focused on three specific areas. First, average vehicle delay was examined, and this delay was …

Quantitative analyses of train derailment probability at highway-rail grade crossings
… methodology for prioritizing highway-rail grade crossing (HRGC) warning system upgrades focuses on the likelihood of collisions and highway user casualties at crossings. However, these two metrics do not encompass all crossing risks. Specifically, they do not consider the potential for …

Dynamic method to identify and visualize accident contributing factors at highway-rail grade crossings
Highway-Rail grade crossings are important locations on a highway network and safety at these locations is a critical issue for both highway and railroad network. Even though safety at grade crossings have improved over the years, over 200 people still lose their lives every year at grade crossings …

Driver injury severity at u.s. highway-rail crossings
There are approximately 240,000 highway-rail grade crossings in the United States and highway-rail grade crossing areas have been considered in this study as these are locations where crashes frequently occur. Existing studies on crash models at highway- rail grade crossings can be classified into …

Channel Propagation Model for Train to Vehicle Alert System at 5.9 GHz using Dedicated Short Range Communication
… trains and passenger vehicles at railroad grade crossings [1][2]. Due to the size and speed of a train, these collisions generally result in significant damage and serious injury. Despite recent efforts by projects such as Operation Lifesaver to install safety features at grade crossings, …

Analysis Of Queue Characteristics At Signalized Intersections Near Highway-Railroad Grade Crossing
… are in close proximity to highway- railroad grade crossings is of primary importance for determining if the normal signal operation needs to be preempted for railroad operations by providing a special signal mode for safe clearance of the queued vehicles from the tracks before the train …

Model investigation of stress distribution in the knee of a skewed rigid-frame bridge
… of the most important being the elimination of grade crossings. The rigid frame bridge, introduced in this country in the early 1920's, offered a very satisfactory solution to the problem of grade separation. This type of structure was used quite extensively by the Westchester County Park …
