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 …

Quantitative analyses of train derailment probability at highway-rail grade crossings
The current 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 …

Car Following and Dynamic Dilemma Zone Model for Determining Gate Operation Times Based on Driver Behavior at Highway-Rail Intersections
Field data is collected and analyzed from two highway-rail intersections. Vehicular speed profiles are examined in the approach zone, stopping distance zone, and the track zone for single vehicles as well as platoons of vehicles. A simulation model incorporating the field data, determination of a …

Optimizing Traffic Network Signals Around Railroad Crossings
… an approach, named "Signal Optimization Under Rail Crossing sAfety cOnstraints"(SOURCAO), to the traffic signal control near a highway rail grade crossing (HRGC). SOURCAO targets two objectives: HRGC safety improvement (a high priority national transportation goal) and highway traffic delay …

Analysis Of Queue Characteristics At Signalized Intersections Near Highway-Railroad Grade Crossing
… intersections which 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 …

Quantitative analyses of freight train derailments
Railroad safety analysis encompasses several areas, one of which is freight train risk analysis. There are various types of freight train accidents including derailments, collisions, highway-rail grade crossing incidents, and others. The mainline freight train derailment rate of the major U.S. …
