Analysis of Responder-Involved Struck-by Crashes
… However, certain activities – such as setting up traffic incident management areas (TIMAs) and assisting disabled vehicles – significantly increase risks, particularly for fire department personnel and tow truck operators. Temporary traffic control devices show potential in reducing fatalities, …

Analysis Of Queue Characteristics At Signalized Intersections Near Highway-Railroad Grade Crossing
<p>Analysis of traffic queues at signalized 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 …

Evaluating the use of steady burn warning lights on drums for workzone safety
… often presents the challenge of maintaining traffic on the existing roadway while work is being performed, thereby necessitating the use of what is commonly referred to as a roadway "work zone". One of the most important components of traffic control in a work zone is delineation of the edge …
