Investigation of Factors Affecting the Duration of Full-Lane-Closure Accidents on the Freeway
A full-lane-closure accident refers to a traffic accident in which one or both directions of a freeway are completely obstructed, thus resulting in severe traffic congestion. Traffic operators must … [Read more...] about Investigation of Factors Affecting the Duration of Full-Lane-Closure Accidents on the Freeway
From Chaos to Order: Evaluating Behavior-Driven Road Sign Strategies in Work Zone Management
Road construction significantly impacts traffic dynamics, often causing severe congestion, reduced speeds, and elevated accident risks due to lane closures and merging bottlenecks. This study employs … [Read more...] about From Chaos to Order: Evaluating Behavior-Driven Road Sign Strategies in Work Zone Management
Evaluating the Intensity of Green Warning Light for Snowplow Trucks Using CIELAB Color Space
Snowplow Trucks (SPTs) work under extremely challenging conditions, typically traveling at lower speeds compared with other vehicles. Because of reduced speeds and poor visibility, a major safety … [Read more...] about Evaluating the Intensity of Green Warning Light for Snowplow Trucks Using CIELAB Color Space
