The roles of garment design and scene complexity in the daytime conspicuity of high-visibility safety apparel.
INTRODUCTION This study examines the effects of high-visibility garment design on daytime pedestrian conspicuity in work zones. Factors assessed were garment color, amount of background material, pedestrian arm motion, scene complexity, and driver age. METHOD The study was conducted in naturalistic conditions on public roads in real traffic. Drivers drove two passes on a 31-km route and indic...
متن کاملMotorcycle Conspicuity: Effects of Age and Daytime Running Lights
OBJECTIVE This study investigated variables that may contribute to motorcycle conspicuity within a high-fidelity simulated environment. The variables included motorcycle lighting, vehicular daytime running lights (DRLs), and age of the driver of the other vehicle. BACKGROUND Research suggests that decreased levels of conspicuity associated with riding a small two-wheeled vehicle reduce the ab...
متن کاملHigh visibility safety apparel and nighttime conspicuity of pedestrians in work zones.
PROBLEM Every year numerous occupational fatalities result from pedestrians being struck by motor vehicles intruding into work zones. METHOD Attributes of retroreflective personal safety garments on pedestrian conspicuity at night were assessed in a field study. Using instrumented vehicles on a closed track, participants drove through simulated work zones attempting to detect pedestrians loca...
متن کاملThe firefighter problem with more than one firefighter on trees
In this paper we study the complexity of the firefighter problem and related problems on trees when more than one firefighter is available at each time step, and answer several open questions of [8]. More precisely, when b ≥ 2 firefighters are allowed at each time step, the problem is NP-complete for trees of maximum degree b+2 and polynomial-time solvable for trees of maximum degree b + 2 when...
متن کاملEpileptic seizure detection based on The Limited Penetrable visibility graph algorithm and graph properties
Introduction: Epileptic seizure detection is a key step for both researchers and epilepsy specialists for epilepsy assessment due to the non-stationariness and chaos in the electroencephalogram (EEG) signals. Current research is directed toward the development of an efficient method for epilepsy or seizure detection based the limited penetrable visibility graph (LPVG) algorith...
