Volume, speed and headway data were collected during daylight, road lighting and dry weather conditions. Flowrate, speed, density and headways were estimated for daylight and road lighting periods; then compared. Since flowrate, free-flow speed, optimum speed critical … …American Journal of Applied Sciences, Vol. 10, Issue 7 · 2 Jul 2013 · 7,020 accessesView PDFCite
