The study is aimed at estimating road lighting impact on traffic stream characteristics; flow, speed, density and headway for an uninterrupted traffic flow. 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 density and headways during daylight and road lighting periods did not differ significantly: the study concluded that road lighting does not affect traffic stream characteristics significantly.
