Research ArticleOpen accessIn the keywordsDetermining Road Lighting Impact on Traffic Stream CharacteristicsBen-Edigbe Johnnie, Kurnia Yuli AstridThe 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 … …American Journal of Applied Sciences, Vol. 10, Issue 7 · 2 Jul 2013 · 7,020 accessesView PDF Cite

Research ArticleOpen accessIn the abstractDetermining the Impact of Darkness on Highway Traffic Shockwave PropagationParameswary Sundara, Othman Che Puan, Mohammad Rosli HaininDuring darkness visibility diminishes resulting in reduced sight distances and drivers are subjected to anxiety that may give way to anger and frustration. However, the study is concerned with traffic shockwave propagation that could be associated with darkness on highways. Based on the hypothesis that darkness may induce temporary traffic shockwave propagation in the presence of substantial traffic volume, darkness … …American Journal of Applied Sciences, Vol. 10, Issue 9 · 24 Aug 2013 · 7,071 accessesView PDF Cite

Research ArticleOpen accessIn the abstractThe Effect of Digital Count-Down Display on Signalized Junction PerformanceM. R. Ibrahim, M. R. Karim, F. A. KidwaiIntersections are bottleneck in the highway networks and critical determinant of system’s capacity and safety. Recently, several countdown timers had been installed at intersections in Kuala Lumpur and some other cities in Malaysia. The function of these timers is to aid drivers to judge the amount of time left for them to get the green signal for moving (starting) their … …American Journal of Applied Sciences, Vol. 5, Issue 5 · 31 May 2008 · 7,761 accessesView PDF Cite
