Effect of Road Lighting on the Quality of Dual Carriageway Road Service

摘要

The study is exciting because it introduced a new quality of road service assessment approach. The study explored the effect of road lighting on the quality of dual carriageway road service. Based on the hypothesis that road lighting has no significant effect on the level of road service, an impact study was carried out in Skudai town, Malaysia. Twenty four hours continuous traffic volume, vehicle types and speeds data were collected during daylight, road lighting and dry weather conditions for two directional flows. Results show that travel speeds speed during daylight and road lighting periods did not differ significantly. The study concluded road lighting does not affect the quality of road service significantly.
