Abstract
Nighttime traffic accidents post a more serious problem than daytime accidents, especially when fatal and injurious road accidents and traffic volumes during the two periods are compared. This research paper represents the first attempt to identify the characteristics of nighttime road accidents in Riyadh, the capital city of Saudi Arabia. Records of every road traffic accident (7721) occurring during the year 1984 are analyzed and nighttime and daytime trends are compared. The roles of human factors, the road network, and vehicle components are incorporated in these comparisons. A x2 test of significance was also performed to verify the existence of a significant proportional difference between daytime and nighttime accidents. Finally, conclusions and recommendations for the improvement of road safety after dark in the Kingdom are made.
