Abstract

Due to the impact of geometric design on traffic safety, this research aims to compare the geometric design standards included in the Palestinian guidelines (the Road and Transportation Planning Guide in Urban Areas and the Road Traffic Safety Guide) with AASHTO standards. The comparison focused on key design elements; cross sections (lanes, shoulders, and medians), alignment (horizontal and vertical), sight distances, intersections, roundabouts, and access points. The research results showed a Palestinian interest in design quality and enhancing safety. However, there were still aspects that required further development, such as providing design details and proper coverage for rural roads. Based on this comparison, the study proposed recommendations to develop a comprehensive and unified national guideline consistent with international standards and safety requirements, and conduct analytical studies to link geometric design with traffic safety accidents in Palestine.
