Abstract

This study evaluated 10,668 Traffic Calming Measures in Riyadh, Saudi Arabia, against current international and national standards. Data collection included the types of measures, construction materials, intended purposes, the presence of traffic safety features, and compliance with applicable standards. Vehicle speeds were analyzed before, at, and after encountering these measures, focusing on their types and heights. An assessment of existing construction procedures identified several shortcomings, prompting the development of a new approval process based on a point-scoring system informed by previous studies, local experiences, and international standards. The analysis demonstrated that traffic calming measures constructed according to standards improved driver and vehicle comfort while consistently reducing speeds to the target range. The study recommends implementing traffic calming measures through a systematic point-scoring method rather than citizen requests. This approach prioritizes locations with greater safety concerns and provides justification for the selection process to the public.
