This research investigates the impact of pedestrian crossings on the speed characteristics and capacity of roundabouts, with a primary focus on enhancing traffic flow. Unsignalized intersections and roundabouts conventionally grant pedestrians priority, which can substantially affect operational efficiency. The paper underscores the vital significance of strategically placing crosswalks to minimize disruptions to vehicular movement and prevent congestion.The study collected data from roundabouts located in Marrakech, Morocco, utilizing mobile devices to record vehicle and pedestrian counts, as well as their passage times. In addition to field data, Vissim simulations were employed to improve precision. Our research specifically delves into how pedestrians influence the capacity of exit lanes at roundabouts.The central objective is to ascertain the optimal spacing between roundabouts and crosswalks to maximize their capacity. The findings provide valuable insights for urban planning and traffic management, addressing the intricate relationship between pedestrian flow, crosswalk placement, and the overall efficiency of roundabouts.
