Evaluating Roundabouts and Parking Reforms in Urban Traffic Management: Insights from Case Studies in the USA, Japan, and India

Abstract

Urban traffic congestion and road safety are critical challenges in the 21st century, exacerbated by rapid urbanization and increasing reliance on motor vehicles. This study evaluates the effectiveness of roundabouts, parking reforms, and pedestrian-friendly designs in improving road safety and urban livability. Through a systematic review of literature and case studies from Bristol, VA (USA), Japan, and India, the paper highlights the benefits of these interventions, including crash reduction, smoother traffic flow, and enhanced pedestrian safety. The findings underscore the importance of human-centered design, data-driven policies, and sustainable urban planning. Key recommendations include the adoption of roundabouts in high-traffic areas, district-based parking models, and integrated urban planning strategies. This study contributes to the growing body of knowledge on traffic management by providing actionable insights for policymakers and urban planners.
