Review of infrastructure measures for pedestrian safety at unsignalized crossings

Pedestrian safety at unsignalized crossings remains a critical challenge, as the absence of traffic signals increases the risk of accidents, particularly among vulnerable groups such as children and young adults. The aim of this systematic review is to identify and evaluate effective infrastructure measures to improve pedestrian safety at unsignalized intersections. A structured search was conducted across major engineering databases, and eligible studies were assessed using a standardized weight of evidence framework. The identified infrastructure measures were categorized into four key groups: engineering modifications, additional lighting, signage enhancements and smart technologies. This review provides a comprehensive synthesis of current best practices and highlights the importance of integrating quantitative assessment frameworks, such as the iRAP star rating system, to guide future infrastructure planning and policy decisions aimed at enhancing pedestrian safety at unsignalized crossings.
