Leading Pedestrian Intervals Impact on Pedestrian Injury: A Scoping Review Protocol
(2025-05-18) Denning, Michael; Kyajia Mourning; Pressley, Joyce
Pedestrian safety remains a critical public health concern, particularly in urban environments where conflicts between motor vehicles and pedestrians occur more frequently. In order to counteract this mechanism of injury at intersections, Leading Pedestrian Interval (LPIs) have been implemented in both urban and rural settings. LPIs are a traffic signal timing strategy that provides pedestrians with increased time to enter the crosswalk of intersections where they are more visible to a turning vehicle before the vehicle receives the green light to proceed through the intersection. Current reports vary in terms of the amount of lead time the pedestrian is given and the types of intersections in which they are effective. Despite being a low cost alternative that is highly effective under certain conditions, LPIs have failed to be scaled up particularly in some neighborhoods. As the evidence-base continues to evolve, this scoping review aims to examine the current evidence that continues to evolve and to identify gaps in that evidence that may be an impediment to using this strategy to impact pedestrian injury, injury severity, and mortality.
Traffic Calming Interventions Impact on Pedestrian Injury: A Scoping Review Protocol
(2025-05-19) Kyajia Mourning; Denning, Michael; Pressley, Joyce
Pedestrian injuries and fatalities remain a persistent global public health issue, particularly in urban areas where motor vehicle traffic and pedestrian activity intersect. Traffic-calming interventions, or physical or design-based strategies intended to reduce vehicle speeds, are implemented worldwide to reduce pedestrian injuries, injury severity, and mortality. At the same time, individual studies prompt encouraging outcomes and an overarching analysis of the effectiveness and contextual impact of the inventions. Given the diversity of traffic calming interventions and inconsistent reporting of their effects on pedestrian outcomes, a scoping review is warranted. This revenue will outline existing research on how traffic calming interventions influence pedestrian injury, severity, and mortality.
