Abstract:Pavement markings are crucial for ensuring the safe and efficient movement of vehicles, cyclists and pedestrians at crosswalks. They provide essential guidance in lane navigation, road sharing, and safety compliance. With growing emphasis on safety in urban areas, crosswalk markings are becoming more prevalent. The primary objectives of this project were to (i) assess slip resistance for pedestrians, PSR, and skid friction for vehicles, TSR, on crosswalk areas where pavement markings are used, and, (ii) relate vehicle pavement skid resistance to pedestrian slip resistance for a variety of conditions (i.e., wet versus dry, and/or icy conditions). The key findings of the study provided a consistent performance across both PSR and TSR measurements in dry, wet, and icy conditions. While the analysis confirmed the high repeatability of the BPT measurements, meaningful differences were observed between surface conditions (i.e., dry versus wet). All materials experienced reduced friction in wet and icy environments. Good relationships between lab and field data were established and relating the various surface conditions. Overall, this investigation provided critical insights into the relationship between pedestrian slip resistance and vehicular skid resistance. The findings suggest that Maryland’s current specifications, which focus on vehicle skid resistance, could be expanded to incorporate pedestrian slip resistance requirements for improved safety at crosswalks.
