<p>This study assesses the performance of sidewalk pavement materials by evaluating five parameters that influence pedestrian safety and comfort: surface roughness, friction, texture, heat retention, and solar reflectance. Conducted along a pedestrian route in Braga, Portugal, this research adapts methods commonly used in road pavement analysis at seven testing points paved with different materials. In addition, a novel stroller-mounted sensor system was employed to continuously assess surface conditions, enabling high-resolution data collection and real-time evaluation of sidewalk conditions. The results revealed significant disparities in material performance across the five parameters. Granite blocks exhibited high roughness values (with deformations up to 12&#xa0;mm), increasing the risk of tripping. Sidewalks paved with stone slabs and Portuguese pavement registered Pendulum Test Values below 35, indicating a moderate slipping risk. Thermal differences of up to 11.5&#xa0;°C were observed between materials, with temperature fluctuations exceeding 30&#xa0;°C between sun-exposed and shaded areas. The findings underscore the importance of material selection and maintenance strategies to enhance pedestrian infrastructure safety and comfort. By integrating pavement engineering methodologies into sidewalk evaluation, this study provides valuable and replicable insights for urban planners and researchers to create more walkable and pedestrian-friendly cities.</p>

摘要

This study assesses the performance of sidewalk pavement materials by evaluating five parameters that influence pedestrian safety and comfort: surface roughness, friction, texture, heat retention, and solar reflectance. Conducted along a pedestrian route in Braga, Portugal, this research adapts methods commonly used in road pavement analysis at seven testing points paved with different materials. In addition, a novel stroller-mounted sensor system was employed to continuously assess surface conditions, enabling high-resolution data collection and real-time evaluation of sidewalk conditions. The results revealed significant disparities in material performance across the five parameters. Granite blocks exhibited high roughness values (with deformations up to 12 mm), increasing the risk of tripping. Sidewalks paved with stone slabs and Portuguese pavement registered Pendulum Test Values below 35, indicating a moderate slipping risk. Thermal differences of up to 11.5 °C were observed between materials, with temperature fluctuations exceeding 30 °C between sun-exposed and shaded areas. The findings underscore the importance of material selection and maintenance strategies to enhance pedestrian infrastructure safety and comfort. By integrating pavement engineering methodologies into sidewalk evaluation, this study provides valuable and replicable insights for urban planners and researchers to create more walkable and pedestrian-friendly cities.
