Abstract

Walking to and from school has significant implications for children's physical and mental well-being. This study aims to investigate the accuracy of routing engines (Google Maps, Mapbox, and OSRM) in replicating GPS trajectories and explore potential associations with gender and socioeconomic status. The study analysed GPS data from 227 children aged 10-11 years old in Scotland. The results indicated that OSRM exhibited the highest accuracy with a mean GPS track overlap of 56%. However, no substantial differences were found between the routing engines. Additionally, the accuracy of the engines did not vary based on gender or socioeconomic status. These findings provide reassurance that potential biases do not arise when using these navigation tools, as their accuracy remains consistent across different demographic groups.
