Pedestrian Navigation System

A navigation system designed specifically for people travelling on foot, as opposed to systems designed for car drivers. Pedestrian navigation systems must account for footpaths, crosswalks, stairs, pedestrian bridges, and indoor routes that vehicle-focused systems typically ignore. For disabled pedestrians, these systems may need to incorporate accessibility data such as kerb cuts, ramp locations, surface conditions, and crossing signal types. Challenges include lower GPS accuracy in urban canyons and indoors, the need for finer-grained map data than car navigation requires, and the diverse mobility needs of different user groups.
