Accessible Routing

The calculation of travel routes that account for accessibility barriers and the specific mobility needs of disabled pedestrians. Unlike standard navigation that optimises solely for distance or time, accessible routing considers factors such as kerb heights, stairs, surface conditions, slope gradients, crossing safety, and the presence of tactile paving or other orientation features. Accessible routing may be personalised to individual capabilities — for example, a wheelchair user needs step-free routes while a blind pedestrian may prioritise routes with audible crossing signals and tactile ground indicators. Crowdsourced accessibility data from disabled users themselves is increasingly used to supplement standard map data for accessible route calculation.
