Public transport plays a key role in expanding the distances that people can travel using active modes of transport. Studying walking accessibility to public transportation systems is highly relevant, since the walk to stops/stations can be particularly challenging for children, the elderly, citizens with disabilities, and for the general population during bad weather conditions or in pedestrian-unfriendly cities. This work presents a study on walking accessibility for the public transport system in Montevideo, Uruguay. The proposed methodology combines information of the bus stops and lines that operate in the city, the road infrastructure, and demographic information of the city to compute walking accessibility indicators to the public transport system. The results of the analysis suggest that over 95.5% of the population can access at least one stop when walking up to 400 m. However, these values are not evenly distributed among the population, with young citizens and men showing lower levels of coverage compared to their counterparts.@en
