Percentage of people with access to reliable transport solutions all year-round

The percentage of the population that has safe and dependable transportation options throughout the year. In urban areas this measures the estimated share of urban population who can access a public transport stop within a walking distance of 500 meters (for low-capacity public transport systems) and/or 1,000 meters (for high-capacity public transport systems) along the street network.[1] In rural areas this measures the proportion of the rural population who lives within 2 km of an all-season road.[2] A country-level indicator is a weighted average of the rural and urban dimensions, weighted by the rural-urban population split in a given country.
___
[1] Low-capacity public transport systems include buses and trams, while high-capacity public transport systems include trains, ferries, and subways.
[2] An all-season road is a function of passability; paved roads are more likely than unpaved roads to be all-season passable, but not always. It depends on surface conditions as well as the roads’ exposure to rainfall and the specific topography.
