Thirty years ago, Curitiba’s forward-thinking and cost-conscious planners integrated public transportation into all the other elements of the urban planning system. They initiated a system that focused on meeting the transportation needs of all people. Consequently they claim to have a system that is both efficient and accessible.
While the tube shaped bus shelters seem a little cumbersome being raised up to be level with the bus entry, they shelter travellers from the weather and create a relatively level entry to and from the bus. They also claim that time spent at each stop is less than 30 seconds. Read more about the planning of this rapid transport system in southern Brazil. It should be noted that this is not common practice in other parts of Brazil. See this paper for the other side of the story and for a case study on the accessibility (or otherwise) of a local hospital.
