Public transport

Public transport is the network of buses, trams, metros and trains that moves many people in little space: a bus lane carries five to ten times more people per hour than a car lane. Its quality —frequency, coverage, fares— decides job access for those who do not drive.

Curitiba invented high-capacity bus rapid transit in the 1970s and Bogotá scaled it with TransMilenio; Santiago learned with Transantiago that redesigning the whole network at once carries an enormous political cost. The recent debate is free fares: Tallinn, Luxembourg and Kansas City tried it with mixed results.
