Read the following passage and answer the questions based on the passage:
Good public transport networks are the pillars of urban sustainability. Buses, trams, and metro lines can transport big groups of passengers without relying so much on private cars – and therefore eliminating traffic snarls and emissions. Integrated fares across modes of travel make it easy to move around: one ticket could pay for bus, train, and bike-share travel. Spending money on exclusive lanes and priority signaling also makes them faster and more dependable. Nonetheless, constructing and retaining such infrastructure requires capital and long-term vision. Equity issues are also important: lines need to serve low-income communities along with commercial hubs so that all citizens have a benefit. Finally, when properly planned, public transportation promotes economic efficiency, social mobility, and a cleaner city.
