Cities are growing vertically as well as horizontally, so infrastructure needs to ensure people can move up and down as well as across the city.
Cities are expanding upwards and downwards, as well as outwards. With urban density also increasing, moving people efficiently around the city, often using ageing infrastructure, is quite a challenge.
Smart bus use can transform public transport in cities, as EMBARQ is doing in Brazil.
Trains and trams get most attention, but 'tweaking' bus transit can transform cities. Buses can be more cost-effective and deliver better service, especially for small to mid-sized cities.

New York soon may charge a fee to drive into central Manhattan as a way of reducing traffic and raising funds for public transit. An urban scholar says this step is overdue in the United States.
The presence of sidewalks, green space, healthy food outlets, and trustworthy neighbours can all play a part in minimizing your risks of heart disease.
As 'Heart Month' kicks off across North America, a cardiovascular researcher explains how the neighbourhood you live in can affect your risks of heart disease.
