According to experts at the World Bank and the World Resources Institute (WRI), many people are moving to cities. In fact, half of the world’s population now lives in urban areas, which means that these regions are expanding rapidly with new buildings and roads. It also means more traffic congestion, with cities creating 1.2 million traffic accident fatalities annually.
Many safety experts say that it does not have to be this way and that cities can become safe places with good, sustainable designs. The problem, some critics feel, is that current cities are not always designed for future population growth or even to handle the current population numbers, creating congestion and other problems.
