More than half of the world’s population lives in urban areas, and countries such as India and China are in need of hundreds of additional cities to accommodate growing populations. People in many cities suffer from inadequate transportation, sub-standard buildings, lack of sanitation, and poor public safety, highlighting the need for sustainable and livable urban planning. Information and communication technology (ICT) can be a useful tool in helping cities improve their safety, cleanliness, and sustainability.
ICT not only contributes to sustainable urban initiatives, but also encourages more environmentally conscious consumer choices. In Singapore, for example, commuters can use mobile phones to avoid hours in traffic by accessing data mapping tools that display traffic and provide alternate travel routes. Commuters can also plan trips on public transportation and be notified of delays or changes in service.
