The area was modelled in 3D before any construction was put in place. The Housing & Development Board (HDB) from Singapore is creating the Punggol Eco-Town in the northeast part of the Singapore island. A smart city starts at the planning stage. However, smart cities are not simply urban areas dotted with sensors and other high-tech gadgets. A range of sensors can also provide information on air pollution, noise and river levels that could be used to prevent floods. Weather sensors can manage automatic watering systems for green areas and detect leaks. Waste containers can inform the waste collection company when they are full. Smart roads can send information on traffic and road accidents to drivers and suggest a better route and traffic lights can adjust to regulate traffic flows and prevent traffic jams (see Figure 1).Īnother example is on waste collection. It can also promptly send information to hospitals and to the police about car accidents and robberies. Sensors installed in the light posts can turn lights on and off, depending on whether there is movement in the surrounding areas. Street lights can gather and send information on the traffic in real time and send information on whether there is an empty parking spot to drivers looking to park in the area. What makes a city smart? An example in Singapore Both Nairobi and Cape Town look at Singapore as a role model for the city of the future. Going south, Cape Town blossoms as one of the best places to do business in the continent as the South African government continuously implements thoughtful planning and cutting edge technology to attract businesses and improve the lives of its citizens. Nairobi, capital of Kenya and home to over three million people, won the title of Most Intelligent City in Africa for two years in a row. Nairobi and Cape Town rank among the most advanced cities on the African continent on the smart city front. A smart city targets energy savings and adopts environmentally-friendly technologies, which helps promoting sustainable development. Smart cities leverage on technology and use the large amount of data their citizens generate every second to optimise resources, to connect people and to improve business and trading.
