SINGAPORE -- In Singapore, waiting for a bus has gone high tech.
In March, a new bus stop was put up along Singapore's trendy Orchard Road shopping district. Equipped with sensors and a ceiling camera, the structure collects data on commuters' flow and waiting time, as well as detecting possible suspicious items. The bus stop also has a cooling and purification unit on its roof, which keeps the air inside fresher and cooler than the surrounding area with its automobile exhaust fumes and tropical heat.
