Due to the life-shortening effect, sitting is known as the new smoking. People stuck in a traffic jam are thus doubly disadvantaged: they spend time, and thus also reduce their life expectancy. This risk is particularly high in Mumbai, Bogotá or Lima. Due to the high traffic density in each of the three cities, around 60 percent extra time has to be planned for each route, according to an analysis by the Dutch navigation company TomTom.
The risk of congestion is increasing in many parts of the world: with newly registered vehicles (nearly 80 millions of new cars are sold every year) and booming deliveries of goods. Traffic jams thus stand for a strong economy. But in addition to the personal waste of time they also contribute significantly to air pollution.
Therefore, many cities take action: In Jakarta, cars can only be driven every two days. New Delhi announced that it would soon redesign important roads in a traffic-friendly way and make street parking more expensive. A city toll, as has long been the case in Singapore and London, is also being discussed from New York to Beijing. Although this makes driving more expensive - ideally, it also has a life-prolonging effect.
