Delhi odd-even scheme starts on November 4: How the world's top cities tackle pollution, traffic woes

In a bid to curb air pollution in Delhi in the aftermath of Diwali, Arvind Kejriwal-led Aam Aadmi Party government has brought back the odd-even policy for vehicles from November 4 to 15. This is not the first time the Delhi government will try the road-rationing method. It implemented the odd-even policy twice in 2016, from January 1-15 and April 15-30.

But the odd-even scheme is not the only way used to curb vehicular traffic to contain pollution levels across the world. CNBCTV18.com has compiled a list of various mechanisms authorities across the world employ to deal with traffic problems and air pollution.

To prevent traffic congestion and pollution problems faced by European cities after the industrial revolution, Le Corbusier, the principal architect of Chandigarh, planned the city based on the gridiron. Defined by a system of seven types of roads, also known as the 7Vs, traffic circulation in Chandigarh was designed to provide safe mobility to children and pedestrians within and between the sectors, while permitting efficient vehicular transportation.
