New Delhi may pride itself on its wide roads, which are the envy of other Indian metros but almost all of Delhi's respondents said that traffic had negatively affected their health and half said that driving makes them angry.
IBM's 2010 Commuter Pain Survey polled 400 drivers in each of 20 major cities in six continents. It made a Commuter Pain index based on the survey result.
The result ranks the emotional and economic toll of commuting in each city on a scale of one to 100 along 10 indicators, including commuting time, driving-related stress and the impact of traffic on work.
Beijing and Mexico City scored 99 out of 100 in IBM's commuter pain index, followed closely by Johannesburg, Moscow and New Delhi.
IBM charged most commuter troubles on the failure of infrastructure to keep pace with global economic activity.
Traditional solutions such as building more roads was not enough to cope with the surge of traffic in rapidly growing cities, said Naveem Lamba, IBM's global industry chief for intelligent transportation.
