Traffic Index 2018

The Traffic Index 2018 was published by TomTom, a company offers traffic solutions, uses location technology to collect traffic information, and has been publishing city rankings for eight years. The index ranks 403 cities across 56 countries.

How the Index was measured?

It takes into account:

  • Congestion which is defined in terms of the additional time taken to reach a destination as opposed to when the road would have been clear of traffic.
  • Average times for actual trips were worked out by establishing a baseline of travel times during uncongested conditions across each road segment in each city
  • The index also factors for peak hours, accidents, inclement weather, construction work and all other factors which likely to cause disruptions. The statistics are calculated using GPA data from navigation devices, in-dash systems and smartphones.

Findings of the Study

  • About 75% of the cities part of the 2018 index had increased or stable congestion levels between 2017 and 2018 and only 90 cities showed a measurable decrease.
  • Globally, traffic congestion is rising which is both good, and bad. It s good because it indicates a strong global economy, but the flip side is drivers wasting time sitting in traffic which is also resulting in a huge environmental impact.

  • Christmas Day resulted in the least traffic congestion globally in 2018.
  • An individual stuck in traffic in 2018 could have completed listening to one audio-book per week.
Mumbai and Delhi
  • Mumbai was the most traffic-congested city in the world for the second straight year and Delhi at fourth place.
  • The traffic congestion during morning and evening peak hours varies between 73% and 102% in the Indian cities of Mumbai and Delhi.
  • August 8 was the worst day to drive in Delhi, owing to the movement of VIPs and restrictions put in place in the run-up to Independence Day celebrations with traffic congestion of about 83 per cent.
  • August 21 was the worst day on the road In Mumbai with traffic congestion of 102 per cent owing to heavy showers and work on multiple Metro rail lines.
  • The traffic flows most freely between 2 am and 5 am in both cities and the least congestion last year happened on March 2 (-16%), the second day of Holi.
