Using data collected from users around the globe, TomTom has created a traffic index measuring how long it takes to drive distances throughout the day and during peak periods compared with driving times during non-congested periods, resulting in a total average percentage increase in travel time, MarketWatch.com reports.
According to the data, Dublin commuters spend 35% more time traveling during congested periods. The delay per hour for driving during a peak period is 43 minutes, and the delay per year with a 30-minute commute is 96 hours.
Here is the complete list of cities with the worst traffic in the world:
