TomTom, the Dutch manufacturer of automotive navigation systems recently released the results of its annual TomTom Congestion Index.

The company’s congestion index aims to provide the general public, industry and policy makers with unique and unbiased information about congestion levels in urban areas. The methodology used in coming up with this index compares travel times during non-congested periods with travel times in peak hours in select cities all over the world.

TomTom takes into account local roads, arterials and highways and all their data is based on actual GPS based measurements for each city. The sample size is expressed in total number of measured kilometres per period. TomTom’s traffic database contains over six trillion data measurements and is growing by five billion measurements every day.

And if we look at last year’s Congestion Index, Sydney is listed in the top 10 most congested cities in the world with Australians spending up to 92 hours a year caught up in peak hour traffic. Other highly congested areas in Australia include Perth and Melbourne with a congestion index of 33% and 28% respectively.

Moreover, Sydney was the only city in the region to be listed in the top 10 most congested global cities, measured by index where it tied with Los Angeles, Stuttgart, Paris and Rome at 33%.

TomTom’s Congestion Index, including individual continent and city report can be found on the company website.
