The top three worst cities were Moscow, Istanbul and Bogota
Sydney was 13th, Melbourne was 17th and Brisbane was 24th.
Surprisingly Los Angeles is not in the top 25 nor is Dublin which had the slowest travel speed of 9.5 km/hr in their city centre.
They don’t just measure the worse travel speeds. One factor that they take into account is the difference in travel speeds on the roads between the peak time and the non-peak time which is a measure of just how bad the peak period is.
