The average commuting time in most European countries is 38 minutes, as opposed to 25 minutes in the United States. This figure goes as high as 45 minutes in the United Kingdom, the most congested commuting of Europe. It is however in Asia cities that the daily commuting time tends to be the highest, mainly the outcome of associated high congestion and density. Paradoxically, commuting times tend to be higher when public transit has a higher share of total trips. Public transit commuting trips are on average 30 to 40% longer time-wise compared to automobile trips.
