The continued economic growth and urbanisation trends represent a growing challenge for cities. Rising traffic congestion is an inescapable condition in large and growing metropolitan areas across the world, costing as much as 1% to 4% of national GDP. In 2018, 11 of the top 15 cities with highest number of spent hours in congestion globally were European. Main urban regions of smaller countries like Belgium and Ireland are also reported to be seriously affected by the traffic congestion. Traffic congestion imposes massive costs on all government, transportation companies and drivers due to time loss, increased pollution rates, and higher incidence of accidents. Each year, congestion costs in Europe amount to €100 billion, about 1% of the EU’s GDP. Without effective action, the problem could worsen, with congestion costs projected to increase to €200 billion by 2050.
