In past reviews, we have looked at how congestion pricing reduces both congestion and improves air quality in the urban core. Today we  examine another approach, widely used in Europe over the last 20-30 years, which combines the removal of road capacity and adding pedestrian areas to the space freed up. The results from 70 case studies in European cities and New York City point to the many improvements and reduced congestion with examples from the UK, Germany, France, Denmark, Belgium and other countries. Vehicle emissions in downtown areas decreased by 15-30% one year after road removals.
