In 2003, London adopted a program of congestion pricing that now places a roughly $17 (£11.50) daily fee on motor vehicles entering central London. The effort was expected to reduce car traffic, air pollution, and emissions in the area, and has since been lauded as a major success.
Beyond these benefits, congestion pricing has also saved lives by reducing the number of fatal traffic crashes caused by cars, increasing physical activity from cycling and walking, and limiting exposure to air pollution.
A new study by researchers in the United Kingdom shows that, since the introduction of the congestion charge, there have been 30 fewer monthly traffic crashes in central London—a 40 percent decline—and a comparable fall in fatalities and injuries. This reinforces the conclusions of a previous study from 2006as well as global research that transport pricing policies can bring important safety benefits.
