In Paris, the zone 30km/h will expand

In order to improve the Parisian air quality, various measures will be introduced in addition to the existing ZCR zone. One is the introduction of 30 km/h zones where 50 km/h were allowed until present. The 30 km/h zones shall make the traffic more fluid and, as a result, reduce the pollutant emissions. The low speed zones should include 85% of the capital’s roads until 2020.
