The local government recently closed the city centre to motorised traffic, creating an extensive Urban Ecological Zone that has been gradually expanded so that today it covers more than 100,000 m2. Walking distances for pedestrians have been shortened with the installation of new bridges and the introduction of free of charge electric vehicles. The city has modified the traffic regime on the main traffic artery by limiting motorised traffic and giving priority to pedestrians, cyclists and public transport. It has significantly impacted the air quality of existing transport routes in the city.
