Limited traffic zone

Limited traffic zone (LTZ) is type of restricted traffic area found in many historic European city centres where non-residents and unauthorized vehicles are prohibited from driving at certain times. These areas are relatively abundant in Italy, where they are called zona a traffico limitato (ZTL), but they also exist in Spain, Portugal, France and Poland with different names. Around 350 Italian cities have LTZs, and 250 have low-emission zones (LEZs), usually enforced with camera surveillance. They help protect historic city centres from excessive traffic, which would otherwise make the city less attractive. They can also be aimed at limiting pollution levels or at increasing administrative revenue by paying an urban toll.
