Urban Vehicle Access Regulations (UVAR) refer to policies and measures that control vehicle access to specific urban areas to reduce congestion, improve air quality, and promote sustainable mobility. These regulations include low emission zones, zero emission zones, tolling/congestion charging, pedestrian areas, parking schemes and limited traffic zones. 

Application

In practice, UVARs are implemented by cities to manage traffic flow and reduce environmental impact. For example, low-emission zones restrict access to vehicles that do not meet specific emission standards, encouraging the use of cleaner vehicles. Cities also designate car-free zones or restrict access based on vehicle type, size, or purpose to prioritise pedestrians, cyclists, and public transport.
