Extreme levels of congestion, gridlocked streets, and poor air quality have had a negative impact on road safety, economy, and health of people living and working in cities. Our congestion charging and low-emission zone solutions address these challenges by facilitating a non-stop flow of traffic.

Congestion charging is a fee levied on cars and most vehicles that drive in designated congestion zones during certain times. The goal is to influence driver behavior in an attempt to curb peak travel times. Low-emission zones (LEZ) take it a step further by prohibiting all vehicles that do not meet permitted emission level requirements.

Traffic exhaust gases are a major contributor to high volumes of fine particulate matter -NOx and PM2.5- that cause air pollution, including smog. Using the polluter-pays principle, authorities and road operators can charge or fine vehicles that exceed emission standards.

Separately and collectively, congestion charging and low-emission zone schemes serve to reduce the volumes of traffic and improve air quality.
