Traffic congestion has a negative impact on the economy (by decreasing productivity) and on the quality of peoples lives. Road users experience delay and stress and environmental pollution increases (more noise, more emissions and more fuel consumption).
What are the effects of traffic congestion?
Traffic congestion adversely impacts quality of life and economic productivity in metropolitan areas. It increases fuel consumption, the cost of traveler and freight movement, the number of crashes, and tailpipe pollutants harmful to human health.
How does congestion affect pollution?
Traffic congestion increases vehicle emissions and degrades ambient air quality, and recent studies have shown excess morbidity and mortality for drivers, commuters and individuals living near major roadways. Presently, our understanding of the air pollution impacts from congestion on roads is very limited.
How does traffic congestion affect pollution?
Road transport accounts for a significant portion of air pollution in cities and towns, causing serious pollution problems like carbon monoxide and smog. Traffic fumes contain harmful chemicals that pollute the atmosphere. Road traffic emissions produce greenhouse gases that contribute to global warming.
Why does traffic congestion affect the economy?
But it is sobering to think that traffic congestion is costing the national economy $16.5 billion in lost productivity each year, according to the governments own bureau of Infrastructure, Transport and Regional Economics. It makes economic sense to act to reduce these losses.
