Today we review research into improved modelling of emissions from congested traffic which takes into account instantaneous starts and stops instead of assuming a constant speed of vehicles. The results indicate that previous mobile transportation pollution models may underestimate emissions by as much as 60%.and this has large potential consequences for environmental impact assessments of large transportation projects, as well as for regulating or reducing emissions from currently congested cities.
