Modelling Emissions from Stop-and-Start Traffic Congestion


A congestion sensitive approach to modelling road networks for air quality management (Abstract, James O’Brien; Anil Namdeo; Margaret Bell; Paul Goodman, Int. J. of Environment and Pollution, Dec. 2014)
Also discussed here: Stop-start driving in city centres creates higher pollution levels (Phys Org, Dec. 12, 2014)

And here: New regional traffic model to combat urban road congestion (Phys Org, Jan. 9, 2014)

And here:  Verkeersvoorspellingen met modellen: een voorspelling over modellen (in Dutch language) (3 page pdf, Victor L. Knoop and Serge P. Hoogendoorn, Nationaal verkeerskundecongres, 6 Nov. 2013)

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.
