Reduced Emissions with Dynamic Speed Limits

On the European route E18 through Danderyd just north of Stockholm, variable speed limit signs have been implemented on a stretch of road of approximately 2 km. Particular matter (PM10) and nitric oxide (NOx) concentration in the air have been measured. The collected data will periodically be analyzed. The purpose is to gain greater knowledge about the connection between vehicle speed and the concentration of pollution in the air. Hopefully, by means of dynamic speed limit signs it will be possible to lower the concentration of air pollution caused by traffic. Previous research at the Swedish National Road and Transport Research Institute (VTI) and the Department of Applied Environmental Science, Stockholm University (ITM) clearly indicate that emissions decrease as vehicle speed is lowered. Measurements of PM10 and NOx will continue until May 2010. A final report on the project is due by October 2010. If a statistically significant correlation is evident an inception to model dynamic speed limits considering hour, day and season will be carried out and dynamic speed limit signs will be implemented permanently. This can be of great help in setting standards for future society planning.
