English Abstract The expected growth in car use of 70% in the period
1986-2010 indicates that measures are necessary to stop further worsening of
environmental conditions. Since 1987 Dutch local authorities with more than
40.000 inhabitants may take part in the "environmental traffic map project"
(VMK project) to help deal with local environmental problems caused by
traffic. The Dutch National Institute of Public Health and Environmental
Protection (RIVM) uses the data from these VMK's to estimate the extent of
guideline exceedances as well as to get a survey of air quality in Dutch
towns and cities. This report summarizes the results and conclusions of
RIVM's participation in the VMK project.
