Traffic Counts
DuPage County performs annual traffic counts at midblock and intersection locations. These counts have been organized into reports that are provided through the Division of Transportation's web page. Information provided includes turn movements, hourly
and directional travel, adjusted average daily counts and vehicle classification information. The link for that page is provided below:
The Illinois Department of Transportation also provides traffic information to the public. Links to the IDOT site can be found below:
Traffic Forecasts and Traffic Impact Assessment
DuPage County Transportation Planning performs regular updates to its traffic forecasting model. The traffic model is used primarily for assessment of development impact related to the Impact Fee program but has utility outside that program in terms of analyzing land use and development
impacts on corridor and sub-area traffic system performance. Transportation planning staff regularly performs site related traffic impact assessment and traffic signal system analysis on County Highways and will review private traffic impact assessments related to access and signal permits. For more
details on access permits and requirements, please see the
DOT Permitting page.
Transportation System Performance Measures
DuPage County staff performs regular evaluations of its highway system and produces reports on travel time, delay, intersection and roadway levels of service and more.
