WSDOT Traffic Volume Map Application

The WSDOT Traffic Volume map is an application that allows users to view the WSDOT Annual Average Daily Traffic (AADT) via your web browser. It replaces the Traffic Flow Map historically provided in the department’s Annual Traffic Report (ATR).  It also augments the ATR by providing AADTs for more traffic counting locations than found in that report.
