Benefit Summary HTML

The Washington State Department of Transportation (WSDOT) placed data collection devices on some of the most heavily used sections of the Puget Sound region's freeways. The devices were installed on SR 512 and I-5 in the Olympic Region. The data collected from those devices were displayed in two places on WSDOT's website, on the state's 511 system and through the mobile phone application that WSDOT supports. The information was also distributed to private sector firms that distribute their own travel information via platforms ranging from conventional radio broadcasts to smart phone applications.
