The evaluation approach was to collect data to assess the impact of the traffic/incident management system on customer satisfaction, system efficiency, and traveler mobility in the corridor during incident conditions. A panel survey of drivers who commute northbound in the Study Area was established to which to administer a series of "incident" surveys to gain perspective on their perceptions of and satisfaction with traffic conditions in the corridor during incidents. To assess system efficiency and traveler mobility, ODOT provided volume, speed data, and secondary incident information for I-5, and TriMet (the public transit provider in Portland) provided speed data from bus probes along Barbur Boulevard.119
