Supporting the daily activity of Oregon businesses and residents is key to the mission of the Oregon Department of Transportation (ODOT). Policy-makers must make strategic choices about how and where resources are spent. Effective solutions require an understanding of how travel affects people’s lives and the economy. As Oregon grows, congestion in urban centers rises, which impacts mobility. When making transportation choices, businesses and people consider cost, time, safety, and reliability. It is important to understand the economic motivations behind travel, mobility and congestion in order to develop effective policies and strategic investment plans. The purpose of this study is 3-fold:
1. Identify factors affecting transportation demand in a manner that informs policy development;
2. Quantify system use, measure how much the system is used, and provide context with respect to system capacity and condition;
3. Measure the quality of system performance, identify how well the system functions and report congestion issues.
