Measuring Arterial System Performance
The 2012 federal transportation authorization - the Moving Ahead for Progress in the 21st Century Act (MAP-21) - places several new performance measurement and reporting mandates, including arterial system performance, on state transportation departments. The Virginia Department of Transportation (VDOT) is also interested in further, detailed system-performance measurement, as reflected in its current business plan goals. This research project will support VDOT in achieving compliance with these MAP-21 mandates and in making more informed operations and resource-allocation decisions. Specifically, this study will focus on identifying candidate arterial-system performance measures and data needs; exploring details of corridor segmentation for analysis and reporting; assessing impacts of missing data on performance measures; and conducting pilot analyses to calculate measures from actual Virginia data.
