ABSTRACT: Transportation sustainability is of increasing concern to professionals and the public. This project describes the modeling and calculation of sustainability performance measures in a transportation data archive. The purpose of these measures is to assess the sustainability of Portland, Oregon's metropolitan freeway system. The measures were developed to be part of, and use the data from, the PORTAL regional transportation data archive at Portland State University. They estimate vehicle emissions (CO, VOC, NOx, and CO2), fuel consumption, cost of time delay, and person mobility (travel in person-hours and person-miles, and delay in person-hours). Methods for modeling and necessary data are described. In the future, plans call for integrating these measures into the PORTAL web interface to expand the types of performance measures used for regional transportation planning and operations.
