1. Abstract Transportation sustainability is of increasing concern to professionals and the public. This project describes modeling, calculation, and necessary data for sustainability performance measures in a regional transportation data archive. Objectives Establish modeling and calculation procedures for sustainability performance measures that: Specifically address economic, environmental, and social sustainability Can easily be incorporated into the data archive Are useful for regional performance reporting, planning and operations Data The primary data source was the PORTAL regional transportation data archive at Portland State University Approximately 600 inductive loop detectors on Portland's metropolitan freeways, incident and VMS data, one year’s worth of stop-level bus data and hourly weather conditions Conclusion The “green” performance measures described in this project will add a new dimension to the PORTAL data archive. They offer key transportation system sustainability indicators that can readily be calculated from existing PORTAL data.

2. Greening PORTAL: Adding Sustainability Performance Measures to a Transportation Data Archive Alexander Y. Bigazzi and Dr. Robert L. Bertini, Portland State University Fuel Consumption Person Mobility Delay Cost Fuel Consumption was calculated from MOBILE 6 fleet fuel economy estimates (around 17mpg). These are not speed-based estimates, but depend primarily on fuel and emissions programs and the vehicle fleet. Delay cost calculations were based on auto/truck splits, ODOT time value estimates, and traffic data. Auto and truck time values for 2008 were around $18 and $27, respectively, per vehicle-hour. Person-miles of travel, person-hours of travel, and person-hours of delay were calculated from auto/truck splits, ODOT vehicle occupancy estimates, and traffic data. Auto and truck occupancies were around 1.55 and 1.07, respectively.
