Multi-Modal Performance Measures in Oregon: Developing a Transportation Cost Index Based Upon Multi-Modal Network and Land Use Information.

摘要

Transportation Cost Index is a performance measure for transportation and land use systems originally proposed and piloted by Reiff and Gregor (2005). It fills important niches of existing similar measures in term of policy areas covered and type of applications. The goal of this research project is to move TCI from prototype towards implementation and application by establishing robust definitions of travel market baskets and robust methods for calculating transportation costs. After reviewing literature, we propose two approaches of defining travel market baskets, namely the cluster-based approach and the survey-based approach, and one method of calculating travel costs. We develop these approaches and implement them in R as an open source project. We then apply TCI to various regions, in particular Portland and Corvallis in Oregon, to showcase its scalability and applicability.
