Development Of A Multi-Modal Travel Demand Module For The Regional Strategic Planning Model, Huajie Yang

PSU Transportation Seminars

Part of the Student Presentations from TRB

Integrated land use and transportation models have evolved along a spectrum with simplistic sketch planning models on one end and sophisticated microsimulation models on the other. While each type of these models has its niche, they are largely unable to balance the flexibility and realism of microsimulation and the speed and interactiveness of simple models. The Regional Strategic Planning Model (RSPM) aims to fill this gap by taking a microsimulation approach but making other simplifications, to model first-order long-term outcomes of land use and transportation quickly. It takes into consideration the underlying uncertainties …

Transportation Cost Index: A Comprehensive Performance Measure For Transportation And Land Use Systems And Its Application In Or, Fl, And Ut, Liming Wang, Jenny H. Liu

TREC Final Reports

MAP-21 and state laws are placing increasing emphasis on using comprehensive transportation performance measures that include mobility, safety, economy, livability, equity, and environmental to guide transportation decision-making. One of the toughest challenges keeping DOTs and MPOs from adopting comprehensive measures in the decision process is the lack of performance measures allowing consistent comparison of multimodal performance over time and across geographic areas. This project advances a transportation cost index (TCI) initially proposed by Oregon DOT from a proof-of-concept stage to implementation and operational use at the state, MPO, and community levels. After pilot tests and early adoption in Oregon, we …

Track Time And Monetary Costs Of Transportation As A Comprehensive Performance Measure: Development And Application Of Transportation Cost Index, Liming Wang

PSU Transportation Seminars

As federal and state policies place increasing emphasis on using comprehensive transportation performance measures to guide transportation decision making, there is a gap in such measures of transportation and land use systems. This seminar reports the results from a research project aiming to fill the gap in the type of applications and policy areas covered by existing measures. Modeled after the popular Consumer Price Index, the project refines and develops a transportation cost index (TCI) measure for transportation and land use systems by tracking the time and monetary costs of transportation for households as they travel to satisfy their daily …

Transportation Cost Index As A Performance Measure For Transportation And Land Use Systems: New Approaches And Applications, Liming Wang, Huajie Yang, Jenny H. Liu

Urban Studies and Planning Faculty Publications and Presentations

This research aims to fill gaps in existing multi-modal performance measures for transportation and land use systems:

1. As a supplement/replacement of traffic-centric measures such as LOS, travel delay;
2. Recent federal and state legislations put more emphases on using of performance measures in transportation planning & operation: MAP-21, Oregon Job and Transportation Act (OJTA);
3. Existing performance measures for transportation and land use systems, although now numerous, have their own limitation (Table 1), and leave important aspects and policy areas uncovered, for example, the balance of transportation investment between different modes and across geographical areas as mandated by OJTA

Webinar: Transport Cost Index: A New Comprehensive Performance Measure For Transportation And Land Use, Liming Wang

TREC Webinar Series

Recent federal and state policies are placing increasing emphasis on using comprehensive transportation performance measures to guide transportation decision making processes covering policy areas ranging from mobility, safety, economy and livability, to issues of equity and environment. While it is relatively easy to build consensus on mobility measures that center on the transportation system alone, it is much harder for performance measures to incorporate both transportation and land use, loosely defined as accessibility measures, even with continuous efforts to catalog and design such measures.

Two projects at PSU sponsored by Oregon DOT and National Institute of Transportation Communities (NITC) aim …
