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 to to develop and evaluate Transport Cost Index (TCI), a comprehensive performance measure for transportation and land use, in order to fill important gaps in popular accessibility measures: 

  1. TCI is a composite indicator that is able to present an overall picture of a community’s accessibility, while at the same time is relatively easy to interpret for policy...

Using Multimodal Performance Measures to Prioritize Improvements on US 101 in San Luis Obispo County

The US 101 Corridor Mobility Master Plan in San Luis Obispo was a two-year planning effort that evaluated the 70 mile corridor on 12 performance measures. This collaborative effort was led by the San Luis Obispo Council of Governments (SLOCOG).

Performance based planning is becoming more important for agencies receiving State and Federal funding. Smaller, rural regional agencies will have to find ways to collect, report, and use performance metrics with limited resources. SLOCOG's first performance-based planning effort was the US 101 Corridor Mobility Master Plan, funded through a State grant.

Funding for this project came from a Partnership Planning Grant awarded by the California Department of Transportation (Caltrans) along with SLOCOG matching funds. The study team — made up of staff from 6 cities, the county, SLOCOG, Caltrans, the Air Pollution Control District, and the Regional Transit Authortiy — evaluated the corridor using 12 performance metrics and input from the public. 140 project alternatives were evaluated on several measures of effectiveness to determine which improvements were more beneficial to the corridor. SLOCOG used the results of this study to...
