Performance Measurement Framework for Highway Capacity Decision Making

TRB / SHRP2 Program

Overview

This report describes a performance measurement framework that supports the collaborative decision-making framework for additions to highway capacity. Five broad areas of performance are identified: transportation, environment, economics, community, and cost. The report devotes a chapter to each of the five performance areas, covering for each the background literature, key findings, identification of performance factors, a selection of measures for each factor, and case study references. Under these headings, 17 performance factors are identified and each is linked to key decision points in the decision framework. The measures and performance factors were assembled from interviews, case studies documented in the report, other SHRP2 work, and the literature on the subject. Appendices provide detailed write-ups of case studies conducted as part of the project and a discussion of data sources, data gaps, and high-value data investment opportunities.

A companion web tool was also developed. The web tool is intended to be a permanent and dynamic resource and will be updated as additional SHRP 2 and other research is completed.

While the purpose of the performance measurement framework is to establish a systematic approach, the emphasis of the research was on less-developed areas of measurement, such as climate change, ecosystems, environmental health, archeological and cultural resources, and travel time reliability. Measures for each factor are provided along with a discussion of data needs and data gaps.
