Measuring Improvements in the Movement of Highway and Intermodal Freight
Section 2 reviewed and summarized types of freight performance-measures presented in prior studies and investigations. This section indicates which of the specific measures appear to be most promising for use by FHWA. It recommends the following limited set of measures for further analysis and development by FHWA:
Cost of highway freight per ton-mile
Cargo insurance rates
Point-to-point travel times on selected freight-significant highways
Hours of delay per 1,000 vehicle miles on selected freight-significant highways
Crossing times at international borders
Condition of connectors between NHS and intermodal terminals
These recommendations were developed based on a two-stage evaluation process:
Initial Screening - Potential indicators were screened and grouped into four general categories: 1) potentially valuable (first-tier) indicators; 2) second-tier national indicators; 3) corridor or facility measures; 4) not-useful measures.
2) Criteria-based Evaluation — The first-tier indicators identified in step 1 were further evaluated and a small set are recommended as meriting further development by FHWA.
This section summarizes the findings from the initial screening analysis of potential indicators. Potential indicators were grouped into the following categories:
Potentially Valuable (First-tier) Indicators — These indicators were judged as potentially valuable as national indicators based on an initial screening analysis.
Second-tier Indicators— These indicators have a definite bearing on freight performance but are limited in some way, so they were not recommended for further development; many of these measures may already be available to FHWA.
Corridor or Facility Measures — These indicators are potentially good measures of freight performance but are specific to a particular corridor, site, or facility (e.g., intermodal terminals). They were viewed as inappropriate for FHWA as national indicators but may be useful at other levels.
