The concept of a congestion threshold is embedded in the definition of “congestion.” Two basic approaches exist in current practice for setting the congestion threshold. One common approach uses the free-flow or unimpeded conditions. Another appr

This paper presents a fully Bayesian multivariate approach to before-after safety evaluation. Although empirical Bayes (EB) methods have been widely accepted as statistically defensible safety evaluation tools in observational before-after studies fo

A congestion index that is keyed to the differences in actual versus desired travel times for various types of roadways is described. The suggested index provides a continuous scale for assessing the amount of congestion incurred. It encompasses a wi

Transportation systems analyses have been evolving as the decision context for improvement projects and programs has changed. The increased emphasis on the movement of persons and goods, and a recognition of the importance of system performance measu

Procedures are presented for measuring and estimating roadway congestion levels. An assessment of users, uses, and audiences indicates a need for congestion measures that are understood by nontechnical audiences, yet are rigorous enough for technical

Measuring the effects of transportation system improvements has long been a challenge. Two estimates—the congestion index method and the travel delay method—are used to produce a range of possible benefits resulting from the implementation of tra

Basic reliability issues are addressed in this study, which is not concerned with average travel times, but rather ways of describing travel times that reflect the uncertainty in the amount of time required to travel between two points. Some of the u

This paper presents a GIS-based procedure to estimate congestion index (CI) at the highway link level. Using the 1995 traffic assignment data for the Lubbock, TX area, the exercise produces CI values at the network link level. These disaggregate meas
