The current research presents the "10-year energy cost" label as an effective nudge to increase energy efficient choices by retail consumers. Its efficacy is demonstrated in both lab and field studies (Studies 1a and 1b) and compared to other energy labels (Studies 4 and 5). The current work...

The objective of this paper is to review our recent research completed on the determination of the probability distribution of the time of breakdown on a freeway. The methodology applied was unique, in that, it applied Markov chains to develop the probability distribution of the time of...

Trucks have an effect on the quality of traffic flow on freeways. The passenger car equivalency of a truck represents the number of passenger cars that would have an equivalent effect on the quality of the traffic flow. This research estimated truck passenger car equivalents using simulation,...

Travel time is widely recognized as an important performance measure for assessing highway operating conditions. There are two methods for obtaining travel time: direct measurement, or estimation. For the latter, previously developed models tend to underestimate travel times under congested...

Freeway weaving areas are those formed when the paths of two or more traffic streams cross, i.e., when a merge area is closely followed by a diverge area, and the two are joined by an auxiliary lane. Previous research on weaving areas has mostly focused on developing methods for estimating...
