Transportation agencies have invested in extensive infrastructure for vehicle detection and speed estimation. Although knowledge of vehicle speeds helps characterize traffic flow, vehicle accelerations can lead to better characterization. Vehicle accelerations are important in designing signal timings with respect to yellow intervals and green extensions for dilemma zone protection. Vehicle acceleration...
The distribution of travel times over a link in a transportation network can be estimated by observing the actual travel times of individual vehicles traversing the link and creating a histogram of the observations. The fundamental building block of travel time estimation is the re-idenfication of vehicles. A variety of techniques can be used for re-identification, but this paper focuses on electromagnetic...
