This work poses the problem of estimating traffic signal phases from a sequence of maneuvers recorded from a turning movement counter. Inspired by the part-of-speech tagging problem in natural language processing, a hidden Markov model of the intersection is proposed. The model is calibrated from maneuver observations using the Baum-Welch algorithm, and the(More)
In Illinois, there were 217 wrong-way crashes on freeways from 2004 to 2009, resulting in 44 killed and 248 injured. This research project sought to determine the contributing factors to wrong-way crashes on freeways and to develop promising, cost-conscious countermeasures to reduce these driving errors and their related crashes. A thorough literature(More)
While parking is an important issue in transportation engineering and planning, little research has examined the use of new parking information technologies on rural communities. The 3 researchers have used Clemson University campus, in South Carolina, as a case study to determine the ability of roadside parking information systems for reducing delay,(More)
This work poses the problem of estimating traffic signal phases from a sequence of maneuvers. We model the problem as an inference problem on a discrete-time hidden Markov model (HMM) in which maneuvers are observations and signal phases are hidden states. The model is calibrated from maneuver observations using either the classical Baum-Welch algorithm or(More)
