Foreword The ability to model vehicular flows in traffic networks under real-time information, and to provide system users with route guidance information, constitute essential methodological components required to support the successful operation of Advanced Traveler Information Systems and Advanced Traffic Management Systems. This report describes the(More)
The traditional surrogate measures of safety (like number of vehicles in dilemma zone) fail to quantify the risk of crash. Traffic conflict has been proposed as an improved surrogate measure of safety for operations at isolated intersections to quantify the risk. This paper develops a dilemma zone hazard function estimating procedure to obtain the(More)
Dilemma Zone Design as a Marginal Cost-Benefit Problem" (2007). One control objective at high-speed isolated intersections is to provide safe phase transition by minimizing the occurrence of high-speed vehicles in the dilemma zone before the phase is terminated. An upper limit for extending the green (maximum green time) is used to avoid an indefinite(More)
This paper focuses on the relationship between the content of VMS messages and driver route diversion rates. Presumably, if different message contents to describe the same situation prompt different diversion rates, then message content can be used as a control variable by the traffic controller to generate favorable network conditions in the real-time(More)
Due to similarities in terms of network structure and interactions among them, most infrastructure systems can be viewed as coupled layers of a generalized transportation network in which the passenger, freight, data, water, and energy flows are the commodities in the different layers. The coupling is due to the varying degrees of interactions among these(More)
The problem addressed here involves a controller seeking to enhance traffic network performance via real-time routing information provision to drivers while explicitly accounting for drivers’ likely reactions towards the information. A fuzzy control modeling approach is used to determine the associated behavior-consistent information-based network control(More)
