This paper describes a general framework called Hybrid Dynamic Mixed Networks (HDMNs) which are Hybrid Dynamic Bayesian Networks that allow representation of discrete deterministic information in the form of constraints. We propose approximate inference algorithms that integrate and adjust well known algorithmic principles such as Generalized Belief(More)
The primary goal of activity-based models is a fundamental examination of the behavioral process that results in revealed travel behavior. To reveal this process, a new computer program, REACT! 1 , has been developed to collect data for a study of the determinants of travel and activity behavior in households. This data is inherently dynamic, since(More)

2 ABSTRACT This paper describes the initial testing and evaluation of one of the key components of the Testbed Real-time Integrated Control and Evaluation Prototype System (TRICEPS). TRICEPS is a software platform that facilitates the implementation and evaluation of a wide range of algorithms for traffic control and Advanced Transportation Management(More)
This paper describes a method for storing, modeling, and processing an individual's travel history collected with a GPS enabled device. The technique uses a general framework called Hybrid Dynamic Mixed Networks (HDMNs), which are Hybrid Dynamic Bayesian Networks that allow representation of discrete deterministic information in the form of constraints. We(More)
