چکیده
A Bayesian updating model is developed to capture the mechanism by which travelers update their travel time perceptions from one day to the next in light of information provided by Advanced Traveler Information Systems (ATIS) and their previous experience. The availability and perceived quality of trac information are explicitly modeled within the proposed framework. The uncertainty associated with a driver's travel time estimate is modeled in a stochastic dynamic framework and is incorporated in a travel choice model. Each driver uses a disutility function of perceived travel time and perceived schedule delay to evaluate the alternative travel choices, then selects an alternative based on the utility maximization principle. The perception updating model and the choice model are integrated with a dynamic trac simulator (DYNASMART). Empirical results from the simulation experiments and their implications are also presented. # 1998 Elsevier Science Ltd. All rights reserved.

Over the next few years, driver behavior should become more informed with the advent and deployment of in-vehicle navigation systems. This paper analyzes systems that provide the driver the fastest path between his or her current location and final destination, updated in real-time to consider recurring and nonrecurring congestion. The traveler s full cost per trip is a bundle comprised of both...

Third-generation personal navigation assistants (PNAs) (i.e., those that provide a map, the user's current location, and directions) must be able to reconcile the user's location with the underlying map. This process is known as map matching. Most existing research has focused on map matching when both the user's location and the map are known with a high degree of accuracy. However, there are ...

Traffic flow control in automated highway systems (AHS) is addressed. A link layer controller for a hierarchical AHS architecture is presented. The controller proposed in this paper stabilizes the vehicular density and flow around predetermined profiles in a stretch of highway using speed and lane changes as control signals. Multiple lane highways in which vehicles have different destinations a...

Increasing congestion on freeways and problems associated with existing detectors have spawned an interest in new vehicle detection technologies such as video image processing. Existing commercial image processing systems work well in freēowing trac, but the systems have diculties with congestion, shadows and lighting transitions. These problems stem from vehicles partially occluding one anot...

Various combinations of advanced public transportation systems (APTS), including advanced transit information, demand responsive transit, and personal rapid transit, are evaluated by applying traditional travel and emissions criteria as well as consumer welfare and equity criteria. A state-of-the-practice regional travel demand model is used to simulate the travel eects of the APTS technologie...
