This study investigates issues concerning the implementation and impacts of lateral guidance/control systems and the phased implementation of these systems in exclusive-access High Occupancy Vehicle (HOV) lanes. The study is divided into 5 volumes. The objectives of each volume are as follows:...

This manual provides a brief introduction to four classes of software objects developed to help a user create and test interfaces using these objects in the Interface Builder application environment. The Knob, Dial, Alert Light, and Map object classes presented here represent the beginnings of a...

TravInfo is a Field Operational Test (FOT) in advanced traveler information systems (ATIS) for the San Francisco Bay Area sponsored by the Federal Highway Administration (FHWA). The project involves a public/private partnership which seeks to compile, integrate and broadly disseminate timely and...

The focus of this research effort is the study of driver behavior in the presence of real-time traffic condition information. The methodology adapted for this research involves three parts: development of a theoretical model for driver behavior under Advanced Traveler Information Systems (ATIS),...
