In May 1996, the FAA announced a new and innovative approach to reach a goal of "zero accidents," known as the Global Analysis and Information Network (GAIN). This would be a privately owned and operated international information infrastructure for the collection, analysis, and dissemination of...

In this report, the authors present a modified safe join trajectory for the regulation layer maneuvers of the hierarchical PATH Automated Highway System (AHS) architecture. This new design presents a more conservative behavior for the controlled platoon in a maneuver. The new trajectory reduces...

This research builds on the contributions of MOU 357, 3001 and task Order 4119 all of which focus on methodological and measurement issues in benefit cost assessments of ITS applications. The important contributions of this work are not only providing methods for calculating benefits and costs...

This paper develops an economic framework for developing strategies necessary to deploy networks, and applies the framework to the deployment of road pricing. The cost structure of highways are discussed. A graphical method for measuring welfare with road pricing is presented. The relationship...

In 2002, the City of Oakland, California implemented a scramble signal, at the intersection of 8th Street and Webster Street. Scrambles are a type of traffic signal that give pedestrians exclusive access to an intersection by stopping vehicular traffic on all approaches, allowing pedestrians to...

This report summarizes PATH ATMIS and Systems research for fiscal year 1998/1999. In each of the brief project descriptions we state the objectives of the project and outline its status and some of its principal results. These descriptions are not intended to be comprehensive or complete, but...

In this project (MOU 336),an initial phase of a field implementation was accomplished of the results of a previous research project (MOU 224),in which a vehicle reidentification algorithm based on loop signature analysis was developed using freeway traffic data.This algorithm was extended to...
