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...

Over the past 10 years, operating expenses for Demand Responsive Transit have more than doubled as demand for this mandated service has expanded. Many advanced technologies and management practices have been proposed and implemented to improve the efficiency of the service; but, evidence for the...

In this report, the implementation in the SHIFT programming language of regulation layer control laws for the hierarchical California PATH Automated Highway System (AHS) is presented. The implemented regulation layer control laws are derived after the safe-feedback based maneuvers designed in...

This report summarizes an experimental effort in integrating and testing an automated vehicle lateral control system. The project, a cooperative effort between the California Partners for Advanced Transit and Highway ( PATH) Program and IMRA America, Inc., included a discrete roadway reference...

This report deals with the lateral guidance of vehicles, with focus on lane change maneuvers. Two approaches are presented for lane changes maneuvers. The first is to treat the maneuvers as a tracking control problem. A virtual desired trajectory (VDT) is used a tracking control approach. The...
