Longitudinal Control Development For IVHS Fully Automated And Semi - Automated System: Phase III

Hedrick, J. K.
Garg, V.
Gerdes, J. C.
Maciuca, D. B.
Swaroop, D.
1997

This report focuses on longitudinal issues regarding modeling and control of vehicles in an Intelligent Transportation Systems (ITS) setting. Specifically, the report addresses the issue of vehicle control in an automated highway system, brake actuation and brake control. Recent research findings in the area of automated vehicle platooning on isolated lanes of an automated highway are included. Performance specifications, control system architecture, vehicle control algorithms, actuator and sensor specifications and communication requirements are also discussed. The report also addresses...

Development and Implementation of a Vehicle-Centered Fault Diagnostic and Management System for the Extended PATH-AHS Architecture: Part I

Yi, Jingang
Suryanarayanan, Shashikanth
Howell, Adam
Horowitz, Roberto
Tomizuka, Masayoshi
Hedrick, Karl
Alvarez, Luis
2002

The purpose of this project is to extend and integrate existing results on fault diagnostics and fault management for passenger vehicles used in automated highway systems (AHS). These results have been combined to form a fault diagnostic and management system for the longitudinal and lateral control systems of the automated vehicles which has a hierarchical framework that complements the established PATH control system. Furthermore, the fault diagnostic module effectively monitors the sensors and actuators required for longitudinal and lateral control, while the fault handling module...

Methods Of Analysis Of Ivhs Safety: Executive Summary

Hitchcock, Anthony
1992

This report presents the executive summary to a study on developing and demonstrating methods by which the safety of Intelligent Vehicle Highway Systems (IVHS) can be assured, assessed and evaluated. Safety considerations were studied for automated freeways, driver aids and copilots. Management and policy issues are briefly discussed in conclusion.

Lessons in Network Management: Cross-Industry Comparisons and Implications for ITS Development

Horan, Thomas A.
Reany, William
2002

This report provides an historical and case study analysis of policies aimed toward the management of complex systems, with specific reference to the role of public policy and technology in balancing surface transportation system demand and supply. Three case studies form the crux of the paper energy management, airport management, and Internet growth. Lessons from these case studies are then applied to the circumstance of ITS deployment to manage surface transportation in California. Following an introductory section (1), section 2 provides an historical analysis of the forces with have...

Pedestrian and Bicycle Safety Evaluation in a SMART Corridor

Ragland, David R., PhD
O’Connor, Terri
2008

The San Pablo/I-80 corridor is a “SMART” transportation corridor that extends about 20 miles along the eastern shore of the San Francisco Bay. The corridor uses Intelligent Transportation System (ITS) technologies to increase and enhance transportation mobility.The goal of the SMART Corridor Plan was to improve vehicle mobility throughout the corridor. Since the plan focused almost exclusively on vehicular traffic, achieving these goals has the potential to raise the risk of injury to pedestrians and bicyclists without thorough analysis of the overall effects of the SMART corridor...

Framework for Developing a Regional System Architecture for Intelligent Transportation Systems

Rodriguez, DA
Sussman, JM
1997

Defining an architecture for intelligent transportation systems (ITS) at the regional level, where most ITS deployment occurs, is constrained by jurisdictional, institutional, financial, political, and regulatory factors. These constraints provide opportunities for the architecture that go beyond its traditional role as a guiding tool for technology implementation to a newer role of reorienting institutional relationships. An architecture development approach is proposed that considers regional transportation needs and characteristics so as to increase the benefits from implementing...

Application of Decision Analysis to Intelligent Transportation System Societal Issues. Final Report, 15 March 1996-14 March 1997

Richardson, BC
Albers, WA
Kostyniuk, LP
Barnes, MA
Rodriguez, DA
1997

A demonstration of the use of decision analysis to address societal and institutional issues in an Intelligent Transportation System-based paratransit implementation was performed. A decision analysis technique called Multi-Organization Decision Analysis (MODA) was developed, and it is based on the Decision Risk Analysis process used widely in the private sector. Its objective is to facilitate consensus among the disparate public and private sector stakeholders in a decision process. The stakeholders are represented on a decision-making team, and they are supported by a team of...

Potential Payoffs From Ivhs: A Framework For Analysis Appendix C

Rockwell International Science Center
1992

This Appendix documents the details of the Intelligent Vehicle Highway Systems (IVHS) benefit analysis DEMOS models and provides the PATH user information about what is contained in and how to use the models. The object of this study was to structure an approach to evaluate the relationships of the top-level IVHS goals to the implementable actions and assess the relative benefits of those actions. The DEMOS model has been used as a tool to analyze selected IVHS actions with the goal of determining the key driving parameters through the use of sensitivity analysis.

PLANTiS: Organization And Integration Of Modules

Paramsothy, Thananjeyan
Khattak, Asad
Lovell, David
Kanafani, Adib
1995

This paper discusses the integration of PLANiTS (Planning and Analysis Integration for Intelligent Transportation Systems) components. The integration is achieved by defining a structure for representing transportation improvement actions, performance measures and environment in terms of spatial, temporal and user dimensions. A discussion is also presented on the key issues related to computer implementation including data dimension, a data dictionary, data modeling, and data transformations. A basis is developed for the next implementation of PLANiTS.
