Potential Freeway Capacity Effects of Advanced Vehicle Control Systems
Intelligent Vehicle/Highway Systems (IVHS) are intended to improve the productivity (capacity) and safety of the road transportation system. The PATH program has placed a stronger emphasis...
A Preliminary Systems-Level Evaluation of Automated Urban Freeways
Transportation planners predict that traffic congestion will increase dramatically in the future. With 63% of all congestion on urban freeways, much of it in high-density areas, traditional...
Pavement Image Processing Using Neural Networks
This paper discusses the potential for employing neural network models in the pavement image interpretation and classification stage of an automated pavement condition evaluation system....
Contact-Free IC Cards for New Railway Ticket Systems
Two types of smart cards which can communicate with an automatic gate machine without contact are developed. The first one uses medium wave radio as communication media. The microprocessor...
Experiments with Formal Specifications on MAGGALY
Until lately, safety functions for automatic train driving systems have mostly been implemented with classical techniques such as relays, way circuitry and, more recently, electronic devices....
Safety Microprocessors in Guided Ground Transport
The use of microprocessors performing safety tasks such as Automatic Train Protection systems made more difficult their safety-worthiness assesment. In this paper we will first examine...
Observation and Modeling of Mobile Environment
Perception of the environment in a mobile robot is a difficult task. Other moving objects and various changes in the environment and motion of the robot must be handled together. Control...
Automating Airfield Condition Data Collection
This paper discusses the advantages and disadvantages of the newest technology for the data collection requirements of an airport interested in implementing a pavement management system....

The Role of Sensor Directed, Model-Based Control in Robotic Handling of Nuclear Waste Casks and Materials
This paper discusses the results from several projects at Sandia National Laboratories investigating the application of intelligent machine technologies to remote handling of nuclear waste...
Telerobotic Capabilities for Space Station Operations
Over the past decade, the M.I.T. Space Systems Laboratory has accumulated an extensive data base on space operations typical of those planned for the Space Station, based on integrated...
Space Station Freedom Attached Payloads and Commercialization
The Space Station Freedom (SSF) accommodates a class of payloads called external attached payloads. These payloads are attached to the main truss of Space Station Freedom through the use...
Automated Manufacturing in Platform-Based Orbital Systems (APROPOS)
As an example of an orbital manufacturing scenario, an automated orbital manufacturing system is designed for the production of turbine blades for high pressure turbines. The target here...
Force and Geometry Constraints in Robot Excavation
One interest in this research effort was to develop and test an automatic control approach to adjust machine motions to the force conditions encountered during excavation - essentially...
Application of Automation and Robotics to Lunar Surface Human Exploration Operations
Major results of a study (RLSO, 89) applying automation and robotics to lunar surface base buildup and operations concepts are reported. The study developed a reference base scenario with...
Site Constraints for a Lunar Base
A rigorous site plan is a prerequisite for quantitative analyses of lunar base operations. The development of such a site plan, done for a detailed lunar base study (RLSO, 89), is described...
Lunar Base Elements Designed for Robotic Operations
Equipment concepts developed for a study of robotic lunar surface operations are presented. The concepts were evolved together with a consistent robotic buildup and operations scenario;...
Manifesting for a Lunar Robotic, Oxygen-Producing Base
Using robotic systems and human supervisory control, a lunar base reasonably be established to achieve full production within five years. Intermittent human presence works in coordination...
A Robotic Return to the Moon
An autonomous Lunar precursor mission is proposed as the first step to an effective, low cost return of man to the Lunar surface. The mission would use two self similar robotic vehicles...
A Robotics Testbed for In-Space Assembly Tasks
The operations testbed of the Center for Space Construction at the University of Colorado is described. This testbed serves as a centralized testing environment for interdisciplinary research...
