Intelligent Control Of Vehicles: Preliminary Results On The Application Of Learning Automata Techniques To Automated Highway System, Cem Unsal, John S. Bay, Pushkin Kachroo Nov 1995

Intelligent Control Of Vehicles: Preliminary Results On The Application Of Learning Automata Techniques To Automated Highway System, Cem Unsal, John S. Bay, Pushkin Kachroo

Electrical & Computer Engineering Faculty Research

We suggest an intelligent controller for an automated vehicle to plan its own trajectory based on sensor and communication data received. Our intelligent controller is based on an artificial intelligence technique called learning stochastic automata. The automaton can learn the best possible action to avoid collisions using the data received from on-board sensors. The system has the advantage of being able to work in unmodeled stochastic environments. Simulations for the lateral control of a vehicle using this AI method provides encouraging results.


Flexible Low-Cost Automated Scaled Highway (Flash) Laboratory For Studies On Automated Highway Systems, Pushkin Kachroo, Kaan Ozbay, Robert G. Leonard, Cem Unsal Oct 1995

Flexible Low-Cost Automated Scaled Highway (Flash) Laboratory For Studies On Automated Highway Systems, Pushkin Kachroo, Kaan Ozbay, Robert G. Leonard, Cem Unsal

Electrical & Computer Engineering Faculty Research

This paper addresses the development of a flexible low-cost automated scale highway (FLASH) laboratory which is intended to serve as a catalyst for accelerating the development of many intelligent vehicle highway system (IVHS) concepts. It also highlights the significance of the laboratory for the research, evaluation, and testing of automated highway system (AHS) configurations, architectures, designs and technologies. This laboratory, using small scale standardized vehicles will serve as a test bed for the economical development and evaluation of various hardware, software, and management systems before full scale testing and deployment. The laboratory will provide the capability to test day and …


Least-Cost Transportation Planning In Odot: Feasability Report, Anthony M. Rufolo, Lois M. Bronfman, James G. Strathman Mar 1995

Least-Cost Transportation Planning In Odot: Feasability Report, Anthony M. Rufolo, Lois M. Bronfman, James G. Strathman

Center for Urban Studies Publications and Reports

Least Cost Planning or Integrated Resource Planning is used in the electric utility industry to broaden the scope of choices to meet service requirements. This typically includes methods to reduce the demand for electricity as well as the more traditional electric generation options. Techniques have been developed to compare the cost of electricity generation with the cost of meeting service requirements by reducing electricity usage. In addition to cost considerations, utilities typically take account of uncertainty associated with forecasts and a variety of other considerations in specifying their least cost plan.


In R.I. Bad Driving Is A Way Of Life, Chester Smolski Jan 1995

In R.I. Bad Driving Is A Way Of Life, Chester Smolski

Smolski Texts

"A transplanted Rhode Islander, now living in Portland, Oregon tells an amusing story about Rhode Island drivers. Having lived in Oregon's major city for two years and driving there every day, she became accustomed to the good driving habits of the residents of that city and its suburbs, containing a population about 50 percent greater than that of the Providence metropolitan area. She claims that in those two years of driving she was never once frightened by someone cutting into the traffic lane in which she was driving, until recently. And then it happened, the car to her left cut …
