Simulation Study Of Learning Automata Games In Automated Highway Systems, Cem Unsal, Pushkin Kachroo, John S. Bay

Electrical & Computer Engineering Faculty Research

One of the most important issues in Automated Highway System (AHS) deployment is intelligent vehicle control. While the technology to safely maneuver vehicles exists, the problem of making intelligent decisions to improve a single vehicle’s travel time and safety while optimizing the overall traffic flow is still a stumbling block. We propose an artificial intelligence technique called stochastic learning automata to design an intelligent vehicle path controller. Using the information obtained by on-board sensors and local communication modules, two automata are capable of learning the best possible (lateral and longitudinal) actions to avoid collisions. This learning method is capable of …

Sliding Mode For User Equilibrium Dynamic Traffic Routing Control, Pushkin Kachroo, Kaan Ozbay

Electrical & Computer Engineering Faculty Research

Presents a solution to the user equilibrium dynamic traffic routing (DTR) problem for a point diversion case using feedback control methodology. The sliding mode control technique which is a robust control methodology applicable to nonlinear systems in canonical form is employed to solve the user equilibrium DTR problem. The canonical form for this problem is obtained by using a feedback linearization technique, and the uncertainties of the system are countered by using the sliding mode principle. Simulation results show promising results.

Issues In The Design Of A Stop-Level Transit Patronage Model, James G. Strathman, Kenneth Dueker, Zhongren Peng

Center for Urban Studies Publications and Reports

Tri-Met, the transit agency serving the Portland, Oregon metropolitan area is implementing a new bus dispatching system (BDS) that includes automated vehicle location (AVL) technology. An important objective in the agency's decision to invest in a new dispatching system was to maintain or improve service reliability in an urban environment characterized by rapid growth and worsening traffic congestion.

Measuring The Impact Of Light Rail Systems On Single Family Home Values: A Hedonic Approach With Gis Application, Hong Chen, Anthony M. Rufolo, Kenneth Dueker

Center for Urban Studies Publications and Reports

In theory, proximity to a light rail (LRT) may have two different effects on residential property values. On the one hand, accessibility (proximity to the LRT stations) may increase property values. On the other hand, nuisance effects (proximity to the LRT line and stations) may decrease property values. Existing empirical studies are inconclusive, and failure to separate the effects of accessibility from the nuisance effects may explain some of the ambiguity. This paper examines the impact of the light-rail system (MAX) in Portland, Oregon, on single-family home values using distance to rail stations as a proxy for accessibility and distance …

Oregon Dot Slow-Speed Weigh-In-Motion (Swim) Project: Analysis Of Initial Weight Data, Tim Swope, James G. Strathman

Center for Urban Studies Publications and Reports

This report presents the results of a preliminary analysis of axle weights from the Oregon DOT Slow-Speed Weigh in Motion (SWIM) scale at the Wyeth weigh station.* This report includes an analysis of methodology and variables used in the study; estimates of accuracy and precision of the WIM readings; and a regression analysis of the WIM and static scale weighings. Axles weights were collected from the traffic stream.

Exploring And Visualizing The Census Transportation Planning Package (Ctpp) Urban And Statewide Elements, Thomas J. Kimpel, Kenneth Dueker, Philip J. Wuest, David R. Brooks

Center for Urban Studies Publications and Reports

The purpose of this report is to document the types of transportation analyses that can be undertaken with the Census Transportation Planning Package (CTPP). In particular, this report focuses on exploring and visualizing the various elements of the CTPP data set. It is structured as a series of small-scale studies that have incorporated the use of CTPP data in order to generate information on a number of transportation-related topics. A general overview of each study is given, along with a description of the CTPP data used in the analysis, and a brief interpretation of the results. It is hoped that …

Feedback Control Solutions To Network Level User-Equilibrium Real-Time Dynamic Traffic Assignment Problems, Pushkin Kachroo, Kaan Ozbay

Electrical & Computer Engineering Faculty Research

A new method for performing dynamic traffic assignment (DTA) is presented which is applicable in real time, since the solution is based on feedback control. This method employs the design of nonlinear H∞ feedback control systems which is robust to certain class of uncertainties in the system. The solution aims at achieving user equilibrium on alternate routes in a network setting.
