transportation research. The United States Department of Transportation (USDOT) annually invests approximately $180 million in State Planning and Research (SPR) and University Transportation Centers (UTC). This investment generates an extensive portfolio of “grey literature” that is not yet uniformly cataloged or accessible, despite the best efforts of the National Technical Information Service, the Transportation Research Board, and the National Transportation Library. This paper reports on a review of publishing and archiving practices for transportation research technical reports, summarizes best practices, and recommends that UTC and SPR research programs seek and strengthen partnerships with libraries to facilitate improved production, stewardship and …


Velocity Contour Weighting Method. Ii: Evaluation In Trapezoidal Channels And Roughness Sensitivity, Daniel Howes, Brett F. Sanders Nov 2011

Velocity Contour Weighting Method. Ii: Evaluation In Trapezoidal Channels And Roughness Sensitivity, Daniel Howes, Brett F. Sanders

BioResource and Agricultural Engineering

The Velocity Contour Weighting Method (VCWM) was developed in Part I to accurately estimate the cross-sectional average velocity of a prismatic channel flow using acoustic Doppler velocity meter (ADVM) measurements of centerline velocity. Here, the VCWM is validated by its successful application to 25 different concrete-lined trapezoidal channels used for irrigation water delivery. At each site, the cross-sectional distribution of velocity is measured by an acoustic Doppler velocimeter (ADV), which is moved horizontally and vertically through a sampling grid. Multiple tests at some sites led to a total of 51 sets of cross-sectional measurements. ADVM measurements are simulated by interpolating …


Velocity Contour Weighting Method. I: Algorithm Development And Laboratory Testing, Daniel J. Howes, Brett F. Sanders Nov 2011

Velocity Contour Weighting Method. I: Algorithm Development And Laboratory Testing, Daniel J. Howes, Brett F. Sanders

BioResource and Agricultural Engineering

An algorithm is developed for real-time estimation of the cross-sectional average velocity of a channel flow by using an upward-looking pulsed wave acoustic Doppler velocity meters (ADVM). The Velocity Contour Weighting Method (VCWM) is applicable to gradually varied flows in prismatic channels and requires little to no calibration. VCWM estimates the average velocity as a weighted average of ADVM bin velocities. Weights are based on the velocity distribution sampled by the ADVM. Collectively, the VCWM is able to adapt to a wide range of channel geometry and roughness features. Expressions for the velocity weights are developed by first applying a …

This study investigated potential impacts of climate change on travel disruption resulting from road closures in two urban watersheds in the Portland metropolitan area. We used ensemble climate change scenarios, a hydrologic model, stream channel survey, a hydraulic model, and a travel forecast model to develop an integrated impact assessment method. High-resolution climate change scenarios are based on the combinations of two emission scenarios and eight general circulation models. The Precipitation-Runoff Modeling System was calibrated and validated for the period 1988-2006, and simulated for determining the probability of floods from 2020-2049. We surveyed stream cross sections at five road crossings …


A Pomdp Model For Guiding Taxi Cruising In A Congested Urban City, Lucas Agussurja, Hoong Chuin Lau Nov 2011

A Pomdp Model For Guiding Taxi Cruising In A Congested Urban City, Lucas Agussurja, Hoong Chuin Lau

Research Collection School Of Computing and Information Systems

We consider a partially observable Markov decision process (POMDP) model for improving a taxi agent cruising decision in a congested urban city. Using real-world data provided by a large taxi company in Singapore as a guide, we derive the state transition function of the POMDP. Specifically, we model the cruising behavior of the drivers as continuous-time Markov chains. We then apply dynamic programming algorithm for finding the optimal policy of the driver agent. Using a simulation, we show that this policy is significantly better than a greedy policy in congested road network.

Bridge Damage Models For Seismic Risk Assessment Of Oregon Highway Network, Peter Dusicka, Jeffery Roberts Oct 2011

Bridge Damage Models For Seismic Risk Assessment Of Oregon Highway Network, Peter Dusicka, Jeffery Roberts

TREC Final Reports

The highway transportation network of the United States relies on the health and integrity of major infrastructure elements such as bridges. Frequently traveled parts of Oregon are within the seismically active Pacific Northwest and many of the bridges were designed and built to lateral demands that were assumed to be less than the current expectation, a deficiency caused by our growing awareness of seismic hazard and our enhanced understanding of the non-linear response of bridges. This vulnerability to damage from earthquakes can result in not only immediate damage, but also in potentially lingering economic impact caused by the disruption to …


Maintaining Safe, Efficient And Sustainable Intermodal Transport Through The Port Of Portland, David A. Jay, Jiayi Pan Oct 2011

Maintaining Safe, Efficient And Sustainable Intermodal Transport Through The Port Of Portland, David A. Jay, Jiayi Pan

Civil and Environmental Engineering Faculty Publications and Presentations

About $15 billion of freight passes annually through the Lower Columbia River (LCR) navigation channel to reach Portland and Vancouver, where most of it connects with land transport. This commerce plays a vital role in sustaining the regional economy and connecting Oregon to the global economy. The timely connection of truck and rail transport with vessels is vital, especially for export traffic. This link is susceptible to disruption if water depths in the navigation channel are shallower than expected, leading to delays and/or draft limitations. Moreover, ship drafts have increased in recent decades, 25% of the vessels calling in the …


Analysis Of Migration Models Of Biogeography-Based Optimization Using Markov Theory, Haiping Ma, Daniel J. Simon Sep 2011

Analysis Of Migration Models Of Biogeography-Based Optimization Using Markov Theory, Haiping Ma, Daniel J. Simon

Electrical and Computer Engineering Faculty Publications

Biogeography-based optimization (BBO) is a new evolutionary algorithm inspired by biogeography, which involves the study of the migration of biological species between habitats. Previous work has shown that various migration models of BBO result in significant changes in performance. Sinusoidal migration models have been shown to provide the best performance so far. Motivated by biogeography theory and previous results, in this paper a generalized sinusoidal migration model curve is proposed. A previously derived BBO Markov model is used to analyze the effect of migration models on optimization performance, and new theoretical results which are confirmed with simulation results are obtained. …

Toward GemeinschaftsgefüHl: Exploring Subordinate And Manager Perceptions Of Trust And Perceptions Regarding Behavioral Change Potential, Bobby G. Martin

Publications

In this qualitative, phenomenological study, Maslow‘s Eupsychian theory was used as the guiding framework for exploring the perceptions of trust and the behavioral change potential of subordinates (includes frontline supervisors) and managers (excludes frontline supervisors) within selected aviation maintenance organizations in Arizona. The problem addressed in the study was the growing concern that managers willfully mistreated subordinates, which led to decreased trust, motivation, and productivity. A combined representative sample of 10 maintenance technicians and frontline supervisors was purposively selected from the production lines of a large commercial aviation repair and overhaul station located in Arizona. An additional combined representative sample …


Evaluation Of Safe Routes To School Programs: Qualitative And Quantitative Analysis Of Parental Decision-Making, Lynn Weigand, Noreen Mcdonald Aug 2011

Evaluation Of Safe Routes To School Programs: Qualitative And Quantitative Analysis Of Parental Decision-Making, Lynn Weigand, Noreen Mcdonald

TREC Final Reports

In the United States, walking to school declined from 42% of 5-18 year olds in 1969 to 16% in 20011. The US Department of Transportation has responded to this dramatic decrease by funding the Safe Routes to School program for $612 million in SAFETEA-LU. The program’s funding emphasize infrastructure improvements such as completing sidewalks and adding crosswalks by requiring between 70% and 90% of funding be allocated toward infrastructure. However, recent research shows that 2 of 3 children who currently are driven to school, but live close enough to walk, do so because it is more convenient for parents. Currently, …


Stereoscopic Vision's Impact On Spatial Ability Testing, George Takahashi Jul 2011

Stereoscopic Vision's Impact On Spatial Ability Testing, George Takahashi

Purdue Polytechnic Masters Theses

A look into spatial ability testing tools and the variations that past researchers made to focus on key factors that affect test scores, will demonstrate the need for tuning traditional testing methods to accommodate a wider demographic and provide more accurate results. Due to technological limitations of the time, a large variety of past spatial tests were developed by hand-drawings. Within this research, the addition of stereoscopic vision is analyzed to determine the value of said changes on human perception of spatial entities.

A Simplified Method For Analyzing Factors Contributing To Motorcyclists’ Fatal Injuries In Ohio, Deogratias Eustace, Vamsi Krishna Indupuru

Civil and Environmental Engineering and Engineering Mechanics Faculty Publications

The aim of this paper was to analyze traffic crash data by using a simplified method in determining significant factors that increase the risk of a motorcyclist being fatally injured once involved in a motorcycle crash in Ohio. The concept of overrepresentation, which is similar to relative risk, was used in identifying significant variables associated with the elevated risk of a motorcycle crash resulting into a fatality. The overrepresentation factor (ORF) was calculated for each variable of interest. The ORF offers a simple but powerful procedure of determining whether a certain factor significantly occurs more or less frequently in one …

Navigating the Future of the Colorado River (Martz Summer Conference, June 8-10)

Competition for scarce Colorado River water resources is nothing new, but the conflicts that prompted the seven basin states to negotiate the 1922 Colorado River Compact have grown considerably fiercer and more complex in recent decades. In 2007, responding to the challenges of increasing demand and sustained drought, the seven basin states and a number of other affected interests agreed to a set of interim guidelines for allocating Colorado River water in the event of shortages. This agreement represents an important evolution in the governance of the Colorado River, suggesting that the many interests in the basin can work together …
