Consideration of Driver Behavior in the Design of Red Light Extension Systems

Creator:: McCrea, Sarah Anne
Abstract:: Red Light Running (RLR) is a safety hazard at signalized intersections in Oregon and throughout the United States. Various methods of mitigating factors contributing to RLR have been implemented but few protect against a conflict when a vehicles runs a red light. Additionally, current prediction algorithms are complicated; there is...

Evaluation of a Pedestrian Call Extension and Cancelation System at a Midblock Trail Crossing

Creator:: Milacek, McKenna
Abstract:: Signalized intersections often provide pushbuttons to call for pedestrian service to minimize conflicting movements between road users. Signalized midblock crossings typically increase safety for pedestrians in locations with high traffic volumes and multiple lanes in each direction. However, unnecessary vehicular delay occurs from “ghost” pedestrian intervals when someone activates the...

Effect of an Idealized Mangrove Forest of Moderate Cross-shore Width on Loads Measured on a Sheltered Structure and Comparison with Predicted Forces

Creator:: Mitchell, William T.
Abstract:: As coastal communities face increasing chronic and acute hazards, nature-based coastal engineering solutions have experienced a rapid growth in popularity and interest. Recent works on this topic have shown that “Green Infrastructure” may be effective at mitigating coastal hazards and therefore provide sustainable adaptation alternatives to traditional engineering solutions such...

Bearing capacity and immediate settlement of shallow foundations on clay

Creator:: Strahler, Andrew W.
Abstract:: Shallow foundations are extensively used to support structures of all sizes and derive their support from near surface soils. Thus, they are typically embedded up to a few meters into the soil profile. Designers of shallow foundations are required to meet two limit states: overall failure of the soil beneath...

Stochastic analysis of the nonlinear response transition behavior of an ocean system

Creator:: Yuk, Dongjun
Abstract:: The nonlinear response of an ocean system subjected to random excitations can exhibit very complex dynamic behaviors including jump phenomena and coexistence of attractors. In this study, the stochastic system response behavior of a simple (Duffing) oscillator under narrow-band random excitations is first examined in the subharmonic resonance region. A...

Application of the generalized Melnikov method to weakly damped parametrically excited cross waves with surface tension

Creator:: Fadel, Suzan M.
Abstract:: The Wiggins-Holmes extension of the generalized Melnikov method (GMM) is applied to weakly damped parametrically excited cross waves with surface tension in a long rectangular wave channel in order to determine if these cross waves are chaotic. The Lagrangian density function for surface waves with surface tension is simplified by...

Three-dimensional experiments and modeling of anisotropic clay

Creator:: Anantanasakul, Pongpipat
Abstract:: This dissertation presents the results of a research effort conducted to better understand the stress-strain, volume change, shear band formation, and strength characteristics of normally consolidated anisotropic clay under fully three-dimensional stress states. A series of consolidated drained true triaxial tests with a constant mean effective stress and constant Lode...

BOD and toxicity of log leachates

Creator:: Atkinson, Sheridan William
Abstract:: A series of log storage experiments were conducted to determine whether leachates derived from water storage of logs are acutely toxic to fish. Log segments approximately 18 inches long and 16 inches in diameter were stored in tanks and held submerged for a period of 7 days. The holding water...

The effect of pulverization on a lime stabilized clay soil

Creator:: Dito, Edward Leonard
Abstract:: The objectives of this investigation were to determine the effect of pulverization on the strength, durability and swell characteristics of a lime stabilized clay soil. Samples were prepared with three different gradations which represented the pulverization of the soil. Maximum clay lump sizes of 3/4", 1/2" and passing #4 sieve...
