Integrating Driving Simulator Experiment Data with Multi-Agent Connected Automated Vehicle Simulation (Ma-Cavs) Platform to Quantify Improved Capacity

Creator:: Chand, Cadell Y.
Abstract:: Autonomous vehicles (AVs) at varying market penetrations will change traffic flow and highway performance. At AV market penetrations between 0% and 100%, human driven vehicles (HVs) will be interacting with AVs. However, little is known about how HVs interact with AVs. This study attempts to quantify HV headways when following...

Innovative Applications of Real-World Vehicle Trajectories Collected with a Radar Vehicle Detection System

Creator:: Simpson, Ellen J.
Abstract:: Left turn movements are considered to be the highest risk movements through an intersection, and can result in head on, angle, or side impact crashes. The flashing yellow arrow (FYA) for use as a permissive left turn phasing indication is relatively recent, first appearing in the 2009 edition Manual on...

Fuzzy logic for improved dilemma zone identification : a simulator study

Creator:: Moore, Derek
Abstract:: The Type-II dilemma zone refers to the segment of roadway approaching an intersection where drivers have difficulty deciding to stop or proceed through at the onset of the circular yellow (CY) indication. Signalized intersection safety can be improved when the dilemma zone is correctly identified and steps are taken to...
Resource Type:: Masters Thesis

A safety evaluation of turn lane-adjacent bike lane configurations in Portland, Oregon

Creator:: Wyman, Amy
Abstract:: The Manual on Uniform Traffic Control Devices prohibits positioning a bike lane right-adjacent to a vehicle turn-only lane to mitigate the potential for right-hook crashes. However, it provides no specific guidance on positioning with respect to bus-only lanes. This thesis describes a before/after safety evaluation of bike lanes positioned left...

Evaluation of Driver Behavior during Right Turn Maneuvers at Signalized Intersections: Mitigation of Driver-Pedestrian Conflicts with a Right Turn Flashing Yellow Arrow

Creator:: Jashami, Hisham
Abstract:: Accommodating motor vehicles that are turning (left or right) at signalized intersections requires a careful understanding of the safety and efficiency of design and operational variables. Turning vehicles are the primary collision risk for non-motorized road users at signalized intersections. When turning movements need to be controlled, proper driver response...

Removing Residual Lane Markings to Reduce Driver Confusion

Creator:: Weber, Jane B.
Abstract:: When pavement markings on roadways are removed, scarring can occur leaving behind traces of where the marking used to be called ghost lines. These ghost lines can confuse drivers on the roadway and divert their attention from the correct lane markings leading them into the false lane. Previous research has...

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...

Visual Search Patterns and Behavior of Left Turning Bicyclists at Roadway Intersections: A Field Study

Creator:: Burns, Patrick O.
Abstract:: This research effort considers bicyclist’s left-turn behavior at roadway intersections with varying levels of traffic control; specifically, seeking to address the question where do bicyclists look to acquire information. A demographic comparison was made to determine if factors such as gender or experience influence the nature of how a bicyclist...

Preliminary Assessment of Driver Parking Decisions From A Heavy Vehicle Driving Simulator To Inform Curb Management Decisions

Creator:: Liu, Yujun
Abstract:: As e-commerce and urban deliveries spike, there is an increasing demand for curbside loading/unloading space. However, commercial vehicle drivers face numerous challenges while navigating dense urban road networks. Previous literature on the topic of how commercial vehicle drivers make choices about when and where to park is scarce, and data...

Evaluation of Setback Crosswalk to Mitigate Vehicle-Pedestrian Conflicts at Intersections

Creator:: Chai, Eileen Pei Ying
Abstract:: It is considered best practice when designing pedestrian access at intersections to provide two curb ramps at each street corner. In Oregon, there are many locations where long ramp runs cause curb ramps to be set back a significant distance from the apex of the intersection corner to meet this...
