Evaluation of alternative information signs in Oregon

Creator:: Neill, Justin Michael
Abstract:: The number of international inbound tourists to the United States has risen steadily. To serve these and other tourists best, traffic signs need to communicate information correctly across a potential language barrier. Of particular interest is the traffic sign intended to communicate directions to Tourist Information centers. While the general...

Evaluating Driver Response to the Onset of Circular Yellow Indication in the Presence of a Following Vehicle at Isolated High-Speed Signalized Intersections

Creator:: Mohammed, Hameed A.
Abstract:: Dilemma zones on the approach to high-speed signalized intersections have been identified as a safety problem that can contribute to rear–end and right–angle crashes. However, in situations when a pair of vehicles is caught in the dilemma zone, it is not well understood how the following vehicle’s headway and classification...

Implications of Red Signal Countdown Timers on Visual Attention of Oregon Drivers

Creator:: Wyman, Amy A.
Abstract:: Red Signal Countdown Timers (RSCTs) are devices placed at intersections to inform drivers of the time remaining on a red indication before it turns green, typically to improve intersection efficiency. This study examines the visual attention of Oregon drivers to circular red (CR) indications with RSCTs as compared to standard...

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...

Safety and efficiency benefits of traffic signal countdown timers : a driving simulator study

Creator:: Islam, Mohammad Rabiul
Abstract:: Traffic signal countdown timers (TSCT) are innovative, practical and cost effective technologies with the potential to improve efficiency and safety at signalized intersections. The purpose of these devices is to assist motorists in decision making at signalized intersections with real time signal change information. While successful implementation of these devices...

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...

The Evaluation of Engineering Treatments for Right-Hook Crashes at Signalized Intersections with Bicycle Traffic

Creator:: Warner, Jennifer Lynn
Abstract:: A right-hook crash is a bicycle-motor vehicle crash between a right-turning motor vehicle and an adjacent through-moving bicycle. This study focuses on right-hook crashes that occur during the latter stage of the circular green indication at signalized intersections with shared right-turn and through lanes. The overall objective was to evaluate...

Impact of Bicycle Rolling Stop Laws on Safety-Relevant Behaviors in the Pacific Northwest

Creator:: Woodside, Jasmin Barnes
Abstract:: Previous research has found some bicyclists disregard circular red indications and stop signs. Possible justifications include a desire to increase safety, save energy, save time, and increase visibility. Because of this, many bicyclists feel as though stopping at stop signs, especially in the absence of conflicting vehicular traffic, is an...

Evaluation of Cycling Behavior: Factors that Influence Bicyclists’ Comprehension, Comfort, and Stress

Creator:: Cobb, Douglas P.
Abstract:: Travel demand has increased due to population growth, increase of vehicle ownership, and development patterns resulting in greater levels of congestion, pollution, and crash frequency. One approach to demand management is to increase the share of trips made by bicycles. With the increase in bicycling rates, there is a critical...

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...
