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
Full Text:: employs driving simulation as a means to collect driver response data at the onset of the CY

The Number of Lanes and Crash Injury Severities of Commercial Motor Vehicle Drivers: Advanced Econometric Models and Applications

Creator:: Kim, Jaekook
Abstract:: Considering the deadly impacts of commercial motor vehicle (CMV) crashes on road safety, many previous studies have put in efforts to find the determinants of CMV crash injury severities. However, studies examining the impact of the different number of lanes on CMV crash injury severities are lacking. Besides, the importance...
Resource Type:: Masters Thesis
Full Text:: instability (unstable effects of variables over time) have been increasingly emphasized in crash data

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...
Resource Type:: Masters Thesis
Full Text:: . Eye movement data were used to examine participants’ visual attention on the removed pavement

Developing an analysis framework to compare commuter rail service and bus service in the Mid-Willamette Valley in Oregon

Creator:: Roholt, Ian M.
Abstract:: This thesis develops a framework for analyzing the application of commuter rail and bus services between several small urban centers to enhance overall connectivity. The study includes analyzing specific performance criteria for commuter rail service and express bus service based on data from existing systems around the U.S. The study...

Implications of distracted driving on driver behavior in the standing queue of dual left-turn lanes : an empirical study

Creator:: Marnell, Patrick Stanley
Abstract:: Driver distraction is a commonly observable phenomenon with a significant effect on the transportation network. Although the negative effects of driver distraction on safety are commonly studied, there has been little effort made to investigate the impacts of distraction on efficiency. This study will examine driver behavior in standing queues...
Resource Type:: Masters Thesis
Full Text:: independent variables have on the headways of the first five vehicles. Examining an empirical data set of

Pedestrian distraction : pedestrian behaviors at midblock crossings considering geometric and environmental conditions

Creator:: Kautz, Julia Anne
Abstract:: Pedestrian distraction at roadway crossings has been correlated with a higher risk of pedestrian-vehicle collisions due to the pedestrian's cognitive, visual, and motor attention being drawn to a wide variety of secondary tasks. This study is different from previous field studies of pedestrian midblock crossings in that the geometric layout...
Resource Type:: Masters Thesis
Full Text:: Eugene, Oregon. A combination of digital video and researcher field notes were used to obtain the data

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...
Resource Type:: Masters Thesis
Full Text:: choices about when and where to park is scarce, and data from those available studies usually comes from

Investigation of effectiveness of radar speed signs and additional lighting for speed control in highway construction and maintenance work zones

Creator:: Jafarnejad, Ali
Abstract:: Every year thousands of people are killed or injured in work zone crashes in the US due to excessive speed, distraction, inattentiveness, low visibility, and other factors. Roadway construction and maintenance operations often occur at night when the traffic volume is low, creating less congestion and delay to the traffic....
Resource Type:: Masters Thesis
Full Text:: other vehicle and lighting data were collected on different nights when the lighting equipment was

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...
Resource Type:: Masters Thesis
Full Text:: data were used to examine participants’ visual attention on the traffic signals, crosswalk placement
