Right-hook crash causality at signalized intersections

Creator:: Jannat, Mafruhatul
Abstract:: A Right-hook (RH) crash is a common type of bicycle-motor vehicle crash that occurs between a right-turning vehicle and through-moving bicycle at an intersection. At signalized intersections, RH crashes can occur at the onset of the green or during the latter portion of the green phase. In spite of the...

Unobserved Heterogeneity and Spatial Correlation: Statistical and Econometric Analyses of Heavy-Vehicle Hard Braking and Crash Frequency by Crash Type

Creator:: Anderson, Jason C.
Abstract:: This dissertation provides a comparison of statistical and econometric frameworks, using a previously unused freight data source, to study crash frequency by crash type and heavy-vehicle hard braking in Oregon. Hard braking can serve as a proxy for several factors, one of which is safety. Therefore, with the hard braking...

Spatial and Temporal Effects of Large Truck-Involved Crash Injury Severities : A Mixed Logit Analysis

Creator:: Pahukula, Jasmine
Abstract:: Large truck-involved crashes have a significant impact on both the economy and society. They are associated with high injury severities, high crash costs and contribute to congestion in urban areas. Past studies have investigated the contributing factors of large truck-involved crashes, however a study isolating the spatial and temporal effects...

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...

An Evaluation of the Random-Parameter and Latent Class Methods for Heavy Vehicle Injury Severity and Crash Rate Analysis : An Idaho Case Study by Roadway Classification

Creator:: Anderson, Jason
Abstract:: This thesis provides a comparison of advanced econometric frameworks to account for unobserved factors in crash reported data (also referred to as unobserved heterogeneity) while identifying contributing factors by roadway classification for heavy vehicle injury severity and crash rates. The presented thesis provides two manuscripts that expand the literature regarding...

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...

Roundabout Safety: Econometric and Machine Learning Models and Applications

Creator:: Zubaidi, Hamsa AN
Abstract:: The rapid growth in the number of roundabouts raises some significant research challenges, especially around safety performance and evaluation in the U.S. Despite the safety advantages that roundabout geometric design brings, crashes still occur. While operationally roundabouts are good at preventing severe crashes, they may lead to more less severe...

Using the predictive method in the 2010 Highway Safety Manual to identify hazardous intersections in Corvallis, OR

Creator:: Zhou, Yanfen
Abstract:: An intersection, due to its vehicle and pedestrian conflict movements, experiences complex traffic situations that might contribute to crashes. In the city of Corvallis, OR, historically more than 80% of the total crashes have occurred within an intersection or have been designated as intersection-related. It is important to develop a...

Developing safety performance functions for 4-leg single-lane roundabouts based on Oregon data : a case study

Creator:: Zheng, Jianfei
Abstract:: Roundabouts have become an alternative for traditional intersections due to the safer operational performance. Previous research has provided crash modification factors (CMFs) as a criterion based on before-after studies as to evaluate the safety performance of roundabouts. One drawback of assessment based on crash modification factors, however, is that a...

Crowdsourcing Data-driven Development of Bicycle Safety Performance Functions (SPFs) : Microscopic and Macroscopic Scales

Creator:: Chen, Chen
Abstract:: While riding bicycles has been promoted for its health, economic, and environmental benefits, it also complements other modes to complete a safe, efficient, and reliable transportation system. However, the dramatic increase of bicycle usage in the U.S. is accompanied by a growth of bicycle crashes. The U.S. Department of Transportation,...
