  • Effectiveness of curve advisory speed signs : a characterization of road operations in western Oregon

    Creator:
    Avelar Morán, Raúl Eduardo
    Abstract:
    Posting advisory speed signs at sharp horizontal curve locations is a common practice in the U.S. These signs recommend drivers safe speeds to negotiate such curves. Literature indicates that adherence to advisory speeds is, in general, poor. Moreover, limited research is available that quantifies safety implications of these signs. This...

  • Safety performance of curve advisory speed signs

    Creator:
    Avelar Moran, Raúl Eduardo
    Abstract:
    Posting advisory speed signs at sharp horizontal curve sites is a practice well established in the United States. The purpose of these signs is to provide the driving public with a safe speed to negotiate such curves; however, the link between these signs and safety has not yet been clearly...

  • Optimal sensor placement for measuring operating speeds through curves on rural two-lane highways

    Creator:
    Mecham, Megan E.
    Abstract:
    Operating speed is one of the best performance measures that can tell transportation agencies how well or how poorly the transportation system is functioning. Fluctuating operating speeds often mean there is a design flaw or something about the physical road design that violates drivers' expectations. A primary example of this...

  • A validation of the Oregon State University driving simulator

    Creator:
    Brown, Lacy S.
    Abstract:
    Driving simulation is widely accepted as a safe, effective, and economical alternative for investigating driver behavior in a variety of contexts. However, in order to apply simulator-based research results to real-world settings, the performance measures acquired through simulated driving experiments must first be validated. This research was aimed at validating...

  • Normal acceleration characteristics of the leading vehicle in a queue at signalized intersections on arterial streets

    Creator:
    Zhu, Hong
    Abstract:
    Normal acceleration characteristics of passenger cars provide valuable information for various aspects of transportation engineering, including use in the geometric designs of intersections, freeway ramps, passing lanes, acceleration lanes, turning bays, or in the development of traffic simulation or fuel consumption models. However, the data used in previous studies are...

  • 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...

    Creator:
    Rogge, Angela Anne
    Abstract:
    The educational environment is filled with different types of students, all with diverse learning styles. The Meyers-Briggs Type Indicator and Kolb’s Theory of Experiential Learning are generally accepted methods for determining and assessing a person’s preferred method of information processing. There has been research that suggests learning styles are specific...

  • The evolution of practical safety audits in the United States

    Creator:
    Houghton, Tegan Marie
    Abstract:
    This thesis evaluates pre-construction auditing procedures used in the United Kingdom, Australia, and New Zealand in order to help create post-construction auditing procedures for the state of Oregon. It was funded as part of the development of the Oregon Department of Transportation (ODOT) Safety Investigation Manual, and also evaluates content...

  • Road user understanding of shared lane pavement markings (sharrows) case study - Corvallis, OR

    Creator:
    Cosma, Ioana
    Abstract:
    This thesis focuses on shared use lane facilities and road user understanding. Shared use lanes (sharrows) are a common solution for road facilities that are too narrow to accommodate a full bicycle lane and where the local jurisdiction wants to reduce dooring crashes. In recent years, engineers have focused on...

  • 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...
