  • Reducing Centerline Rumble Strips Effects on Pavement Performance

    Creator:
    Weaver, Joshua D.
    Abstract:
    Centerline rumble strips (CLRS) have proven to be a cost-effective safety measure in reducing lane departure crashes. However, there are often unintended consequences associated with the installation of CLRS, particularly in rural mountainous areas or snow zones. These consequences include the accumulation of water and ice on the roadway and...

  • Enhancing Technology Integration in the Construction Industry : A Focus on Safety Technologies

    Creator:
    Nnaji, Chukwuma A.
    Abstract:
    Recent statistics suggest that the construction industry continues to experience poor project performance. Specifically, construction productivity has witnessed a meager annual growth of 1% over the past 20 years while the industry constantly records both a high number of fatalities and a high fatality rates relative to other industries. The...

  • Best Practices for Work Zone Safety during Traffic Control Placement, Removal, and Modification

    Creator:
    Moeung, Serey Raksa
    Abstract:
    Previous research has shown that traveling in a work zone involves a higher risk of crashing compared to normal (non-work zone) driving conditions. Research further suggests that the severity of work zone crashes is greater on average than non-work zone crashes. The period of time in which the traffic control...

  • 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....

  • Evaluating safety at Oregon‘s isolated, high-speed, signalized intersections

    Creator:
    Kopper, Neil H.
    Abstract:
    Isolated approaches at signalized intersections with posted speed limits of 45 mph or greater generally experience large numbers of rear-end and angle collisions. A combination of less attentive drivers, high operating speeds, and less than ideal intersection characteristics can result in crash frequencies well above expected rates. A number of...

  • Group Rapport and Nonverbal Expressivity

    Creator:
    Fultz, Amber A.
    Abstract:
    The purpose of this thesis was to assess the relationship between group rapport and nonverbal expressivity using three data sources: self-report, observer ratings, and test data. Assessing these constructs using multiple data sources enabled the construction of multitrait-multimethod matrices. These matrices allowed for a critical evaluation of the convergent and...

  • An Empirical Study of Work-zone Safety and Mobility Using Surveys and Anonymous User Generated Trip Information

    Creator:
    Fiawoyife, Kenneth K.
    Abstract:
    The two primary considerations for highway work-zones are its effect on commuter mobility and worker safety which are often spoken of together. However, it must be noted that they often conflict with each other. For example, traffic control plans that reduce travel speed in work-zones improve both commuter and worker...

  • Perceived Effectiveness of Highway Work Zone Intrusion Mitigation Technologies: A State DOT Perspective

    Creator:
    Kadalli, Manjunath Veeresh
    Abstract:
    Highway work zones are extremely dangerous environments due to the presence of workers near high-speed traveling vehicles. This dynamic environment results in a disproportionate number of accidents that cause injury and casualty to both drivers and workers due primarily to vehicular intrusions into work zones. Several emerging work zone intrusion...

  • Northern goshawk breeding habitat selection within high-elevation forests of southwestern Colorado

    Creator:
    Ferland, Cheron L.
    Abstract:
    The northern goshawk (Accipiter gentilis) is a species of concern in the western United States due to its association with mature structural stage forests. I employed a use-versus-availability study design to quantify the vegetative, physiographic, and landscape variables associated with goshawk breeding habitat selection in the San Juan Mountains of...
