  • Development of a priority rating system for highway safety improvements

    Creator:
    Iranitalab, Farhad
    Abstract:
    This thesis presents the procedure adopted to develop the priority rating system for highway safety improvements. Safety hazards are classified into four categories: (1) Railroad crossings, (2) Intersections, (3) Geometric-Related Hazards, and (4) Roadside Hazards. For each category of hazards, relationships are developed to obtain a hazard index and expected...

  • A procedure to identify and evaluate forest arterial and collector road networks

    Creator:
    Kehr, Richard H.
    Abstract:
    This thesis presents a procedure to identify and evaluate forest arterial and collector networks. The procedure identifies those decision criteria important in evaluating both the arterial and collector networks and the specific facilities identified on these networks. The procedure incorporates the decision criteria and results from network and facility analysis...

  • The evaluation and selection of highway safety improvements for local jurisdictions

    Creator:
    Haq, Asif Jinnah
    Abstract:
    Many hazardous locations exist on our local and street highway systems. Such hazards contribute to the frequency and severity of traffic accidents. The elimination and mitigation of the hazards reduces accident frequency and severity, as measured by the number of fatalities, injuries and property damage resulting from the accidents. The...

  • Evaluation of alternate surfacing systems for temporary and intermittent use roads

    Creator:
    Takallou, Mojtaba B.
    Abstract:
    The purpose of this study was to provide the USDA-Forest Service, Bureau of Land Management (BLM), and other agencies or industries that may deal with temporary and intermittent use roads with the necessary background information for the identification, economic evaluation, and selection of the alternate surfacing systems and to determine...

  • The performance of drivers with physical limitations at T-intersections

    Creator:
    Hunter-Zaworski, Katharine M.
    Abstract:
    The research examines the effect of restricted head and neck movement on driving performance as measured by decision time at T-intersections. The traffic safety and human factors literature was reviewed, and very little was found concerning drivers with physical limitations. T-intersections were selected for study because most accidents involving drivers...

  • Low volume grade crossing treatments for the Oregon high speed rail corridor

    Creator:
    Zaworski, David D.
    Abstract:
    This study defines the information gathering and communication and response needed for safety at highway-rail crossings. It examines technologies for low-cost, high-safety treatments for low volume highway crossings of higher speed (130-200 kph) rail. Crossing closure and consolidation is a necessary first step. Existing train control and crossing safety systems...

  • FATE group decision support system in transportation decision making

    Creator:
    Taekratok, Thaweesak
    Abstract:
    Two interesting challenges have been created in the traditional transportation planning process through recent adoption of more interactive roles by Federal, State and local transportation agencies and of those representing the communities being impacted by proposed transportation projects. First, the decision-making groups that formerly included solely transportation and related professionals...

  • Road design process for low volume recreation and resource development roads

    Creator:
    Kramer, Brian W.
    Abstract:
    This study presents a rational process with supporting data to establish appropriate road design controls, criteria, and standards for low volume recreation and resource development. Much of the information presented can be used to supplement design data presented in a National road design policy published by the American Association of...

  • Trade-offs between geometric design standards and safety for low volume roads

    Creator:
    Kornsombut, Aram
    Abstract:
    Geometric design standards have not been developed specifically for low volume roads. Design standards and criteria are extrapolated from higher standard roadways that are often not relevant to low volume roads. Safety is a primary criterion used for selection of design standards along with economic, financial, social and environment factors....

  • Computerized safety analysis technique for secondary highways

    Creator:
    Nichols, Kevin Scott
    Abstract:
    Evaluation of the safety hazards along a highway is usually performed at specific locations and on known hazards. But, it is also important to find any unrecognized hazards and their locations. Many factors contribute to accident potential, and the combined effect of several of them could produce a hazard that...
