  • Abstract:
    With the ultimate purpose of enhancing safety and improving mobility, the Statewide Shoulders Study was initiated to

    develop a prioritized list of candidate locations for shoulder improvements. The need for this study stems directly from

    ADOT’s desire to increase safety and mobility along the Arizona State Highway System. The project purpose is

    demonstrated with the following statement of need:

     Create Methodology. As the first statewide, shoulder improvement prioritization project conducted in Arizona,

    a methodology needs to be developed that utilizes available data to accurately identify deficiencies. A

    statewide and district-level prioritization is needed in order to appropriate limited funds for priority projects.

     Develop List of Shoulder Improvement Locations. Currently, there is no statewide or ADOT Engineering

    District-wide listing of prioritized locations for shoulder improvement projects. This document will serve as guidance for determining priority roadway segments within each ADOT District and throughout the State that

    require funding.

     Develop Feasible, Cost Effective Implementation Plan. High priority projects need to be evaluated for

    feasibility and cost-effectiveness. Due to limited funding, innovative and cost effective alternatives beyond

    traditional pavement applications need to be explored.
