Manipulation and Analysis

48
GIS manipulation and analysis functions are vital for decision-making and planning. These activities range from data retrieval tasks, such as selecting information based on specific criteria, to advanced analytical techniques that address complex spatial problems.One critical GIS analysis method is overlaying, which combines multiple data layers to examine impacts. For example, overlaying a river-dammed lake boundary with road networks can identify affected infrastructure. Another common...

    Area of Science:

    • Public health
    • Transportation accessibility
    • Disability studies

    Background:

    • Federal laws mandate equal public transportation access for people with disabilities, yet significant barriers persist.
    • Inconsistent accessibility information on transit websites hinders transportation planning and usage for individuals with disabilities.
    • This study addresses the need to document and disseminate public transportation accessibility data.

    Approach:

    • Reviewed accessibility information from 26 major US public transportation systems.
    • Developed a scoring system based on universal design principles across six dimensions: facility, vehicle, policies, rider accommodations, paratransit, and website accessibility.
    • Disseminated findings through an open data platform for public access.

    Key Points:

    • The average overall accessibility score was 31.9 out of 62.
    • Scores varied widely across dimensions, with facility and vehicle accessibility scoring lowest.
    • While paratransit and website accessibility were often fully scored, other areas showed significant gaps.

    Conclusions:

    • A novel scoring system revealed substantial inconsistencies in public transportation accessibility information online.
    • Public transportation websites are critical for users to access objective information and plan travel.
    • The lack of comprehensive accessibility data online erects barriers, impeding equitable access to public transit for the disability community.
