The purpose of each coordinating board is to develop local service needs and to provide information, advice, and direction to the community transportation coordinators on the coordination of services to be provided to the transportation disadvantaged. Transportation disadvantaged means those persons who because of physical or mental disability, income status, or age are unable to transport themselves or to purchase transportation and are, therefore, dependent upon others to obtain access to health care, employment, education, shopping, social activities, or other life-sustaining, or children who are handicapped or high-risk or at-risk as defined in Section 411.202, Florida Statutes.
