Rolling Plains Management Corporation (RPMC) is a rural transit district authorized by Texas Transportation Code Chapter 458 in 1980 and therefore receives state funding for rural transit services. RPMC, through its transportation program, SHARP Lines Rural Public Transportation, serves rural areas of Wichita County and all of Archer, Baylor, Cottle, Foard, Hardeman, Jack, Wilbarger, and Young Counties. The urbanized area (UZA) of Wichita County is the Wichita Falls UZA, which is served by the Wichita Falls Transit System (known as Falls Ride).

RPMC operates demand-response service for the general public throughout the state-funded service area. RPMC also provides non-emergency medical transportation for eligible Medicaid participants in the state-funded service area, as well as Clay County and urbanized areas of Archer and Wichita Counties. The private intercity bus line of TNM&O Coaches passes through RPMC’s service area with a station at Wichita Falls.

The RPMC Board of Directors governs SHARP Lines Rural Public Transportation. The board of directors is composed of 24 members, one-third of which are local elected officials, one-third of which are low-income representatives, and one-third of which are private-sector representatives.
