Passenger Transportation Plan

The Passenger Transportation Plan (PTP) process for Iowa’s 9 Metropolitan Planning Organizations (MPOs) and 18 Regional Planning Affiliations (RPAs) is designed to promote joint, coordinated passenger transportation planning programs that further the development of the local and regional public transportation systems. Public transportation systems in Iowa include the 35 public transit systems PLUS a wide array of human service and private transportation providers. The goals are: 1. Improve transportation services to Iowans 2. Increase passenger transportation coordination 3. Create awareness of unmet needs 4. Develop new working partnerships 5. Assist decision-makers, advocates, and consumers in understanding the range of transportation options available 6. Develop justification for future passenger transportation investments 7. Save dollars and eliminate overlapping of services The PTPs are an Iowa creation, providing needs-based justification for passenger transportation projects and as well as incorporating federal requirements for coordinated planning.
