Metropolitan Transportation Plan (MTP)

The MTP includes both long-range and short-range strategies/actions that lead to the development of an integrated multimodal transportation system to facilitate the safe and efficient movement of people and goods in addressing current and future transportation demand.  The MPO reviews and updates the transportation plan every five years to confirm the transportation plan’s validity and consistency with current and forecasted transportation and land use conditions and trends. The MTP contains existing and proposed transportation facilities including major roadways, transit, multimodal and intermodal facilities, pedestrian walkways and bicycle facilities, and intermodal connectors that should be included in the Mississippi Gulf Coast’s transportation system.

Congestion Management Process (CMP)

The CMP is a process that provides for effective integrated management and operation of the multimodal transportation system based on performance measures and strategies including travel time data that is used to identify traffic congestion. The CMP leads to recommendations of strategies to mitigate traffic congestion such as demand management measures, traffic operational improvements, public transportation improvements, ITS technologies and where necessary, additional capacity. (Click to View Plan)

The MPO publishes a listing of all federally funded projects that have been obligated. Obligated projects are strategies and projects funded for which the supporting Federal funds were authorized and committed by the State or designated recipient in the preceding program year, and authorized by the FHWA or awarded as a grant by the FTA.

Electronic copies are emailed to stakeholders, MPO members and are available on the GRPC website. Paper copies are made available upon request as well as in the GRPC offices and at local public libraries. Draft plans that have completed the public review process are then submitted to MDOT and FHWA for review and approval before final adoption.
  2. An Amendment is defined as a major revision to the plan. this could include the addition or deletion of a project, changes to project or phase costs, alterations to the design, concept or scope or a major change to project or phase initiation dates. For example changing project termini or increasing the number of traffic lanes being constructed. Amendments require a minimum 10 day public review and comment period and may require an additional demonstration of fiscal restraint and/or a conformity determination.
  3. The administrative Modification refers to minor revision to the plan. This may include minor changes to project initiation dates or minimal added text to provide clarification.
