CTP Focus

The CTP also serves as a framework for selecting future transportation projects for the Metropolitan Transportation Plan (MTP), which identifies transportation projects prioritized for funding over the next 20 years.


The CTP includes four maps that illustrate how communities assess and envision their future transportation network.

  1. The Highway Map describes and assesses the transportation network for motor vehicles (not including local and subdivision streets).
  2. The Pedestrian Map describes and assesses the network of sidewalks and trails.
  3. The Bicycle Map describes and addresses the network of bicycle lanes and trails.
  4. The Public Transportation and Rail Map describes and assesses the public transportation and freight rail networks.

PDF Maps

The PDF CTP maps are the officially adopted maps by CRTPO and the NCDOT Board of Transportation. Printable PDF versions of the adopted maps are available in each ‘panel’ of the PDF map.

Improvement Types

Each map examines a variety of facility types appropriate for that portion of that transportation network and categorizes each facility in one of three manners:

The existing facility meets current needs. The facility may be considered adequate based on a variety of factors, such as appropriate design, expected future traffic volumes, consistency with adopted plans, or livability objectives. The facility may also be considered adequate based on its context within the larger transportation network or because it is unbuildable due to physical constraints.

The existing facility or service is (or is expected to be) inadequate and should be changed to accommodate expected traffic volumes, improve inadequate design or identified safety issues, reflect pedestrian and bicycle facilities shown in adopted plans, improve poorly designed facilities, or fill in connectivity gaps.

There are no existing facilities or services and a new facility or service is needed.

How are changes made to the CTP?

The CTP is a dynamic plan for the long-term future and will evolve to reflect changing conditions, e.g. a street segment or sidewalk is built, or local plan and policy changes. Future amendments to the CTP are made through a mutually agreed-upon process in coordination with CRTPO and its member jurisdictions.

There are two types of amendments that can be made to the CTP: Administrative and Procedural.

Administrative Modifications reflect minor changes to alignments and changes in status from either Recommended or Needs Improvement to Existing. Such changes can be made by making informational presentations to the TCC and the CRTPO Board.

Procedural Amendments encompass a variety of more substantial changes to the transportation network, including but not limited to adding or removing a facility, changes in a facility’s status to either Recommended or Needs Improvement, or a change in facility classification. Procedural amendments require public engagement and CRTPO Board adoption to be finalized. The CTP Amendment Guidelines were updated as part of the 2022 update to the CRTPO’s Public Involvement Plan. This update included coordination with the CTP Work Group to update the language and strategies identified.

  1. Staff from the CRTPO member jurisdiction initiates the process by coordinating with CRTPO staff to verify and confirm the request is an administrative modification.
  2. The proposed modification will be presented by the member jurisdiction at a Transportation Staff Meeting (TSM) for information.
  3. Pending any comments from TSM, the modification is conducted internally without action from the TCC and CRTPO Board.
  4. CRTPO staff will present a comprehensive list of modifications to the TCC and CRTPO Board meetings once a year.
  5. NCDOT staff brings a list of all amendments once a year to the NC Board of Transportation Meeting for inclusion within the statewide CTP.
  1. Staff from the CRTPO member jurisdiction initiates the process by providing a map of the proposed amendment and coordinating with CRTPO staff to verify and confirm the request is a procedural amendment.
  2. If confirmed, the member jurisdiction staff will conduct a presentation during a TSM for information and/or discussion as needed.
  3. Provided no significant issues are identified during the presentation at TSM, the request will move to an upcoming TCC Meeting for information to recommend that the Board open a public comment period on the proposed amendment. Board approval of the request is required to start the public engagement period. The member jurisdiction must lead the public engagement process. The public engagement period is preferred to be 30 days in length if meeting schedules permit, with a minimum 14 days.
  4. Following the close of the public comment period, member jurisdiction staff conducts a second presentation at TSM to summarize the comments received.
  5. Member jurisdiction staff provides all agenda text, attachments and presentations to be included within an upcoming TCC and CRTPO Board agenda to present a summary of the comments received.
  6. NCDOT staff brings a list of all amendments at least once a year to a NC Board of Transportation meeting for inclusion in the State CTP plan.

Other Resources 

The CTP Report was developed in early 2020 to enhance the CRTPO’s consistency with the state’s CTP planning process. The report is intended to serve two purposes: 

  1. It provides documentation and support for the multi-modal transportation network assessment identified in the adopted CTP maps. This documentation and support will inform project development and funding at the state (MTP, STI) and local (discretionary funding) levels. 
  1. The CTP serves as the NCDOT’s primary reference for Complete Streets-eligible facilities, as required by NCDOT’s Complete Streets policy (adopted August 8, 2019). Local multi-modal facility recommendations, included by reference within the text of this document, inform NCDOT’s Integrated Mobility Division, Transportation Planning Division, and appropriate Division Engineers, of locally adopted transportation network intent and design. 

In 2019, the Centralina Council of Governments (now Centralina Regional Council) prepared a white paper on the CTP. A Comprehensive Transportation Plan Work Group was formed to evaluate the report findings. The final report can be viewed here: “Have the Rules Changed? A White Paper on Implementing the CTP and Corridor Preservation.”

What is the Comprehensive Transportation Plan?

The CTP is a planning requirement of North Carolina General Statutes §136-66 to serve present and anticipated travel demand in and around cities and towns throughout the state.

It represents the community’s long-term vision for how the local transportation network should evolve to serve residents and employers in a growing region.

The CTP includes multiple modes of transportation: highways, pedestrian facilities (sidewalks and trails), bicycle facilities, public transportation, and rail. Attention to each of these transportation modes allows us to better provide for a broad range of transportation choices.

The CTP assesses the condition of the entire transportation network and serves as the framework for transportation planning efforts at the local and regional scales. By including all modes of travel (not just cars), the CTP provides a comprehensive inventory of an evolving multi-modal transportation network to support CRTPO and its local partners as they plan to meet the needs of a growing and diversifying population. The CTP does not include specific transportation projects or improvement schedules, but instead represents the status or completeness of the comprehensive transportation system

Who provides information for the CTP? 

Local jurisdictions in the CRTPO region determine the completeness of each segment of highway (or street), pedestrian facility, bike facility, or public transportation network, based in large part on locally adopted plans, policies, and expectations for the future. The segments are categorized as existing, needs improvement, or recommended. An explanation of the categories is provided below.

How does the CTP impact future transportation plans and projects? 

By establishing the region’s future transportation needs, the CTP offers an organized way to identify, and eventually prioritize, the transportation projects that will be built in the communities that comprise the CRTPO. Local governments may use the CTP to inform local land use decision-making and transportation planning initiatives and to more clearly communicate transportation expectations with residents, developers, and NCDOT. 

The CTP also serves as a framework for selecting future transportation projects for the Metropolitan Transportation Plan (MTP), which identifies transportation projects prioritized for funding over the next 20 years. Once projects are in the MTP, projects are then selected to be placed in the even shorter-term Transportation Improvement Program (TIP) that NCDOT uses to program projects for construction. 

Which portion of the CTP is adopted? 

The CRTPO policy board and the North Carolina Board of Transportation mutually adopt the four locally-produced CTP maps. This allows for the multi-modal CTP to be used for MPO planning processes. 

How is the CTP implemented? 

The CTP is implemented in a variety of ways, since there are several methods by which highways, streets, pedestrian, bike, and public transit facilities get built. Transportation projects can be built or improved as public construction projects or in conjunction with land development projects. 

Generally, segments shown as “Needs Improvement” or “Recommended” could become a project in the MTP, a locally-funded project, part of a development project, or may never become a project. 

How might local jurisdictions implement the CTP? 

  • The CTP designations can help local jurisdictions develop, prioritize, and plan local projects; 
  • The CTP can assist with coordinating transportation planning efforts that fall within multiple jurisdictions; 
  • The CTP designations help jurisdictions more clearly communicate the local transportation vision by including multiple transportation modes; and 
  • Local jurisdictions can implement improvements through local ordinances or capital projects. 

How will the CRTPO implement the CTP? 

  • The MTP will draw from the CTP for potential projects; 
  • The CTP maps and supporting documentation will be used to track historical information about the transportation network; 
  • The information in the CTP will help define expectations when the CRTPO is working with the State on project designs; and 
  • The CTP will serve as a source of information to ensure that future projects reflect the community’s transportation vision. 

How will NCDOT implement the CTP? 

  • NCDOT will use the CTP designations to develop future, funded transportation projects. 
  • The multi-modal CTP will help NCDOT better understand the comprehensive transportation vision for local jurisdictions and the CRTPO.
