The Technical and Freight Planning (T&FP) Unit manages freight planning efforts, including maintaining and guiding implementation of the New Mexico State Freight Plan, and coordinating with freight partners;

maintains roadway classification systems, including the Functional Classification System, National Highway System (NHS), and freight-specific classifications; and provides technical support including maintenance of the New Mexico Statewide Travel Demand Model (NMSTDM).

2045 New Mexico Freight Plan

The New Mexico Department of Transportation (NMDOT) updated the New Mexico Freight Plan in 2023, with input and guidance from the Freight Advisory Committee and other statewide planning partners. With this plan, NMDOT re-established the vision of how New Mexico maintains and improves the condition and performance of the multimodal freight network in the state.

New Mexico Travel Demand Modeling

Travel Demand Modeling

The Technical and Freight Planning (TFP) section maintains and operates the New Mexico Statewide Travel Demand Model (NMSTDM). This is done to provide baseline data for descriptive and planning purposes, and to provide an analytical tool for estimating the impact of potential transportation projects within the State of New Mexico. TFP collaborates with engineers and planners at NMDOT, as well as with professionals from other Tribal and local public agencies. The purpose of this modeling tool is to assist decision makers in determining whether proposed projects are scaled appropriately for the needs of the travelling public, and where resources can best be directed for cost effective outcomes.

The NMSTDM produces data by estimating and forecasting Traffic Volumes, Traffic Speed, Vehicle Hours Travelled (VHT), and Vehicle Miles Travelled (VMT) for passenger vehicles, as well as medium and large freight vehicles. Volume to Capacity ratios (V/C) are available for combined total traffic on road facilities. Additional data may be generated based on the specifics of a model run request.

Data can be produced for the NMSTDM’s base year (2023), and in future years (2025, 2030, 2035, 2040, 2045 & 2050) to forecast changes in travel demand over time. However, the model road network used by the NMSTDM is a subset of the entire New Mexico road network. It includes all major and most mid-sized roads.  Low volume local roads are typically not represented in the model network with that traffic captured by other roads.

A primary feature of the NMSTDM is that it allows planners and engineers to model alternative project scenarios. This provides a contrast between expected travel demand in a given year and how demand may be different if a project is implemented. This is accomplished by comparing model results of a No-Build scenario to a Build scenario. Typical modelling scenarios involve adding or removing a roadway facility, or changing the speed, capacity and/or access of road facilities. Often there are multiple Build scenarios (or alternatives) associated with a potential project. The NMSTDM can compare and contrast these Build scenarios to help refine the scope of the project.

Data sources that were used for this work include roadway network and traffic count data produced by the NMDOT Data Management Bureau, travel data from commercial vendors, and socio-economic data from the U.S. Census Bureau.

How to Request Modeling from NMDOT

Modeling services are available for the use of New Mexico governmental agencies, and contractors performing services for those New Mexico agencies. Contractors should work through their governmental agency contact to initiate the request.


Please contact the Travel Demand Modeler at to receive a Travel Demand Model Data Request Form with Instructions. The Travel Demand Modeler is also available for questions, and assistance in filling out the model run request form by email or by phone at (505) 365-3583.

Request for Change of Roadway Functional Classification

Instructions & Change Request Forms

Requests for change to a roadway’s functional classification must originate from the tribal or local public agency (T/LPA) that owns the roadway. In the case of state-owned roadways, the request must originate from the NMDOT District that the roadway is within.

If you are a T/LPA or NMDOT District staff member who would like to request a change to a roadway’s functional classification, use the form below:

Functional Classification Change Request, Part 1

Once submitted to NMDOT’s Functional Classification Manager, Part 1 of the request will be approved or denied based on the information provided in supporting documentation. Refer to the following guidance documents for information about factors that can justify a change of functional classification:

After approval by the NMDOT Functional Classification Manager, Part 1 of the request and all supporting documents will be forwarded to the respective MPO or RTPO for the area in question. MPOs/RTPOs must approve the requested change using the form below:

Functional Classification Change Request, Part 2

Following approval by NMDOT’s Functional Classification Manager and the appropriate MPO/RTPO, the requested change must also be approved by the FHWA-NM Division Office.
