The Lawton Metropolitan Planning Organization requests submission from firms interested in being selected to develop a travel demand model for the Lawton Metropolitan Area Transportation Study (LMATS) Area that is also supportive of transportation conformity air quality modeling requirements.  The LMATS area consists primarily of the city limits of Lawton, Oklahoma, but does include some unincorporated areas of Comanche County, Oklahoma.  The LMPO intends to select one firm to provide services as outlined below.  The LMPO receives federal and state grant funding and other funding from local governmental entities.


The Lawton Metropolitan Planning Organization (LMPO) is the designated metropolitan planning organization that serves as a forum for cooperative transportation decision-making by state and local governments and local transportation and planning agencies. MPO’s are charged with maintaining and conducting a “continuing, cooperative, and comprehensive” transportation planning and project programming process for the MPO’s study area.  The study area is defined as the area projected to become urbanized within the next 20 years.

The LMPO is responsible for developing, maintaining, and applying the travel demand model for the LMATS area.  The existing model was developed in 2007 in TranPlan 9.0 software program.  The new model should be able to forecast travel demand for multiple modes of transportation and meet current air quality modeling requirements.  The LMPO does not have current household, workplace, or external station surveys.

The LMPO is seeking a qualified consultant to collect socio-demographic and transportation network data at the traffic analysis zone (TAZ) level for the base year (2010) and the long-term (2040).  The consultant is then expected to use this
data to create a calibrated model of future travel demand on the LMPO street network.  This model is expected to perform within the requirements for air quality modeling as a part of transportation conformity determination.

The LMATS area contains approximately 64.5 square miles and approximately 95 Traffic Analysis Zones. A map of the TAZs and the LMATS Functional Classification Map can be found at:    


The LMPO travel demand model will have multiple uses once it is complete.  These include:

  • Long Range Transportation Plan
  • Air Quality Modeling
  • Land Use Plan
  • Various traffic studies 

The LMPO is seeking multi-modal travel demand model that will fit the above purposes.  The model must meet air quality modeling requirements and generate outputs appropriate for use in the EPA MOVES air quality modeling software.  The LMPO does not have a preference for the software which will run the model.  As part of the proposal, the consultant is expected to name the preferred modeling software and explain why it is the most appropriate fit for the LMATS
Area.  Consultant should also be able to demonstrate expertise and capacity with selected software.

The LMPO has only the data available as listed.  Any additional data needed by the consultant shall be obtained by the consultant, and any related costs are assumed to be part of the rate proposed in response to this RFP.  Consultant is expected to describe the data to be used, the potential source or methodology for sourcing said data, and the
associated data procurement costs.

Data and Information to be Provided by the LMPO

The LMPO currently has access to the following data sources for the travel demand model:

  • Base maps for the urbanized area
  • Base map of the 2010 traffic analysis zones for the LMATS Area
  • Census tract and block group maps
  • 2013 Functional Classification Maps
  • Current land use and zoning maps
  • List and map of special generators
  • FFY 2013-2016 Transportation Improvement Program
  • 2035 Long Range Transportation Plan
  • 2012 City of Lawton Capital Improvement Plan
  • Traffic Counts obtained through the Oklahoma Department of Transportation
  • Any GIS files within the City’s system that may expedite the work

The LMPO does not have any specialty survey data including household, worksite, or external station survey data.  If this or any additional data is required for the production of the model as proposed, the costs of data procurement should be included in the proposal.

Consultant will be expected to perform or procure the following:
