Travel Demand Model

Ozarks Transportation Organization

Springfield, MO

Posted: 01/14/2013
Submittal Deadline: 02/07/2013


Below is a scope of work for RFP #002-2013. For the complete RFP, submission information, and reservations/rights held by OTO please visit

The OTO 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 year (2040). The consultant is then expected to use this data to create a calibrated model of future travel demand on the OTO roadway network. This model is expected to perform within the requirements for air quality modeling as a part of transportation conformity determination.

The Ozarks Transportation Organization travel demand model will have multiple uses once it is complete. These include:
• Congestion Management Process
• Long Range Transportation Plan
• Air Quality Modeling
• Various Traffic Studies, including corridor studies and sub-area plans.

OTO is seeking a 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. OTO 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 OTO. Consultant should also be able to demonstrate expertise and capacity with selected software.

OTO only has the data available as listed. Any additional data needed by the consultant shall be obtained by the consultant, and any related costs thereof are assumed to be part of the rate proposed in response to this RFP. OTO is willing to consider and encourages the use of innovative data sources, such as floating car data, including cell phone or bluetooth data, as well as the Quarterly Census of Employment and Wages and Longitudinal Employer-Household Dynamics data. 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.

OTO currently has access to the following data sources for the travel demand model:
• Reproducible base maps for the urbanized area
• Reproducible base map of the 2010 traffic analysis zones for the urbanized area
• Map of census tracts and block group maps
• 2005, 2008, and 2012 transportation network maps
• The most current land use and zoning maps, including proposed future land use
• List and map of special generators with contact name for special generators
• Most recent Transportation Improvement Program (TIP), 2035 Long Range Transportation Plan, and most recent capital improvement plans
• Available recent aerial photography for the area
• Available GIS files that may expedite the work at the zonal level, including Road Network Shapefiles (may need attention from consultant to be model-ready)
• Travel Time Runs on CMP System
• Traffic Counts

OTO 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.

Selected consultants must possess the expertise and capacity to be able to perform any and all of the travel demand modeling tasks listed below, in addition to any other tasks necessary to complete the project to OTO’s satisfaction:

Task 1. Develop Model Parameters

Task 3. Develop New Model
• Develop new model to 2010 calibration year
• Create network model files

• Summarize all quantification of assumptions
• Deliverables:
o Provide documentation so a knowledgeable modeler can repeat the process and run alternative scenarios
o Report summarizing the model, with review by OTO
o All model files in a digital format ready to be used by consultants for micro-simulations or specific model runs based on additional scenarios

Task 6. Training
• Alternate task
• Include pricing to provide training to OTO staff to do model runs as well as the cost of any software licensing fees and additional equipment if needed.

Task 7. On-Call Model Runs
• Include pricing to accommodate on-call model runs at OTO’s request after completion of this project. This item is not included in the budgeted amount as listed in this RFP. On-call model runs should be completed within 30 days of request by OTO.

Task 8. Model Update in 5-Years
• Should OTO decide to exercise this request, include pricing to conduct one model update in five years time. This item is not included in the budgeted amount as listed in this RFP.

Any additional tasks integral to the modeling process not listed here.

Consultants are asked to propose a project schedule with estimated time to complete each task. Sufficient time must be allowed for agency review and for adoption of the base year and forecast year control totals by OTO. Ability to demonstrate prompt project completion will be considered during the proposal review process.

On or before the 10th of each month, the consultant shall submit a brief progress report describing the work accomplished and technical decisions made during the previous reporting period, and highlighting the work to be completed for during the next period. A percentage estimate of the work completed for each task shall be provided and an estimate of the total percentage of the project should be made.
