REQUEST FOR PROPOSALS
TETON COUNTY, WYOMING TRAVEL DEMAND MODEL
SECTION ONE
INTRODUCTION
General Description and Purpose
The Town of Jackson, Teton County, and WYDOT (the partners) wish to develop a regional
travel demand model for Jackson Hole. Its primary purpose will be to facilitate coordination
between the jurisdictions in planning for traffic and transit alternatives. The intent is the
partners will be able to maintain and use the model in the future to evaluate capital and
operations alternatives, and that the partners update and recalibrate the model in-house, as
necessary.
The Jackson/Teton County community has recently completed a Comprehensive Plan update
and Integrated Transportation Plan (ITP) that rely on a balanced approach to the modes of
transportation as a means of responding to current and forecast transportation demand.
(Current versions of these plans and related planning may be accessed here:
http://www.tetonwyo.org/compp/topics/integrated-transportation-plan/252992/.)
In the past, the Wyoming Department of Transportation (WYDOT) has provided traffic
modeling for the community using its Transcad software. The modelling in the 1991
Transportation Study and the 2000 Jackson/Teton County Transportation Plan that evaluated 4
land use scenarios were done by WYDOT. However, WYDOT is no longer maintaining or
operating a traffic model and the community intends to develop and maintain its own model.
Project Location
The travel model region is mapped below. It is generally defined to the north by Moose and
Kelly, the east by the Town of Jackson, to the south by Hoback Junction, and to the West by
Teton Pass. The model should be designed to specifically model and forecast travel demand
from four specific external origins/destinations: Victor-Driggs in Idaho (Highways22/33), the
Hoback Canyon (Highway 191), Star Valley (South Highway 26/89), and
Yellowstone/Togowotee (North Highway 26/89). Background external travel demand should be
estimated and forecast in conjunction with WYDOT and the National Park Service.

Objectives:
Sean O’Malley, Chairman, Transportation Advisory Committee
(TAC)
This project will develop a regional, multimodal, travel demand model that will support
regional, sub-regional, and project-level transportation analysis and decision making. In
addition, this model shall be:
• A person-trip-based, travel demand model utilizing readily-available and widely-used
software;
• A seasonal model with different versions for average summer demand (June – September),
average ski season demand (January – March), and average off-season demand (October,
November, April and May);
• Fully documented so that it can be locally used, updated, and recalibrated without
consultant support or reliance on proprietary data or inputs; and,
• Calibrated to 2016 actual traffic (for each of the three seasons) within industry-accepted
standards of accuracy.
The initial project will develop a calibrated, documented model based on the existing roadway
and transit networks. This model will be used to forecast person trips, traffic demand and
transit ridership demand for two future scenarios:
• The existing roadway and transit networks including programmed/committed projects
(e.g. proposed improvements to the “Y” intersection in 2017, the 5-lane reconstruction of
South Highway 89, and a roundabout at Gros Ventre Junction); and
• The existing roadway and transit networks plus the Tribal Trails connector and Spring
Gulch Road improvements, and other major capital groups identified in the Integrated
Transportation Plan.
The two scenarios will be modeled to provide forecasts for two horizon years: 2025 and 2040.
Land use input and existing network (GIS) data will be provided by the Town and County. The
project will develop a Traffic Analysis Zone (TAZ) structure appropriate to the population
distribution and travel volumes in Jackson Hole.
Additional considerations:
• The consultant will interact primarily with the Transportation Advisory Committee
(TAC), a group comprised of representatives from the three partner organizations.
• Visitor traffic represents more than half of annual average traffic in Jackson Hole and
about two-thirds of peak summer traffic. This model must explicitly address tourism
generation, visitorship trends and must include input datasets to support forecasting of
visitorship, including lodging units, park attendance and related variables.
• The model may be used in the future to support entry into FTA Small Start planning for
the Town to Village corridor, as described in the Integrated Transportation Plan, and
should be designed to be adequate to that task.

The model will be employed to provide data for more specific traffic simulation studies
in the future and output tables should be designed to facilitate this use. Also, the model
output tables should be designed to address specific monitoring and reporting
requirements identified in the Integrated Transportation Plan., including the reporting
measures identified in Chapter 4 and the traffic counts at benchmark locations described
in Chapter 5 of the Integrated Transportation Plan.
The model will be fully documented in a Manual (printed and digital) and will be
delivered to the partners in a training session for staff, sufficient to support future model
runs and evaluations using in-house staffing and resources.

SECTION TWO
DESCRIPTION OF SCOPE OF WORK AND REQUIRED SERVICES
The objectives of this Travel Model charter will be achieved through the following 4 Tasks.
Task A -
Define Model Assumptions
Before any technical work or analysis is done, the consultant will work with the TAC to define
the purpose of the Model and the assumptions that will define how the model is used. No
model development work will occur until all items in Task A are complete.
Item A1: Review Software Options
The Transportation Advisory Committee will ultimately purchase the software used
to develop the model so that TAC can use, update, and recalibrate the Model with inhouse resources. The consultant will present staff with one or more software options.
The TAC will evaluate each options based on:
• Appropriateness of the software to meet TAC’s needs
• Usability of the interface by TAC
• Inherent assumptions built into the structure of the software
• Reliability and likelihood that the software will continue to be supported
• Compatibility with MapInfo GIS and ESRI GIS software
• Cost

Item A2: Identify and Establish Programmed Assumptions
With any transportation model there are assumptions coded into the model that can
only be changed at a later date with the help of a consultant and/or at significant cost.
The consultant will work with TAC to identify these assumptions. Because these
assumptions cannot be easily manipulated, it is important that the consultant
coordinate stakeholders in the community to review these assumption, early in the
process. This stakeholder engagement will minimize future questioning of model
results and/or model validity.
Item A3: Variable Model Inputs and User/Input Interface
Except for the programmed assumptions, other inputs will be varied by TAC as the
Model is used and updated. Parallel with the software conversation, the consultant
will work with TAC to optimize the user interface. The interface will allow TAC to
enter new data or modify:
• Infrastructure
• Mode share
• Traffic growth
• Land use
• Socioeconomics
Task B -
Data Evaluation and Gathering
Before the model can be developed the consultant will evaluate existing data and data collection
against the Model goals established in the first task. Secondly, the consultant will fill in the data
gaps and provide recommended data maintenance protocols, which may include new data
collection efforts. Task B may occur concurrently with Task A.
Item B1: Evaluate Existing Data to be used in the Model
The consultant will provide TAC with a list of needed data inputs based on the
software and Model structure determined in Task A. The TAC will respond by
providing existing data, including information on how regularly the data is updated.
For reference, the TAC has the following information:
• Traffic Analysis Zones (not updated since 2000)
• Land Use (audited in 2012, updated annually based on building and use permit
data)
• Mapped Roads, Bus Routes, Pathways, and Sidewalks (updated through 2014)
• WYDOT Traffic Counts (reported on an daily/annual basis)
Item B2: Collect missing data
Where data needed for the Model does not exist, the consultant will gather the data,
suggest proxy data, or, for data that is more easily secured by TAC, the consultant will
request TAC compile the data and/or update existing data. Once all data has been
compiled, the consultant will document the data collection methodology (including
the methodology for updating existing data) for inclusion in the Final Model
Description.

Travel Demand Model RFP
June 5, 2017
Item B3: Update and/or revise Traffic Analysis Zones
TAC has existing Traffic Analysis Zones that were used for earlier traffic models.
These zones may not be appropriate for the new model. The consultant will evaluate
these zones and recommend Traffic Analysis Zones appropriate TAC needs. The
Traffic Analysis Zones used in the model should be sized and located to reflect the
realistic mode share of the area they include.
Task C -
Model Development
Once the Model is fully defined through Tasks A and B, the consultant will develop, calibrate,
and verify the Model. The final step of model development will be to compile all components of
the Model Description produced throughout the Tasks into a final document.
Item C1: Develop, Calibrate, and Validate Model
With all of the information from Tasks A and B, the consultant will develop the
model. The TAC anticipates that this will be a significant item in terms of time and
resources, but also realizes that it is an item where the TAC has little involvement. The
consultant will calibrate the Model to 2013 data. 2013 will be used as the base year for
consistency with the Integrated Transportation Plan. Once the Model is calibrated, the
consultant will compare the Model’s output against 2016 actual data to ensure the
model’s validity. The consultant will recalibrate the model if the variation between the
actual data and Model output is greater than 5%-10%.
Item C2: Final Model Description
The consultant will combine all documentation from Tasks A, B, and C into a single
document that provides technical description of the model and justification for the
assumptions.
Task D -
User Training
The consultant will finalize the user interface and provide training on model (and software)
using actual model runs.
Item D1: Capital Group 1/3 Project Modelling
TAC will use the model under realistic conditions in order to evaluate the user
interface. The consultant will do a model run for Tribal Trails (Capital Group 1)
combined with Spring Gulch Road Improvements (Capital Group 3), as described in
the Integrated Transportation Plan. The model run will include analysis of each of the
individual projects as well as modelling of the projects in combination. The consultant
will create a video tutorial from the model run that can be used by the TAC as a
training tool.
Item D2: Interface Refinement and User Manual
When the Model output and tutorial is presented to the TAC there will be a user
interface evaluation. Based on the user interface evaluation, the consultant will refine
the interface and video tutorial for Capital Group 1 and then create a user manual.
The User Manual is a separate document from the Model Description. The audience
Page 7 of 11
Travel Demand Model RFP
June 5, 2017
for the User Manual is the future TAC member that was not part of this process but is
asked to run a project or project alternatives through the model. The User Manual will
be used in conjunction with the video tutorials.
