Summary
COUNCIL GOAL: Direction for Strategic and Economic Growth
(2B: Continuously provide a high level of customer service to our citizens)
MEETING DATE: November 19, 2024
DEPARTMENT: Development Services / Engineering
CONTACT: Gary Graham, PE, PTOE, Director of Engineering

RECOMMENDED CITY COUNCIL ACTION:
• Approval of Resolution
ITEM SUMMARY:
• This Resolution authorizes the City Manager to execute a contract with Kimley-Horn and Associates, Inc. (KHA) for professional engineering services to develop the Citywide Travel Demand Model (TR2525) and authorizing all necessary change orders under said contract up to an aggregate contract amount, inclusive of any change orders, not-to-exceed $299,750.
BACKGROUND INFORMATION:
• The Travel Demand Model (TDM) will encompass the entire City limits and ETJ areas. This model will be used as part of the upcoming Roadway Impact Fee Update study and future signal timing studies.
• Kimley-Horn and Associates, Inc submitted a response to 24-14RFQ Category IV - Traffic Studies/Services. They were one of six firms shortlisted by City Council on March 5, 2024. Kimley-Horn and Associates, Inc was selected from this group based on availability and qualifications to conduct traffic studies and modeling.
• The Base Year travel demand model will be developed using general parameters from the North Central Council of Government (NCTCOG) regional travel demand model.
• KHA submitted a proposal for $272,500 for professional engineering services to develop a TDM, that includes the following tasks:
o Task 1 - Base Mapping and Data Collection
§ Review and summarize counts from the City’s data dashboard to be used in the model validation process.
§ Utilize available big data sources (i.e. Replica) to establish origin-destination routes and volumes throughout the model study area.
§ Review comprehensive plans and thoroughfare networks from surrounding municipalities and Collin County to ensure the external model network is consistent with other plans.
o Task 2 - Base Year Model Development and Calibration/Validation
§ Develop a base year model highway network of all existing City thoroughfares as identified on the current Master Thoroughfare Plan (MTP). Any roadways that were under construction and open to traffic in 2023 will be accounted for in the base year modeling.
§ Develop base year traffic analysis zones (TAZs), using the MTP as a basis for the zone boundaries. This exercise will use NCTCOG boundaries as a base and break into smaller zones.
§ The base year traffic assignment will be run using TransCAD.
o Task 3 - Future Year Modeling (Build-Out and 10-Year)
§ Develop a base Build-Out travel demand model that covers the study area limits and develop a future year model highway network to include all City thoroughfare roadways at full build-out based on the currently adopted MTP.
§ NCTCOG travel demand model future year scenarios will be used to adjust the external zones target volume to ensure that regional roadway projects are accounted for in the sub-area model.
§ Develop a modified Build-Out travel demand model to include thoroughfare modifications. The modified Build-Out model will be run using the proposed MTP network.
§ Develop a 10-Year travel demand model that uses the proposed MTP network and 10-year land use projections provided by the City that will be accumulated within the TAZ structure.
o Task 4 - MTP Mapping
§ Develop an updated map showing the proposed MTP network. As part of the MTP mapping task, future traffic demands at thoroughfare intersections will be analyzed and reviewed to determine a list of intersection control options and work with the City in identifying intersection projects to include in the MTP maps.
o Task 5 - Travel Demand Model Report
§ Prepare a report that summarizes the travel demand modeling process, validation/calibration, and summary of the future base modeling and scenarios.
o Task 6 - Meeting and Project Management
§ Prepare a Project Management Plan. The plan will include a brief understanding of the project, highlights the project team members involved, and include schedule milestones that assigns target data for each task.
o Task 7 - Scenario Modeling
§ Perform up to five (5) model scenarios using the future travel demand model as directed by the City. A brief memo will be prepared to discuss the results of the scenario testing.
FINANCIAL SUMMARY:
• This Resolution authorizes a professional services contract with Kimley-Horn and Associates, Inc., for a total contract amount not-to-exceed $299,750.
• With approval of this item, $345,250 will remain in project TR2525.
