Replica All-Application Access with Sole Source Conditions

The Illinois Department of Transportation (IDOT) Office of Highways Project Implementation is seeking to procure a sole source contract amendment with Replica, Inc. for All-Application software access to expand the agency's existing statewide travel demand modeling platform. The procurement involves adding specialized scenario-planning applications—including Road Closure Scenario, Safe Streets Planner, and Active Transportation Analysis—that will enable IDOT to evaluate safety outcomes, test infrastructure interventions, and assess system impacts of road closures and multimodal investments across Illinois. The deliverables include browser-based, secure Software-as-a-Service (SaaS) platform access with unlimited organizational access, featuring de-identified and anonymized data integration from multiple sources, privacy-first synthetic population analytics, probabilistic mode choice outputs supporting transit and active transportation policy evaluation, and detailed trip purpose delineation with semi-annual to weekly data updates. The key objective is to support statewide planning initiatives and comply with federal Justice 40 requirements and the National Electric Vehicle Charging Infrastructure (NEVI) program, with required qualifications being Replica's unique combination of capabilities including fully-calibrated travel demand modeling, individual-level traveler characteristics, and integrated scenario-planning applications unavailable from competing vendors. IDOT evaluated alternative vendors including AirSage, StreetLight, and Teralytics but determined them unacceptable due to aggregated data limitations, less frequent update cycles, and lack of integrated scenario-planning applications. The deadline for written comments or requests for a public hearing is Thursday, December 25, 2025 at 4:00 p.m., with the hearing being canceled unless an interested party submits written correspondence by this date; the overall proposal due date is December 30, 2025, and the services are required to commence by January 1, 2026.

This sole source procurement contains no specific set-aside designations or restrictions on organizational type based on the available documentation, and no disadvantaged enterprise requirements are identified. The procurement is structured as a one-time amendment to the existing Replica Data Proprietary Model contract (24-494DOT-FINAD-P-62707), which originally ran from March 4, 2024 through March 3, 2027, with the amendment extending the term through March 4, 2027 to align with the existing contract expiration and including no renewal options. The contract amendment value is $900,000, representing a 4 percent discount applied to the All-Applications upgrade for the remaining 15 months of the subscription period, with funding provided through State Appropriated Funds. IDOT determined the price fair and reasonable by comparing it against the independent cost of acquiring equivalent datasets and performing analyses in-house, which would require substantially greater staff resources. The sole source justification was approved by the State Purchasing Officer on December 15, 2025, with initial posting to the Illinois Procurement Bulletin on December 16, 2025, establishing Replica as the sole economically feasible source due to its unique privacy-preserving methodology, fully-calibrated travel demand model, and integrated applications capabilities that no competing vendor can match.
