Firmware and Software Development for Traffic Signal Controllers

The contract seeks the development and delivery of embedded firmware and software for traffic signal controllers that must fully comply with NEMA TS 3.2 at Conformance Level 2 and NEMA TS 3.3 Class B profile standards, ensuring interoperability and functionality within established U.S. transportation protocols. Central to the requirement is the implementation of NTCIP communications to enable real-time data exchange, remote management, and system integration with existing traffic management infrastructure, requiring robust, secure, and reliable software architecture tailored for outdoor, high-reliability environments. The solution must support all mandated functionalities defined by these standards including signal phase and timing control, detector interface handling, and network communication protocols without proprietary dependencies. The work is structured as a subcontract under the Texas Department of Transportation and must be delivered by the response deadline of August 21, 2026, with proposals due no later than 9:00 PM Central Time. The North American Industry Classification System code 511210 indicates the focus on software publishers, aligning the effort with custom software development rather than hardware manufacturing. Performance is expected to occur within Texas, though specific locations are not detailed in the posting, and the contract is open to qualified subcontractors without set-aside preferences. The solicitation is publicly accessible through the Texas SmartBuy portal, and bidders must ensure full alignment with NEMA and NTCIP specifications to meet compliance criteria and avoid rejection.
