Q-Free has published its interface control documentation and communication protocols for the Dynamic Signals Application Programming Interface (API).
The move provides integrators, agencies and partners with the information necessary to integrate Q-Free’s cybersecure traffic signal control software into their traffic management systems.
Widely recognised as the global standard for software integration, APIs are what make modern technology ecosystems work - enabling devices, systems and applications to communicate securely and efficiently.
While many areas of intelligent transportation have already adopted APIs, traffic signal controllers have largely relied on legacy protocols.
By publishing the interface control documentation and integration protocols necessary to interact with the Dynamic Signals API, Q-Free said that it brings the same open, secure interoperability found in other smart mobility domains directly to the intersection.
“Dynamic Signals set the bar for secure, modern signal control, and this documentation makes it possible for others to integrate with it safely and reliably,” said Mark Talbot, CEO of Q-Free.
“We believe in interoperability with control, giving agencies the flexibility to integrate their systems while maintaining the highest level of cybersecurity.”
Q-Free said it has built its secure API from the ground up, using modern cybersecurity principles, including encryption and authentication, to prevent interception or impersonation attacks and foster trust across diverse systems.
By publishing the information necessary to interact with Dynamic Signals, Q-Free extends its built-in cybersecurity protections beyond its own platform. This makes it easier for others to innovate and interoperate without compromising security.
Agencies, consultants and third parties within the ITS industry can access the interface control documentation and communication protocols on Q-Free’s website, enabling seamless integration without proprietary dependencies or restrictions.
While the NTCIP standards process is slowly evolving toward SNMPv3 to address security needs, Q-Free’s secure API offers an immediate, real-world solution.
The company remains active in NTCIP committees, but agencies are facing security issues now and Q-Free said it recognised the need to deliver a forward-looking solution that keeps pace with today’s cybersecurity threats.
“NTCIP is pursuing an important goal,” said Whitney Nottage, executive vice president of traffic management for Q-Free.
“But the standards process can be slow and agencies need solutions now. APIs are not a question of if the industry will adopt them, but when. We’re making that future a reality today.”
