Q-Free, a specialist in mobility solutions for smart city infrastructure, has launched Dynamic Signals, the first local traffic signal controller software built to a modern standard of cybersecurity. Designed for today’s connected world, Dynamic Signals sets a new benchmark for cybersecurity, interoperability, and ease of management—delivering the secure, future-ready solution agencies have been waiting for.
Raising the bar for cybersecurity in traffic control
Traffic signal controllers have long relied on outdated and insecure protocols like SNMPv1, leaving critical infrastructure vulnerable. Dynamic Signals redefines local traffic control with end-to-end encryption, secure API-based communications, and advanced authentication methods, making it the only controller software designed to address modern IT security standards:
Secure, encrypted communications between Q-Free controllers and central systems prevent unauthorized access and data breaches, using similar technology to what powers online banking.
Both online and offline authentication is supported, allowing agencies to seamlessly manage access to large networks of controllers with Q-Free’s Kinetic Mobility platform used for centralized user permission management.
Leveraging the Identity and Access Management (IAM) features of Kinetic Mobility, Dynamic Signals allows agencies to manage all users through their existing systems, like Microsoft or Google accounts, allowing for single sign-on (SSO) and multi-factor authentication (MFA) to apply to controllers. If an employee is removed from the agency’s IT system, their access to the controllers is automatically revoked, eliminating security gaps.
Designed for IT and traffic engineers alike
“For too long, traffic engineers have operated in a way that is disconnected from IT security requirements,” says Whitney Nottage, P.E., PTOE, EVP of traffic management at Q-Free. “That ends now. Dynamic Signals is built to be the first traffic signal software to provide the cybersecurity your agency needs, the protection your IT department expects, and the signal functionality your engineers love.”
Beyond security: Everything you love, now on a secure platform
Dynamic Signals introduces essential cybersecurity measures—like encryption and secure authentication—into an industry where they’ve long been missing, while preserving the trusted functionality of Q-Free’s Msoftware in a more secure and modern platform.
The software features a modern web-based user interface that provides a sleek, intuitive interface making traffic signal management simpler and more efficient than ever.. It includes advanced traffic control features built on the comprehensive local control logic of Maxtime, providing the same trusted functionality with next-generation security.
Dynamic also offers future-ready expansion capabilities serving as the foundation of Q-Free’s next-generation controller ecosystem. Future enhancements will bring advanced solutions like Connected Vehicles (CV), ramp metering, and adaptive signal control into the same secure platform, making it easier than ever for agencies to scale their capabilities.
Q-Free will debut Dynamic Signals at Booth 911 during ITS World Congress, taking place August 24 – 28, 2025, in Atlanta, Georgia. This marks the first opportunity for attendees to experience the new cybersecurity-focused signal controller software live and in action. Interested parties are also invited to register for an exclusive virtual launch event on September 11, 2025.
