Rapid Flow Technologies is a technology company.
Rapid Flow Technologies develops intelligent transportation systems, primarily its Surtrac adaptive traffic signal control technology. This core product dynamically optimizes traffic flow by adjusting signal timing at intersections in real-time. Surtrac’s capabilities aim to reduce congestion, improve travel times, and minimize vehicle emissions through advanced algorithmic decision-making, enhancing urban mobility.
Stephen Smith and Gregory Barlow founded Rapid Flow Technologies in 2006. Their venture emerged from pioneering research at Carnegie Mellon University’s Robotics Institute. Smith and Barlow sought to commercialize the innovative Surtrac technology, translating academic advancements in artificial intelligence and robotics into practical urban infrastructure solutions for traffic management.
The company serves municipalities and urban centers modernizing their transportation infrastructure. Rapid Flow Technologies’ vision focuses on fostering responsive, sustainable urban environments. By implementing its adaptive control systems, the company enables cities to manage vehicular flow effectively, contributing to smoother commutes and a reduced environmental impact for communities.

Rapid Flow Technologies was a Pittsburgh-based technology company that developed Surtrac, an AI-powered adaptive traffic signal control system designed to optimize urban traffic flow in real-time. It served cities and municipalities by reducing congestion, travel times by 25%, wait times at signals by 40%, stops by 30%, and emissions by 20%, while accommodating vehicles, cyclists, pedestrians, and transit.[1][3][4][5] The company demonstrated strong growth through deployments at over 350 intersections, including partnerships in Ontario and Massachusetts, before its acquisition by Miovision in 2022, integrating Surtrac into a broader traffic management platform.[4][5]
Rapid Flow Technologies spun out from Carnegie Mellon University's Robotics Institute and Traffic21 in 2014-2015 to commercialize Surtrac, a technology blending artificial intelligence, traffic theory, and advanced sensing for second-by-second traffic optimization.[1][4] Key founders included Gregory Barlow (CTO, Ph.D. in Robotics from CMU, focused on distributed intelligent systems for urban transport) and Stephen Smith (CMU Professor), with Griffin Schultz later serving as CEO.[1][3][4] The idea emerged from CMU research addressing inefficiencies in traditional traffic systems, gaining early traction in Pittsburgh to improve local mobility before expanding commercially.[1][3]
Rapid Flow rode the smart cities and intelligent transportation systems (ITS) trend, leveraging AI and IoT sensors to tackle urban congestion amid rising vehicle density and multi-modal demands.[1][3] Its timing aligned with growing municipal investments in data-driven infrastructure post-2010s, amplified by needs for emission reductions and efficient mobility in gridlocked cities like Pittsburgh.[3] Market forces favoring decentralized, retrofit-friendly tech over costly centralized systems positioned Surtrac advantageously, influencing ecosystems by enabling scalable upgrades and paving the way for AV integration.[3][5] The 2022 Miovision acquisition accelerated this impact, merging Surtrac with advanced analytics platforms to modernize global traffic management.[4][5]
Post-acquisition, Surtrac thrives within Miovision's ecosystem, with its Pittsburgh team driving expansions and integrations at sites like Peterborough and Quincy.[5] Next steps likely include broader U.S./global rollouts, deeper AV/bus/pedestrian connectivity, and AI enhancements amid rising smart city budgets. Trends like electrification, shared mobility, and climate mandates will amplify its relevance, evolving its influence from niche innovator to core urban mobility enabler—transforming gridlock into seamless flow, much like its Pittsburgh origins promised.[4][5]
Rapid Flow Technologies has raised $391.7M across 6 funding rounds. Most recently, it raised $260.0M Miovision - Other Equity in April 2023.
