National Signal LLC., a leading manufacturer of transportation safety products and ITS Smart Work Zone solutions, is now integrating its HS Connect® software with Flow API for real-time travel time and speed data to power its smart work zone technology. With the Flow API, HS Connect is enhancing its ability to deliver real-time traffic intelligence to DOTs, contractors, and the traveling public — improving safety and mobility in and around work zones nationwide.

How HS Connect® is Using the Flow API

The integration of the Flow API enables Hill & Smith to power key capabilities across its Smart Work Zone product line including:

• Real-Time Travel Time Display – Feeding accurate, live travel time data to portable message signs and variable message boards, giving motorists actionable information as they approach and travel through work zones.
• Queue Detection & Speed Monitoring – Leveraging real-time speed data from the Flow API to detect slowdowns and queue formation earlier, triggering automated warnings that reduce rear-end collisions in work zones.
• Data-Driven Work Zone Management – Providing DOTs and contractors with continuous, probe-based speed and travel time analytics through the HS Connect® platform, enabling smarter operational decisions and post-project performance analysis.

Driving Outcomes for Work Zone Safety

With the Flow API integrated into its Smart Work Zone solutions, HS Connect® can deliver:

• Accurate, real-time travel times for motorists navigating work zones
• Faster queue detection to reduce secondary crashes and improve safety for road workers
• Software-defined data infrastructure that eliminates the need for dedicated field sensors
• Scalable, nationwide coverage from day one — no hardware installation required

“The Flow API gives us a reliable, scalable source of real-time travel time and speed data that we can plug directly into our Smart Work Zone solutions. This means better information for motorists, faster response to changing conditions, and safer work zones.” — Pete Krikelis, VP ITS Development

“HS Connect’s integration of the Flow API into their Smart Work Zone platform demonstrates exactly how modern infrastructure companies are adopting software-defined data to make roads safer.” — Jatish Patel, CEO, Flow Labs.

The result is better information for drivers, earlier warnings when traffic backs up, and safer conditions for the crews working the zones — all from data infrastructure that scales nationwide without new hardware in the field.
