Harnessing Traffic Data: The Next Step In Remote Traffic Management

Technology is changing the way we manage traffic, helping us move from simply reacting to issues to spotting them earlier and making better‑informed decisions. And that shift has real potential to improve the efficiency, safety and sustainability of our road network.

By bringing different data sources together, customers can now:

• Identify congestion hotspots, risky junctions and speeding issues
• Make targeted improvements, from optimising signal timings to redesigning layouts or introducing enforcement locations
• Build stronger, evidence‑based business cases for funding

Data is helping us imagine — and deliver — a future where the impact of roadworks is minimised, traffic flows more smoothly and collisions are prevented, supporting the wider Vision Zero ambition.

This year’s HAUC(UK) convention in Manchester marked the organisation’s 40th anniversary, with a theme of Enabling Future Foundations. As headline sponsor, Ben Parsons, SRL’s Business Development Director, had the chance to share how we’ve been exploring the wider potential of the data captured through our REMOS deployments.

REMOS allows portable signals to be managed off site, improving road worker safety, enabling faster interventions and reducing CO2 emissions. But we’re now seeing that this is only the beginning.

REMOS will soon be able to remotely measure and analyse behaviours on construction sites, including:

• Object counts within defined areas
• Dwell time
• Red light infringements
• Tailgating
• Line crossing 
• PPE compliance

This insight is already helping customers strengthen health and safety standards, understand vehicle behaviour and create safer working environments for site teams.

We’ve recently been trialling red‑light infringement detection on several major UK construction schemes. By setting a virtual stop line aligned with signal phasing, we can record vehicles that cross during a red phase and log these events through our portal. Project teams can then use this evidence to make informed decisions.

The following visuals demonstrate how REMOS detects and records red-light infringements:

On one site, we recorded an average of 375 infringements in a single day — a serious safety risk that had previously gone unmeasured. With this level of clarity, customers have been able to take meaningful action, from adjusting site layouts and traffic management plans to addressing non‑compliant construction traffic and introducing targeted safety measures.
