Why TOPAS Matters for Connected Journeys

I read this article about TOPAS on Highways news with interest because it touches a tension I see every day in product decisions. Short-term pressure versus long-term responsibility.

As Head of Product and Solutions at SWARCO UK and Ireland, I spend a lot of my time thinking about what happens after a system goes live. Not just whether it works on day one, but whether it’s safe, supportable, and adaptable for the next ten or twenty years.

From that perspective, standards are not optional. They are foundational.

Our products are TOPAS approved. We actively sit on the TOPAS board and sub-committees. We do this because standards shape product behaviour long before a customer ever sees a feature list or a price.

From a product point of view, TOPAS does three critical things:

• It creates clarity. Engineers know what good looks like. Interfaces behave predictably. Integration stops being a guessing game.
• It enables innovation. When the baseline is stable, product teams can focus on improving outcomes rather than reinventing compatibility. Innovation becomes faster, not slower.
• It protects customers. Systems remain interoperable as estates evolve. Support does not depend on tribal knowledge. Safety assumptions remain intact as components change over time.

When standards are weakened, the product risk increases immediately. You see it in bespoke interfaces, brittle integrations, and workarounds that never quite get documented. Those risks don’t sit neatly in a business case. They surface later in incidents, outages, and safety reviews.

Traffic technology is not consumer tech. These systems influence human behaviour in live environments, at speed, and at scale. From a product responsibility standpoint, safety isn’t a feature. It’s a duty.

This is where our Connected Journeys strategy comes in.

A journey is not a single product. It’s a chain. Junctions connect into corridors. Corridors connect into networks. Networks only function safely when products behave consistently together.

Every connected journey must be a safe journey.

Standards make that possible. They allow products from different generations, suppliers, and disciplines to work together without introducing hidden risk. They give customers confidence that today’s decisions will not constrain tomorrow’s options.
