Why locking into closed software contracts is a threat to AI in highways

4 min read by Triopsis 8th October 2025

Imagine this: a local authority signs a 10-year contract with a software provider. They invest heavily in the system, integrate many workflows, and train staff. A few years in, a breakthrough AI scheduling tool arrives that could transform operations across highways but it can’t plug in because your contract forbids external integrations or charges you per API call. The innovation you paid for is locked out.

The risk in restrictive contracts

Long-term software agreements are common in the public sector as they reduce perceived risk, promise stability, and bundle services. But when they include closed systems or API access restrictions, they become barriers to progress:

  • You lose flexibility — as new technologies emerge (especially AI), you can’t adopt them because your core software doesn’t allow it.
  • Innovation slows or stops — your provider’s roadmap defines what you can do, not your own strategic needs.
  • You pay hidden costs — some vendors charge separately for API access or integrations.
  • You can’t adapt readily — if the vendor’s performance lags or they fall behind in updating their platform, your organisation is stuck.

In the highways sector, where dynamic scheduling, route optimisations, predictive maintenance, and real-time decision support matter, the ability to adopt and integrate new AI models, optimization engines, and data sources is critical. A closed contract can stifle all that potential.

Why open APIs matter (and free ones even more)

Software systems should be built to connect. That means open, free-to-use APIs must be a baseline, not an optional add-on. When APIs are unrestricted:

  • You can integrate niche AI tools that specialise in traffic modelling, predictive demand, or scheduling optimisation.
  • You can layer best-of-breed systems without replacing your core platform.
  • You aren’t locked into one vendor’s ecosystem — data portability and interoperability become real.
  • You can evolve as technology shifts, without ripping everything out and starting over.

This isn’t just about one product or one provider: it’s about all technology. Every software vendor should support open integration. Otherwise, you build walls around your systems when you should be laying bridges.

The public sector context: AI, policy and responsibility

In the UK, the government is pushing for AI adoption across public services. The AI Opportunities Action Plan emphasises scaling AI in the public sector, fostering innovation while ensuring governance, and positioning the UK as a leader in AI. GOV.UK

Likewise, the National AI Strategy underscores that AI must be embedded in all sectors, but supported by pro-innovation regulation, access to data, and infrastructure.

However, actual adoption faces real obstacles. A UK Parliamentary report on AI warns that legacy systems, poor data quality, and lack of integration capacity are among the top barriers. UK Parliament If software is locked behind closed contracts, those obstacles become immovable.

What local authorities should demand (and check for)

If you’re procuring software (especially for highways, infrastructure, scheduling), insist on:

  1. Open, free APIs — no paywalls, no extra licences for integration.
  2. Data portability and standards — ensure your data can move, migrate, or be accessed by other systems.
  3. Modularity and extensibility — the software should accept third-party modules or AI plug-ins.
  4. Exit and transition clauses — if the contract ends or the vendor fails, you should be able to migrate without crippling cost.
  5. Right to integrate future tech — ensure clauses explicitly allow integration with new AI or optimisation tools.

Conclusion: Don’t let tomorrow be locked out

The highways sector is poised for transformation. AI can enable smarter routing, cost-effective scheduling, predictive maintenance, and responsive operations. But all that potential hinges on your ability to connect, adapt, and integrate not stay locked in.

Before you sign any long-term contract, ask: will this software let me innovate over time, or will it shut me in? The difference may define your organisation’s future.
