Why the DfT's New Strategy Matters for the Future of Intelligent Transport

Resilience has become one of the defining themes of modern transport policy. For much of the past decade, conversations around Intelligent Transport Systems (ITS) have understandably focused on efficiency, automation, digitalisation and decarbonisation. Yet recent events have demonstrated that the ability of transport networks to withstand disruption may be just as important as their ability to move people and goods quickly. The Department for Transport’s newly published Transport Resilience Strategy marks a significant shift in that direction, setting out a long-term vision for how the UK transport sector can anticipate, prepare for, respond to and recover from an increasingly complex range of risks.

At first glance, resilience might appear to sit alongside the digital transport agenda as a separate policy concern. In reality, the two are becoming inseparable. Modern transport systems rely heavily on data, communications networks, connected infrastructure, digital control systems and increasingly sophisticated automation technologies. As transport becomes smarter, resilience becomes more dependent on the performance and security of those digital foundations.

The strategy arrives against a backdrop of recent disruptions that have exposed vulnerabilities across multiple modes. The document points to the lasting lessons of the COVID-19 pandemic, the storm damage that severed the Dawlish rail link, the impacts of Storm Darragh on Holyhead port, the electrical substation fire that forced the closure of Heathrow Airport, periods of extreme summer heat and wider geopolitical instability affecting international travel and supply chains. Collectively, these events demonstrate that disruption no longer comes from a single predictable source. Climate change, cyber threats, infrastructure failures, security incidents and global events all have the potential to affect transport operations simultaneously.

For the ITS community, perhaps the most important aspect of the strategy is its recognition that transport should be viewed as an interconnected system rather than a collection of independent modes. That principle has long been at the heart of ITS thinking. Whether through integrated traffic management, Mobility as a Service platforms, connected vehicle ecosystems or multimodal journey planning, intelligent mobility technologies seek to understand and manage the relationships between different parts of the network.

The DfT's strategy explicitly acknowledges that disruption in one location or sector can quickly create consequences elsewhere. This systems-based perspective strengthens the case for greater investment in integrated data sharing and real-time operational intelligence. In many respects, the strategy reinforces the importance of the digital tools that transport authorities and operators have been developing for years.

One of the strategy’s three core objectives is to continuously assess how resilient the transport sector is, allowing interventions and resources to be targeted more effectively. Achieving that ambition will be difficult without robust data capabilities.

Across the ITS sector, technologies already exist that can contribute directly to this objective. Digital twins, condition monitoring sensors, predictive analytics, connected asset management platforms and AI-driven risk modelling all provide opportunities to identify vulnerabilities before disruption occurs. Rather than simply reacting to incidents, operators can increasingly anticipate problems and intervene earlier.

This reflects a broader shift in thinking around resilience. Traditional approaches often focused on emergency response. The new strategy places much greater emphasis on anticipation, assessment, prevention and preparedness. The document repeatedly highlights the importance of acting before a crisis develops rather than relying solely on effective response once disruption has occurred.

That distinction matters because intelligent transport technologies are generally at their most valuable during the early stages of the resilience cycle. Connected infrastructure can detect faults before they become failures. Traffic management systems can identify developing congestion patterns before they escalate into network-wide disruption. Weather monitoring systems can provide advance warning of risks posed by flooding, high winds or extreme temperatures. Freight visibility platforms can help operators understand the wider consequences of disruption across supply chains.

Climate resilience emerges as another major theme running throughout the strategy. References to storms, extreme heat and rising sea levels underline the growing challenge facing transport infrastructure owners and operators.
