Following the unveiling of RoadTrace’s now globally proven ITS technical white paper on KSI prediction at NRSC 2024, Thierry Castermans returns to share how the science has evolved into real-world action. With dozens of UK and international highway authorities now using RoadTrace to proactively identify high-risk locations before collisions occur, this session will highlight practical, data-driven quick wins already delivering impact on the ground.

Built on connected vehicle data, RoadTrace models driver behaviour at scale – especially harsh braking events as a lead safety indicator – to reveal emerging risks invisible in crash records alone. These behavioural clusters are proving to be highly valuable to RoadTrace clients, and Thierry will demonstrate how this insight is supporting better decision-making across casualty reduction, investment prioritisation and scheme evaluation.

This presentation will show how highways authorities are embedding RoadTrace insights into their Safe System planning, aligning infrastructure risk with Vision Zero goals and strengthening the evidence base for funding and intervention. As the technology continues to expand, the session will also explore how RoadTrace is shaping the future of in-vehicle safety — working with our automotive partners to bring RoadTrace road safety data directly into the vehicle and connect drivers with infrastructure-level intelligence.

 Attendees will gain a clear understanding of how connected vehicle data can be used not just to analyse risk, but to anticipate and prevent it. Where possible, we’d also welcome a local authority client to co-present a live case study, demonstrating how this approach has been applied in practice to support road safety and asset management outcomes.
