Case studies

Our innovation case studies demonstrate the real-world impact of our work, showcasing how each initiative addresses specific business challenges and delivers measurable outcomes. They bring innovation to life while highlighting key insights, best practices and lessons learned that others could draw on and apply in their own organisations.

We align our projects with the following themes:

Safety
Decarbonisation

RIS2 case studies

For older case studies from 2020-25, please visit the RIS2 case study archive.

Safety

Innovations that enable our ambition that no one is harmed while travelling or working on our roads

Diverging diamond interchanges

Improving junction safety and performance by assessing the use of diverging diamond interchanges on the Strategic Road Network, evaluating benefits, risks and implications for UK design standards.

Climate grassland retrofit

Reducing soft-estate maintenance by trialling low-nutrient substrates such as crushed chalk that slow vegetation growth and improve safety and biodiversity.

Structures moonshot

Improving safety and confidence in the condition of ageing structures by providing insight into hidden components using existing and emerging technologies.

Influencing uptake of in-vehicle safety technologies

Improving our understanding of in-vehicle safety technology adoption and how these trends influence killed or seriously injured causalities on the strategic road network.

Addressing gaps in understanding of KSI impacts

Improving understanding of whether longitudinal road markings and junction treatments affect driver behaviour and help reduce people killed or seriously injured (KSI) on A-roads.

Decarbonisation

Innovations that enable our ambition to achieve net zero across our roads and operations

Future asphalt surface course

Advancing the use of low-carbon asphalt by building confidence in new materials through coordinated trials, testing and structured evaluation of their performance.

Decarbonising concrete

Enabling the use of lower-carbon concretes by building evidence on lower-carbon cement blends to support future inclusion in industry standards.
