Transport Performance & Risk Analysis Framework
Welcome to the DARe Handbook
The DARe Handbook provides practical guidance on how to apply and operationalise DARe's Transport Performance & Risk Analysis Framework (TPRAF) and its supporting resources. It follows the first TPRAF Report, produced in early 2026, which explains the purpose, structure, and intended use of the framework.
One framework, two parts
What is the TPRAF?
The Transport Performance & Risk Analysis Framework (TPRAF) is DARe's framework for bringing decarbonisation, climate resilience and adaptation into transport infrastructure decisions. It treats them as part of the same decision, rather than as separate assessments added at the end.
Decision Support Process
The decision-making structure. It guides how problems are identified, risks assessed, interventions developed and options evaluated.
Integrated Modelling Platform
The analytical capability. It combines models and datasets to simulate climate hazards such as floods and heatwaves, measure their impact on transport systems and the people who use them, and test what alternative decisions would achieve.
Better together
The DSP sets out the questions that need answering, and the IMP provides the evidence to answer them. Each can be used on its own, but the greatest value comes from using them together, so that decisions are informed by quantified evidence rather than assumptions alone.
Decision Support Process Handbook
How to frame a problem, assess options and reach an evidenced decision, supported by seven technical modules.

The IMP combines models and datasets to simulate climate-related disruptions to transport infrastructure and users and explores adaptation options to increase resilience and reduce the risk.”

Who is this Handbook for?
The Handbook has been developed for organisations and professionals involved in transport planning, infrastructure management, climate adaptation, resilience, and investment decision-making, including:
- Transport Policymakers
- National Infrastructure Owners
- Local & Combined Authorities
- Transport Operators and Freight Companies
- Engineering and Consultancy Firms
- Academia and Research Organisations
02
What will the Handbook help you do?
The Handbook helps users understand how to apply the TPRAF within their own organisational context. It provides practical guidance on integrating relevant TPRAF components into existing policies, processes, and decision-making activities to support more resilient, adaptable, sustainable, and evidence-based transport infrastructure planning and management.
We set out to create something that bridges the gap between academia and practice. And the TPRAF is the result of extraordinary hard work from our team, who have dedicated themselves to building a resource that is robust and rigorously thought through.
03
Use what you need
The TPRAF has been intentionally designed to be modular and flexible. Users are not expected to apply every element of the framework.
Together or standalone
The Decision Support Process (DSP) and Integrated Modelling Platform (IMP) can be used together as an integrated framework, or independently as standalone approaches.
Element by element
Users can also utilise individual elements of the DSP and IMP where they add the greatest value, or combine specific DSP and IMP elements to meet particular decision-making needs, without implementing the DSP, IMP or the integrated TPRAF in its entirety.
04
A living resource
This Handbook is currently a work in progress. Content will continue to be expanded and refined as the TPRAF is tested through DARe case studies and stakeholder engagement activities.
2027
The Hub is also developing additional guidance resources, to compliment the Handbook, which will be made available before the end of March 2027.
