Integrated V2X Information Trust Performance Model

• Jun 26, 2026

Research Description

Identify an existing or develop a framework for managing trust and sharing information between multiple vehicles and offboard sensors to enable reliable cooperative maneuvering at scale.

What we hope to learn: Identify characteristics of a model or analytical framework where information reliability, availability, and security performance can be tested to determine what cooperative maneuvering is possible. Determine if the possible maneuver can be performed under a safety critical use case and under what level of automation.

Additional Supporting Information

Benefits: Use the model to describe trust in detail as it relates to information utility and appropriate level of accuracy.

Use the model to determine what level of trust is needed for different types of CAV operations.

Answers question such as: Where are such levels of trust needed? Are they needed globally or are they only needed at critical interaction points (such as freeway merge, intersections and approaches to them, highway rail interfaces, Freeway OnRamps, etc)

Some examples are (these are only examples. There should be others): • What are the confidence dynamics (precision, accuracy, trust) of vehicle’s self-location data and external indicator of positions (such as lane markings or data from other vehicles)? • How robustness is defined in a multiple sensor environment to enable cooperative maneuvering a resilient to some level of functional safety failure or low level attacks.
