# Impact assessment methodology for connected and automated vehicles

## TL;DR

This paper introduces a structured methodology to assess the societal impacts of connected and automated vehicles, using feedback loops and expert input.

## Contribution

The novelty lies in the structured approach that incorporates feedback loops and combines literature review with expert interviews for impact assessment.

## Key findings

- The methodology was developed and applied in the LEVITATE project.
- Feedback loops between impacts are considered early in the assessment process.
- Further steps for quantitative impact evaluation are outlined.

## Abstract

Connected and automated vehicles have become more common in recent years, increasing the need to assess their societal level impacts. In this paper a methodology is presented to explore and define these impacts as a starting point for quantitative impact assessment. The many interrelations between impacts increases the complexity of obtaining a complete overview. Therefore, a structured approach is used, which shows many similarities with the modelling of causal-loop-diagrams. Feedback loops between impacts are taken into account at an early stage and both literature review and expert interviews are used to produce a holistic overview of impacts. The methodology was developed and applied in the European H2020 project LEVITATE. Results from the qualitative assessments in this project are presented and further steps needed to perform a quantitative evaluation of the impacts are discussed.
