The West-of-England-based FLOURISH driverless car research and development project has today released its mid-project trials report detailing its latest findings and what they mean for the future deployment of connected and autonomous vehicles (CAVs) on the UK road network.
The University of Bristol's Professor Robert Piechocki said: "We are on the cusp of the biggest revolution on our roads since the advent of the internal combustion engine. Connected and Automated Vehicles (CAV) promise to deliver safe, efficient, inclusive and environmentally responsible transportation services. However future smart vehicles will require smart infrastructure to fulfil all the promised potentials. Roadside sensing (via lidar, radar, video etc.) will enhance road safety; virtual and dynamic signage and regulations communicated wirelessly will orchestrate traffic flow and resolve contention at intersections. The Flourish project attempts to provide the first glimpse of that future."

Tracey Poole, FLOURISH Project Manager, said: "Our trials explore what older adults need to be able to interact with CAVs with confidence. At a technical level, FLOURISH supports this aspiration by investigating how data can be used to optimise regional transport networks and how to ensure secure communications between autonomous vehicles and the surrounding transport infrastructure."
The early findings from this user research suggest that older adults prefer to use an uncluttered and highly intuitive Human-Machine Interface (HMI) to interact with CAVs. The results also indicate that trial participants' trust in the CAV is optimised when they have the option of receiving journey management information from the vehicle in both an audio and visual form. These findings will help inform future HMI designs.
Project - Investigations - Dependability - Communications - Message
Furthermore, the project's investigations into the dependability of communications and message handling between autonomous vehicles and roadside assets have spanned signal coverage, reliability of transmission and cyber responsiveness.
Under the trial conditions, the maximum distance for the successful communication of messages was 472 metres, with...
