After you! Design and evaluation of a human machine interface for cooperative truck overtaking maneuvers on freeways

Truck overtaking maneuvers on freeways are inefficient, risky and promote high potential for conflict between road users. Collective perception based on V2X communication allow coordination with all parties to reduce the negative impact and could be installed in a timely manner compared to automation. However, the prerequisite for the success of this system is a human-machine interface that the driver can easily operate, trusts and accepts. In this approach, a user-centered conception and design of a human-machine interface for cooperative truck overtaking maneuver on freeways is presented. The development process is separated in two steps: After a prototype is build based on task analysis it is initially evaluated and improved iteratively with a heuristic evaluation by experts. The final prototype is tested in a simulator study with 30 truck drivers. The study provides initial feedback regarding the drivers' attitudes towards such a system and how it can be further improved.
