Driver Monitoring for a Driver-Centered Design and Assessment of a Merging Assistance System Based on V2V...

Area of Science:

• Road transport safety
• Human-computer interaction
• Cognitive load in driving

Background:

• Merging on highways is a critical maneuver with high driver cognitive load.
• Previous research used eye tracking to study merging's impact on mental workload.
• This established the need for a driver assistance system for highway merging.

Purpose of the Study:

• To develop and evaluate a novel merging assistance system using vehicle-to-vehicle (V2V) communication.
• To reduce driver mental load and improve safety during highway merging.
• To assess the system's usability and effectiveness in real-world driving scenarios.

Main Methods:

• Implementation of a V2V communication system on a mobile device for data sharing (position, speed).
• Development of an algorithm to determine safe merging conditions and provide driver information.
• Interface design refined through driving simulator tests for minimal intrusiveness.
• Real-world testing with drivers in a passenger car to evaluate usability and mental load.

Main Results:

• The V2V merging assistance system effectively shares vehicle data to inform merging decisions.
• Driver interface was optimized through simulation to be less demanding.
• Real-world tests demonstrated the system's usability and potential to reduce mental load.
• Effectiveness was assessed through comparisons with alternative solutions.

Conclusions:

• The developed V2V merging assistance system offers a promising approach to enhance highway merging safety.
• Reducing cognitive load through intelligent driver support is crucial for critical driving maneuvers.
• The system's real-world validation confirms its practical applicability and effectiveness.
