The Effects of ADAS on Driving Behavior: A Case Study.

Area of Science:

• * Automotive Engineering
• * Human-Computer Interaction
• * Road Safety

Background:

• * Modern vehicles are equipped with numerous sensors, facilitating the development of advanced driver-assistance systems (ADAS).
• * The effectiveness of ADAS is highly dependent on the specific environmental and road context.
• * Quantifying the real-world utility of in-vehicle warnings is crucial for their practical implementation.

Purpose of the Study:

• * To propose and validate a procedure for quantifying the effectiveness of On-Board Unit (OBU) warnings within a specific road context.
• * To assess the impact of OBU-provided information on driver performance and safety metrics.
• * To evaluate the OBU's utility in a simulated driving environment with young drivers.

Main Methods:

• * Experimentation conducted using a driving simulator with a homogeneous sample of young drivers.
• * Data collected under two conditions: traditional driving (no instrumental support) and driving with an OBU.
• * Analysis of collected data using Analysis of Variance (ANOVA) to identify significant differences.

Main Results:

• * The On-Board Unit (OBU) successfully delivered relevant information to drivers on the investigated road.
• * Driver performance, measured by longitudinal/transverse acceleration, speed, and steering angle, was not negatively impacted by the OBU.
• * The OBU demonstrated its advantage in providing useful information without compromising driving safety parameters.

Conclusions:

• * The OBU is effective in enhancing driver information delivery on specific road segments without degrading performance.
• * Findings suggest that OBU systems can be valuable tools for improving road safety.
• * Infrastructure managers can leverage these findings to implement targeted safety enhancements based on road usage and OBU effectiveness.
