OBJECTIVES

To develop test approaches to evaluate the safety of Automated Vehicles (AVs) that reduces the test duration from a few months to a few days without sacrificing accuracy, and to identify possible failure modes on perception errors and misoperations in how to respond.

APPROACH

Tests are developed in two layers:  scenarios and variations.  Test scenarios are extracted from naturalistic driving data, crash data and expert knowledge.  For each scenario, test variations are developed based on naturalistic driving data collected in the Connected Ann Arbor project.  Statistical tools will be developed, based on the Importance Sampling approach, to measure safety impacts efficiently by reducing the safe and boring events while emphasizing the safety-critical conditions.

OUTCOMES

The findings in this project provide an approach to evaluate the safety level of an automated vehicle

  • We adopted the GMM as a statistical representation of the uncertainty in the naturalistic driving environment
  • We developed new methods for accelerating the test procedure of AVs. The new methods integrate novel techniques in statistical learning, optimization, experimental design, ect.
  • The proposed methods have potential to largely improve the efficiency of an AV safety evaluation procedure
