Solution Approach 1:

The system performs baseline performance measurements before software modifications are implemented. By establishing pre-modification performance metrics through standardized test track evaluations, the system creates a reference point that enables objective comparison and assessment of software modification impacts

Inventive Principle:

AI summary

The present disclosure provides systems and methods to test an autonomous vehicle. In particular, the systems and methods of the present disclosure can receive, from one or more test nodes of a preconfigured test track, log data indicating positions of elements of the test track over a period of time. Log data indicating parameters of an autonomous vehicle over the period of time can be received from the autonomous vehicle. The log data indicating the positions of the elements of the test track over the period of time can be compared with the log data indicating the parameters of the autonomous vehicle over the period of time to determine a performance metric of the autonomous vehicle on the test track over the period of time.
