Test AI driving in stages: define exactly what the system is meant to do and where it is meant to do it, exercise it across varied scenarios in simulation, measure its decisions as well as outcomes, and validate those measurements against physical systems before moving to vehicle trials. Simulation can expose risks; by itself, it cannot establish that a driving system is safe on real roads.
1. Define the feature and where it is allowed to operate
Start with a specific automated driving feature—not a vague goal such as “drive safely.” Write down the feature’s intended behavior, its operational design domain (ODD), and the conditions it is expected to handle. The ODD should make clear the relevant limits, such as the kinds of roads, environmental conditions, and traffic situations in scope.
For example, a test plan for a lane-keeping feature should specify the lane-following behavior being evaluated and the road and visibility conditions in which that behavior is expected. It should also identify what counts as a deviation or other safety-relevant result. NIST’s September 2024 report, Performance Metrics and Test Methods for Automated Driving Systems (NIST IR 8534), recommends structured feature descriptions, behavior specifications, metrics, and scenario-based assessment.
Turn the expected behavior into testable questions
- What action should the system take in each scenario?
- What observable measures will show whether it took that action and what followed?
- Which conditions are inside the feature’s intended operating domain, and which are deliberately outside it?
- What result would trigger a review, a change to the system, or a decision not to advance to the next test stage?
Set the measures and review criteria before running the tests. The sources cited here do not establish a universal numeric pass threshold for AI driving, so do not treat one metric or a single successful run as a general safety certificate.

2. Build the test in simulation first
A controlled simulator lets a team repeat a scenario and vary environmental or traffic conditions without immediately exposing people or vehicles to those conditions on a road. NIST IR 8534 describes high-fidelity, physics-based simulation as a way to generate measurement data and identify potential risks and edge cases before real-world testing.
A typical simulation setup has a physics-based simulation engine, tools to manage scenarios and traffic, and communications middleware. Specialized simulators can be added when the test needs to model another system, such as network communications. NIST IR 8534 lists examples including CARLA, AWSIM, CarSim, Scenario Runner, Eclipse SUMO, ROS 2, ns-3, and OMNeT++; these are examples, not a required software stack.

Test interactions, not just isolated parts
A component test can help identify whether an individual element behaves as expected. A full-system test examines how sensing, decision-making, vehicle control, and other connected systems interact. NIST IR 8527 (June 2024) describes an example systems-interaction testbed combining CARLA for driving scenarios and environments, Autoware for automated driving functions, ROS for messaging, and ns-3 for vehicle-to-everything (V2X) communications. That architecture is one example, not a prescription for every project.
3. Vary scenarios and track what the test covers
Do not rely on a small set of familiar or ideal conditions. Automated systems face a large input space, and NIST’s Autonomous Systems Assurance work explains why test-environment coverage needs to be measured. Build a scenario set that varies relevant inputs—for example, lighting, rain or fog, pedestrians, animals, other vehicles, road markings, and signs—according to the feature’s ODD and the risks being examined.
Rank #3
Record which combinations have been tested and which remain unrepresented. A broad list of scenarios is not proof that the system will handle every real-world situation; the purpose is to make the tested space visible and to find important gaps or systematic weaknesses.
4. Measure decisions, not only crashes
A crash/no-crash result is too blunt to explain whether the system made a good choice. NIST’s Measurement Science for Automated Vehicles project describes methods that include surrogate safety measures such as time-to-collision, forward simulation to estimate outcomes, and comparisons between the system’s actions and counterfactual baselines. Looking across scenarios can reveal repeated weaknesses that a single outcome would miss.

NIST summarizes the goal this way: “Current evaluation methods only answer ‘did a crash happen?’ This project’s products answer the harder question: ‘Did the decision-making system make the best available choice?’” The project describes measurement methods under development; they are not a universal certification standard or a single pass/fail rule.
5. Validate the simulation before relying on it
Before using simulation results to support conclusions about a physical vehicle, check whether the simulated conditions and derived measures correspond meaningfully to physical systems. Compare relevant simulated behavior with physical-system observations and investigate discrepancies. NIST’s measurement project specifically describes validating whether simulation-derived metrics are meaningful on physical systems.

Use those findings to assess the limits of the simulator and the conclusions it can support. If the model does not represent an important sensor, vehicle behavior, or interaction adequately, a favorable simulation result cannot fill that evidence gap.

NHTSA’s framework for automated driving system (ADS) test cases and scenarios spans modeling, simulation, track testing, and open-road testing. Treat each stage as a separate evidence-building step rather than assuming that passing one automatically authorizes the next.
| Stage | What it helps assess | What to establish before advancing |
|---|---|---|
| Modeling | Whether the feature and its expected behavior are represented clearly enough to test. | A documented feature, ODD, behavior specification, and relevant measures. |
| Simulation | Repeatable performance across controlled scenarios and varied conditions. | Scenario coverage, recorded outcomes, and a review of weaknesses; simulation results alone do not establish real-world safety. |
| Track testing | Behavior in a physical test setting under controlled conditions. | Evidence that the planned physical tests are appropriate for the system and setting. The exact requirements depend on the project and jurisdiction. |
| Open-road testing | Behavior in real traffic and road conditions. | Applicable legal and site requirements and a safety basis for the specific deployment conditions. |
The table describes the framework’s stages, not a universal approval checklist. The evidence needed to move between them depends on the vehicle, feature, test site, and jurisdiction.
7. Treat vehicle trials as a separate safety and regulatory step
NHTSA’s Automated Vehicle Safety overview says current automated-vehicle testing and deployment take place in limited, restricted, and designated locations and conditions, and describes NHTSA monitoring safety through its Standing General Order. These high-level statements do not specify every permit, staffing, emergency-response, or site-control requirement for a particular test.
Before a physical trial, identify the applicable rules and site requirements for the project’s vehicle and jurisdiction. Do not infer that a simulator, a track result, or another project’s test procedure satisfies those requirements.
