AgentDrive: An Open Benchmark Dataset for Agentic AI Reasoning with LLM-Generated Scenarios in Autonomous Systems
Abstract: The rapid advancement of LLMs has sparked growing interest in their integration into autonomous systems for reasoning-driven perception, planning, and decision-making. However, evaluating and training such agentic AI models remains challenging due to the lack of large-scale, structured, and safety-critical benchmarks. This paper introduces AgentDrive, an open benchmark dataset containing 300,000 LLM-generated driving scenarios designed for training, fine-tuning, and evaluating autonomous agents under diverse conditions. AgentDrive formalizes a factorized scenario space across seven orthogonal axes: scenario type, driver behavior, environment, road layout, objective, difficulty, and traffic density. An LLM-driven prompt-to-JSON pipeline generates semantically rich, simulation-ready specifications that are validated against physical and schema constraints. Each scenario undergoes simulation rollouts, surrogate safety metric computation, and rule-based outcome labeling. To complement simulation-based evaluation, we introduce AgentDrive-MCQ, a 100,000-question multiple-choice benchmark spanning five reasoning dimensions: physics, policy, hybrid, scenario, and comparative reasoning. We conduct a large-scale evaluation of fifty leading LLMs on AgentDrive-MCQ. Results show that while proprietary frontier models perform best in contextual and policy reasoning, advanced open models are rapidly closing the gap in structured and physics-grounded reasoning. We release the AgentDrive dataset, AgentDrive-MCQ benchmark, evaluation code, and related materials at https://github.com/maferrag/AgentDrive

AgentDrive: A Benchmark Suite for Agentic Reasoning in Autonomous Driving via LLM-Generated Scenarios
Introduction and Motivation
Autonomous driving (AD) presents complex challenges in perception, planning, and decision-making under diverse, safety-critical scenarios. Recent advances in LLMs have catalyzed renewed interest in applying agentic reasoning paradigms to AD, promising enhanced contextual understanding and reasoning capabilities beyond established feedforward or rule-based approaches. A key bottleneck in the development and evaluation of such agentic AI systems has been the lack of extensible, simulation-grounded, and reasoning-oriented benchmark datasets that enable fine-grained assessment of both cognitive and ethical decision processes.
The AgentDrive benchmark suite directly addresses this gap. It introduces (i) a 300,000-sample corpus of LLM-generated driving scenarios (AgentDrive-Gen), (ii) closed-loop simulation and rule-based outcome labeling (AgentDrive-Sim), and (iii) a reasoning-intensive multiple choice question (MCQ) evaluation bench (AgentDrive-MCQ) with 100,000 MCQs spanning five reasoning dimensions. This comprehensive framework provides a unified methodology for scenario factorization, specification, simulation, labeling, and structured reasoning evaluation, directly supporting large-scale training, fine-tuning, and stringent benchmarking of agentic LLMs in AD.

AgentDrive Framework and Methodology
AgentDrive adopts a factorized approach to scenario space generation, formalizing autonomous driving contexts across seven orthogonal axes: scenario type, driver behavior, environment, road layout, objective, difficulty, and traffic density. This multidimensional formalism supports systematic and entropy-maximized sampling, ensuring broad coverage of routine, rare, and compound edge cases critical for robustness assessment.
Generation proceeds via an LLM-driven prompt engineering pipeline, translating abstract tuples into semantically rich, simulation-ready JSON specifications, strictly validated against schema and physical constraints. Each scenario is executed in simulation (highway-env), with surrogate safety metrics—primarily minimum time-to-collision (TTC)—computed for downstream assessment. Rule-based labeling assigns interpretable categorical outcomes (safe_goal, safe_stop, unsafe, inefficient), facilitating both supervised learning and qualitative analysis.

Dataset properties reveal balanced distribution across difficulty levels and scenario layouts, with explicit encoding of adverse environments, hazardous behaviors, and complex geometries to probe LLM weaknesses in rare, critical conditions.

Reasoning Benchmark: AgentDrive-MCQ
AgentDrive-MCQ extends the simulation dataset into the reasoning domain by synthesizing 100,000 MCQs spanning five reasoning dimensions:
- Physics: Quantitative kinematics and numerical safety estimation
- Policy: Rule-based and regulatory compliance reasoning
- Hybrid: Multi-constraint compositional reasoning (quantitative and symbolic)
- Scenario: Qualitative risk, context, and hazard interpretation
- Comparative: Action selection and safety optimization among competing choices
Each scenario is narratively described, followed by five MCQs. Stringent formatting and answer validation protocols ensure the benchmark’s reproducibility and depth. This construct rigorously tests cognitive breadth—from mathematical estimation to ethical and situational prioritization.

Large-Scale LLM Evaluation: Comparative Analysis
Fifty cutting-edge LLMs, including both proprietary (GPT-5, ChatGPT 4o, Gemini 2.5) and open-source (Qwen3 235B, ERNIE 4.5 300B, Mistral Medium 3.1, Phi 4 Reasoning Plus) models, were evaluated on 2K MCQ samples per model, per reasoning style. Key findings include:
- Frontier proprietary models (ChatGPT 4o, GPT-5 Chat) outperform in contextual and policy reasoning, achieving perfect or near-perfect scores in policy and scenario dimensions.
- Advanced open-source models—notably Qwen3 235B and ERNIE 4.5 300B—substantially narrow the gap in physics and hybrid reasoning.
- Hybrid reasoning remains the most challenging, with all models exhibiting reduced accuracy; the requirement to integrate symbolic and quantitative constraints exposes persistent limitations in cognitive compositionality.
- Scenario-style reasoning yields the highest individual accuracies; top models consistently display robust situational synthesis and hazard awareness.

The results establish a direct link between model architecture scale, fine-tuning strategy, and reasoning performance, underscoring the importance of comprehensive benchmarking for agentic AD systems. The systematic quantification of situational awareness (SAS) and safety compliance (SCR) provides actionable metrics for model selection and risk assessment in deployment contexts.
Implications and Future Directions

A simple explanation of “AgentDrive: An Open Benchmark Dataset for Agentic AI Reasoning with LLM-Generated Scenarios in Autonomous Systems”
What is this paper about?
This paper introduces AgentDrive, a big, open dataset and test suite designed to help build and evaluate smart AI “agents” for self-driving cars. These agents use LLMs—the same kind of AI behind chatbots—to reason about driving, follow rules, and make decisions. AgentDrive creates hundreds of thousands of realistic, varied driving situations (all in simulation) and a huge set of multiple-choice questions about driving. Together, these let researchers train and test how well AI can think, plan, and stay safe on the road.
What questions is the paper trying to answer?
To make the purpose clear, the paper focuses on three main questions:
- How can we use LLMs to automatically generate lots of diverse, realistic, and safety-focused driving scenarios for training and testing AI drivers?
- How can we combine simulated driving data with reasoning questions to evaluate both the practical driving skills and the thinking skills (like physics understanding and ethics) of AI?
- How well do top AI models—both commercial and open-source—perform across different types of driving-related reasoning?
How did the researchers do it?
The researchers built an end-to-end pipeline—think of it like a factory—for creating, checking, and scoring driving scenarios and reasoning questions.
Here’s the process, explained with simple analogies:
- Designing the scenario space: They define seven “sliders” that shape each scenario: the type of situation, how drivers behave, the environment (like rain or fog), the road layout, the ego car’s goal, difficulty level, and traffic density. Moving these sliders creates many different combinations, like mixing ingredients to get new recipes.
- LLM prompt-to-JSON generation: The AI (LLM) is given a structured prompt and asked to output a detailed scenario description in JSON (which is a computer-friendly “recipe card” format). This includes the road, cars, traffic lights, timing, and objectives.
- Schema and physics validation: The JSON is checked against rules (like “no negative speeds” and “traffic light timings make sense”) to make sure everything is consistent and possible in the real world.
- Simulation rollouts: Each scenario is then “played out” in a driving simulator, similar to running a level in a racing game to see what happens over time.
- Safety metrics: They compute surrogate safety metrics—quick-to-calculate numbers that reflect risk. One key metric is Time-To-Collision (TTC), which means “if you keep going as you are, how soon until you’d crash?” Lower TTC means higher danger.
- Outcome labels: Each run gets a simple label based on what happened: unsafe (e.g., a crash or red light violation), safe goal (e.g., stopped at red, then crossed on green), safe stop (stopped safely), or inefficient (safe but slow or unhelpful behavior).
- Reasoning questions (AgentDrive-MCQ): From the scenarios, they also auto-generate 100,000 multiple-choice questions to test an AI’s thinking. These questions cover:
- Physics: motion, distance, speed, safe following, braking
- Policy: traffic laws and ethics (e.g., right of way)
- Scenario: understanding the situation described
- Comparative: choosing the best option out of several
- Hybrid: a mix of physics and policy
In short, AgentDrive is both a virtual test track and a written exam, built at very large scale.
What did they find, and why does it matter?
The paper introduces three main pieces:
- AgentDrive-Gen: 300,000 simulation-ready, LLM-generated driving scenarios across the seven axes (type, driver behavior, environment, road layout, objective, difficulty, traffic density). These are validated and balanced so there are both everyday and rare, safety-critical cases.
- AgentDrive-Sim: The same scenarios, now with simulation rollouts, safety metrics (like TTC), and clear outcome labels. This makes it easy to train AI and measure performance.
- AgentDrive-MCQ: 100,000 reasoning questions that test different kinds of thinking relevant to driving.
They also tested 50 leading LLMs on the reasoning questions. The overall takeaway:
- Frontier commercial models performed best at policy and contextual reasoning (understanding rules and complex situations).
- Advanced open-source models are catching up fast in structured, physics-based reasoning (calculations and safety logic).
- This suggests that the gap is narrowing, especially in areas where precise logic and numbers matter.
Why it’s important:
- Safer self-driving: Better tests mean safer training, especially for rare but dangerous situations.
- Clear benchmarking: A standard, open benchmark helps everyone compare methods fairly and build on each other’s work.
- Balanced evaluation: It checks both “doing” (in simulation) and “thinking” (in reasoning questions), which is crucial for trustworthy autonomy.
What’s the big picture?
AgentDrive provides a unified, open toolkit for developing and evaluating AI that can drive and think safely. It could help:
- Researchers train more reliable self-driving agents with well-structured, diverse scenarios.
- Companies and regulators measure safety and reasoning in a consistent way.
- The community move toward autonomous systems that are not only capable but also ethical and compliant with traffic rules.
The authors note a current limitation: the reasoning part is text-based (no images or sensor data yet). They plan to add multimodal (visual + language) elements in the future, which will bring AgentDrive even closer to real-world driving.
Overall, AgentDrive is like building a huge, smart driving school for AI—complete with realistic practice tracks and challenging written exams—so we can better trust AI to make good choices on the road.
Knowledge Gaps
Knowledge gaps, limitations, and open questions
Below is a single, concrete list of what remains missing, uncertain, or unexplored in the paper, aimed to guide future research.
- Multimodal grounding absent: AgentDrive-MCQ and scenario specifications are text-only; integration of visual, LiDAR, radar, and map modalities (and evaluation of VLMs) within the same pipeline is not implemented.
- Simulator fidelity and transferability: The pipeline relies on highway-env (simplified kinematics and environment); it is unclear how results transfer to higher-fidelity simulators (e.g., CARLA) or real-world driving.
- Physical and legal validation depth: JSON schema checks ensure structure but not deep physical feasibility or traffic-law compliance; automated validators, formal verification, and human audits are not reported.
- Surrogate safety metrics coverage: Evaluation is dominated by TTC with fixed thresholds; lateral risk, PET, DRAC, jerk/comfort, severity, and scenario-specific metrics are missing and thresholds are not calibrated to real-world risk.
- Rule-based labeling reliability: The mapping to unsafe/safe_goal/safe_stop/inefficient may misclassify complex cases and seems objective-specific; no human-in-the-loop validation, inter-rater reliability, or label noise quantification is provided.
- Closed-loop agent evaluation: The benchmark assesses MCQ reasoning but does not evaluate LLM-driven planners/controllers on AgentDrive-Sim in real time (on-policy performance, latency, stability).
- Training efficacy evidence: Although designed for training/fine-tuning, the paper does not demonstrate that AgentDrive materially improves autonomous planning/safety vs. baselines; ablation studies are needed.
- Scenario diversity imbalances: Reported distributions skew toward daytime, good visibility, and clear weather; robust stratified sampling is needed to guarantee adequate coverage of rare adverse and edge conditions.
- Formal coverage measurement: No quantitative coverage metrics over the seven axes or their interactions are reported; rare-event density and compositional coverage remain unmeasured.
- LLM generation provenance and bias control: The specific LLMs, hyperparameters (temperature, decoding), seeds, and quality-control procedures used to generate the 300k scenarios are not detailed; bias/hallucination detection and repair remain unclear.
- MCQ validity and reliability: The 100k questions lack psychometric analysis (difficulty, discrimination), ambiguity checks, human verification rates, and adversarial option design; correctness and reliability need auditing.
- Policy/regulatory scope: “Policy” reasoning may be jurisdiction-specific; coverage across regions, updates to evolving laws, and explicit region tagging or retrieval of local statutes are not described.
- Environmental degradation modeling: Textual weather/visibility do not translate into sensor/perception degradation in highway-env; robust modeling of sensing failures and noise is absent.
- VRU realism: While VRUs are in the taxonomy, realistic pedestrian/cyclist dynamics, occlusions, and interactions (e.g., at crosswalks) appear limited by the simulator; dedicated VRU scenarios and models are needed.
- Efficiency metric definition: The “inefficient” label lacks explicit quantitative criteria (delay, stop count, fuel/energy, comfort); standardized efficiency metrics and thresholds are not defined.
- Orthogonality assumption: Scenario axes are treated as independent, but real-world dependencies (e.g., aggressive behavior in congestion) are not modeled; learning joint distributions from naturalistic data is open.
- Reproducibility of LLM evaluations: Testing 50 LLMs may be sensitive to prompt wording, temperatures, context lengths, and seeds; locked evaluation protocols and statistical significance reporting are missing.
- Contamination/leakage risk: Possible training-data overlap between LLMs and AgentDrive-MCQ is not analyzed; leakage detection and mitigation are needed to ensure fair benchmarking.
- Hardware-in-the-loop/real-vehicle validation: No HIL or limited on-road experiments are presented to validate that benchmark gains translate to safer real-world behavior.
- Long-horizon sequential reasoning: MCQs are single-turn; tasks requiring multi-step planning, memory, and plan revision (e.g., dynamic route changes) are not evaluated.
- Adversarial robustness: Scenarios do not include adversarial agents, sensor attacks, map errors, or perception spoofing; adversarial scenario generation and robustness testing are absent.
- Dataset governance and updates: Versioning, curation processes, error correction, and mechanisms to add new axes or retire flawed items are not documented; continuous dataset integration is an open need.
- Compute and sustainability: The resource/energy footprint for generating, simulating, and evaluating at this scale is not reported; efficiency baselines and lightweight subsets are needed.
- Cross-simulator standardization: The JSON schema is tailored to highway-env; portability and conformance across CARLA, LGSVL, Webots, and other simulators are not demonstrated.
- Reasoning-to-driving correlation: The paper reports MCQ scores but does not show whether higher reasoning performance predicts safer or more efficient behavior in simulation or real driving; correlation studies are missing.
