# MobilityBench: A Benchmark for Evaluating Route-Planning Agents in Real-World Mobility Scenarios

[Paper](https://huggingface.co/papers/2602.22638) | [GitHub](https://github.com/AMAP-ML/MobilityBench)

**MobilityBench** is a scalable benchmark for evaluating route-planning agents in real-world mobility scenarios. It is built from large-scale, anonymized mobility queries from **Amap**, organized with a comprehensive task taxonomy, and provides **structured ground truth** (required tool calls + verifiable evidence). All tool calls are executed in a **deterministic replay sandbox** for reproducible, multi-dimensional evaluation.

**Scale & Coverage:** 100,000 episodes across **22** countries and **350+** cities (including metropolitan areas), with a **long-tailed** geographic distribution.

### Scenario Distribution (11 intents)
- **36.6%** Basic Information Retrieval
- **9.6%** Route-Dependent Information Retrieval
- **42.5%** Basic Route Planning
- **11.3%** Preference-Constrained Route Planning

#### Data Format

| Field | Description |
|-------|-------------|
| `query` | User query text |
| `context` | Context information (JSON, e.g., current location, city) |
| `task_scenario` | Fine-grained task category |
| `intent_family` | Coarse-grained intent category for evaluation aggregation |
| `tool_list` | Expected tool calls (JSON array) |
| `route_ans` | Ground truth route answer (JSON) |

#### Sample Data (5 Examples)

| Query | Task Scenario | Intent Family |
|-------|---------------|---------------|
| 去大石桥不走高速<br>Go to Dashiqiao without taking the highway. | Option-Constrained Route Planning | Preference-Constrained Route Planning |
| 现在成都大道会堵车吗？看一下地图，会不会堵<br>Is Chengdu Avenue congested now? Looking at the map, is it likely to be congested? | Traffic Info Query | Basic Route Planning |
| 我在哪<br>Where am I? | Geolocation Query | Basic Information Retrieval |
| 知道离滇池会展中心有多远<br>How far it is from Dianchi Convention and Exhibition Center? | Route Property Query | Route-Dependent Information Retrieval |
| 到寨河收费站入口不走高速<br>To reach the Zhaihe toll station entrance without taking the highway. | Option-Constrained Route Planning | Preference-Constrained Route Planning |
