In the context of autonomous driving and advanced simulation, not all road features are created equal. Some elements—like guardrails, safety barriers, and crash attenuators—serve as critical infrastructure that protects lives and influences vehicle behavior in both physical and virtual environments.
At Automotive Artificial Intelligence (AAI) GmbH, we’ve built RepliMap to ensure these safety-critical elements are not just included, but modeled with engineering-grade precision in both ASAM OpenDRIVE and Lanelet2 formats.
More Than Lines: Structuring Safety with Context
Guardrails and barriers are far more than roadside accessories. They define physical boundaries, affect crash dynamics, and directly influence automated path planning. That’s why RepliMap captures each structure with a rich layer of metadata, including:
- Type and classification (e.g., steel guardrail, concrete barrier, wire rope)
- Exact spatial alignment and elevation
- Size and geometry, including height and lateral offset
- Repeat logic and continuity, critical for long stretches like highways or bridge runs
These aren’t decorative annotations—they’re functional data points used across simulation, validation, and deployment pipelines.
What RepliMap Enables
By modeling guardrails and barriers with this level of depth, RepliMap empowers:
✔️ Collision Boundary Definition
Map boundaries that reflect physical limitations, ensuring autonomous systems don’t “drive through” virtual walls.
✔️ Crash Test Simulation
Engineers can simulate impacts with realistic surface types, angles, and rebound behaviors—supporting digital homologation and scenario-based safety assessments.
✔️ AV Path Planning with Realistic Constraints
Whether it’s avoiding a concrete median or calculating a safe overtake, RepliMap provides the real-world spatial logic required for accurate trajectory generation.
Digital Twins Need Real-World Details
The future of testing, planning, and deployment lies in digital twins—virtual representations of physical spaces. But without detailed infrastructure modeling, digital twins are just incomplete sketches. RepliMap ensures that your virtual roads include the barriers that matter most—for safety, regulation, and real-world fidelity.
Standards-Ready, Deployment-Ready
RepliMap’s guardrail and barrier data is fully structured for cross-platform interoperability, with seamless export into:
- ASAM OpenDRIVE: Enabling integration into simulation environments like IPG CarMaker or Vires VTD
- Lanelet2: Supporting autonomous driving stacks and real-time map rendering
Whether you're planning a test site, validating AV behavior, or simulating crash scenarios, RepliMap delivers precision you can rely on.
📌 Coming soon: RepliMap is in pre-release and currently being piloted across AV, simulation, and smart infrastructure projects.
