DATA & RESEARCH

Start with geography.
Validate the behaviour.

This prototype uses a real OSM extract. It includes a saved CCTV sample and a provisional vehicle-mix preset, not a live traffic connection or downloaded city mesh.

What is in this scene?

3D model candidates

Saigon 3D City · HCMC 2025 ↗Free download listing · CC Attribution. Central-city coverage; exact corridor fidelity still needs inspection.HCMC 100 km · commercial GIS model ↗Multiple mesh formats. Vendor describes 2022 GIS data and some AI-generated buildings. Accuracy not independently verified.OSM2World ↗Open-source OSM-to-3D generation with glTF / GLB / OBJ export. Useful for a reproducible base scene.

CCTV observations

Eight snapshots were captured through oracle; seven are unique. The nearest camera looks into the corridor. Goods vehicles are now represented, and a lower bicycle-share prior is available. Exact demand, speed, gaps and signal cycles were not measured. View frames, timestamps and parameter rationale ↗

Next: traffic calibration

Use local video to measure vehicle mix, entry flows, speeds, lateral gaps and queues. SUMO’s sublane model is a candidate for the simulation backend. This viewer currently runs its own simplified model.
