| [sumo-user] Sharing the OpenCity Challenge call with SUMO users |
Dear SUMO Community,
We would like to share the OpenCity Challenge, a transportation track of the IEEE Big Data Cup 2026. Registration is now open on Codabench, and Phase 1 closes on November 6, 2026 (23:59 UTC).
OpenCity invites teams to build a city transport model from open data, covering zones, origin–destination demand, route flows, link flows, and travel times. Origin–destination, route, and link flows must be consistent, and another team must be able to rerun the model and verify each key result.
Participants may use any modeling approach, including classical transport models, machine learning, graph neural networks, or hybrid methods. A Starter Kit with a Tempe tutorial and a validation tool is provided. Students, researchers, developers, and early-career professionals are welcome to participate.
OpenCity is organized by the Shenzhen Urban Transport Planning Center (SUTPC), a Gold Partner of IEEE BigData 2026 (Phoenix, December 14–17, 2026). It is supported by the IEEE ITS Society Technical Committee on Travel Information and Traffic Management.
Important Dates:
Phase 1 deadline: November 6, 2026 (23:59 UTC)
Finalist reproduction materials: November 27, 2026
Results presentation: IEEE BigData 2026, Phoenix, December 14–17, 2026
