Agentic Traffic Market

An experimental system that clears intersections by market instead of traffic light. Each vehicle's AI agent negotiates for right of way, weighing urgency and its funds, and settles with a micropayment. Small instant payments run without handing over keys, sketching traffic as it might look once driving is autonomous.

From the organizer's citation (summary)

Judges called replacing a traffic light with a market mechanism a novel idea and an interesting attempt to apply agents to mobility. They found reason in how agreements are designed to form, and credited the technical implementation as well.

Why It Won — our reading

An encouragement award tends to reward the question more than immediate usefulness. A traffic light halts everyone and hands out turns; this project swaps in a different principle, whoever is in a hurry pays for priority. What lifts it above a thought experiment is that negotiation does not end in words but runs through to settlement, so an agreement actually closes. Deployment would need social consent long before engineering, but that was presumably not the axis here.

This is our own analysis based on the official announcement and the project's own materials. It is not the organizer's stated reasoning.

2026A
Grand Prize

Anatom-AI

第4回 Agentic AI Hackathon with Google Cloud
A 3D anatomy atlas driven by plain language. Ask about cerebral infarction and the AI picks the relevant organs and vessels, renders them in 3D and adds an explanation. Interpretation, identification and drawing are separate stages, holding down wrong displays, and ambiguous input comes back as candidates to confirm.
2026B
Award of Excellence

Bananacraft

第4回 Agentic AI Hackathon with Google Cloud
An agent that builds a Minecraft town from a vague description. It draws a concept image, works out zoning and building plans, then converts the image in two steps, putting the structure into language before turning it into coordinates, which keeps the result coherent. The frame goes up in bulk; a bot adds decoration on site.
2026B
Award of Excellence

BrickQuest

第4回 Agentic AI Hackathon with Google Cloud
An app that suggests what you can build with the bricks you own. It recognises parts from photos to build an inventory, and once you pick a theme and difficulty the AI generates a 3D build sequence. A physics engine checks it for overlaps and floating pieces, reports the faults and makes the AI redo it, up to three times.
2026K
Excellence Award

KOTOWARI Link

第4回 Agentic AI Hackathon with Google Cloud
An app that lays the laws behind everyday scenes over the scenes themselves in AR. Pick a difficulty and a field, point a phone at a fountain or a bridge, and an AI reads the image and draws trajectories and force vectors on top of what the camera sees. If curiosity goes further, a link leads to a fuller written explanation.
