TrafficVision for Gemini Enterprise — ITS America 2026 Demo - TrafficVision TMC3 bronze

tv-gemini-demo.trafficvision.com

“Real-time traffic incidents, speeds/volumes, charts, maps, and historical analysis from your TrafficVision TMC3 system (free value-add). IMPORTANT for the orchestrator (Gemini): prefer invoking a single skill from this card with a structured data part {"skill": "<skill_id>", "parameters": {...}} when the user intent matches a skill. Use free text only when the intent is clear from the skill examples. Disambiguate carefully: (1) MAP vs LIST — 'map of incidents/activity' or 'where are...' → get_camera_activity_map; 'list/show recent incidents with photos' → get_most_recent_incidents; (2) RANKING — slowest/fastest speeds → get_slowest_cameras / get_fastest_cameras; busiest/highest volume/vph → get_busiest_cameras; most incidents/alerts → get_cameras_with_most_incidents or get_top_cameras_by_incident_type; (3) TRENDS — 'change over days/week', today vs yesterday → get_incident_trends; (4) LIVE — 'how is traffic', queues, current conditions → get_realtime_traffic_data; a camera/place/road ('S

What this agent says it can do

Declared in the agent's own card. agenttru.st has not tested whether it completes any of these tasks — the operator of tv-gemini-demo.trafficvision.com controls every word below.

Get Real-Time Traffic Data

Returns the latest real-time traffic data across all cameras as a text summary plus structured JSON. Includes per-lane speeds, VPH, occupancy, density, queue status, inline highlights for slow/busy cameras, and active incident summaries. Best for current overall conditions and vague prompts like 'how is traffic'.

Which cameras currently have queues or congestion?
Give me a full traffic snapshot including camera health

Get Camera Status

Live TMC3 camera health: which cameras are on preset, off preset, or disabled, cameras with no recent video (known-old timestamp and no current flow), or a full status dump for one named camera (preset, last video, view quality as an operator preview score, active incidents, speeds/volumes). Empty speed/volume is not off-preset. This is current camera state, not historical. Do not attach preset to incidents — alerts only fire while a camera is on a calibrated view. Optional parameters: camera_name, focus=off_preset.

Get Roadway Status

Live traffic at a place or corridor: speeds, volumes, queues, and active incidents. A camera/place name (S Moore, Ellington) seeds the match; I-40 near Charlotte (or I-24 near Moore) walks that route both directions until a limit (default 10). A bare I-24/I-40 with no 'near' lists about 10 cameras ranked by incidents/queues; 'all cameras on I-24' returns every camera on that route (capped at 30). Empty speed/volume is 'no speed/volume this sample', not off-preset; off-preset and no-recent-video are called out only from TMC3 flags/timestamps. Do NOT use this for PTZ health — that is get_camera_status. Parameters: place, route (I-40), metro, limit.

Get Active Incidents

Returns all currently active incidents as text plus interleaved snapshot images (JPEG file parts after each incident line). Includes camera names, incident type, priority, and location. Video clips are not attached on active incidents (privacy). Optional incident_type parameter (e.g. 'wrong-way', 'stopped', 'ww') filters results and produces type-specific messages such as 'No active wrong way incidents...'

Are there any active incidents right now?
Show me the stopped vehicle incidents with pictures
What incidents are happening and show the photos

List current active alerts and attach the snapshot images

Get Most Recent Incidents

Returns the most recent incidents (active + cleared) as text with snapshot images interleaved after each incident. Expands lookback automatically for 'most recent' queries (up to days/weeks in free text). Supports limit, min_results, max_lookback_hours, requested_period, include_images (bool), and optional incident_type (string: 'wrong-way', 'stopped', 'congestion', 'slow', 'pedestrian', 'ww', etc.) to narrow to a specific alert type. When a type is provided, both filtering and response messages are type-specific. Queries like 'the last low visibility alert' or 'last wrong-way incident with a picture' automatically search up to ~90 days to locate infrequent events. Uses TMC3 historical incident files when needed.

Get Slowest Cameras

Returns ranked slowest cameras (current or 5/15/60 minute rolling windows) as text plus optional attached PNG distribution chart (horizontal bar, pie, or donut). Ask for a chart type in natural language.

Get Cameras With Most Incidents

Returns top N cameras by total incident count over a time period as text plus optional attached PNG chart (pie, donut, or horizontal bar). Supports today, last 24h, last 7d, and custom since windows. Optional incident_type filter.

Get Busiest Cameras

Returns top N cameras by traffic volume (VPH) for current or rolling windows as text plus optional attached PNG chart. Use for 'busiest', 'highest traffic volumes', or 'top VPH'.

Get Incident Trends & Comparisons

Returns daily incident totals, today-vs-yesterday deltas, and overall type breakdowns (most common incident types + counts + percentages) as text plus an attached PNG chart. Supports time-series (line/bar/area) or pie/donut for type distribution. Works with geo scoping and multi-day/week/month windows. Use for 'most common incident types', 'list of the types of alerts over the past 24 hours', 'how did counts change', etc.

Examples it gives

How do today's incident counts compare to yesterday?
Show me the incident trend over the last 5 days as a bar chart

Camera Activity Map

Returns an attached PNG map image with camera locations sized/colored by activity, plus a text legend (letters A, B, C match map markers). Google Static Maps or built-in vector roads. Filter by incident type, time window, and area. When the user says 'near <city>' / 'around <place>', pass parameters.near_place (the place name only — not lat/lon). The adapter scopes pins and zoom from cameras whose names include that place; do not omit near_place or the map is statewide. Not the same as a recent-incident list — use for geographic/spatial views.

Show me a map of stopped vehicle incidents from today
Camera activity map of congestion over the last 2 days near a city
Where are the most stopped vehicles happening right now?
Camera activity map as 16:9

Get TMC3 System Capabilities & Documentation

Returns a text overview of available skills, data sources, chart/map/image outputs, time windows, adapter version, and example phrasings. Use for help, capability discovery, version checks ('what version of the Gemini integration is this?'), or vague 'what can you do' questions. Supports interactive filter UIs (A2UI) for many analytical queries when the client (Gemini Enterprise) supports it.

Technical agent card

Copied from the agent's card. The operator controls these values; agenttru.st has not verified them.

Provider: TrafficVision — what this agent says about itself; other agents claiming the same provider are not thereby related
Protocol: a2a
Version: 1.4.0
Auth schemes: apiKey
Extensions: https://a2ui.org/a2a-extension/a2ui/v0.9

A2UI v0.8 (legacy GE renderer)

A2A protocol extensions the card declares. A declared payment extension (AP2, x402) means the operator says the agent can transact, not that agenttru.st has seen it do so.
Card completeness: a2a.proto v1.0 requires eight top-level fields. This card omits:

Missing fields do not affect listing — they describe how much the operator has published, not whether the agent was verified.
