Transit Entrances
Place the prompt on approaches where curb geometry makes the pedestrian route clear.
A motorbike on a sidewalk can disrupt a pedestrian route. StreamVLM™ lets an operator describe that visible condition and review the matching frame.
The Visible Condition
The condition in scope is a motorbike or scooter moving or standing on a sidewalk, plaza, or other pedestrian-only route. It is a visible scene detail, not a diagnosis, a conclusion about intent, or an automatic decision.
In StreamVLM™, an authorized operator writes a prompt such as “Alert on a motorcycle riding on the sidewalk.” The model evaluates selected live frames against that prompt and sends a match, camera, location, and time into the IREX event workflow for human review.
StreamVLM™ runs on a GPU node in the customer instance. Each prompt has its own confidence threshold, alert cooldown, event type, and camera selection.
This prompt-defined detector can be evaluated alongside the Two-Wheeler Detection trained-module workflow. The two approaches have different frame-rate and operational-fit considerations, so a pilot should establish which is appropriate for the site.

Place the prompt on approaches where curb geometry makes the pedestrian route clear.
Let traffic staff open the live view before treating the route as obstructed.
Record recurring locations so the city can review signs, barriers, or delivery access.
Illustrative Camera Frames
These illustrative frames show the kind of visible condition a prompt can surface. They are not real incidents, deployments, or proof of detection accuracy.
The operator checks whether the route is pedestrian-only and whether the vehicle is moving through it.
A curb and crossing geometry help a reviewer distinguish the sidewalk from the road.
The prompt brings the visible condition to the screen; the operator decides what response is appropriate.
From Prompt to Action
Write a concise prompt for a motorbike or scooter moving or standing on a sidewalk, plaza, or other pedestrian-only route, then select the cameras and times where the condition warrants attention.
Open the event with its camera, location, time, and available video context. Confirm what is visible before treating the match as actionable.
The authorized team applies the local procedure. StreamVLM supplies a review cue; it does not decide the response.
Limits to Test
The prompt can be written for a motorcycle or scooter, but the operator should confirm the vehicle type in the frame. Distance, angle, and an obscured vehicle can make that distinction unreliable.
No. It reports a match to the visible condition in the prompt. An operator reviews the frame and local context before deciding what it means.
Start with representative cameras, define what makes a useful alert, then adjust the camera selection, confidence threshold, and alert cooldown during a camera-specific pilot.
IREX does not publish a universal accuracy figure for this prompt. Image quality, camera angle, lighting, occlusion, and the local definition of a useful alert all affect results.
