# Edge AI for smart cities and traffic

City and roadside cameras that do more than record: they monitor traffic, detect violations, warn of floods and spot infrastructure problems, with processing at the edge so video does not have to be streamed to a central cloud.

**Who it’s for:** Municipalities and city districts, traffic police and transport authorities, utilities, and smart-city system integrators and telecom operators.

## Why Nabrio in smart city

- **Processed at the edge:** Nara runs on NVIDIA Jetson devices or on-site servers, which reduces bandwidth and keeps video local.
- **One platform for the city:** Traffic, public safety and environment monitoring use the same platform and the same building blocks.
- **Tracks across devices:** Multi-device sync shares data between Nara devices, so people and vehicles can be followed across locations on a site.
- **Feeds the command centre:** Results and evidence go to command-centre systems over MQTT or HTTP.

## Use cases

### Traffic monitoring

- [Traffic flow and congestion](https://nabrio.com/use-cases/traffic-monitoring.md): Vehicle detection + tracking → counts per lane and direction, density, queue length, congestion alerts
- [Vehicle classification counts](https://nabrio.com/use-cases/traffic-monitoring.md): Cars, motorbikes, buses, trucks per hour
- [Traffic accident detection](https://nabrio.com/use-cases/traffic-monitoring.md): Detect stopped vehicles in live lanes, collisions, and crowds forming → alert the command centre
- [Licence plate recognition](https://nabrio.com/use-cases/licence-plate-recognition.md): Plate detection + OCR for enforcement, access, and investigations

### Traffic violations

- [Illegal lane change](https://nabrio.com/use-cases/traffic-violation-detection.md): Track crosses a solid-line boundary
- [Bus-lane violation](https://nabrio.com/use-cases/traffic-violation-detection.md): A non-bus vehicle in the bus-lane zone (during restricted hours)
- [No-parking zone](https://nabrio.com/use-cases/traffic-violation-detection.md): A vehicle stationary in the zone longer than a set time
- [No-stopping zone](https://nabrio.com/use-cases/traffic-violation-detection.md): A vehicle stops in the zone for longer than a set time
- [Parking violation (double parking, wrong bay)](https://nabrio.com/use-cases/traffic-violation-detection.md): Zone + dwell time + vehicle type
- [Wrong-way driving](https://nabrio.com/use-cases/traffic-violation-detection.md): Track direction against the allowed direction
- [Motorbike or car on the pavement](https://nabrio.com/use-cases/traffic-violation-detection.md): A vehicle track inside the pavement zone
- [Crossing the pedestrian crossing on red](https://nabrio.com/use-cases/traffic-violation-detection.md): Vehicle in the crossing zone while the pedestrian signal is green (needs signal state)
- [Red-light running](https://nabrio.com/use-cases/traffic-violation-detection.md): Stop-line crossing while the signal is red (signal state from the controller or camera)
- [Over-speed detection](https://nabrio.com/use-cases/traffic-violation-detection.md): Tracked distance over time with a calibrated camera
- [Evidence capture](https://nabrio.com/use-cases/traffic-violation-detection.md): Every violation: plate read, images, timestamp, location to the database or back office

### Public spaces and safety

- **Hawker (street vendor) violation**: Detect stalls and carts in restricted zones and hours
- **Crowd and overcrowding**: Crowd-counting model → density alerts for events and stations
- **Fights and violence**: Action recognition → alert patrols
- [Falls and people lying down](https://nabrio.com/use-cases/fall-detection.md): Pose and fall models → emergency response
- **Illegal dumping**: Detect dumping activity or new waste piles in watched areas
- **Smart pedestrian crossings**: Detect waiting pedestrians → adjust the signal timing

### Environment and infrastructure

- **Flooding detection**: Detect water on roads and underpasses → warnings and road-closure alerts
- **River and canal water level**: Read a staff gauge or water line from the camera → level trend, threshold alarm; fuse with level sensors over Modbus or MQTT
- **Weather monitoring**: Classify sky, rain, and visibility conditions; combine with weather sensors
- **Street-light and blackout monitoring**: Brightness per zone at night → detect lamps that are out or area blackouts
- **Pothole and road-damage detection**: Cameras on vehicles or fixed cameras → detect and geo-log damage for repair crews
- **Bridge and utility inspection**: Drone or video feeds → detect cracks and rust; log for maintenance

## Connects to your systems

Roadside and junction cameras, NVIDIA Jetson edge devices or on-site servers, and command-centre or back-office systems over MQTT or HTTP.

## Frequently asked questions

### Does video have to be streamed to a central cloud?

No. Nara processes video at the edge and sends only results and evidence to the command centre.

### Which violations can it detect?

Lane, bus-lane, no-parking, no-stopping, parking, wrong-way and pavement violations use built-in tracking, lines, zones and timers. Red-light, pedestrian-crossing and speed cases also need the signal state or a calibrated camera.
