# JC2066 Group project

## Drone traffic control


### Background

Traffic control in intersections and generally all crossroads had always been a problem
- Dangerous
- Wastes pedestrians' and drivers time

### Existing solutions

3 - color Traffic lights
- Stupid, traffic light duration is fixed
- Doesn't stop people ignoring red lights

Letting pedestrians press a button to speed up traffic light change
- Hygiene issues

Sensors on traffic light poles (e.g. In Hong Kong)
> [Smart Traffic Control System](https://www.lscm.hk/eng/channel.php?channel=Case-STCS)
- Small coverage, not enough for mass, smart and accurate prediction algorithms

### OUR Solution

- Inspried by the Mexican crimefighting drones mentioned by Professor Ho
- Have drones up super high in the air
- Ultra high resolution camera
- Monitor every single intersection and crossroads
- Completely capture the traffic condition in a large area
- Massive amount of data input vs mere sensors on little traffic light poles
- Allows a traffic flow prediction algorithm to dynamically change the traffic lights ON THE SCALE OF A FUCKING CITY
- Computer Vision
- Automatically identify people that disobeys traffic lawas
- e.g. Ignoring red light,
- Focus on the target car
- Follows the target car
- Drone doesn't have to move, just switch between cameras of different drones
- Saves the last known location
- Send a cropped out video file to the police department
### Potential Challenges
- High maintenance cost
- Moving parts need to be inspected and replaced
- Low uptime
- Needs to recharge
- Crossroads / Intersections under bridges
- Unable to capture areas that are invisible to bird's eye view cameras
