Problem Statement
Consider the problem: We have a busy crossroad with 4 traffic light clusters. We have traffic camera(s) that can give us information about the directions each car is travelling.
What is the optimal green-light time for each travelling direction at the crossroad?

Our Approach
1. Infer the traffic flow for each of the 12 possible travelling directions at the crossroad
We utilizes the data from the cameras to perform
2. From the traffic flow, calculate the optimal green-light time for one of the two sides of the crossroad.

Our Approach
| First step | Second step |
| Performed with a deep neural network model for object detection and tracking | Performed with a deep reinforcement learning model to calculate the green-light time |
| We refered to the paper "Zero-VIRUS: Zero-shot VehIcle Route Understanding System for Intelligent Transportation"[1], and used transfer learning to re-trained the model with our custom dataset. | We first created SUMO simulation based on real-life traffic data. For the model, we built a Deep Q-Network. We then train the model in that simulated environment. The model was trained in 10 epochs with 200 steps. |

Advantages
Reduce costs
Comparing to the conventional methods, this system reduces the cost of building infrastructure, implementing 5G connection, and reduce the time of transmitting data.
Extendable
Since AATLAS can receive as many junctions as possible, it can be well implemented at national level.
Asynchornized system
We can create a network of AATLaS working simultaneously
