This project aims to explore the interaction of automatic cars from a simulation platform. It used a built-in example class, allowing users to simulate automation cars move and change their routes in a virtual map. The vehicles utilize Dijkstra and two variations of the A-Star algorithm to find and replace the route based on traffic conditions that reduce the driving time. After several simulations, it figured out "Dijkstra" is the best for search path during the driving. However, allowing to change route during the travel might not suitable to improve the whole traffic performance.
