Most of the time, overused intersections might lead to serious traffic jams on multiple roads, which wastes drivers'time and money, and also causes unnecessary air pollution. Additionally, according to a study from the National Highway Traffic Safety administration in the U.S., it is reported that about 96% of the intersection-related crashes had critical reasons to be the drivers fault, such as inadequate surveillance, false assumption of other actions, and turns with obstructed view.

[Autonomous vehicles](https://en.wikipedia.org/wiki/Self-driving_car) (AVs) are a promising solution to traffic accidents. An optimistic prediction is that AVs will be publicly available in the next decade, and thus traffic issues related to autonomous vehicles are also being extensively investigated.
Current intersection management strategies, such as the traditional traffic lights and other more advanced methods are designed exclusively
for human drivers. With the rapid development of AVs, new traffic strategies must be taken into account.\
This is where you come in. You will have to create this new traffic strategy algorithm, so that AVs can pass an intersection without any
collisions and with a minimum of traffic congestion.

As stated above you will be considering that all vehicles are autonomous (AVs), also known as self-driving cars.
You will have to implement the physics for this type of vehicles by taking into account the following rules :
1. AVs driving on a lane with a **given route** must follow the direction of
that route, it is not possible for the AVs to change lanes or route.
1. AVs driving on a lane with a **given route** must follow the direction of that route; the AVs can't change lanes or routes.
2. AVs must have at least 3 different velocities, therefore the **smart intersection system** can control the velocity of the vehicle.\
2. AVs must have at least 3 different velocities. Therefore the **smart intersection system** can control the velocity of the vehicle.\
This will be the way of controlling the current velocity/time/distance (depending on the algorithm you implement) of the AVs.
3. Each AV must respect a safety distance from other AVs.\
If a vehicle is driving with a high velocity and encounters another vehicle, it must detect that vehicle and keep a safe distance from it. It should not collide!
You are free to decide what is the safety distance but it must a strictly positive value.

- `velocity`: the speed of the AV at current time

Animation is not just rendering an image into the canvas. By using assets you get to decide your "world coordinate system"
for the rendered image and therefore you create your own animation. But this is not enough.Basically you must animate while moving.

A simple example of movement animation is imagining a vehicle with a route of `r`. This means that the vehicle arrives at the
intersection and turns right. If we render just an image of the vehicle facing down and it arrives to the point of turning, the rendered image
