##### Try to generate four vehicles at the same time, one using the `"Down"` key and the other using the `"Right"` key (repeat this operation until there is a collision route).
###### Did the traffic congestion remained low while running the application? (ex: high traffic congestion can be 8 or more vehicles stuck in the same lane)?
##### Try to generate four vehicles using the `"UP"` key to generate two and the `"Right"` key to generate the other two. Then when the vehicles finish passing the intersection, exit the application by using the `"Esc"` key.
##### Try to generate one vehicle and see how much time the vehicle takes to leave the intersection, then exit the application and compare the time statistics.
