All Implemented Interfaces:

V2IManagerCallback

public class V2IManager
extends IntersectionManager
implements V2IManagerCallback

An intersection manager that takes requests from vehicles and coordinates their traversals of the intersection to ensure that there are no collisions. The V2IManager makes its decisions using an intersection control Policy.
