Package org.opentrafficsim.road.gtu.generator

Class CFBARoomChecker

  • All Implemented Interfaces:
    LaneBasedGTUGenerator.RoomChecker
    public class CFBARoomChecker
extends CFRoomChecker
    Extends car-following placement with a first-order bounded acceleration (BA) principle. This principle comes down to reduction of efficiency by increasing headways, as the generated GTU speed is lower than the desired speed. The increased headways allow for acceleration to occur, allowing faster flow recovery over time.
