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.
