public class ChannelTaskAcceleration
extends AbstractTask
implements ChannelTask, Stateless<ChannelTaskAcceleration>

Task demand for acceleration from stand-still or low speeds. This mostly functions to increase attention when leaving a queue. This is defined as the maximum of max(0,-dv)/v0 * (1-s/x0), where dv is the approaching speed to a leader, v0 is the desired speed, s is the distance to the leader and x0 is the look-ahead distance.
