public class ChannelTaskSignal
extends AbstractTask
implements ChannelTask

Task demand for signal (front: brake lights, left: right indicator, right: left indicator). This applies to the first leader with signal, and is defined as TD_signal * (1 - s/x0), where TD_signal is a constant, s is the distance to the leader with signal and x0 is the look-ahead distance.
