Note
If b > predMaxDecel, this function actually does not calculate the tangency for the trajectories, i.e. a double root for the gap, but applies a simpler approach following the spirit of maximumSafeFollowSpeed, where the leader's decel is assumed as maximum of its actual value and the followers decel.

◆ speedAfterTime()

double MSCFModel::speedAfterTime ( const double  t,

Calculates the speed after a time t \in [0,TS] given the initial speed and the distance traveled in an interval of step length TS.

Note
If the acceleration were known, this would be much nicer, but in this way we need to reconstruct it (for the ballistic update at least, where we assume that a stop may occur within the interval)
Parameters
[in]ttime in [0,TS] for which the speed shall be determined
[in]oldSpeedspeed before the last time step (referred to as t == 0)
[in]distancecovered
Returns
speed at time t
