                                        throws ArrivalEstimationException

Compute the acceleration schedule and the arrival parameters at the intersection.

Parameters:

time1 - the initial time

v1 - the initial velocity

dTotal - the distance between the vehicle and the intersection

vTop - the speed limit of the road

vEndMax - the speed limit at the intersection

accel - the maximum acceleration

decel - the maximum deceleration

Returns:

the acceleration schedule and estimated arrival parameters at the intersection; null if there is no solution

Throws:

if - the algorithm returns no solution.
