Constructor Detail

VelocityProfileArray

public VelocityProfileArray()

constructor.

VelocityProfileArray

public VelocityProfileArray(Train simulatorTrain,
                    Block currBlock,
                    double startVelocity,
                    double finalVelocity)

1) It calculates velocity of the train for every tinyblock in the middle of the blocks. Depending upon the direction of the train it can predict the velocity of the train in a particular region considering the speed restrictions and newtonian laws of motion. It uses Max_forward and Max_back arrays of velocities to handle the various speeds of the train in the tinyBlockRegions depending upon the direction of the train in forward or backward direction. 2) After calculating the velocities at the end of the tinyBlocks it calls calVelocity(first1, last1, (accel + tempTinyBlock.accelerationChange), (deccel + tempTinyBlock.decelerationChange), tempTinyBlockSpeed, currentBlockStartMilePost, tempTinyBlock.endMilePost); with proper parameters to finetune the acceleration and deceleration parts of the tinyBlockList. calVelocity returns a velocityProfileArray consisting of 3 parts accelerating, constant velocity and decelerating part which is then added to the main VelocityProfileArray of the constructor.

Parameters:

simulatorTrain -

currBlock -

startVelocity -

finalVelocity -

returnInterval

public VelocityProfileArray returnInterval(double milepost1,
                                  double milepost2)

VelocityProfileArray: VelocityProfileArray returnInterval(double startDistance, double endDistance) 1) It runs through the velocityProfiles in the current velocityProfile and keeps on adding time for each of the velocityProfile. 2) It keeps adding the velocityProfiles in the current velocityProfile to a new blockVelocityProfileArray so that it can get the velocity descriptions at the beginning, middle and end of this particular current Block. If the GlobalVar.overlap is true: velocityprofilearray1 = velocityprofilearray.returnInterval( GlobalVar.overlapStartDistance, GlobalVar.overlapEndDistance); return new RunTimeReturn(velocityprofilearray1.runTime, 0.0D, velocityprofilearray1);

Parameters:

startDistance -

endDistance -

Returns:

VelocityProfileArray
