Fig. 13.9. Speed modeling using acceleration profile
geometrical representation of the moving object’s route, (2) an acceleration profile,
mopa.apf , for speed prediction along the route, (3) the location of the client, mopa.m,
given as a measure value on the route, (4) the speed, mopa.plspd, of the object, and
(5) the time, mopa.t, when the location and speed are acquired. Parameter t > mopa.t
is the time point for which the location of the object should be calculated. The result
is the coordinates of predicted location of the object at time t.
