Abstract:
A method for controlling track-bound vehicles (F.sub.n ; n=1 . . . m), comprising the following steps:(a) determining forecast delays (E(V.sub.k.sup.n); k=1 . . . 1) for each vehicle (F.sub.n) in the sequence of an order of determination (EO) for all stopping places (k) which the respective vehicle (F.sub.n) approaches in a forecasting period;(b) minimizing a destination function (.psi.) in the reverse sequence of the order of determination (EO) by using a steepest descent method which determines new control values (M.sub.k.sup.n), at least one of the following components being taken into account in the destination function (.psi.):a weighted sum ##EQU16## over at least some forecast delays (E(V.sub.k.sup.n); k=1 . . . 1) a weighted maximum delay ##EQU17## of said vehicle (F.sub.n); a weighted sum ##EQU18## over an unexpected spacing (E(A.sub.k.sup.n)) of the respective vehicle (F.sub.n) from its direct predecessor at the stopping place (k);a weighted sum ##EQU19## over at least some of the control values (M.sub.k.sup.n); and (c) using the control values (M.sub.k.sup.n) obtained by the method of steepest descent to control the respective vehicles (F.sub.n).
