1. A method for controlling track-bound vehicles (Fn ;

  • n=1 . . . m), comprising the following steps;

    (a) determining forecast delays (E(Vkn);

    k=1 . . .

         1) for each vehicle (Fn) in the sequence of an order of determination (EO) for all stopping places (k) which the respective vehicle (Fn) approaches in a forecasting period;

    (b) minimizing a destination function (ψ

    ) in the reverse sequence of the order of determination (EO) by using a steepest descent method which determines new control values (Mkn), at least one of the following components being taken into account in the destination function (ψ


    a weighted sum ##EQU16## over at least some forecast delays (E(Vkn);

    k=1 . . .

         1) a weighted maximum delay ##EQU17## of said vehicle (Fn);

    a weighted sum ##EQU18## over an unexpected spacing (E(Akn)) of the respective vehicle (Fn) from its direct predecessor at the stopping place (k);

    a weighted sum ##EQU19## over at least some of the control values (Mkn); and

    (c) using the control values (Mkn) obtained by the method of steepest descent to control the respective vehicles (Fn).
