1. A method for controlling trackbound vehicles (F_{n} ;
 n=1 . . . m), comprising the following steps;
(a) determining forecast delays (E(V_{k}^{n});
k=1 . . .
1) for each vehicle (F_{n}) in the sequence of an order of determination (EO) for all stopping places (k) which the respective vehicle (F_{n}) 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 (M_{k}^{n}), 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(V_{k}^{n});
k=1 . . .
1) a weighted maximum delay ##EQU17## of said vehicle (F_{n});
a weighted sum ##EQU18## over an unexpected spacing (E(A_{k}^{n})) of the respective vehicle (F_{n}) from its direct predecessor at the stopping place (k);
a weighted sum ##EQU19## over at least some of the control values (M_{k}^{n}); and
(c) using the control values (M_{k}^{n}) obtained by the method of steepest descent to control the respective vehicles (F_{n}).

Abstract
A method for controlling trackbound vehicles in which prescribed route networks and route for trackbound vehicles (F_{n}) are used to determine forecast delays E(V_{k}^{n}) for the vehicles (F_{n}), a destination function (ψ) which quantifies the various aspects of causes of delay or aspects which lead to a need to control the individual vehicles (F_{n}) is minimized, and the method of steepest descent determines control values (M_{k}^{n}) by means of which the individual vehicles (F_{n}) are controlled.
