摘要： Control logics for the traffic-dependent controlling of traffic signal installations (1) are described with flow diagrams that become increasingly difficult to understand as phase sequences become more complex, and can only with difficulty be converted, in automated fashion, into traffic-oriented descriptions for signal programs. In a database data file (15), conditional equations (B1, B2, B3) that compare traffic-oriented characteristic quantities with predetermined threshold values are stored together with actions (A1, A2, A3, A4) for exchanging signal programs and together with rules (R1, R2, R3, R4). The rules (R1, R2, R3, R4) have control values and action directions (X). The control values are compared with truth values of the conditional equations, and, given complete agreement between the control values of a particular rule and the truth values, the action (A1, A2, A3, A4) to which the action indication (X) of the particular rule (R1, R2, R3, R4) refers is executed.
