摘要
A method and a circuit arrangement for modifying central control information commands forming signal programs in traffic signal systems in particular street traffic signal systems, the central control information commands being output from a central station to intersection devices of the system in order to control signal generators assigned to the intersection devices. This modification is to occur through the use of traffic information which are determined in the traffic areas whose traffic flows are to be controlled by the signal generators of the intersection devices. In order to be able to undertake a modification of the signal program sequencing in the respective intersection devices, modification time areas are determined in the form of partially overlapping central control information commands, in particular binary "1's" transmitted from the central station to the respective intersection device. Within these modification time areas, separate local control information commands can become effective for setting the signal generators.
