摘要:
The invention relates to a control system for controlling a traffic control signal, said system comprising: two control units, each of which is designed to control a traffic control signal independently of the other and each of which is designed, when the traffic control signal is being controlled by the one control unit, to take over control of the traffic control signal from said one unit. The invention further relates to a corresponding method for controlling a traffic control signal and to a computer program.

The invention relates to a method for controlling a light signal system, wherein - in a first time interval of the light signal system, signal times of a signal group of the light signal system are determined for a second time interval which follows the first time interval in time on the basis of measured traffic data, wherein - the determined signal times are kept unchanged after a predetermined time, wherein - the signal group is controlled in the second time interval on the basis of the signal times which are kept unchanged so that the signal group outputs signals corresponding to the signal times which are kept unchanged in the second time interval, - wherein rest times for the signal images of the signals are determined from the signal times which are kept unchanged if the signals are switched in the second time interval, - wherein the predetermined time is determined in such a way that the rest times determined for each future time remain unchanged for signal images of the light signal system which are running at that time and that the next switching time of a signal is present at the latest at the time of the preceding switching time. The invention furthermore relates to a light signal system control system for controlling a light signal system and to a computer program.

The invention relates to a system for determining traffic information. Said system comprises a terminal (1) which is carried along in a vehicle (V), said terminal having a position determination device for determining the position (P) of the vehicle (V) in a road network, a storage device for storing reference positions (R) defined by the location coordinates, and a processing device which works together with the position determining device and the storage device. Said processing device is designed to compare a specific position of the vehicle (P) with stored reference positions (R) in order to determine whether the vehicle (V) has passed a reference position (R). According to the invention, a reference position (R) is defined by a safety line (L) extending through the location coordinates thereof, said processing device is designed to determine whether the vehicle (V) has traversed a safety line (L) and to evaluate the traversing of a determined safety line as the vehicle passes the reference position (R) defined by the safety line (L). As a result, a system which can determine a position in a simple and reliable manner, also in an inner-city road network, is provided.
