"Traffic lights and their control"

The invention relates to a traffic light with three priority lamps for the green, yellow and red light, which are to be brought to light one after the other ira the rhythm of the ampal control.

The conventional traffic lights light up alternately green, yellow and red in one or more directions, whereby the sequence of the individual lights is mandatory ISt ₁ during the duration of the green, white and red phase depends on the prevailing local conditions. The traffic lights are either automatically timed or the traffic lights are controlled manually. The latter especially when the traffic

The invention is based on the object of creating a traffic light which, in addition to the usual entry signs, is also connected to a warning device. This is achieved with a traffic light with three right-of-way lamps for the green, light and red light "the 1 * rhythm of the traffic light control to light up laterally one after the other" is essentially achieved according to the invention "because within the reflector of a stared right-of-way lamp EusKtslieh as well as the usual right of way light a warning light bulb is arranged, the voltage supply line of which is separated from that of the priority lights. This catfish can be reached by a traffic light of the type mentioned in the introduction, which fully fulfills the aforementioned task. In particular, with the new traffic light, in addition to the usual right-of-way operation, a warning operation that is completely separate from the right-of-way operation is also possible. After switching off the normal Vorfahrtab "drives · and turning on the warning light like light in all lights the Warnllctitblrnen, so'dafi is hampered towards the Verkehrskreusung propelled Notelnaatsfahrseug neither fllefienden in his own direction traffic, nor by oncoming traffic on his journey · The In particular, not because of that, because while passing the intersection through the

Emergency response vehicle at all traffic lights the warning light lights up « consequently all traffic, from all directions, comes to a standstill.

The invention also provides that either the right-of-way lights are to be connected to a time-controlled traffic light voltage or the warning light bulb to an uncontrolled voltage. This ensures with certainty that there is either only priority operation or, if only waiting operation, so that between the same time there can be both priority operation and warning operation.

In a traffic light control of the type mentioned above, the traffic light is assigned a receiver, whereby the modulated voltage picked up by the latter is amplified in a high-frequency and low-frequency amplifier and filtered in several filters for the modulation frequencies to the traffic light and the latter is connected to the voltage captured by the antenna and allowed to pass through the particular filter via a remote line branching off from the voltage supply line to the traffic light, so that in this way it is not possible to influence the Aapel operation ;

Since, with the known traffic light control, the traffic in the direction of travel of the vehicle and the oncoming traffic can continue to flow undisturbed "the emergency" emergency vehicles through the in their direction of travel Traffic continues flowing at their driving speed limited “before all” but “because of the oncoming traffic” you cannot carry out any overtaking server.

In contrast, the invention is based on the further object of creating a control system which does not adhere to the aforementioned disadvantages, which is rather designed in this way. dafi al · completely independent of the others Traffic light control devices are to be operated.

Make contacts to the uncontrolled warning light voltage for the duration of the switch actuation 1st and at the same time the right-of-way light Above the break contacts of the tent-controlled traffic light voltage are to be switched off. To this In this way one arrives at a traffic light control »which fully fulfills the aforementioned inventive task.

It is also essential to the invention that if present a manually operated central control that controls the receiver can own.

According to another feature according to the invention, let that after putting the Warnliohtbirne out of operation, the right of way lamps for yellow light switched on and after predetermined Time the right-of-way lights for green or red light are switched on for normal operation. Thus, after the Warning light operation a neutral transition period.

The switching for red or green following the yellow phase g after the previous warning color is advantageously dimensioned so that if, for example, the green light of the traffic light comes on before the warning light is switched on, this green light is continued * provided that the green light has been on for so long If the continuation of this would only lead to a further green light of only a short time, then the port setting of the green light does not take place in order to fully utilize the entire green light phase according to the time control of the traffic light, but a switch to red light. However, it may also be the control provided that occurs after interruption% of the green light by the warning light, the reclosing of the green light NaOH previous yellow light to the interruption taken into account by the warning light. This reactivation of the örünphase or also the red phase should take into account that the warning signal caused a delay in traffic, which requires a certain amount of time to start.

In the voltage supply lines 21, 22 and 22 * 24 to the right of way bulbs 17 »18 and 19 as well as in the voltage supply lines 19 and 20 to the warning light bulb 42, a receiver-operated switch 27 is provided which, as shown in FIG is, consists of the receiver 28 with the antenna 29 and the coil 20, the amplifier yi, the rectifier 22 and the switching relay y ^ for the direct actuation of the switch pin 24. The latter is with the four normally closed contacts 25 * 26 »27 and 28 for closing or opening the voltage supply lines 21, 22, 22 and 24 to the right-of-way bulbs 17 * 18 and 19 and the Arbeltskomtakte 29 and 40 for opening and closing the voltage supply lines 19, 20 connected to the warning light bulb 42.
