Description

The invention relates to automatic, self-regulating traffic control devices and in particular to a device for regulating vehicle traffic at road junctions.

The device for traffic control according to the invention is limited in its Area of application not only for the regulation of road traffic, but is also

to that with the same ease with any intersecting traffic directions to apply where an automatic regulation of the traffic route at the intersection out of consideration for the companions who pass the crossing point want to run over is desirable. Such a device can therefore be used, for example, at level crossings where a suitable warning signal is to be put into operation.

ao A mistake in the usual "stop" and "drive free" device, the signals for the streets Traffic regulation is used and influenced by a time device which the Signals take effect in a periodic sequence regardless of traffic conditions lets, consists in the fact that they very often the stop signal to the moving companion in order to give the right of way to the traffic present in the intersection street, if at all in this intersection street there are no waiting companions. Another flaw in these ordinary timing devices is that the Right of way is given to one street longer than necessary, so that that in the other No need to wait for the car on the road. Due to these circumstances, will all traffic is uselessly held up, and unnecessary ones arise at the intersections Accumulations.

The main aim of the invention is to create a self-regulating traffic monitoring device, which depends on the current volume and distribution of the traffic is working. This goal is achieved by a mechanical traffic control system, which works depending on the particular condition of the traffic flow and the required signal with regard to the extent and distribution currently available and not below adjusts to the influence of an arbitrary timer.

Another object of the invention is to provide a traffic control device, in which the display signal through the traffic in conjunction with a time

device, by the time device itself or by both devices in the following How is influenced:

i. the right of way becomes successively different traffic facilities in one Order given, which can be determined in advance, but in such a way that the Time for which the right of way is allocated to a traffic direction, depending on either ίο from the approach of the vehicles in the said direction, from the Approach of the vehicles in one or more other directions or dependent of both is;

2. A traffic direction that does not need the right of way receives the right of way not allocated to the detriment of the traffic direction it requires;

3. a vehicle that moves forward through a steady flow of traffic Transverse direction is prevented does not need to wait more than a set time, and this vehicle is granted right of way for a time required to cross the intersection required, or the right of way is granted to this and the following vehicles for the specified time mentioned above;

4. Disruptive traffic directions cannot get the right of way at the same time; 5. a vehicle that has run over the trigger is protected against the traffic flowing in the transverse direction for so long, that the said vehicle cross the intersection of the traffic directions can;

6. A vehicle approaching an intersection in any direction of traffic approaches, right of way is granted, provided that no one is in the Cross direction flooding traffic crosses the intersection or the intersection approaching;

7. if a vehicle is not immediately given the right of way or a vehicle the right of way is withdrawn before there has been enough time to reach the crossing point To achieve this, the facility is left in such a state that right of way the handicapped vehicle is recognized as soon as possible;

8. Continuous vehicle traffic in one direction is periodically interrupted in order to to give pedestrians the opportunity to cross this direction of traffic, and even if there is no vehicle traffic in the direction of pedestrian traffic;

9. if the signaling means and the timing device are out of context with the through the traffic are affected tripping, the right of way is successively the different Traffic directions issued according to a predetermined sequence and in each case for a specific period of time;

10. By simple setting within the facility, all can be set Time periods and dependencies related to the traffic in the different traffic directions can be changed so that an adaptation to the most diverse distributions and traffic densities is obtained.

A signaling device for the automatic regulation of the traffic at danger points is known, in which the right of way depends on both a time switch and on pulse generators influenced by vehicles is. In contrast, according to the invention, there is only a single signal system, both from the timer and from all the pulse generators different traffic directions is controlled.

The invention will become more clearly recognizable when the switching arrangements and devices indicated in the figures are considered more closely.

A self-regulating automatic traffic control device according to the invention is composed of three parts: the contact devices that cross a part or half the width of the street are arranged in the road embankment, the electric Control device and the carrier for the signals for issuing the right of way for traffic. How the Display device is such that one of the no intersection of two or more traffic directions 'approaching vehicle energizes an electrical monitoring circuit. How the electric The time-limiting control device consists in that it is activated by crossing the contact thresholds is actuated by a vehicle and this actuation either immediately or after a certain time on the signaling means transmits, which then show the vehicle right of way or stop. The signaling means, which inform the traffic whether to stop

has or can continue to flow, consist expediently in the usual way of red, yellow and green lamps. However, other signals can also be used within the scope of the invention use, for example, signal arms, horns or bells or any other equivalent signals. The facilities affected by the vehicle or the Pulse generators can also be of various types.

So you can set a contact threshold in

Provide a road that extends over half or the entire width of the street and which make electrical contact under the influence of a vehicle driving over it. - represents.

The time-limiting control circuit • works as follows: Provided that no vehicle is approaching the intersection of the streets marked A and B , a yellow signal light is visible in both streets. A vehicle approaching the intersection on yi-street acts on the contact threshold located in yi-street, with the result that the circuit is immediately closed by contact relays. As a result, the green light on ^ 4-street and the red light on ß-street light up and at the same time the yellow lights in both streets go out. ^ 4-Straße now has right of way. For the disappearance of the green light of the yi street, the following conditions must be taken into account:

1. when all traffic in ^ -strasse has passed the intersection then the green light goes out;

2. when the traffic on y4 street is on At the end of a predetermined time, for example 30 seconds, still floods, then it will suppresses the green light to allow pedestrians to cross ^ 4 street;

3. when the traffic of yi street is still at the end of the 30 seconds flows and companions wait in the B-street, then that will put the green light on yi street out in favor of B street.

These time limits during which on ^ Street keep the green light on are monitored by suitable delay relays, which are described below.

To extinguish the green light of the ^ 4-Straße in the case mentioned under 1,

d. H. if the traffic on ^ 4-Straße die Has crossed the crossing point, a delay relay is used through which the circuit for the green light of the ^! - street and for the red light of the B-street is opened after the relay for a predetermined time, for example for 10 seconds, was constantly aroused. This relay is always energized again offset, as soon as a car affects the contact threshold located in the. ^ - street. Thus, in the event that a small number of vehicles that the intersection with only for a short time Want to occupy the fitting, is located in the .4-Straße, this relay work so that the Green light goes out 10 seconds later after the last vehicle is in the . ^ - Cross the contact threshold on the street Has. Now the green light of ^ street and the red light of B street will go out and the yellow light will reappear in both streets. Listen on the other hand the traffic in the. ^ - street not on, so the 10-second relay will constantly put back into a state of excitation and thus the interruption of the circuit for the green light on yi street and the red light on B street. In these circumstances another delay relay comes in for a particular one Time, for example 30 seconds, is set to take effect. The way of working this relay is described in the next sections.

In order to do justice to the above-mentioned case 2, in which a constantly flooding traffic in the yi-street has to be stopped so that pedestrians can cross the A-streets , another delay relay is the circuit for the green light of the yi-street and the red light of the B-street opens, switched in such a way that it comes into a state of excitation when the yl-street is equipped with a green light. - This relay is not put into the initial working state by the vehicles that drive over the contact thresholds in ^ 4-Straße. The right of way for ^ -strasse ends 30 seconds after the point in time at which it was granted, unless the 10-second relay is energized earlier in consideration of the end of traffic in ^ -street.

The interaction of these delay relays has the consequence that the green Light in ^ 4-Strasse only shines for 30 seconds when traffic in. ^ - Strasse das requires. Has all the traffic in Yä Street passed the intersection, so the green light goes out before the 30 second period.

The monitoring circuit is designed so that when the green light for the ^ 4-Straße has expired with regard to one of the above conditions, in both roads during a backup period

the yellow light appears. After the backup time, the waiting traffic determines which road is granted the right of way. Waiting vehicles in both streets then 5-street is awarded the green light. Located on ^ 4 Street only Waiting traffic, then the green light comes on again in ^ -Straße. If there is no waiting traffic in both streets, then yellow light will appear in both streets until a Vehicle is approaching. The right of way is then immediately given to the approaching vehicle granted. The details are contained in the section of this specification which relates to the operation of an exemplary switching arrangement according to the invention relates.

If, at the end of the yellow safety period, vehicles have influenced the contact thresholds in 5-street 10 seconds before the right of way for this street is revoked, then the green light is assigned to ß-street. If, however, the contact thresholds in .B-Strasse remain unactuated within 10 seconds before the green light in .B-Strasse goes out and, on the other hand, the contact thresholds in ^ -strasse have been influenced within 10 seconds before the green light in yi-Strasse goes out then the right of way on yi Street will be granted after the yellow safety period has expired. If the contact thresholds in both streets remain inactive for 10 seconds before the street in question has lost the green light, the yellow lights will remain until a vehicle approaches. The right of way • is then immediately given to an approaching vehicle in any street. It is possible that a vehicle on ^ 4-Strasse approaches the intersection within the last few seconds of the 30-second section of ^ 4-Strasse. The light 45- could go out after the said vehicle has driven over the display device, but before it has already passed the intersection. The vehicle would then be stopped between the contact threshold and the intersection. In order to give a vehicle that has been shut down as quickly as possible, the circuit is designed in such a way that the action of the contact threshold in ^ -Straße during the 10 seconds immediately preceding the extinguishing of the green lamp in ^! - Street (assuming that the green light of the yi-street is extinguished by the 30-second relay), has the consequence that the green light of the νϊ-street at. the first opportunity granted again and in this way the decommissioned vehicle is released. For this reason, the expression "within 10 seconds before the green light in the relevant street goes out" has been chosen in the previous section. We have already spoken of the delay relays, which limit the time during which the. ^ Road can maintain right of way. Another similar delay relay device dominates the .B-street, as well as the .B-street has the right of way. The mode of action here is exactly the same as with the A-road.

The relay system contains a pair of delay relays that only take effect come when a certain time, for example 2 seconds, has passed after their arousal are. These relays control the length of the safety period between the red and green light periods. The invention is described below using an exemplary embodiment.

In Fig. Ι is a complete, self-regulating traffic control device for; the intersection of two streets A and B is shown. The contact thresholds are indicated by the reference numerals 4, 5, 6 and 7. Reference number 9 indicates the signals. In the signal direction there is a red and a green electric lamp, which can be seen from any point within ^ 4-Strasse, but cannot be seen from .B-Strasse. Correspondingly, a red and a green electric lamp are provided for the 5-street, which are not visible for the yi-street. Finally, there is a yellow electric lamp visible to both streets. The green light for the yi street and the red light for the B street are energized via the lines 87 and 73. The lines 88 and j6 ensure the suppression of the green light in the B-street and the red light in the ^ -street. Wires 72 and 75 provide power to the yellow light.

The electrical time-limiting device is indicated by 8 in Fig. 1. links 10, ri, 12 and 12 'connect the parts of the contact thresholds located in the ^ 4-Straße with each other, whereby the wires 10, 11 and 12 also connect to of the electrical time-limiting device 8. Connect wires 13, 14, 15 and 14 ' the contact thresholds located in the B-street with each other, whereby the wires 13, 14 and 15 connect at the same time with the electrical time-limiting device 8.

Fig. 3 shows a contact device according to the invention. 90, 91, 92 and 93 are

electrical contacts, of which when a vehicle drives over the threshold 104 and this threshold is moved down around the pivot point 103, the contacts 90 and 91 S separated from each other and the contacts 92 and 9.3 are closed. The effect a wheel rolling over a sleeper in the ^ street consists in the opening of the circuit between wires 11 and 12 by connecting contacts 90 and 91 separated from each other, and in the completion of a circuit between the Wires 10 and 11 by connecting contacts 92 and 93 are closed. After the wheel has passed the threshold, an Spring 103 'lifts the arm 104 with the result that the contacts 92 and 93 from each other be separated. This creates the circuit between wires 10 and 11

ze opened and contact between 90 and 91 re-established. In this way there is again a connection between the wires 11 and 12 via the contacts 90, 91 and 94, 95, the latter being assigned to the other threshold of road A.

From Fig. 4 it can be seen how the contacts of the contact thresholds located in a street are interconnected. The contacts 96 and 97 are connected in parallel with the contacts 92 and 93, while the Contacts 94, 95 are in series with contacts 90 and 91. Thus has the influence each threshold has the same effect on the circuits. Fig. 2 gives the implementation and switching arrangement of a electrical time-limiting control device 8 according to the invention in detail again and also shows the electrical connections of the signal lamps. According to this figure 89 is a yellow light that can be seen from both streets, 83 a green Light, visible to 5-street, 84 a red light, visible to ^ 4-street, 85 a green Light visible to ^ 4 street, 86 a red light visible to 5 street.

The control device contains the following relays: immediately responding contact relays 26, ² 7>34> 35 and 36, relays 30 and 31 working with oil damping, which have an armature pick-up delay of 10 seconds, relays 32 and 33 working with oil damping, with an armature pick-up delay of 2 seconds and relays 28 and 29 operating with oil damping, in which the armature pickup delay is 30 seconds.

Compound I.

In Fig. 2 the circuit diagram is drawn in the state in which the yellow light is visible for both streets if there is no traffic on either street.

Case I. A single one on ^ Street vehicle is approaching the intersection.

It is assumed that a vehicle is approaching the intersection within ^ 4-Strasse and is influencing threshold 5 (see Fig. 1). The vehicle pushes the threshold arm 104 down and opens the contacts 90 and 91 (see Figs. 3 and 4). At the same time it closes the contacts 92 and 93. The arm 104 can be designed as part of a contact device. In the present case it is shown as a one-armed lever rotatably mounted at 103 and held in the rest position by a spring 103 '. The closure of contacts 92 and 93 causes a current to flow from a suitable power source through relay 26, through connecting wires 110 and in and 10 and 11. Armatures 45 and 49 of relay 26 are attracted. By touching the armature 45 with the contact 46, a holding circuit for the relay 26 via the wire 112, the contact 61, the armature 59, the wires 126 and 122 is closed. Through this holding circuit, the relay 26 is kept in the working position, despite the fact that the contacts 92 and 93 have been opened again after the wheel has continued to roll. The armature go 49 comes to rest on the contact 50. This has the excitation of the relay 34 via the wires 117, 118, the armature 98, the contact 99, the wire 119, the wire 120, the contact 6j and the armature 65 for Episode. The armature Jj now moves away from the contact 79 and comes to rest on the contact 78. As a result, the current flowing through the armature JJ and the contact 79 is interrupted and the relay 33 is de-energized, the armature via the wires 12, 122 Jj, the contact 79, the wire 127, the contacts 57, 58, 63 and 62, the wire 123 and the wire 116. The de-energization of the relay 33 results in the armature 68 becoming detached from the contact 70 and interrupts the current for the relay 35. The relay 35 is prevented in this way from switching on the green light for the 5-street and the red light for the yi-street via the armature 74 and the contact 76. The armature 68 comes to be applied to contact 69 so that current flows through wire 124 and relays 28 and 30. As a result, 28 and 30 begin to operate. the relay 30 then remains continuously energized 10 seconds after the Re has been energized lais 30, the armature 59 moves away from the contacts 60 and 61 and thereby interrupts the current flowing through the wires 122 and 126,

armature 59, contact 60, wire 113, contact 56, armature 55, wire 114, relay 32, wire 115, contact 82, armature 80 and wire S 116 flowed. The armature 65 of the relay 32 moves away from the contact 67 and makes contact with the contact 66. The relay 34 comes to waste. At the same time, the relays 31 and 29 are energized via the wire 125. The armature 71 separates from the contact 73 and makes contact with 72 . As a result, the green light 85 and the red light 86 are suppressed and the yellow light 89 is made to light up. As a result of the de-energization of the relay 34, the armature jy is further detached from the contact 78 and establishes a connection with the contact 79. This interrupts the holding circuit and releases the armature of the relay 26, which returns to its rest position (see Fig. 2). The armature 77 rests against the contact 79 and excites the relay 33. Two seconds after the excitation of the relay 33, the armature 68 moves away from the contact 69, which has the de-excitation of the relay 28 and 30 as a result. The armature 68 rests against the contact 70 again. The de-energization of the relay 28 has no effect on the circuit because it has not yet been energized for 30 seconds in a row. The de-energization of relay 30 causes contact to be made between 60 and 61; as a result, however, the relay 32 is re-energized via the wire 126. 2 seconds after the energization of the relay 32, the armature 65 moves away from the contact 66 and energizes the relays 29 and 31. The armature 65 comes to rest against the contact 67. The de-energization of the relays 29 and 31 has no effect on the circuit, since neither of them had been energized long enough to even begin the working movement. Yellow light is now visible in both streets and the entire facility is back to its original state.

Case II. Steady traffic on ^ Street, no traffic at all on B Street. If in the case just described, the crossing point from 5-street no vehicles have approached, but vehicles are flowing towards the intersection in yl-Strasse, each vehicle being the in the ^ -Straße thresholds 5 and 7 each within a period of Seconds, calculated from the previous activation of the threshold, influenced and thereby the current flowing through the winding of the io-second relay 30 at the Contacts 90 and 91 (see Fig. 4) interrupted, the armature 59 would make permanent contact with contacts 60 and 61, and the 10-second relay 30 would be prevented from to produce a current arrangement as in case I, with the result that the green light 85 in the yi street and the red light 86 in ΰ-Strasse is suppressed.

The further consequence of the constant contact of the armature 59 with the contacts 60 and 6 t is that the current flows through the relay winding 26, the armature 45 and the contact 46 even when the armature 77 has moved away from its contact 78. The purpose of this behavior will be discussed below. The 30-second relay 28, which has been energized at the same time as the 10-second relay 30, separates the circuit between the armature 55 and. the contact 56 30 seconds after its energization, whereby the 2-second delay relay 32 is de-energized. The armature 65 releases itself from the contact 67 and thereby interrupts the current switching relay 34. The armature / i switches from contact 73 to contact 72 and thereby suppresses the green light 85 in ^ 4-Strasse and the red Lieh + 86 in. B-Straße and lights up the yellow light 89. The armature 77 detaches from the contact 78, but does not interrupt the current for the relay 26, since this relay is still supplied with current via the contacts 59 and 61 of the relay 30, which are connected in parallel to the contacts 77 and 78. The fact that relay 26 remains energized causes lights 85 and 86 to illuminate after yellow light 89 has been on for a few seconds. The explanation for this is given below in detail. Thus the right of way of the street ^ is granted again after the pedestrians were able to cross the yi street for 4 seconds. The mode of operation of the switching arrangement to achieve this goal is as follows: The armature 77 rests against the contact 79 and thereby excites the 2-second time relay 33, as has been described above. 2 seconds after the energization of the relay 33, the armature 68 disengages from the contact 69 and thereby opens the circuit for the relays 28 and 30. The armature makes a contact with 56 and in this way energizes the 2-second relay 32. Seconds after energizing relay 32, armature 65 makes contact with 67, energizing relay 34. The relay 34 pulls the armature 71, that is, removes it from the contact 72. As a result, the yellow light goes out, and the armature 71 comes to rest against the contact 73, with the result that the green light 85 for the ^ 4 Street and the red light 86 for the B street will come on. This sequence of events

continues as long as vehicles pass one of the contact thresholds within ^ i-street in a sequence of less than 10 seconds and none in J5-Strasse Threshold an action is exerted. In the event that there is a threshold in the. ^ - street is triggered later than 10 seconds after the previous influence, the Process as described under case I.

Case III. A vehicle on Yi Street is followed by sin within 10 seconds Vehicle on 5 Street.

In this case, the same circuit arrangement is in effect as in case I, with the exception of the following changes: If the relay 34 is de-energized by the detachment of the armature 65 from the contact 67, the armature Jj makes contact with 7g. A vehicle influences either the threshold 4 or the threshold 6 in the 5-street, as a result of which the relay winding 2.7 has current flowing through it. The contacts of thresholds 4 and 6 are not shown in the figures, but these contacts control relay 27 in the same way as the contacts of thresholds 5 and 7 control relay 26. In the same way, relay 31 is controlled by the contacts of thresholds 4 and 6 controlled like the relay 30 by the contacts of the thresholds 5 and 7. The relay 2,7 is now held in the working position by the current flowing through the armature 47 and the contact 48, the contact 64 and the armature 62 and the wires 123 and 116 flows. The armature 77, which makes contact with 79, excites the relay 33 via the contacts 57, 58, 63 and 62, line 123 and 116. 2 seconds after the excitation of the relay 33, the armature 68 lies against the contact 4.0 70 and thereby brings about relay 35 via switch 106, wire 128, contacts 101, 100, wire 129, contacts 53 and 52 and wire 130 for excitation. The contact with 69 is interrupted and the relay 30 is de-energized, which thereby returns to its rest position and causes the armature 59 to make contact with 60 and 61. The operation of the relay 35 results in the dissolution of the contact between the armature 74 and the contact 75. The yellow light 89 is suppressed, anchor 74 is placed on the contact 76, whereby the green light 83 for the 5-street and the red light 84 for the. ^ - street .light up. The result is that the vehicle on ^ 4-Strasse has been given the right of way for 10 seconds and that at the end of this 10-second segment the signal about the yellow safety period is converted into a display for the right-of-way on ΰ-Strasse.

When the relay 35 is energized, the armature 80 interrupts the current flowing through the contact 82 and makes contact with 81 Made contact. If the relay 32 was originally de-energized by the release of the armature 59 from the contact 60, as explained under I, then the armature 65 made contact with 66 and thereby energized the delay relays 29 and 31. 10 seconds after the relay 31 was energized With regard to the fact that no threshold in the S-road had been influenced by a second vehicle, which would result in the de-energization of the relay 31, the armature 62 disconnects from the contacts 63 and 64 and de-energizes the relay 33. The armature 68 folds over from the contact 70 to the contact 69. The breakdown of the contact relationship between 68 and 70 causes the relay 35 to be de-energized. This results in the dissolution of the contact relationship between 74 and γ6 and thus the suppression of the green light 83 and the red light 84. The contact closure between 74 and 75 causes the yellow light 89 to light up. The armature 80 separates from the contact 81, excites the relay 27 via the wires 130 and 131, which results in the separation of the armature 47 from the contact 48. The armature 80 excites the 2-second relay 32 through its contact with the contact 82 via the contacts S5> 56, 60 and 59 of the relays 28 and 30. 2 seconds after the excitation of the relay 32, the armature 65 makes contact with 67 and releases away from contact 66. The delay relays 29 and 31 are therefore de-energized. Since the relay 29 had not been energized for a long enough time, it has not influenced the current flow. The de-energization of the relay 31 has the consequence that the armature 62 comes into contact with the contacts 63 and 64 and the relay 33 is thereby excited via the armature 77 and the contact 79. 2 seconds after the relay 33 is energized, the armature 68 detaches from the contact 69 and thereby de-energizes the relays 28 and 30. The armature 68 rests against the contact 70 so that the relay 35 works immediately as soon as the relay 27 is energized. The switching arrangement has now returned to the initial position in accordance with case I and in accordance with FIG.

Case IV. Steady traffic on ^ 4 Street, one waiting on 5 Street Vehicle.

In this case, the switching arrangement works according to the case II until a vehicle drives on one of the sleepers of 5-Straße. The opening of the circuit between the con-

clocks 55 and 56, which takes place 30 seconds after the relay 28 is energized, has the De-excitation of the relay 32 and thus the transfer of the armature 65 from the contact 67 on contact 66 result. By the union of the anchor 65 with the contact 66 relays 31 and 29 are energized. By the dissolution of the contact connection 65 and 67, the relay 34 is de-energized; the

Armature 71 and ¹ JJ of relay 34 drop back and suppress the green light 85 of the ^ -street and the red light of the 5-street, since the connection between the armature 71 and the contact 73 has been broken.

The armature 71 lies against the contact 72 and switches the yellow light 89 on. The armature γ], which is released at the contact 78, does not make the relay 26 currentless, since current for the relay 26 is supplied by the wire 126, the armature 59, the contact 61, 112 and the armature 45, the contact 46 will. In the meantime, a vehicle has driven over one of the thresholds in J3-Strasse, thereby energizing relay 27. The holding current for the re-

lais 2 ¹ J flows through the armature 47, contact 48, contact 64 and armature 62 after the car has passed. The armature 52 now makes contact with 53. The anchor ¹ Jj that made contact with contact 79, as well as that

Relay 34 was de-energized, relay 33 is now set via contacts 57, 58, 63 and 62 under power. 2 seconds after energizing the relay 33, the armature 68 is released from the Contact 69. That made the re-

lais 28 and 30 result. The armature 68 excited by the fact that he with the contact 70 to System comes, the relay 35 via the switch 106 and the contacts 101, 100, 53 and 52. The anchor 74 is now released from the

Contact 75 and suppresses the yellow light. He lies against the contact 76, whereby the green light 83 for the .B street and the red light 84 for the. ^ street will illuminate. The armature 80 separates from the contact 82 and makes contact with 81. Through this the relay 32 remains de-energized, despite the fact that contact 55 interacts with contact 56. Of the Armature 65 therefore remains in contact with 66 and keeps relay 29 and relay 31 energized,

assuming that a second vehicle is located on i? -street Threshold not crossed. 10 seconds after the relay 31 is energized, the Armature 62 from contacts 63 and 64, which causes the relay 33 to de-energize. The armature 68 of the relay 33 now moves away from the contact 70 and closes with it 69 Contact. This energizes relays 28 and 30. The relay 35 is thereupon

following the opening of the contacts 68,70 de-energized. The armature 74 releases itself from the contact 76; thus, the green light 83 for the 5-road and the red light 84 for the. ^ -road are suppressed. The yellow light 89 illuminates above the armature 74 and the contact 75. The armature 80 moves away from the contact 81 at the same time, as a result of which the relay 27 is de-excited, since the armature 62 is no longer in contact with 64. The armature 80 closes contact with 82 and causes the excitation of the relay 32 via the contacts 55, 56, 59 and 60. 2 seconds after the excitation of the relay 32, the armature 65 separates from the contact 66 and causes the de-excitation of the relays 29 and 31. The contact closure of the armature 65 with 6y causes the relay 34 to be energized via the switch 105, the contacts 99 and 98, the wires 118 and 117 and the contacts 50 and 49. The armature 71 now detaches itself from the contact 72. As a result, the yellow light 89 is suppressed. The armature 71 rests against the contact 73, which results in the lighting up of the green lamp 85 for the ^ 4 street and the red lamp 86 for the jB street. The armature yy is released from the contact 79; as a result, the relay 33 remains de-energized, even if the armature 57 comes to rest against the contact 58 and the armature 62 rests against the contact 63. The armature yy closes with contact 78, whereby a parallel connection to the armature 59 and the contact 61 is established. The device is then back in the state in which it was when the only vehicle affected the threshold located in the .B-Strasse. In the preceding description, it is shown how constant traffic on y4-street is interrupted for a time sufficient for a single vehicle from J3-street to cross the intersection, and how the right-of-way immediately afterwards again on ^ 4-street, their uninterrupted traffic was disconnected.

FaIlV. Continued traffic on both streets.

In this case, the circuit acts as in case II such that the right of way of the ^ -Straße merges with B-Straße; however, with constant traffic in · the B-street the contacts of the .B-street sleepers open, through which the current, which the relay 31 excited, passes through. The armature 62 therefore continues to make contact with the contacts 63 and 64. The relay 33 therefore remains energized until the armature 57 of the contact 58 moves away, which takes place 30 seconds after the relay 29 is energized. The excitement of relay 29 takes place in the same way as described under case II. The anchor 57, which is now from the contact 58 triggers, the relay 33 de-energizes. The anchor

68 moves away from contact 70 and makes contact with 69. This de-energizes relay 35, and delay relays 28 and 30 are energized. The armature 74 then moves away from the contact 76. As a result, the green light 83 for the 5-street and also the red light 84 for the yi-street go out. By placing the armature 74 on the contact 75, on the other hand, it lights up

ίο the yellow light on. The armature 80 now moves away from the contact 81. This has no effect on the circuit, since this connection is already established by the armature 62 and the contact 64 in an equivalent manner. Armature 80 makes contact with 82. Relay 32 is energized as a result. 2 seconds after the relay 32 is energized, the armature 65 moves away from the contact 66. The relays 29 and 31 are de-energized. As a result, the armature 57 closes contact with 58. The armature 65 rests against the contact 67. As a result, the relay 34 is excited via the switch 105, line 119, the contacts 99, 98, line 118, 117, contacts 50 and 49. The armature 71 separates from the contact 72. This suppresses the yellow light. The armature 71 rests against the contact 73, whereby the green light 85 for the ^ 4 street and the red light 86 for the .B street light up. The armature 77 moves away from the contact 79. The result is that the relay 33 remains de-energized, even if the armature 57 makes contact with 58 and the armature 62 rests against contact 63. The armature 77 makes contact with 78. Now the circuit is again in the state in which it was initially.

Compound II

The processes described under Cases I, II, III, IV and V occur when the different switches are in the position shown in Fig. 2. Out of consideration 2 it can be seen that when the switch 16 is closed, the relay 26 remains constantly excited and thereby the right of way of the ^ 4 road after every yellow one Period is returned, the 'a green period for 5-street or a green period preceded the ^ 4 road was if there was no S-road threshold within 10 seconds before the 5-Street last lost the right of way, has been affected, causing the discomfort of the relay 27 is secured.

Compound III

From the consideration of Fig. 2 this goes

further shows that when the switches are in the position shown in Fig. 2, except for the switch 17 to be assumed closed is the ratio of the switches is the same as the ratio described under compound II, except for the difference, that the conditions for ^! - Street and 5-Street have been changed.

Compound IV

If both switches 16 and 17 are closed, then the right of way is alternately granted to each street, in such a way that it belongs to each street for a period of between 10 and 30 seconds. If no vehicle in one of the two streets influences the threshold during the io-second segment, then the io-second relay comes into effect and cuts off the right of way for this street 10 seconds after it was allocated. If, on the other hand, any threshold in the street with the right of way is influenced by vehicles at intervals of less than 10 seconds, the 10-second relay is repeatedly reset to the de-energized state, so that in this case the 30th -Second relay cuts off the right of way 30 seconds after it was granted.

Compound V

From Fig. 2 it can also be seen that when all the switches in the illustrated Position are, with the exception of the switch 21, which is in contact with the contact 38 is, the opening of the contacts 59 and 60 does not de-energize the relay 32 until the relay 27 is excited by a vehicle that influences the threshold located in 5-street. Thus, the io-second relay 30 opens the circuit to withdraw the Right of way from the ^ ί-Straße not unless a vehicle is one of the thresholds of the .B-Strasse within 10 seconds before the S-Strasse last lost the right of way, influenced.

Compound VI ^x ° ⁵

Are all switches in the state given in Fig. 2, with the exception of the Switch 20, which should make contact with 37, then the conditions are as under connection V, with the only difference that the conditions for the ^ -strasse and the .B-Strasse must be replaced.

Compound VII

If all switches are in the state shown in Fig. 2, except for switch 18, which is to be thought transferred from contact 24 to 22, then relay 28 is energized, when relay 27 has been actuated by a vehicle that is one of those in .B-Street has influenced the current threshold. As a result-

IO

If there is constant traffic on -4-Street, where the ^! - street threshold is in Time intervals that are less than ι ο seconds are influenced that ^ 4-Straße always have the right of way, unless a vehicle is in the street a threshold in this street within 10 seconds before the J3 street to the last Times has lost the right of way, has affected, since the relay 27 is energized in this case is, with the result that the relay 28 via the contacts 52 and 53 is energized will. 30 seconds after the relay 28 is energized, it causes the right of way to be withdrawn from ^ 4 Street.

Compound VIII

Are the switches in the position shown in Fig. 2, except for switch 19, the is to be thought transferred from the contact 25 to the contact 23, then the relationships are as under connection VII, with the difference that the conditions for ^ i-street and 5-street have to be interchanged are.

Compound IX

Are the switches in the position shown in Fig. 2, except for switch 18, the Makes contact with 22, and the switch 21, which makes contact with 38, then remains the right of way on ^ -strasse, once it has been granted, continued, indifferent, whether or not a ^ road threshold is affected until a vehicle is in the ß-Strasse a threshold located here is actuated within ro seconds before the 5-Strasse last lost the right of way.

The relay 27 excites the relay 32 by opening the contacts 52 and 54, wherein It is assumed that the 10-second relay 30 has already opened the contacts 59 and 60 Has. In the event that a vehicle crosses the threshold within a period of time has operated for ro seconds, the armature 59 will be in contact with 60. This causes current to flow through relay 32, anyway contacts 52 and 54 are open. After the io second time has elapsed adjoins the influence of any ^ road threshold, the contact 59 is released from contact 60, relay 32 is de-energized, with relay 27 being energized. That Right of way will therefore be taken immediately from ^ 4-Straße. When on the other Side vehicles within the ^! - street the yi-street thresholds at time intervals, which are less than 10 seconds affect and so the anchor in contact with the Contact 60 received, then the relay 28 comes into effect and opens the contacts 55 and 56. Thus, the relay 32 is de-energized 30 seconds later than the R_elais 27 through a .B road threshold which has been actuated by a vehicle is influenced.

Connection X

Are the switches in the position shown in Fig. 2, with the exception that the Switch 19 makes contact with 23 and Switch 20 contact with 37 closes, then the same conditions result as under Compound IX, with the difference that the conditions for the / 4 road and the 5-street are to be exchanged.

Compound XI

If the switches are in the position shown in Fig. 2, except for switch 16, which is to be thought of as closed, the switch 18, which may make contact with 22, and the switch 21, which is applied to 38, then the right of way becomes the ^ -Straße after given back to any yellow period following a period during which the 5-street had the right of way, or which follows a period in which the. ^ - street had right of way provided that no vehicle was within a ^ 'threshold 10 seconds before the .B-Street lasts the go Lost right of way, affected. ^ 4 Street retains right of way until one Vehicle affects any of the .B road bumps and thereby energizes relay 27. After that, the right of way is instantly taken away from yi Street when there is no vehicle affected one of the thresholds of yi street during the previous 10 seconds has, or the right of way becomes the ^ 4 road through the operation of the relay 28 Taken 30 seconds after his arousal when continued intercourse in the ^ -strasse the 10-second relay at the Prevents taking away the right of way. The relay 28 is through the contacts 52 and 53 excited; the contact closes when the relay 27 is energized

Compound XII

If the switches are in the position shown in Fig. 2 no, with the exception of that the switch 17 is closed, the switch 19 contact with 23 and the switch 20 has contact with 37, then the relationships are similar to those under connection XI, except for the change that the conditions for the ^! - street and the ß-street are to be replaced.

Compound XIII

If the switches are in the position shown in Fig. 2, apart from switch 16,

which should be closed, and the switch 2i, which is also in the closed position then the right of way of the road will be given after each yellow period, in front of which the B-street had the right of way, or the right of way becomes the street ^ 4 granted after a period of time during which ^ 4-Straße had the right of way, unless a vehicle is one in the B-street

ίο located threshold within io seconds had influenced before the B-Straße last lost the right of way. Under these conditions the. ^ - street, provided that that no vehicle interferes with any threshold of the B-road for an extended period of time, the right of way continued with the only restriction that every 30 seconds a yellow time period of 4 seconds is switched on, whereby the green light for the yi street and the red one Light for the B-street are suppressed. Lights up again immediately after this period the green light for the νί-road on, d. H. ^ 4-Straße has the right of way.

The yellow time slot is provided to allow pedestrians to cross the ^ / - street. In the switch arrangement as described immediately above, when a vehicle crosses a ^ -road bump, the relay 27 is energized and the right-of-way of the B-street is granted immediately after an intermediate yellow period, provided that no vehicle is in any of the ^ 4 bumps during the previous 10 seconds. On the other hand, if a vehicle has interfered with any of the ^ road bumps during the 10 second segment immediately preceding actuation of the B bump, then relay 32 will be energized through contacts 59 and 60 regardless of the circuit at the open contacts 52 and 54 is interrupted. The armature 59 is in connection with the contact 60 since, under the conditions given above, the relay 30 has not been continuously energized for 10 seconds. In the event that vehicles interfere with the ^ -road thresholds in time segments which are each less than 10 seconds, the relay 28 operates 30 seconds after the right-of-way of the ^ 4-way has been given, with the result that the right-of-way of the street has been given A is withdrawn by means of the de-energization of the relay 32 through the opening of the circuit at 55 and 56. The behavior of the switching devices located behind the relay 32 has not been dealt with in this context, since the processes that follow the de-energization of the relay 32 always up to the point at which the relay 34 gives the green light for the ^ road and suppresses the red light for the B-road and lights up the yellow light, are the same. The transfer of the armature 71 from the contact 73 to the contact 72 plays a role here. The movement of the armature 71 is based on the de-energization of the relay 34 and is carried out entirely by the armature 65, which moves away from the contact 67 when the relay 32 is de-energized.

Compound XIV

If the switches are in the position shown in Fig. 2, with the exception that the switch 17 is closed and the switch 20 makes contact with 37, then are the procedures are the same as under compound XIII, with the difference that the conditions for the ^ -strasse and the B-street have to be exchanged.

Compound XV

The circuit is arranged so that at will those affected by the traffic Facilities can be switched off for any reason. This can be done, for example, with the switch 107 in such a way that a go connection with the contacts 41, 42, 42 ' established and the connection with the lines 10, 11 and 12 is released. Of further by flipping the switch 108 such that a connection with the Contacts 43, 43 'and 44 made and the connection with lines 13, 14 and 15 can be resolved. Under these conditions the relays 26 and 27 constantly energized by contacts 41, 42, 43 and 44, the windings of relays 30 and 31 are no longer in connection with lines 12 and 13 * As a result, the Relay constantly without power. From a consideration of Fig. 2 it can be seen that independent on the position of the switches 16, 17, 18, 19, 20 and 21 the switching arrangement the right of way is alternately granted to each street for 30 seconds, with one intermediate, A yellow time period of 2 seconds is provided. In this case the mode of action is as follows: Assume that the switch 107 is moved to the new position before the switch 108 occupies this new position. Since the relay 26 is thus energized first, gets the yi-street the right of way in the following way: the anchor49 detaches from 51 and makes contact with 50. This creates an end clamp with the power source the winding of the relay 34 via the wire 117, 118, the armature 98, the contact

99 and the switch 105 are connected, and the other coil end of the relay 34 is connected to the other pole of the power source when the armature 65 is in contact with 67. This happens 2 seconds after the anchor 45 has made contact with 46. But this happens when the relay 26 is energized. Since the relay 34 is now energized, the armature 71 separates from the contact 72 and thereby suppresses the yellow light. The armature 71 comes into connection with the contact 73, whereby the green light 85 for the. ^ - street and the red light 86 for the B-street light up. The armature yj detaches from the contact 79. This has the consequence that the relay 33 remains de-energized when the armature 57 makes contact with 58. Armature 68 detaches itself from contact 70. This prevents the creation of an excitation current for relay 35. The armature 68 rests against the contact 69, which causes the relay winding 28 to be excited. 30 seconds after the excitation of the relay winding 28, the armature 55 moves away from the contact 56. The relay 32 is de-excited as a result. The armature 65 then detaches from the contact 6γ and makes contact with 66. The relay 34 is de-energized, whereas the relay 29 is energized. By de-energizing the relay 34, the armature 71 moves away from the contact 73. The green light for the ^! - street and the red light for the B-street are consequently suppressed. The armature 71 lies against the contact 72, whereby the yellow light is made to illuminate. The armature yy makes contact with 79, whereby the relay 33 is energized. 2 seconds after the relay 33 is energized, the armature 68 moves away from the contact 69. As a result, the relay 28 is de-energized and the contact between the armature 55 and the contact 56 is caused. The armature 68 makes contact with 70. As a result, the relay 35 is energized via the contacts 53 and 52. The armature 74 then moves away from the contact 75; the yellow light goes out. The armature 74 rests against the contact 76, whereupon the green light for the B-street and the red light for the ^ -street light up. The armature 80 disengages from the contact 82 and causes the relay 32 to remain de-energized, despite the fact that the contacts 55 and 56 are closed. 30 seconds after the relay 29 has been energized, the armature 57 disengages from the contact 58; the relay 33 is de-energized. As a result, the armature 68 moves away from the contact 70. As a result, the relay 55 is de-energized. Armature 68 makes contact with 69 so that relay 28 is energized. Since the relay 35 is now de-energized, the armature 74 moves away from the contact 76, the green light for the B-street and the red light for the ^ 4-street are suppressed. The armature 74 makes contact with 75 so that the yellow light is illuminated; armature 80 makes contact with 82, thereby energizing relay 32. 2 seconds after the relay 32 has been energized, the armature 65 is released from the contact 66, the relay 29 is de-energized. The armature 65 · rests on the other side against the contact 67 and energizes the relay 34. The relay 34 · causes that for the A-street. the green light and for the B-road the red light appears, while the yellow light is suppressed. These processes are now repeated one after the other in the same way.

Compound XVI

There is a need to use the traffic-affected facilities on yi street to separate and to connect the facilities of the B-Strasse affected by traffic leave the switches in the position shown in Fig. 2, except for the switch 107, which is transferred to the downward position and related is brought to contacts 41, 42 and 42 '. In this case it remains Right of way on ^ 4-Strasse for a period of 30 seconds, regardless of whether a in the. ^ - street is influenced by the threshold will or not. In the case of the B-street, on the other hand, the duration of the right of way depends on the influence of the in this street thresholds, so fluctuates from 10 to 30 seconds. The right of way becomes the B-street only given after a yellow period if there is one in the B-street Threshold has been affected within 10 seconds before the B-road to the last time lost the right of way.

Compound XVII

If the switch 108 is used in place of the switch 107 transferred to the lower position, then the same conditions arise as under compound XVI, except for the difference that the conditions for the ^ road and the B-street are to be replaced.

The circuit is arranged so that manual control can be used. This is done, as will become apparent from the following illustration, by means of the switches 105 and 106. In order to shine yellow light in both streets, the Switches 105 and 106 placed in such a position that the contact blades make no contact produce. The relays 34 and 35 are then de-energized and the yellow light lights up by current flow through contacts 71, 72, 74 and 75. To get the green light for that

^ -Street and the red light for the B-street appear, the contact blades of the switch 105 are placed on the left contacts. This energizes the relay 34; the yellow light 89 goes out because its circuit at 71 and 72 is interrupted. The green light 85 for the ^ -strasse and the red light 86 for the .B-Strasse light up when current flows through the contacts 71 and 73. In order to light up the green light 83 for the B-Straße and the red light 84 for the A-Stra.Be, the contact blades of the switch 106 are placed on the right contacts and the relay 35 is thereby energized. The armature 74 separates from the contact 75 and thereby opens the circuit for the yellow light 89. By the installation of the armature 74 on the contact 76, the green light 83 for the B-street and the red light 84 for the ^ -street light up on.

The circuit is arranged so that the

yellow light illuminates and all other signal lights are extinguished, either by closing switch 102 (in Fig. 2) or by energizing the two wires F and H leading to the fire brigade. This measure has been taken in order to be able to intervene in an emergency from the monitoring switchboard at the intersection or from a remote location. Each of the two measures mentioned causes the relay 36 to be excited. As a result, the contact relationship between the contacts 100 and 101 as well as 98 and 99 is broken. The relays 34 and 35 are de-energized as a result; armature 71 makes contact with 72 and armature 74 makes contact with 75. The yellow light will illuminate, all other signals will be prevented from illuminating unless you intervene manually in the manner indicated above.

The power source can be of any type.

It has not been shown in the drawings. Only the wires that lead to it are labeled A, C.

The circuit is arranged so that when the right of way is a road through the working of the 30 second relay and not the working of the io second relay is taken, the relay that goes through the sleepers in the street that is straight yours Loses right of way, is excited, that is the relay 26 for the ^! - street or the relay 27 for the B-street, is not de-energized as in the case when the right of way is through the IO second relay is removed, but on the contrary, what remains excited is that the right of way on this road will be returned immediately after a yellow period, which follows the handover through the other street. The arrangement is therefore made in this way because then, 'when the right of way through the work of the 30-second Relay is transmitted to a vehicle that ■ · has affected a threshold in the road that loses her right of way, has not had his full 10-second segment available has to cover the distance between the threshold and the crossing point and to cross the crossing point. Thus it can be between the threshold and the The crossing point can be easily stopped by the red light. This circuit creates the possibility of having the right of way at the earliest allowable moment this car is granted without a threshold in the street on which the vehicle is located, must be particularly influenced. "

This effect is based on the ^ 4 street the following way to get: The working of the 30 second relay 28 to shut off the Relay 32 does not de-energize relay 26, since this relay has current through it Contacts 59 and 61 is supplied. However, if the right of way is through the io-second relay 30 is transmitted, then the armature 59 moves away from the contact 61, and that Relay 26 is de-energized. Where in the above representation there is a change in the switch position is specified to produce a change in the effect on the signaling devices associated with the Traffic-affected facilities ■ work on ^ 4-Strasse, and where else another change in switch position is specified to make the same change in Effect of the signaling means to cause, in connection with the from Traffic-affected facilities in the B-street work, it is clear that the two Changes to the switch positions can be carried out at the same time. To this Way is said change in the effect on the signaling means by the dated Traffic-affected facilities in both or in each street.
