    Installation of road signs
    The invention relates to a road signaling installation, and to a method for controlling an installation of this type.
    Such facilities are used to regulate vehicle traffic on traffic lanes.
    In particular, signaling installations almost always equip road crossroads. There, roadways, each organized in one or more traffic lanes, cross each other in a common area, the crossing itself. This common area must be capable of being crossed in an organized manner by vehicles from adjacent lanes.
    To organize this crossing, it is customary to install at these intersections a switchable signaling, generally in the form of one or more multicolored lights, each attached to the common area and to one or more respective traffic lanes. Depending on the color of the light, the common area is authorized or prohibited for vehicles on the corresponding lanes. The switching of the lights is controlled sequentially and in a coordinated manner by a PLC, generally common to the lights of the installation.
    It is known to adapt, in a sequence, the switching periods of the various lights of an installation in order to make traffic more fluid. The lights attached to the busiest traffic lanes can, for example, be ordered with reduced blackout periods compared to the lights attached to adjacent less traveled lanes. We thus balance the queues that can
    BE2017 / 0159 train on the various traffic lanes, upstream of the crossing area. Thus it is known, to a certain extent at least, to adapt a crossing speed at the crossroads as a function of frequentation of the adjacent roadways.
    For public transport vehicles, such as buses or trams for example, this way of balancing traffic between the different lanes of a crossroads or the like is not satisfactory. In particular to encourage the use of public transport, we seek to have their vehicles have privileged access to the common area.
    To do this, one method consists in reserving for these vehicles a traffic lane on at least some of the intersecting roadways, at least near the common area to be crossed. This negatively impacts other vehicles in that the queues on the non-reserved lanes are generally lengthened.
    Another method, which can be implemented in conjunction with the previous one, consists in modifying the switching period of a light in a sequence when a public transport vehicle is in the immediate vicinity of the light. In practice, this has a fairly limited effect. When traffic is fluid, the gain is quite low for the public transport vehicle. When the traffic is congested, the switching should be delayed so significantly that all of the traffic would be negatively impacted.
    We are still looking to this day for a road sign installation which effectively promotes the crossing of public transport vehicles while limiting the impact on the circulation of other vehicles.
    The proposed installation includes a first switchable signaling system, attached to a crossing zone and to the
    BE2017 / 0159 minus an adjacent vehicle traffic lane. It also includes a second switchable signaling system, attached to a portion of said traffic lane upstream from the crossing area. It also comprises a controller arranged to react to an approach message from a vehicle of a defined type by commanding a switching sequence for the second signaling in which this second signaling prohibits the upstream portion of the taxiway for vehicles of 'a different type over at least one period of the switching sequence.
    The proposed installation makes it possible to reserve the upstream area for vehicles of the defined type, in particular for public transport vehicles. This reservation is made dynamically, when the approach of a vehicle of the defined type is detected. In the absence of such detection, the upstream area can be used by all vehicles, regardless of type. As a result, vehicles of the defined type have privileged access to the crossing area with minimal impact on the movement of vehicles of a different type.
    The proposed installation can be easily implemented on an existing multi-color fire type installation, without substantial modification of the latter.
    A method of controlling a road signaling installation is also proposed, comprising a first switchable signaling attached to a crossing zone and at least one adjacent vehicle traffic lane and a second switchable signaling attached to a portion of said traffic lane. upstream of the crossing area. The process includes the following steps:
    - receive an approach message from a vehicle of a defined type;
    - command a switching sequence for the second signaling in which this second signaling prohibits the upstream portion of the traffic lane for vehicles of a different type over at least one period of the switching sequence.

    • Figure 2 shows a diagram of a traffic intersection equipped with another installation according to the invention;
    • Figure 3 shows a flowchart illustrating the operation of an automatic control system of an installation according to the invention;
    • Figure 4 shows a diagram of a signaling element for an installation according to the invention; and • Figure 5 shows a diagram of another signaling element for an installation according to the invention.
    The attached drawings contain elements of a certain character. They can not only serve to complete the invention, but also contribute to its definition, if necessary.
    Reference is made to Figure 1.
    It shows a road junction with a signaling installation 1 arranged to regulate traffic at this junction.
    The intersection in this example comprises a portion of a first carriageway 3 and a portion of a second carriageway 5 which intersect each other in an intersection zone 7, hatched in FIG. 1.
    BE2017 / 0159
    A first sidewalk, on the right in FIG. 1, or right sidewalk 9, borders the first carriageway 3 on one side thereof. A second sidewalk, on the left in FIG. 1, or left sidewalk 11, borders the first carriageway 3 on the side thereof opposite the right sidewalk 9.
    A first traffic lane, in the direction of the intersection zone 7, or right lane 13, is organized on the first carriageway 3, at least on a part of it adjacent to the intersection zone 7. The first Pavement 3 also supports a second traffic lane, towards the intersection zone 7, or left lane 15, adjacent to the right lane 13, at least near the intersection zone 7.
    A separation between the right lane 13 and the left lane 15 can be materialized at least partially by a marking on the ground 17, for example a broken line.
    The installation 1 comprises a first switchable signaling 100, attached to the first roadway 3 and to the intersection zone 7. Depending on its switching state, the first signaling 100 indicates to the vehicles on the first roadway 3 a ban or authorization to '' access intersection area 7.
    Signaling 100 is general in scope. Signaling 100 targets vehicles on the first roadway 3 without distinction of type.
    The first signal 100 here comprises a right light 102 and a left light 104, arranged substantially one opposite the other, respectively to the right and to the left of the first carriageway 1, and an effect line 106 associated with these lights. The effect line 106 can be materialized by a marking on the ground or be virtual, for example directly above the right 102 and left 104 lights.
    Each of the right light 102 and the left light 104 is attached to the right lane 13 and to the left lane 15, as well as to the intersection zone 7. The right light 102 and the left light 104 indistinctly signal vehicles of the right lane 13 and those of the
    BE2017 / 0159 left lane 15 which are close to the effect line 106 an authorization or a prohibition to access the intersection zone
    7. As a variant, each of the right light 102 and the left light 104 is respectively attached to one of the right lane 13 and of the left lane 15 and is used for signaling to vehicles of this lane.
    A first control automaton 200 is programmed to control the main signaling 100, according to switching sequences in which the main signaling 100 authorizes and prohibits the intersection zone 7 for vehicles of the first roadway 3 and those of the second roadway 5 in a coordinated manner. The first automaton 200 can be housed in a control cabinet 202, for example located on the right sidewalk 9, near the right light 102.
    In particular, the right light 102 and the left light 104 are controlled by the first controller 200 according to switching sequences which are here identical. These sequences can also differ from each other, in particular when the right light 102 and the left light 104 are attached to the right lanes 13 and left lanes 15 respectively.
    The installation 1 also comprises a second switchable signaling 300. The second signaling 300 is attached to a portion of the right lane 13 located upstream of the intersection zone 7, or upstream portion 302. The upstream portion 302 extends from an effect line 301 of the second signaling 300 to the effect line 106 of the first signaling 100. Here, the upstream portion 302 comprises a single section 303. For example, the section 303 extends over several tens of meters in length, for example over a length L303 of approximately 50 meters.
    According to its switching state, the second signaling 300 indicates a prohibition or an authorization to access the upstream portion 302. The second signaling 300 can be of specific scope. The second signaling 300 can target vehicles of a
    BE2017 / 0159 first defined type, for example vehicles other than public transport vehicles, or TC vehicles.
    The installation 1 comprises a second automaton 305 which controls the second signaling 300. The second automaton 305 can be housed near the first automaton 200.
    The second signaling 300 comprises at least one switchable signaling element of a first type, or first signaling element. The first signaling element or elements are controlled jointly and sequentially by the second automaton 305 to indicate an authorization or a prohibition to access vehicles upstream 302 on the right lane of the first type 13. In particular, the second signaling 300 comprises at least one respective first signaling element for each section 303 of the upstream zone 302.
    Each first signaling element is of the so-called “vertical” type. At least one first signaling element is disposed near an end zone of each section 303 remote from the intersection zone 7.
    The first signaling element here takes the form of a light panel of a first type, or first light panel 304. This first light panel 304 is arranged in the vicinity of an upstream portion end 302 remote from the intersection zone 7, upstream of this upstream portion 302.
    The first light panel 304 can be switched sequentially by the second automaton 305 between an on state where it indicates an authorization to access a section 303 of the upstream area 302 for vehicles of a second defined type, and an off state where it indicates an authorization to access this section 303 to the vehicles of the right lane 13, without distinction of type.
    BE2017 / 0159
    The first panel 304 is arranged to signal, in the lit state, a reservation of a section 303 of the upstream zone 302 to vehicles of the second type, for example TC vehicles.
    Reference is made to FIG. 4. It shows an exemplary embodiment of a light panel 3040 for use, for example, as the first light panel 304. The light panel 3040 can have a dark background 3042, a first light pictogram 3044, to left, symbolizing the left lane 15 and a second light pictogram 3046 symbolizing the right lane 13.
    The first pictogram 3044 represents a first arrow. The second pictogram represents an arrow crossed out with a symbolic representation of a vehicle of the second type, here a bus.
    The light panel 3040 can have an on state, where the first pictogram 3044 and the second pictogram 3046 are lit, and an off state, where only the dark background is distinguished 3042.
    Reference is made to Figure 1.
    The second signaling 300 further comprises at least one switchable signaling element of a second type, or second signaling element. The second signaling element (s) can be controlled by the second automaton 305 in a coordinated manner with the first elements so as to indicate to vehicles of the first type a prohibition or authorization to access the upstream zone 302 from a portion of the lane left 15 adjacent to this upstream zone 302.
    In particular, the second signaling 300 can comprise at least one respective second signaling element for each section 303 of the upstream zone 302.
    BE2017 / 0159
    This second signaling element is here of the so-called "horizontal" type. Each second signaling element preferably comprises a signaling on the ground, on a part of the roadway corresponding to a section 303 of the upstream zone 302.
    The second signaling element can be produced in the form of at least one light strip 308 which extends in the longitudinal direction of a section 303 of the upstream zone 302. The light strip 308 can extend substantially over the entire length of this section 303. This strip can be crossed by vehicles traveling on the upstream area 302.
    The light strip 308 can be controlled by the second automaton 305 sequentially between an off state where it indicates an authorization to access the section 303 of the upstream zone 302 to the vehicles of the second track 15, without distinction of type, and an on state where it indicates a prohibition to access this section 303, in particular to vehicles of the first type of the second track 15.
    The light strip 308 can be produced in the form of a sill 310 in leveled concrete and a plurality of light sources in the form of light studs 312, typically red or orange, integrated in this sill 310. The studs 312 are for example of the type known under the reference LED TBT ECO-845. They are regularly distributed along the sill 310, with a P312 pitch of 2 meters for example. The TBT network 314 can be buried in pavement 3, for example at a depth of approximately 7 to 10 centimeters.
    The pads 312 are here connected to each other in a very low voltage electrical current network, or TBT network 314. The TBT network 314 can be produced for example with wire conductors of 2.5 square millimeters in cross section. The TBT network 314 is buried in the first carriageway 3, for example about 40 centimeters deep.
    BE2017 / 0159
    The TBT network 314 can be connected to one or more current transformers 316, connected to each other through a low voltage electrical network, or LV network 318. The BT network 318 can be buried, for example at about 60 centimeters depth. The transformers 316 are here housed in stretch manholes 320 regularly arranged along the straight sidewalk 9, for example every 10 meters approximately.
    The light strip 308 sequentially indicates a prohibition to access the upstream area 302 from an adjacent part of the left lane 15 in a manner equivalent to a solid line which would separate the right lane 13 from the left lane 15 in this upstream area 302 and an authorization to access this upstream area 302 equivalent to a broken line.
    The light strip 308 can be placed in a middle zone of the right channel 13 as here. In addition or as a replacement, the second signaling element is produced in the form of a light strip of the type of light strip 308 and arranged on the roadway 3 so as to separate the right lane 13 from the left lane 15 on a respective section 303 of the upstream zone 302. In addition or as a replacement, the second signaling element further comprises a reflective strip 309A, disposed on the roadway 3 so as to separate the right lane 13 and the left lane 15. This strip can be crossed by vehicles traveling on the upstream zone 302. This reflecting strip 309A can be replaced by the light strip 308 or a similar light strip.
    Here for example, the reflective strip 309A comprises a plurality of reflective pads 322 arranged aligned with each other. The pads 322 are regularly distributed, according to a pitch P322, for example of about one meter. In addition, a similar alignment 322 can be arranged between the light strip 308 and the right sidewalk 9, with a pitch P324 identical for example.
    BE2017 / 0159
    As a variant to what has just been described, the right lane 13 and the left lane 15 can be separated from one another in the upstream zone 302 by a solid line preventing access to this zone by vehicles from the left lane 15 without distinction of their type. Such a line is part of the second signaling 300. In this case, the light strip 308 can be kept in that it can also be visible from vehicles in the right lane 13. The light strip 308 thus cooperates with the first element signaling to indicate a prohibition or authorization to access the upstream area 302 from the right lane 13.
    Preferably, however, when a strip similar to the light strip 308 equips the upstream area 302, the right lane 13 and the left lane 15 are there separated from each other by a signaling on the ground allowing a crossing, for example by the light strip 308 itself. Such signaling authorizes vehicles of the first type present in the upstream zone 302 to free upstream zone 302 by gaining the second lane 15 in a reserved state of the upstream zone 302. In a non-reserved state, such signaling allows access to the upstream area 302 from the left lane 15.
    As an option, the second signaling 300 also comprises at least one switchable signaling element of a third type, or third signaling element. The third signaling element or elements can be switched by the second automatic device 305 so as to dissuade vehicles of the first type from using the upstream zone 302 and / or invite these vehicles to leave this upstream zone 302. In particular, the second signaling 300 may include a respective third signaling element for each section 303 of the upstream area 302.
    This third signaling element can be of vertical and / or horizontal type. The third signaling element may take the form of an auxiliary panel 306 placed close to or,
    BE2017 / 0159 as here, a few tens of meters from the light panel 304, for example at a distance L306 of about 20 meters from the latter.
    Reference is made to FIG. 5 which shows an exemplary embodiment of a light panel 3060 as an example of an auxiliary panel 306. The light panel 3060 comprises a dark background 3062, a first light pictogram 3064 symbolizing the left lane 15 on a left part of the dark background 3062 and a second luminous pictogram 3066 symbolizing the right lane 13 on a right part of the dark background 3062. The first pictogram 3064 represents here an arrow while the second pictogram 3066 represents oblique arrows symbolizing a maneuver drawdown. The auxiliary panel may be at least partly common to the light panel 304. For example, these panels share a support forming the bottom.
    The light panel 3060 can have an on state, where the first pictogram 3064 and the second pictogram 3066 are lit, and an off state, where only the dark background is distinguished 3062.
    Reference is made to Figure 1.
    The second signaling 300 here comprises an auxiliary light strip 309B located in an end zone of the section 303 remote from the intersection zone 7. The auxiliary strip 309B extends across the right lane 13, obliquely. This auxiliary strip 309B can be ordered to invite the vehicles of the right lane 13 to fall back on the left lane 15. This auxiliary light strip can be seen as an embodiment of at least part of a signaling element of the first type in that it can be switched so as to prevent access to the upstream area 302, in particular to vehicles of the first type. This auxiliary light strip 309B can also be seen as an embodiment of at least part of a signaling element of the third type in that it invites vehicles of the first type to fall back onto the left lane 15.
    BE2017 / 0159
    The signaling installation also includes an approach detector attached to the upstream portion 302 and capable of emitting a warning signal when approaching a vehicle of the second type. The approach detector can be placed upstream of the upstream zone 302.
    Here, the approach detector comprises a radiofrequency communication system between vehicles of the second type and the second automaton 305. This system typically comprises a radiofrequency transmitter for use on board vehicles of the second type and a radiofrequency receiver connected to the automaton 200 through a modem.
    The second automaton 305 is arranged so as to command a switching sequence for the second signaling 300 on reception of a detection signal from a vehicle of the second type. This switching sequence includes a reservation period for the upstream zone 302. The reservation duration can correspond to switching sequences for the first signal 100. This makes it possible to adjust the occupation of the upstream zone 302 by the coordinated command of its output by the first signal 100 and its input by the second signal 300.
    Preferably, the second signaling 300 is switched so as to reserve the upstream zone 302 for a period corresponding to at least two switching sequences of the first signaling 100.
    Reference is made to FIG. 2. It shows another signaling installation, analogous to installation 1 of FIG. 1. Identical reference numbers there designate functionally analogous elements.
    The first roadway 3 extends between buildings 330. This first roadway 3 here supports a third
    BE2017 / 0159 traffic 16, adjacent to the second traffic lane 15 and in the opposite direction to the intersection zone 7. A separation between the third lane 16 and the second lane 15 is indicated by a marking on the ground, here a continuous line 18.
    The upstream zone 302 comprises a plurality of sections 303, here a first section 303-1 distant from the crossroads and a last section 302-5 close to this crossroads, as well as a second 303-2, a third 303-3 and a fourth section 303-4 interspersed, in this order, between the first section 303-1 and the last section 303-5. The sections can be spaced from each other by several tens of meters, for example around 70 meters.
    Each section 303 comprises a respective signaling element of the first type, for example a light panel 304 attached to an end zone of this section 303 remote from the intersection area 7. Each section 303 further comprises a respective signaling element of the third type, in particular in the form of at least one light line 309A which extends along this section 303, between the first track 13 and the second track 15.
    Optionally, the second signaling 300 of the installation 1 comprises signaling elements attached to an area of the first track 13 downstream of the intersection area 7, or downstream area 305. In particular, the downstream area 305 is organized in one or more sections equipped analogously to each section 303 of the upstream area 302.
    Each section 303 extends over several tens of meters, in particular about 50 meters. This corresponds to an area of about 400 meters long for the upstream area 302.
    Reference is made to Figure 3.
    It shows the operation of a control automaton for a road signaling installation, for example the automaton
    BE2017 / 0159
    305 of FIG. 1, for a switching sequence of a signaling analogous to the second signaling 300 of FIGS. 1 and 2 for example.
    In an initial step 400, the second signaling is in a switching state such that its upstream portion can be taken by vehicles, without distinction of type. In particular, this upstream portion 302 can be used by vehicles other than TC vehicles. The second signaling is switched to a free mode and / or off.
    The first signaling elements of the upstream area 302 are in a switching state such that they allow access to their respective sections for all vehicles, regardless of type. The light panels 304 are off.
    The second signaling elements of the upstream area 302 are in a switching state where they authorize access to their respective section 303 from the left lane 15. The median light lines 308 or of separation 309A are off.
    The third signaling elements are inactive. The auxiliary panels and / or the auxiliary lines are off.
    In the next step 402, the automaton receives a message signaling that a vehicle of the second type, typically a TC vehicle, is approaching the upstream area 302. This is for example a message sent by this TC vehicle by wave lane and warning of its imminent arrival on the upstream zone 302. The message in question may include an estimated value of approach time, or more generally any data which allow a deduction of an estimated value of approach time , if necessary using what are called approach curves. Such data includes in particular a location indication such as GPS coordinates, or a stop identifier on a line, or even a distance indication.
    BE2017 / 0159
    In the next step 404, the controller reacts to the reception of the approach message by implementing a first subsequence corresponding to a transition period, or first transition sequence.
    In the first transition sequence, the automaton controls the signaling element or elements of the upstream portion 302 so as to dissuade vehicles other than those of the first type, that is to say non-TC vehicles, from using their respective section 303 and / or invite them to leave this section. If necessary, the automaton controls the lighting of the auxiliary panels which invite vehicles other than TC vehicles to leave the right lane 13.
    The second signaling elements can be controlled according to a transient switching state, for example a flashing and / or orange color when it is a case of multicolored devices. If necessary, the light strips 308 flash.
    The first transition sequence ends with a command from the PLC switching the signaling elements to a reservation mode.
    In this transition sequence, the controller can control all of the signaling elements in the upstream area simultaneously. The signaling elements of all the sections start this sequence simultaneously and end it in the same way.
    As a variant, the PLC can control the signaling elements by section. For example, the controller first switches the elements of the first section 303-1 into transient mode, then those of the next section and so on. Similarly, the controller first switches the elements of the first segment to reservation mode, then those of the next segment and so on.
    BE2017 / 0159
    The switching of signaling elements between transient mode and reservation mode can result from the expiration of a time period. This period may possibly be different for each section. The duration of this period can be estimated, using the approach curves. As a variant, the switching results from the reception of a second approach message. Such a message can correspond to the reception of a message from a particular vehicle, in particular TC, or result from the detection of the approach of a vehicle of this type.
    Preferably, the switching to transient mode is accompanied by a command of the first signaling in a mode which privileges the authorization to access the intersection zone 7 to the vehicles of the right lane 13, without distinction of type. . Such a mode is sometimes referred to as "green priority" in the art.
    In the next step 406, the second signaling is in a switching state which prohibits the upstream portion 302 from vehicles other than vehicles of the second type. The second signaling is in reservation mode. The light panels 304 and / or light strips 308 are on.
    In the next step 408, the automaton receives an acknowledgment message signaling that the TC vehicle has passed the intersection zone 7. This message can be emitted by the TC vehicle itself or result from a detection of the presence of this vehicle downstream of the intersection zone 7.
    The reception step 408 is followed by a step 410 in which the automaton controls the signaling elements of the upstream area 302 according to a second subsequence corresponding to a transition period, or second transition sequence. For example, the automaton controls the extinction of the median light bands 308 and / or of separation 309 and / or of the light panels 304 as the vehicle TC progresses towards the intersection zone 7. This
    BE2017 / 0159 progression can be estimated from the approach curves in particular.
    The second transition sequence ends with a command from the PLC switching the signaling elements into free or off mode. The controller controls the second signaling so that the upstream area 302 is again authorized to all vehicles, regardless of type, as in the initial step 400.
    We have just described a road signaling installation which makes it possible to make the upstream zone 302 a dynamic reservation zone thanks mainly to the second signaling 300 and the first signaling 100 which jointly regulate the access to the upstream zone 302 and the exit from this zone 302 respectively.
    The invention is not limited to the embodiment described above, by way of example only. In particular :
    - The invention is not limited to an installation controlling access to an intersection zone but applies when it is a question of regulating by crossing a first signal the crossing of a traffic zone.
    - The invention is not limited to a first signaling comprising colored lights but applies to any signaling which can be switched so as to indicate a prohibition or an authorization to access a crossing zone, for example comprising a or several barriers, light signaling on the ground, or other.
    - The invention applies in the same way to several installations of the type described above, arranged on successive circulation routes and controlled in an organized manner
    - The crossing area is not limited to a crossing with another roadway.
    BE2017 / 0159
    - The second signaling controller function can be performed by the first signaling controller.
    - Vehicle detection loops for use with the first signal 100 and / or the second signal 300 may be provided near the effect line 106 of the first signal. These loops can be buried in pavement 3, for example at a depth of 7 to 10 centimeters.
    - A light strip 308 has been described as an example of traffic lights 13. Other embodiments of such traffic signs can be envisaged.
    - A light strip 308 has been described that is turned off to allow access to the upstream area 302 and that is turned on to prevent access. If necessary, this strip flashes during a transition period dissuading access to this zone or prompting to leave it. More generally, such indications can be signaled by the command of the control automaton so as to modify at least some of the light characteristics of the strip 308, and more generally of any light markup. Such characteristics include for example the color of the light emitted, its intensity, a flashing frequency or an off / on state.
