[0001] The present invention relates to a module of a modular traffic divider and to a modular
traffic divider comprising at least one of said modules.
[0002] A very popular kind of traffic dividers in roads and highways is used in the carriageway
between two opposite lanes to separate lanes and increase safety, preventing a vehicle
from invading the opposite lane.
[0003] Examples of this kind of traffic dividers, which are relatively modern, are reinforced
concrete traffic dividers, often marketed with the name of "new-jersey", which are
composed of a plurality of prefabricated modules interconnected by a modular fixing
system and often mounted to separate the two lanes of the highway.
[0004] In spite of being very functional as separation element between the lanes, these
traffic dividers are impaired by a drawback, which is especially related to their
limited vertical volume.
[0005] While this is done, on one side, to reduce the total weight of each module, thus
limiting the fabrication costs and simplifying installation, on the other side this
requires the use of additional measures to reduce glare of users driving along the
highway in one direction caused by the main headlights of the vehicles traveling in
the opposite direction.
[0006] In view of the above, these traffic dividers are often combined with high hedges
to prevent the aforesaid glare.
[0007] The application of hedges to the known types of traffic dividers, however, involves
an initial installation cost followed by the need to maintain said hedges, which occupy
a valuable space without any other advantage than preventing the undesired glare of
users.
[0008] JP 2002 322617 discloses a module comprising two solar panels above the module that can be tilted
with different angles.
[0009] KR 101 027 119 discloses a traffic divider module comprising only one solar panel recessed into
the module.
[0010] CN 201 224 873 discloses a traffic divider module provided with solar panels externally provided
on it.
[0011] The present invention intends to solve the drawbacks of the prior art by providing
a multi-use modular traffic divider that can prevent glare, and is simple to install
and maintain, while offering additional advantages and making the most of space.
[0012] Such a purpose is reached by a traffic divider according to the first attached claim.
[0013] Additional advantageous characteristics are the object of the attached subclaims,
which are an integral part of this document.
[0014] The present invention is based on the idea of providing each module of the modular
traffic divider with one or more solar panels, in such manner to use the space taken
by the traffic divider to produce electrical energy that can be used by the module
or transmitted to other utilities (other modules, street signs, storage batteries,
lighting devices or the like) by means of an electrical connection between a module
and the adjacent one.
[0015] The module of a modular traffic divider according to the invention comprises a base
unit adapted to be placed on the ground, said base unit being provided with a housing
groove open towards the top, and at least two solar panels disposed facing each other
inside said housing groove of the base unit.
[0016] The invention will become clearer following to a detailed description of the enclosed
drawings, which illustrate an embodiment, wherein:
- figure 1 is a module of a traffic divider according to the present invention; and
- figure 2 is an electrical diagram of the traffic dividers of Fig. 1.
[0017] Fig. 1 shows a module (10) of a traffic divider according to the present invention.
[0018] More specifically, Fig. 1 shows a single traffic divider module (10) that, in its
operating condition, is adapted to be mounted in adjacent position and connected to
other similar modules (10), in such manner to form a traffic divider with extension
and direction (either rectilinear or curved) according to the street where it is mounted.
[0019] The traffic divider module (10) comprises a base unit (20) adapted to be positioned
on the ground and provided with structural resistance in order to prevent a vehicle
involuntarily hitting the traffic divider module from breaking through it and passing
to the opposite lane.
[0020] For example, the base unit (20) is made of concrete, reinforced concrete, steel and
the like, and can be optionally provided with water tanks to dampen impacts with vehicles.
[0021] The module (1) comprises two solar panels (3).
[0022] The solar panels (3) are electrically connected one with another and/or with an electrical
socket, such as a bipolar socket (4) installed at the front and/or at the back of
the module, in such manner to place two modules (10) side by side and connect them
electrically.
[0023] Such an electrical connection can be made in series or, more preferably, in parallel,
as shown for example in the electrical diagram of Fig. 2.
[0024] In this diagram each panel is connected to two electrical lines (L1) and (L2) running
in the module (10); one line for positive (L1) and one line for negative (L2). However,
the latter can be clearly omitted, by ground-connecting the negative pole of each
panel (3). In such a case the socket (4) is simplified and can be of unipolar type.
[0025] The electrical energy produced by the panels (3) can be transferred to a storage
battery, for example by means of lines (L1, L2) or used directly by the module (10).
The module (10) can comprise a street sign (6) that is advantageously of back-lit
type, for example LED.
[0026] In such a case, given the very low energy absorption of LEDs, LEDs can be powered
in continuous, by connecting them directly to the panels (3) or electrical lines (L1,L2)
in order to improve the visibility of the signal (6).
[0027] Alternatively or in combination the module (1) is provided with a luminous signaler
(5), such as a strip with light sources, for example LEDs, which are powered by the
energy produce by the panels (3). The luminous signaler (5) makes the traffic divider
more visible and improves the safety conditions of the street where it is mounted.
[0028] The panels (3) are mounted under the top of the base unit (20).
[0029] The base unit (20) is provided with a housing groove (70) wherein two solar panels
(3) are mounted, one in front of the other. The housing groove (70) has a V cross
section, on the internal walls of which solar panels (3) are mounted, in such manner
to be disposed one in front of the other, in oblique position and along the sides
of an isosceles triangle with downward tip.
[0030] The groove (70) opens above the base unit (20) with upward opening.
[0031] In such a case, the exposure of the panels (3) to sunlight depends on the opening
angle at the vertex of the "V" of the groove (70), which should therefore be sufficiently
large; suitable values of said angle may be determined by an expert of the art without
any inventive effort when the installation position and place of the traffic divider
is determined, together with its exposure with respect to the sun.
[0032] Said traffic divider (10) is characterized by simplified maintenance and improved
protection of panels (3).
[0033] A transparent protective sheet (80) is provided above the panels (3), closing the
groove (70) and preventing the exposed surface of the panels from being subject to
impacts (for instance, small stones or debris launched by passing vehicles).
[0034] In the example shown, the sheet (80) is horizontal and extends, like the groove (70),
substantially for the entire extension of the module (10), being possibly provided
with additional transparent vertical end walls.
[0035] Moreover, in case of an impact of the vehicle against the traffic divider (10), fragments
of the panels damaged by the impact are contained inside the groove (70) closed by
the sheet (80), thus preventing said debris from being dispersed on the carriageway.
[0036] Also the accumulation of smog or dirt can be eliminated easily; in fact, smog or
dirt will only deposit on the sheet (80) and not directly on the surface of the panels
(3), which has a considerably larger area.
[0037] On the module (10) the solar panels (3) substantially extend for the same length
as the corresponding base unit (20) in such manner to make the most of the useful
surface. Variants are provided, wherein said length if covered by multiple adjacent
solar panels, as well as other variations wherein the solar panels (3) only extend
for part of total length. Other variants of the general idea as described above are
also possible, which are all to be considered as an integral part of the present invention.
[0038] According to a preferred embodiment, the traffic divider modules are provided with
sensors that are able to detect the speed of the vehicles traveling along the carriageway.
Because of said sensors, each module can detect the slowing down of vehicles caused
by traffic jams or accidents. In such a case, the traffic divider modules situated
upstream said slowing down - with respect to the traveling direction of the lane where
vehicles are slowing down - can be activated to inform the users of vehicles on the
lane through said street signs (6). The signals emitted by said sensors can be processed
by a remote operator or by a management and control unit able to automate said activations
of street signals (6).
