It should be noted that the embodiments and drawings described below exemplify a part of the embodiments of the present invention, and are not used for the purpose of limiting to these configurations, and do not depart from the gist of the present invention. Can be changed as appropriate.

  With reference to FIG. 1 thru | or FIG. 4, the gaze guidance mark apparatus 10 of the state installed in the sound insulation wall 4 of a highway, for example is demonstrated. FIG. 1 is a schematic diagram illustrating a speed guidance system 1 that emits light from the line-of-sight guidance device 10 according to the embodiment to induce speed. Drawing 2 is a figure which looked at the state where line-of-sight guidance mark device 10 of an embodiment was installed in sound insulation wall 4 of an expressway from the front. Drawing 3 is a figure which looked at the state where line-of-sight guidance mark device 10 of an embodiment was installed in sound insulation wall 4 of a highway from the side. FIG. 4 is an enlarged view of a portion A in FIG. 3 of the embodiment.

  For example, FIG. 1 is provided in a section where the upward gradient of the road R is + 0.8%, and a plurality of line-of-sight guidance devices 10 are provided along the road R. The light emitting unit 20 of the line-of-sight guidance device 10 is a speed guidance system 1 that sequentially lights at a predetermined speed and guides the speed of the vehicle to a predetermined speed for the driver.

  As shown in FIGS. 1 to 4, first, an installation state of the line-of-sight guidance device 10 will be described. For example, on a highway through which the vehicle D passes at high speed, a sound insulation wall 4 for reducing noise is provided in the vicinity of the road R through which the vehicle D passes. A dome-shaped sound absorbing cover 5 is provided on the sound insulating wall 4. The line-of-sight guidance device 10 is installed on the sound insulation wall 4 at a position of about 1400 mm to 2000 mm upward from the road R and with a mounting interval of 6000 mm in the traveling direction of the vehicle D.

  The sound insulation wall 4 has a thin sound insulation plate 6 having a size of 1500 mm in the longitudinal direction fixed to the support column by fixing bolts 8 in the vertical direction. These sound insulation plates 6 prevent noise outside the highway when the vehicle travels. The line-of-sight guidance device 10 is fixed by being fastened together with a fixing bolt 8 for attaching the sound insulating plate 6 to the sound insulating wall 4.

  As shown in FIGS. 3 and 4, the L-shaped concrete wall 9 provided in the vicinity of the road R through which the vehicle D passes is provided with a sound insulating wall 4 that stands up vertically, and a triangle with a lower end cut out at the boundary. A support metal plate 7 having a shape is provided. The support sheet metal 7 protrudes to the outside as a part of a column for fixing the sound insulation plate 6 of the concrete wall 9. Further, the support sheet metal 7 is provided with a support sheet metal through hole 42 having a lower end cut out in an arc shape. The support plate metal through-hole 42 is wound with a fall prevention wire 42 so that the fixing bolt 8 fastening the line-of-sight guide device 10 is removed and the line-of-sight guide device 10 does not enter the road R side even if it falls. .

  In addition, a tubular wiring duct 3 is installed horizontally along the road R in the vicinity of the support sheet metal 7. In the wiring duct 3, a power line 27, a connecting wiring 24, and a control wiring are laid. The wiring duct 3 is fixed to the support metal plate 7 by being wound by a metal or resin fixing band 43 through the support metal plate through hole 42.

  Next, the gaze guidance apparatus 10 will be described with reference to FIGS. FIG. 5 is a perspective view showing the line-of-sight guidance device 10 of the embodiment. FIG. 6 is a rear view illustrating the line-of-sight guidance device 10 according to the embodiment. FIG. 7 is a plan view of a state in which the line-of-sight guidance device 10 of the embodiment is installed on the sound insulating wall 4 of the highway as viewed from above.

  The line-of-sight guidance device 10 is provided with a corrugated sheet metal 11 having a predetermined angle on the surface viewed forward from the driver of the vehicle D. The corrugated metal plate 11 is made of metallic aluminum with little corrosion. Further, the surface of the corrugated sheet metal 11 is subjected to an acrylic resin-based baking coating which is non-reflective such as white in order to reduce reflection of light from the headlight of the vehicle to the driver and reflection of sunlight. Yes. Therefore, the reflection of light by the mirror surface of the surface made of metal such as aluminum or stainless steel is prevented, and the safety as well as the corrosion resistance to the driver is ensured. In addition, the light emitting unit 20 is easily seen by reducing reflection.

  As shown in FIG. 7, the corrugated sheet metal 11 is provided with a predetermined angle β so that the center of the viewing angle of the light emitting element 21 (LED) of the light emitting unit 20 faces the road R or the driver in accordance with road conditions. The light emitting element 21 is fixed by the mounting portion 30. In the present embodiment, the best predetermined angle β of the mounting portion 30 is set to 45 degrees, but the angle β can be appropriately changed in order to maintain optimum visibility according to road conditions. An LED insertion hole 22 is provided on the driver side of the mounting portion 30 as a circular through hole. The LED insertion hole 22 is configured such that the LED 21 can be inserted. As shown in FIG. 7, a part of the LED 21 protrudes from the triangular apex of the mounting portion 30 toward the driver from the LED insertion hole 22. . Therefore, even if the attachment location is a curve or the like, the LED 21 is easy to see. Further, by providing the light emitting point C of the LED 21 closer to the road than the mounting portion 30, the brightness of the LED 21 can be made visible to the driver as it is. Further, the corrugated attachment portion 30 provided with a predetermined angle β can be strengthened by raising the sheet metal in a triangular shape, and has a structure that is resistant to impacts such as stepping stones. Further, by raising the mounting portion 30 at an angle β, it is easy for the driver to visually recognize the line-of-sight guide device 10 attached to the sound insulation wall 4 on the side road parallel to the road and spaced from the road R. However, the gaze guidance apparatus 10 can be easily attached.

  The light emitting unit 20 includes 15 LEDs 21 arranged above and below the corrugated sheet metal 11 in one row at intervals of 28 mm, and the LEDs 21 arranged in the one row are provided with a predetermined interval α of 57 mm forward and backward with respect to the driver. The LEDs 21 are arranged in rows. In this way, the light emitting unit 20 is made vertically long so that it can be easily seen even from a high position from a large truck. Further, by arranging two rows, the light emitting section 20 is wide and easy to see even if the speed increases. Since the light emitting unit 20 has a height position from the road R where the light emitting unit 20 is installed is also about 1400 mm to 2000 mm, since it is the position of the driver's line of sight, it acts on the driver's perception and leads to a desired speed. . Furthermore, by separating the light emitting unit 20 in two rows forward and backward with a predetermined interval α, it can be visually recognized as having a predetermined width rather than a narrow width even from a distance. Therefore, it is easy for the driver to recognize. In this way, the line-of-sight guidance indicator device 10 looks like a single vertically long line from the driver's perspective, and acts on the driver's perception to the driver due to the lighting speed of the line-of-sight guidance indicator device 10. The speed is induced. Also, by providing two rows of vertically arranged LEDs, it can be installed without worrying about the mounting angle as compared to a single row of cylindrical shapes, etc., and the light emitting unit 20 can be seen from anywhere. .

  The LED 21 employs a bullet-type high-intensity light-emitting diode, and has a viewing angle of 30 degrees, an emission color of green, and a wavelength in the range of 520 to 575 nm, and most preferably 525 nm. The luminance ranges from 12000 mcd to 21000 mcd, and this luminance can be changed by a current value or the like or pulse width modulation. Further, since this luminescent color is a color that is not stimulating for eyes such as red, a color that is naturally induced by the driver and has a high luminance is adopted. Although an LED is employed as the light emitting element 21 of the light emitting unit 20, a discharge tube, an organic EL, a semiconductor laser, or the like can be considered as another light emitting element. In addition, although LED21 protruded and arrange | positioned vertically, it was also considered that it is set as the light emission part arrange | positioned vertically using a light-guide plate. In particular, the number, shape, and emission color of the LEDs 21 are not limited to those in the present embodiment, and can be appropriately changed according to road conditions.

  The line-of-sight guidance device 10 electrically connects LED wirings 23 that are individually connected to the LEDs 21. Further, the LED wiring 23 is further provided with a connection wiring 24 provided by electrically concentrating the LED wirings 23 so that the two rows of light emitting units 20 provided in the housing 12 can be turned on simultaneously.

  Fixing bolts 13 are attached to the four corners of the corrugated sheet metal 11 so as to be combined with the housing 12 on the back surface. In addition, a wire through hole 14 is provided as a through hole through which the above-described fall prevention wire 41 is passed in the lower center of the corrugated sheet metal 11. The through hole 14 having the same size is provided in the same position in the housing 12, and the wire through hole 14 is passed through the fall prevention wire 41 and the support sheet metal through hole 42 laid on the sound insulating wall 4. As a result, it is prevented from falling on the road R and does not become an obstacle to the highway.

  A box-shaped housing 12 formed of a metal such as aluminum or stainless steel with one side open on the back surface is combined with the corrugated sheet metal 11 by a flange 18 protruding from the side surface to both sides. Moreover, the attachment fixing piece 15 which was biased to one piece of the housing | casing 12 and protruded in the L shape is attached to two places by spot welding. The attachment fixing piece 15 is provided with a cutout portion 16 in which a part of the protruding piece is cut out and opened downward. The line-of-sight guidance device 10 is attached by inserting a fixing bolt 8 for attaching the sound insulating plate 6 to the sound insulating wall 4 into the cutout portion 16 and fastening them together. Therefore, it is not necessary to consider a new attachment method or to provide a fixture on the sound insulation wall 4 side. Therefore, the line-of-sight guidance device 10 can be mounted and fixed inexpensively and easily without selecting the mounting position, and can be firmly fixed.

  The housing 12 is provided with two through-hole wiring fixing holes 17 that can pass a binding band or the like in the vicinity of the lower wire through hole 14. The wiring fixing hole 17 is a hole for fixing the connection wiring 24 to the housing 12 through a binding band or the like by these two holes.

The casing 12 is provided with a bent piece 19 formed by bending a metal piece as a lid on the upper side so that rain, foreign matter and the like do not enter as much as possible.
In this embodiment, the corrugated sheet metal 11 and the housing 12 are made of metal, but may be made of resin, concrete or the like as long as it is a durable or weather resistant material. Further, the installation location is not limited to the sound insulation plate 6 and can be installed on a concrete wall surface, a fence side surface, an independent support column, or the like according to road conditions. Moreover, it will not be specifically limited if it is the installation of the vicinity of roads, such as not only the sound insulation wall 4 but a tunnel and a bridge.

  Next, the control of the visual guidance system 10 will be described with reference to FIG. 1 or FIG. FIG. 8 is a block diagram illustrating an electrical connection of the line-of-sight guidance device 10 according to the embodiment. In the speed guidance system 1, one unit is constituted by four gaze guidance mark devices 10 (10a, 10b, 10c, 10d). The unit of visual guidance apparatus 10 (10a, 10b, 10c, 10d) is electrically connected to the control device 25 by a connecting wire 24.

  The control device 25 is provided with an on / off switch for controlling on / off of the power supply to the visual guidance system 10, and in one unit, one of the four visual guidance systems 10 is turned on and the remaining three lights are used. Control to turn off is performed. Since the interval between the one line-of-sight guidance device 10 is 6000 mm, one unit has an interval of 24000 mm, and the lighting interval is an interval of 24000 mm.

The lighting is switched in the order of 10a, 10b, 10c, and 10d in the traveling direction of the vehicle D, and the lighting speed from 10a to 10b is controlled at a speed of 60 km / h to 70 km / h. These are repeated at the same speed (60 km / h to 70 km / h), from 10b to 10c, from 10c to 10d, from 10b to 10a. Therefore, the line of sight is also guided from the driver at a speed of 60 km / h to 70 km / h. These gaze guidance mark devices 10 are installed on the left lane side where traffic congestion first occurs, particularly in the 600 m section near the beginning of the upward gradient section (gradient of about + 0.8%) where the traffic congestion occurs. Is directed. As a whole, the speed guidance system 1 has 100 line-of-sight guidance mark devices 10, and 25 units are provided as units.
In this way, the line-of-sight guidance device 10 works on the driver's perception by guiding the line of sight toward the traveling direction of the vehicle D at a speed faster than the speed at which the traffic congestion occurs, thereby accelerating the speed increase of the driver. It is intended to mitigate. In addition to alleviating traffic congestion, the gaze guidance device 10 causes the driver to guide his / her line of sight at a speed slower than the actual speed so as to encourage the driver to perceive speed reduction and to achieve an appropriate speed. Can be kept. These are adjusted to speed to prevent accidents.

The control device 25 adjusts the luminance between bright day and dark night so that the luminance is not stimulating to the eyes of the driver. The brightness of the light emitting unit 20 is adjusted by detecting the environment of the visual guidance apparatus 10. For example, when the daytime luminance is set to 100%, control is performed to lower the nighttime luminance to about 50%. As a method for detecting the environment, a method of directly measuring the illuminance, a method of indirectly measuring the voltage of the power source of the solar panel, or the like can be considered. As a method of adjusting the luminance, a method of adjusting the luminance by adjusting a current value or luminance adjustment by pulse width modulation (PWM method) can be considered.
Although the method for detecting the environment has been described above, a method of adjusting the luminance of the light emitting unit 20 during the day and at night based on time and time by providing a timer without detecting the environment is also conceivable.

Also, AC 100V is supplied to the control device 25 as a power source. The control device 25 is supplied with DC power to the LED 21 by an AC-DC converter. Further, the control device 25 is connected to a short circuit protection device 26 to protect the short circuit from the power supply line 27.
In the present embodiment, the predetermined speed is set to a speed that is faster than the speed of occurrence of traffic congestion or a speed that is slower than the actual speed even when the speed is exceeded, but is not particularly limited, and is desired according to road conditions. You may set it to speed. In addition, the number of units of the line-of-sight guidance device 10 and the number of units that are simultaneously turned on are not limited and can be changed as appropriate. Also, the speed may be controlled to change to a desired speed instead of a constant speed. For example, the lighting speed is increased to eliminate a traffic jam, and the speed is decreased to warn of excessive speed. It is also possible to perform control that varies depending on road conditions. In the present embodiment, lighting is performed in the traveling direction of the vehicle D, but control may be performed so that the lighting is performed in a direction opposite to the traveling direction of the vehicle D depending on road conditions.

The corrugated sheet metal 52 is provided with a light emitting unit mounting plate 52b and a light emitting unit mounting plate 52e which are bent from the mounting plate 52a and maintain a predetermined angle. Further, the corrugated sheet metal 52 is provided with an inclined back plate 52c and a back plate 52f on the back surface of the light emitting unit mounting plate 52b and the light emitting unit mounting plate 52e.

The corrugated sheet metal 52 is provided by inclining the angle θ of the light emitting portion mounting plate 52b, so that the light emitting cover 61 attached to the light emitting portion mounting plate 52b is attached at an angle α to the mounting surface. Yes. Further, by providing the light emitting portion mounting plate 52e with the angle γ inclined, the light emitting cover 61 attached to the light emitting portion mounting plate 52b is attached with the angle γ maintained with respect to the mounting surface. The angle θ is 70 degrees, the angle α is 20 degrees, and the angle γ is 45 degrees. Note that the numerical values of the angle θ, the angle α, and the angle γ are merely examples, and are not particularly limited. By setting these to different angles, it is easy for the driver to see from a plurality of lanes according to road conditions (the angle θ , Angle α, angle γ).
Further, the surface of the corrugated sheet metal 52 is subjected to an acrylic resin-based baking coating that is non-reflective such as white in order to reduce reflection of light from the headlight of the vehicle to the driver and reflection of sunlight. Yes. Therefore, the reflection of light by the mirror surface of the surface made of metal such as aluminum or stainless steel is prevented, and the safety as well as the corrosion resistance to the driver is ensured. In addition, the light emitting unit 60 is made easier to see by reducing reflection.
Further, a wire through hole 54 is provided on the side surface of the corrugated sheet metal 52 as a through hole through which the above-described fall prevention wire 41 (FIG. 4) is passed. The wire through hole 54 prevents an accident from falling onto the road R by passing through the fall prevention wire 41 and the support sheet metal through hole 42 laid on the sound insulating wall 4 so as not to be an obstacle to the highway.

The light emitting unit 60a has 18 light emitting covers 61 arranged vertically on the light emitting unit mounting plate 52b in front of the driver, and behind the light emitting units 60b, c, d, the light emitting units 60b, c, d emit light to the light emitting unit mounting plate 52e. Six covers 61 are arranged vertically, and six sets of the six units 61 are arranged vertically with a space therebetween.
The light emitting section 60a keeps an angle that can be viewed from a distance by arranging a plurality of light emitting covers 61 in a vertical line at the center and making the angle as shallow as α as described above. In addition, the light emitting units 60b, c, and d are arranged with the light emitting covers 61 attached to the light emitting unit mounting plate 52e at intervals for each set, and the angle γ is 45 degrees with respect to a driver at a short distance. Making it easy to see. In this way, the light emitting unit 60 is easily arranged by the driver from a distance or a distance.
In addition, the light-emitting portion mounting plate 52b and the light-emitting portion mounting plate 52e are easily visible to the driver even from a distance or at a place where the road is curved by providing a space between the front and rear. Further, the light emitting unit 60b and the light emitting unit 60d are arranged at the upper and lower end positions where the light emitting unit 60a is not provided so as to be visible when arranged on the entire apparatus as viewed from the driver side, and complement the light emitting unit 60a. It is arranged in such a position. The arrangement, position, and number of the light emitting units 60a, b, c, d can be changed as appropriate according to the road conditions. Needless to say, the arrangement and number of the light emitting covers 61 in the light emitting units 60a, b, c, d are the road conditions. It can be appropriately changed depending on
