[Prior art]
In general, on urban expressways, there are many junctions that join or branch multiple routes. In these junctions, lane control based on road markings called channelization is used to prevent contact and rear-end collisions at junctions. Is planned. For example, in a junction where two lanes are joined together in a Y shape, an accident caused by merging the two lanes is prevented by restricting the two lanes to one lane.
[0003]
The road marking that controls the lane according to the prior art is to install a plurality of regulating plates formed of reflection and fluorescent materials in the direction of travel of the road, with arrows indicating the direction of road regulation to the driver.

It is a figure which shows the state installed.
[0009]
First, as shown in FIG. 3, the traffic control system according to the present embodiment is configured to drive one lane of a road surface 201 at a junction where a road surface 201 and a road surface 204 of each two lanes such as a capital expressway merge at a junction 205. The road marking machine 100, which is a feature of the present embodiment, is arranged in plural along the side wall 210 that is a road side member of the road surface 201.
[0010]
As shown in FIG. 1, the appearance of the road marking machine 100 is located at the top, a restriction plate 102 that indicates the traveling direction of the vehicle by an arrow symbol 105, and a mechanism that will be described later that is located on the back surface of the restriction plate 102. A frame plate 107 provided, an intermediate plate 103 located below the restriction plate 102 and provided with a mark indicating the traveling direction of the vehicle, and located on the back of the restriction plate 102 and the intermediate plate 103, and an arrow A restriction plate 104 that is driven up and down in the C direction and indicates the traveling direction of the vehicle by an arrow symbol 106, a support column 101 that rotatably supports the control plate 102 and the intermediate plate 103, and supports the support column 101, which will be described later. And a base mechanism 108 that reciprocally rotates the restricting plate 102, the intermediate plate 103, and the restricting plate 104 in the direction of arrow B by rotating the support column in the direction of arrow A by the mechanism. Further, the surfaces of the regulation plates 102 and 104 and the intermediate plate 103 are constituted by a cushioning material such as sponge or polystyrene foam that absorbs a collision force when the vehicle collides, or a cushioning body having a hollow structure.
[0011]
As shown in FIG. 2 which shows the internal structure of the road marking machine 100, the upper and lower and rotation driving mechanisms of the restriction plate include a rotation support portion 118 which rotatably supports a support column 117 in the pedestal mechanism 108, and a rotation support portion. A motor 110 that is a dynamic drive source, a gear 111 provided on a rotation shaft of the motor 110, a transmission gear 113 that engages with the gear 111 and changes a rotation speed, and one end of the rotation shaft 114 of the transmission gear 113 One end is wound around the rotating shaft 114 of the transmission gear 113 and the other end is a pulley 121 of the frame plate 107. And a rope 115 disposed so as to suspend the regulating plate 104 by a metal fitting 119 via
[0012]
In the road marking machine 100 configured in this way, in FIG. 2, the column is rotated to a position where the regulating plates 102 and 104 protrude at a predetermined angle (right angle in the illustrated example) with respect to the road surface. By rotating the motor 110 from this state, this rotational force is transmitted to the gear 111, the transmission gear 113, the bevel gears 116 and 117, thereby rotating the column 101 at an angle substantially parallel to the road surface. The rope 115 is wound around the shaft 114 in accordance with the rotation of the rotating shaft 114 of the carrier 113, so that the regulating plate 104 is driven to move upward via the pulleys 121 and 120.
[0013]
Therefore, the road marking machine 100 according to the present embodiment regulates the road surface by rotating the regulating plates 102 and 104 to an angle close to a right angle with respect to the road surface traveling direction as shown in FIG. 1 when regulating the road surface. At the same time, while the restriction plate 104 is moved upward and accommodated by the drive mechanism, the restriction plate 102 and the like can be rotated to an angle substantially parallel to the road surface traveling direction to move so as to guide the road surface traveling direction. it can.
[0014]
Further, when the road surface marking machine 100 does not restrict the road surface, the road surface marking machine 100 can guide the track along the road surface curve by rotating the restriction plates 102 and 104 to an angle close to parallel to the traveling direction of the road surface. it can. Further, the restriction plate 104 at this time is accommodated on the back surface of the restriction plate 102 by the above-described mechanism, and the restriction plate 104 can be positioned outside the route.
[0015]
Further, the road marking machine 100 according to the traffic regulation system according to the present embodiment is configured such that the angle of the regulation plate 102 is sequentially changed in the width direction from the near side of the vehicle entrance side toward the junction 205 with respect to the curved road surface 201 as shown in FIG. That is, the road route forms a junction that joins a plurality of routes at a junction, and the restriction plates 102 of the plurality of road marking machines 100 installed along the side wall 210 of the junction are connected to the junction. The angle is changed from an angle that is parallel to the road surface traveling direction to an angle close to a right angle as it goes from the intrusion side to the route 201 to the merging portion 205. Although the same size of the control plate is used, the size of the control plate is visually changed, Preventing abrupt steering operation in the rolling's safe can be to narrow down the vehicle and the lane. Further, the same effect can be obtained even if the restriction plates having different sizes are used. In other words, the same effect can be obtained by having a plurality of road marking devices arranged along the road surface have restriction plates that increase in size sequentially toward the junction.
[0016]
Furthermore, the traffic regulation system according to the present embodiment can arrange a surveillance camera or a sensor for detecting the amount of vehicle traffic at a junction as shown in FIG. 3, and can perform the most efficient lane regulation according to the traffic volume.
[0017]

By doing so, a lane regulation state can be changed easily. Furthermore, the road marking machine according to the present invention includes a plurality of restricting plates for instructing the traveling direction of the vehicle, and the restricting plates between a parallel position along the road route and a rotation position having a predetermined angle with respect to the road route. A rotating mechanism that rotates, and a mechanism that moves one of the plurality of restricting plates to a position that does not overlap the other restricting plate when the restricting mechanism rotates the restricting plate to the rotating position. By providing this, it is possible to easily change the lane regulation state at junctions such as the Metropolitan Expressway.
