Description

  The present invention relates to a road surface cutting method for forming a groove for embedding a loop sensor in an airfield where a vehicle road or an aircraft arrives and departs, and a traffic information control system using the road surface cutting method.

  A traffic information control system that detects vehicle information such as the number of passing vehicles and the number of passing vehicles, running speed, stop time, etc. necessary for road traffic management, and sends traffic information to traffic lights, traffic information management centers, or networked objects In this case, when a desired sensor is buried under the road surface of the vehicle and connected to the traffic signal with a cable, it is necessary to cut a recess for embedding the sensor on the road surface and a groove for the connection cable.

  There is also a method of detecting a vehicle from above as an aerial facility.

  Conventionally, a road surface cutter that cuts the road surface is a straight cutting method, and the road surface shape to be cut is a cutting method based on a straight line such as a rectangle or a polygon, or a large core boring machine is used for circular cutting. Or, it is customary to use a special cutter.

In addition, as patent information, a cutting device and a guide wheel are provided at the bottom of the self-propelled vehicle, and the cutting device is moved up and down in conjunction with the traveling of the self-propelled vehicle to form cutting grooves at predetermined intervals on the road surface. An invention is disclosed (for example, refer to Patent Document 1).
JP 2003-253619 A

  However, in the above-described conventional example (Patent Document 1), even though cutting grooves with a predetermined interval can be formed in parallel with the traveling direction of the self-propelled vehicle, it is almost impossible to cut a loop shape with a desired size. In general, it is difficult to cut a flat loop shape because cutting is performed continuously in a straight line. Large core boring machines and special cutters are expensive and have a large traffic regulation range. However, there is a problem that it is often inconvenient in terms of cutting time, traffic regulation range related to construction, and construction costs.

  In the case of an aerial facility, especially on a roadway with many lanes, in the situation where a vehicle detection sensor is provided every half mile as in the United States, for example, the facility cost increases and many problems occur.

  The present invention has been made paying attention to the above-mentioned points, and minimizes the traffic regulation range related to construction by using a circular cutting surface cutter having a predetermined blade thickness or a circular cutting / straight cutting road cutter. A road surface cutting method for forming a groove for burying a loop sensor in a vehicle road or an airfield that can reduce the construction time and reduce the equipment cost and the construction cost, and a traffic information control system using the road surface cutting method. The purpose is to provide.

  This invention can solve the said subject by providing the following structure.

  (2) Form a planar loop shape, a cross-sectional arc shape, and a groove with a predetermined width for embedding a loop sensor that senses a vehicle passing through a desired position on the road surface using a circular / straight-cut road surface cutter, A road surface cutting method for forming a groove portion for burying a loop sensor by connecting a straight groove portion for a cable to the groove portion.

  (3) A loop sensor embedding groove formed by inserting and embedding a loop sensor that engages with a loop sensor embedding groove provided by the road surface cutting method described in the preceding paragraph (1) and transmitting traffic information through a control panel is formed. Traffic information control system using road surface cutting method.

  (4) A loop sensor and a connecting cable, which are respectively engaged with a groove for embedding a loop sensor and a linear groove for a cable provided by the road surface cutting method described in (2) above, are inserted and embedded, and traffic information is transmitted via a control panel. A traffic information control system using a road surface cutting method for forming a groove for embedding a loop sensor.

  The present invention uses a circular cutter / straight cutter road surface cutter having a predetermined blade thickness, thereby minimizing the traffic regulation range related to the construction, shortening the construction time, and reducing the equipment cost and construction cost. It is possible to provide a road surface cutting method for forming a groove portion for embedding a loop sensor in a vehicle road and a traffic information control system using the road surface cutting method that can not only suppress the life of the entire system but also increase the life of the system. I can do it.
