Establish a measurement area upstream of the road where the vehicle specifications such as weight, dimensions, etc. exceed the allowable values permitted by road regulations, and measure the vehicle specifications of the vehicle in the measurement area. It is determined whether or not the allowable value is exceeded, and if it is exceeded, a warning that the vehicle is in violation is displayed on the vehicle, and an approach to a road without traffic restriction is promoted (for example, patent document) 1).
JP 2002-230104 A

  However, since the device that measures the vehicle specifications is a large-scale device with multiple portal columns installed, it is necessary to install it on a flat straight road in order to measure weight with high accuracy, There was a problem that the installation point was limited. For this reason, the measurement device and the device that displays a warning immediately after the measurement device are not necessarily installed immediately before the point at which the warning is originally intended, that is, immediately before a branch point between a road with traffic restriction and a road without traffic restriction.

  If these devices are installed at a point far upstream from the above branch point, the driver of the violating vehicle actually takes time to reach the above branch point even if a warning is received at that point. If you forget that your vehicle should enter a road with no traffic restrictions when approaching the branch point, or if there are multiple destinations, you may not know which road has no traffic restrictions that your vehicle should enter In addition, there was a risk of accidentally entering a road with restricted traffic.

  Accordingly, an object of the present invention is to provide a vehicle traffic management system that can prevent a driver of a violating vehicle from entering a road with restricted traffic regardless of the installation location of a device that measures vehicle specifications. And

  The vehicle traffic management system of the present invention provides a first point upstream from a branch point between a restricted road that restricts the passage of a prescribed vehicle whose vehicle specifications exceed a prescribed range and an unrestricted road that does not restrict the passage of the prescribed vehicle. A vehicle traffic management system that determines whether or not a passing vehicle corresponds to the predetermined vehicle, and warns the vehicle when it is determined that the vehicle passes, the vehicle passing through the first point at the first point Vehicle specification and first acquisition means for acquiring first specification information for specifying the vehicle, and the second point downstream of the first point and upstream of the branch point A second acquisition unit that acquires second specifying information for specifying a vehicle passing through the point; and a first output unit that outputs first warning information to the vehicle, the first acquisition unit acquiring Based on vehicle specifications and the predetermined range First determination means for determining whether or not a vehicle corresponds to the predetermined vehicle, the first specific information about the vehicle determined by the first determination means to correspond to the predetermined vehicle, and the second specific information; Second determining means for determining whether or not the two match, and the first output means is configured to output the first warning information when it is determined that the second determining means matches. (Claim 1)

  Here, the vehicle specifications refer to vehicle weight, vehicle width, vehicle height, vehicle length, axle load, number of axles, axle distance, and the like. In addition, the point has a spatial spread, for example, the first point has a width of 15 m in the direction of travel of the road, the width of the road in the width direction of the road, and the second point is the progress of the road It has a width of 100 m in the direction and the width of the road in the width direction of the road.

  For example, at the first point upstream of the junction between a restricted road with restricted traffic and a non-restricted road without restricted traffic, the vehicle specifications of the passing vehicle are measured, and the vehicle is a violation vehicle ) Or not. At this time, the vehicle number of the vehicle is also read. If it is determined that the vehicle is in violation, the vehicle number of the passing vehicle is read at the second point downstream of the first point and immediately upstream of the branch point. Warn the vehicle that it should enter an unrestricted road. The warning is performed by, for example, displaying on a road information board. As a result, even if the first point where the device for measuring vehicle specifications is installed is considerably upstream from the branch point, the driver of the violating vehicle is warned at the second point immediately upstream from the branch point. Can be prevented from accidentally entering the restricted road.

  In addition, the vehicle traffic management system acquires a third specifying unit for acquiring third specifying information for specifying a vehicle passing through the third point at a third point on the restricted road downstream from the branch point. And second output means for outputting second warning information to the vehicle, wherein the first specifying information about the vehicle determined by the first determining means to correspond to the predetermined vehicle, and the third specifying A third determination unit configured to determine whether or not the information matches, and the second output unit is configured to output the second warning information when it is determined that the third determination unit matches. (Claim 2).

  Here, the third point has a spatial extent, for example, 100 m in the traveling direction of the road and an extent corresponding to the width of the road in the width direction of the road.

  For example, at the third point on the restricted road downstream from the branch point, the vehicle number of the passing vehicle is read, and if this matches the vehicle number of the violating vehicle, it is indicated that the vehicle should run at a low speed. Warning. As a result, even if the driver of the violating vehicle misses the warning displayed on the road information board at the second point and accidentally enters the restricted road, the driver of the violated vehicle should drive at a low speed on the restricted road, etc. Therefore, it is possible to minimize damage to the road caused by the violating vehicle traveling on the restricted road.

  Moreover, it is preferable that the specific information is vehicle number information. This is because the vehicle number information can be acquired from all passing vehicles.

  As described above, according to the vehicle traffic management system of the present invention, when the device for measuring vehicle specifications is installed at a point considerably upstream of a branch point between a road with traffic restrictions and a road without traffic restrictions. Even if there is a warning, a warning is displayed to the driver of the violating vehicle at a point downstream from the installation point and upstream from the branch point, thus preventing the driver from accidentally entering a road with restricted traffic. it can.

The method of determination is the same as in the case of the vehicle number data received from the vehicle number reader 4a. If it is determined that the vehicle number of the vehicle exceeds the allowable value, warning information W3 for instructing the vehicle exceeding the allowable value to run at low speed is created and transmitted to the road information board 3c to display the warning information W3. Let The warning information W3 is, for example, “12-34 Reduce the speed” when the vehicle with the vehicle number “12-34” is a vehicle that exceeds the allowable value.

  As a result, even if the driver of the vehicle that exceeds the allowable value misses the warning information W2 on the road information board 3b and the vehicle enters the restricted road RA, a warning is given so that the vehicle runs at a low speed on the restricted road RA. Road damage caused by the excess vehicle traveling on the restricted road RA can be minimized.

  Further, the processing unit 205 receives vehicle number data from the vehicle number reading device 4c via the communication unit 204. The processing unit 205 determines whether or not the received vehicle number data is a vehicle number of a vehicle that exceeds an allowable value. The method of determination is the same as in the case of the vehicle number data received from the vehicle number reader 4a. When it is determined that the vehicle number of the vehicle having exceeded the allowable value is exceeded, it is determined that the vehicle having exceeded the allowable value has left the unrestricted road RB, and the vehicle number is stored from the allowable value excessive vehicle table stored in the storage unit 203. Delete the data.
