  FIG. 5 is a view showing a plurality of vehicles 3 traveling on a road 100 in a specific area 200. As shown in FIG. Here, among the vehicles 3, a large vehicle and a vehicle for transportation are denoted as a vehicle 3az. The medium-sized vehicle and the vehicle for the manufacturing industry are described as a vehicle 3by. The small car and the mining vehicle are described as a vehicle 3cx. In addition, the medium-sized vehicle and the mining vehicle are described as a vehicle 3bx. The vehicle 3 may include a vehicle in idling or in a stop.

  In FIG. 5, the number of vehicles traveling on the road 100 in the specific area 200 is four. The breakdown of the four vehicles 3 is a large vehicle and a vehicle for transportation 3az, a medium vehicle and a vehicle for manufacturing 3by, a small vehicle and a vehicle 3cx for mining, and a medium vehicle and a vehicle 3bx for mining. Each of the vehicles 3 is equipped with the vehicle-mounted device 10, and periodically transmits operation data to the server 30.

  FIG. 6 is a graph showing the traffic volume of vehicles traveling on the road 100 in the specific area 200 according to month. The server 30 receives GPS position information periodically transmitted from the on-board unit 10 mounted on the vehicle 3. The server 30 acquires the vehicle code of the vehicle 3 traveling on the road 100 in the specific area 200 from among a lot of GPS position information. The server 30 refers to the vehicle master 81 included in the master information 61 based on the vehicle code, and acquires the vehicle type name and the type of industry of the corresponding vehicle code. The server 30 sums up the traffic volume of the vehicle traveling on the road included in the specific area for each vehicle type name and for each business type on a monthly basis. The server 30 creates an aggregation graph 150 of traffic by month, an aggregation graph 160 of traffic by vehicle type, and an aggregation graph 170 of traffic by industry for each month based on the aggregated result.

  In the traffic total graph 150 shown in FIG. 6A, the vehicles are not distinguished by the attribute. Therefore, the total number of vehicles is calculated as traffic volume. For example, the total number of vehicles in December is 9,000. In the aggregate graph 160 of the traffic volume for each vehicle type shown in FIG. 6B, the vehicles are classified into large vehicles, medium-sized vehicles, and small-sized vehicles. The numbers of large vehicles, medium-sized vehicles, and small vehicles are indicated by white, shaded, and black graphs in the figure, respectively. For example, of the total number of vehicles in December, 9,000, are 3,000 for large vehicles, 2,000 for medium-sized vehicles, and 4,000 for small vehicles. In the aggregate graph 170 of the traffic volume for each type of industry shown in FIG. 6C, the vehicles are classified into manufacturing industry, mining industry, and transportation industry. The numbers of vehicles in the manufacturing, mining, and transportation industries are indicated by white, shaded and black graphs in the figure. For example, of the total number of vehicles in December, 9,000, are 3,000 for manufacturing, 3,000 for mining and 3,000 for transportation.

  The server 30 can further display various contents graphically based on the result of the aggregation. FIG. 7 is a graph showing the gross vehicle weight and fuel consumption by month. The total vehicle weight graph 180 shown in FIG. 7A is a bar graph showing the total weight (total vehicle weight) of the vehicles traveling on the road 100 in the specific area 200 by month and by weight. The vertical axis of the graph represents the gross vehicle weight. The horizontal axis represents monthly units. The weight of the vehicle is a value obtained by adding the weight for each vehicle type and the loading weight. The weight for each vehicle type is the weight for each vehicle type registered in the vehicle type master 82. Further, the load weight is the weight of the load measured by the LI sensor 23 z attached to the vehicle 3.

  In the bar graph shown in FIG. 7A, the weight of the vehicle is divided into three classes of 0 to 5t (less than), 5t to 11t (less than), and 11t to (more than). The gross vehicle weight of each class is expressed on a monthly basis in the period from January to December. Three classes of 0 to 5t (less than), 5t to 11t (less than), and 11t to (more than) are indicated by white, shaded, and black graphs, respectively, in the drawing. For example, in July, the total vehicle weight of the 0-5t class is 1000t. The total weight of vehicles in the 5t to 11t class is 4000t. The total vehicle weight of the 11t to class vehicles is 1000t.

  Also, the server 30 can estimate the degree of deterioration of the road based on the total vehicle weight graph 180. The relationship between the degree of deterioration of the road and the total weight of vehicles passing the road during a predetermined period is experimentally obtained in advance. In general, it is believed that the heavier the gross weight of the vehicle, the greater the degree of road pain when one vehicle passes the road. Therefore, the gross weight of the vehicle of 11t to 1 class has a greater influence on the degree of deterioration of the road than the gross weight of vehicles of 0 to 5t class, and the vehicle gross weight is an important value when determining the degree of deterioration of the road.

  As described above, by measuring the weight of the vehicle actually resting on the road, it is possible to accurately estimate the degree of deterioration of the road. Therefore, the company managing the road can repair the road at an appropriate timing.

  The fuel consumption graph 190 shown in FIG. 7B is a bar graph showing the fuel consumption of the vehicle traveling on the road 100 in the specific area 200 on a monthly basis. The vertical axis of the graph represents the fuel consumption, for example, as a percentage (%) when the highest fuel consumption in the past is 100. The horizontal axis represents monthly units.

  In addition, the fuel consumption of the vehicle is, for example, an average of the fuel consumption of the vehicle 3 traveling on the road 100 in the specific area 200 in one month (within a predetermined period). It is a value. The fuel consumption of the vehicle 3 may be calculated for each vehicle, or may be calculated by adding the fuel consumption of all the vehicles 3 traveling on the road 100 in the specific area 200 within a predetermined period. Good.

  As described above, the fuel consumption amount is the fuel consumption amount calculated based on the fuel amount detected by the fuel amount sensor 29A, or the estimated fuel calculated by the server 30 based on the travel distance and the fuel consumption of the vehicle 3 Consumption is used. Further, the fuel consumption may be determined by measuring the amount of exhaust gas, in addition to the amount of fuel consumed. The server 30 calculates the fuel consumption of the plurality of vehicles 3 traveling on the road 100 in the specific area 200, and further calculates the average value of these. For example, in August, fuel consumption is 90%.

  An operation of the management system 5 having the above configuration is shown. FIG. 8 is a sequence diagram showing an operation procedure of the management system 5. The operation of the management system 5 shown in FIG. 8 is an example, and may be another operation example.

The traffic totaling graph to be created includes the traffic totaling graph 150 described above, the traffic totaling graph 160 for each vehicle type, and the traffic totaling graph 170 for each type of business.

  Furthermore, the server 30 creates the total vehicle weight graph 180 described above, and estimates the degree of deterioration of the road based on the total vehicle weight graph 180 (T6).

  The server 30 displays the created traffic total graph and the estimated degree of road deterioration on the display unit 33 (T7). At this time, the server 30 may superimpose the traffic total graph and the estimated degree of deterioration of the road on the map including the road 100 in the specific area 200. Furthermore, the server 30 may create display data for screen display in which a traffic total graph and the estimated degree of road deterioration are superimposed on a map including the road 100 in the specific area 200.

  The user PC 50 requests the server 30 for the traffic total graph and the degree of deterioration of the road via the network 70 (T8).

  When the server 30 receives the traffic total graph and the request for the road deterioration degree from the user PC 50, the server 30 returns the traffic total graph and the road deterioration degree to the user PC 50 via the network 70 (T9). At this time, map data including the road 100 in the specific area 200 may be transmitted together with the traffic total graph and the degree of deterioration of the road. Further, the server 30 may transmit display data for screen display in which a traffic total graph and the estimated road deterioration degree are superimposed on a map including the road 100 in the specific area 200.

  The user PC 50 displays on the display unit 53 the aggregation graph of the traffic volume and the deterioration degree of the road transmitted from the server 30 (T10). In the above steps T7 to T10, only one of the data of the traffic total graph and the degree of deterioration of the road may be processed.

  Thereafter, the user requests, for example, a fuel consumption graph 190 of a vehicle traveling on the road 100 in the specific area 200 (T11). The request for the fuel consumption graph 190 is an example, and may be another graph, for example, an aggregation graph of traffic volume by company name, an aggregation graph of traffic volume by fuel consumption, or the like.

  When server 30 receives a request for fuel consumption graph 190 from user PC 50, based on the fuel amount detected by fuel amount sensor 29A, or the fuel consumption and travel distance registered in vehicle type master 82, the aforementioned fuel consumption A graph 190 is created (T12). The server 30 displays the fuel consumption graph 190 on its own display unit 33 (T13). The server 30 sends the fuel consumption graph 190 back to the user PC 50 (T14). At this time, map data including the road 100 in the specific area 200 may be transmitted together with the fuel consumption graph 190. In addition, the server 30 may transmit display data for screen display in which the fuel consumption graph 190 is superimposed on a map including the road 100 in the specific area 200.

  The user PC 50 changes the screen of the display unit 53 to a screen displaying the fuel consumption graph 190 based on the display data including the fuel consumption graph 190 received from the server 30 (T15).

  Thereafter, the same operation is repeated. When the vehicle-mounted device 10 detects that the ignition switch 16 is off (ignition off) (T16), the vehicle-mounted device 10 stops transmission of the operation data.

  As described above, the management system 5 of the present embodiment adds up the traffic volume according to the attribute of the vehicle based on the information input from the on-board unit 10 of each vehicle 3 and causes the display unit 53 of the user PC 50 to display it. be able to. Therefore, unlike the conventional device in which only the total traffic volume is calculated based only on the position information of the vehicle, it is possible to grasp the traffic volume for each vehicle attribute such as for each vehicle type, for each industry, for each company. Of course, the total traffic volume can also be calculated if it is not restricted by the attribute.

  Further, the database 37 z associates and records the fuel consumption of the vehicle with the attribute of the vehicle 3. The CPU 31 averages, for each of the vehicle attributes, an average value of the fuel consumption of the vehicle 3 traveling on the road 100 in the specific area 200 (within a predetermined period) for one month (within a predetermined period) It is calculated and displayed on the display unit 53 of the user PC 50. Thereby, the CPU 31 can calculate the amount of fuel or exhaust gas consumed by the vehicle 3 included in the specific attribute on the road 100 in the specific area 200, and can display the amount on the display unit 53 of the user PC 50. Therefore, for example, it is possible to calculate the amount of exhaust gas caused by a vehicle owned by a specific company or a vehicle belonging to a specific industry.

  In addition, the database 37z associates and records the weight of the vehicle with the attribute of the vehicle 3. The CPU 31 estimates the degree of deterioration of the road (the predetermined area) based on the total weight of the vehicles traveling on the road 100 in the specific area 200, and causes the display unit 53 of the user PC 50 to display the degree of deterioration. Thus, the server 30 (management device) can calculate not only the traffic volume but also the deterioration degree of the road based on the information acquired from the vehicle-mounted device 10.

  Further, the on-board unit 10 further acquires information representing the load weight of the vehicle 3 and transmits the information to the server 30. The CPU 31 reflects the loaded weight in the calculation of the degree of deterioration. As a result, since the degree of deterioration of the road is estimated at a value close to the weight of the vehicle actually applied to the road, it can be expected that the estimation of the degree of deterioration will be more accurate.

  The technical scope of the present invention is not limited to the above-described embodiment. The embodiments described above can be accompanied by various modifications and improvements within the technical scope of the present invention.

  For example, a display device capable of displaying an aggregation graph or the like is an external display device such as an external display device directly connected to the server or a digital signage connected via a network, in addition to a display unit inside the server and a user PC. It may be.

  Also, the road in a specific area which is a predetermined area may be a part of the road, for example, only one lane, or both lanes. In addition, it may be part of a road divided in a specific area, or may extend over the entire length.
