First, the work route creation means 103 acquires the position information of the work site from the work site information of the work site on the same day from the work site information DB 105, for example, from the desired work date and time of the work site (step S201 in FIG. 9). Next, worker information of workers who are not on vacation is acquired from the worker information DB 105 (step S202 in FIG. 9). Next, the respective congestion status information of the work site and the road near the work site from the position information of the work site acquired from the road information DB 107 and the road at the worker position from the position information of the worker information acquired earlier are obtained. Obtain (step S203 in FIG. 9). The road to be used is preferentially selected from a plurality of candidates in the mesh including the positions X and Y of the work site, with a low degree of congestion. For example, the positions X and Y of the work site code “0001” in FIG. 2 are included in the mesh number “0001” in FIG. As can be seen from FIG. 6, the mesh number “0001” includes road codes “0001”, “0002”, and “0003”, and the road code “0001” with a low degree of congestion is selected from these. Next, based on the work site information, worker information, and road congestion status information obtained in this manner, the worker most suitable for the work at the work site, for example, any one of the plurality of workers, for example, any A work site is set, and the worker at the closest position of the work site is selected (step S204 in FIG. 9).

  Next, the estimated arrival time at which the selected worker arrives at the work site is calculated (step S205 in FIG. 9). At this time, if the selected worker has a work in progress, the estimated arrival time after the work is completed is calculated. Next, it is determined whether the estimated arrival time is within an allowable range (step S206 in FIG. 9). This allowable range can be set as appropriate according to the specifications of the work site work management system 101, such as when setting time for each work or when setting the same time as the system. If it is within the allowable range, a work route is created (step S208 in FIG. 9). If it is outside the allowable range, it is determined whether there is another worker who can work (step S207 in FIG. 9). If there is no worker, the process moves to step S208 while the worker is selected. If there is a worker, the process moves to step S204, and an optimum worker at a position closest to the work site is selected from each worker again, for example.

  Then, the work route creation unit 103 extracts necessary mesh information from the map information DB 119 based on the position coordinates corresponding to the work route, and from the map master information DB 106 based on the extracted mesh information. Extract necessary map information. Then, the work screen is generated by the map screen display means 102 so as to be displayed on the map screen. And it transmits to the portable terminal means 108 which the operator 109 carries via the network 113, ISP114, and the relay station 115 from the map transfer means 110, for example. In the portable terminal unit 108, the route information processing unit 1303 stores the route information in the route information file storage unit 1306. Then, work route information including map information is displayed on the map display unit 1301 via the route information processing unit 1303. Also, work information performed at the work site is input and stored in the work information file storage unit 1305 from the work information processing means 1302.

  According to the work site work management system of the first embodiment configured as described above, map information is obtained by selecting a worker based on work site information, worker information, road congestion status information, and map information. Can be created and provided to the worker, so the work route can be easily confirmed together with the map information.
