dust generating device generating dust information for a road connection (L1, L21-L22, L51-L52), with a variety of position information elements (PO-PN) and time information elements (52),which are covered by one or more mobile information devices (21-21C) on the road link (L1, L21-L22, L51-L52) and the dust information device is configured, to generate dust information based on position information (PO-PN) and time information (52) for road connections (L1, L21-L22, L51-L52) with:a connecting speed calculator (42),which is configured to calculate a connecting speed of the road connection (L1, L21-L22, L51-L52) for each of the mobile information devices (21-21C), with the connecting speed calculation device (42) configured, the connecting speed of the road link (L1, L21-L22, L51-L52) from the position information (P0) and the time information (52),the nearest starting point (LS) of the road link (L1, L21-L22, L51-L52) and the position information (PN) and the time information (52) of an end point (LE) of the road link (L1, L21-L22, L51-L52) from the variety of elements of position information (PO-PN) and time information (52),to be calculated on the road link (L1, L21-L22, L51-L52);an information generating device (47) configured to generate the dust information of the road connection (L1, L21-L22, L51-L52) based on the road connection speed (L1, L21-L22, L51-L52); anda section speed calculator (42),which is configured to calculate a section speed (v1-vN) of a variety of sections (k1-kN) in the road connection (L1, L21-L22, L51-L52) for each of the mobile information devices (21-21C), with the section speed calculation device (42) configured, section speed (v1-vN) based on the variety of elements of position information (PO-PN) and time information (52),to be calculated on the road connections (L1, L21-L22, L51-L52), where:the information generating device (47) is configured to determine, for each of the mobile information devices (21-21C), whether the connection speed calculated for the road connection (L1, L21-L22, L51-L52) is used to generate the dust information; andthe information production device (47) is configured to determine whether the connecting speed is used to generate the dust information, based on at least a predetermined number or more of the section speeds (v1-vN), where:when all of the section speeds (v1-vN) in the road connection are calculated, the information generating device (47) is configured to determine this road connection (L1, L21-L22, L51-L52) as an entity for which the dust information is to be generated; andif not all of the section speeds (v1-vN) in the road connection (L1, L21-L22, L51-L52) are calculated, the information generating device (47) is configured to not determine this road connection (L1, L21-L22, L51-L52) as an entity for which the dust information is to be generated,where the information production facility (47) is configured so that, when the road connection (L1, L21-L22, L51-L52) designated as the entity for which the dust information is to be generated, the is connected to a non-designated road link (L1, L21-L22, L51-L52) and is adjacent to a railway line (TR1),the speed calculated for the specific road connection (L1, L21-L22, L51-L52) is not used to produce the dust information; andwhere a road link correlated with position information exists before a section where position information is not correlated with a road link exists, the information production facility (47) is configured to determine: whether the road connection runs parallel to the railway line (TR1); andwhere it is determined that the road connection does not run parallel to the railway line (TR1), and where a road connection correlated with position information is available in advance, even if two or more sections where the position information is not correlated with a road link are present, the information production facility (47) is configured to determine whether the road connection runs parallel to the railway line (TR1).
