In a case where a CPU provided in an information distribution center has received, from a navigation apparatus, vehicle information together with a request command for requesting traffic information such as current traffic information, the CPU sets a road category that serves as a distribution target of the traffic information, based on one of a distance and a required travel time from a vehicle position to a destination. The CPU then extracts the traffic information that corresponds to the set road category and distributes it to the navigation apparatus.

The invention discloses a composite face brick paving tool and a paving method thereof and belongs to the technical field of architectural ornament. The composite face brick paving tool comprises a control panel, a heating panel, a fixing device and a support device, the control panel is connected with the heating panel, the fixing device is arranged right on the support device, and the heating panel is positioned on the fixing device and movably connected with the support device. The composite face brick paving tool and the paving method thereof have the advantages that the paving tool is simple in structure and integrates a paving function with a heating function, the problem that a conventional paving tool cannot meet a paving heating requirement of a novel composite face brick in the prior art can be solved, the face brick can be surely paved in one step without displacement adjustment, the problem of uneven level during construction of workers is avoided, high construction quality is guaranteed, construction efficiency is improved, requirement of the decoration industry on quick paving is met, composition of the face brick is facilitated by means of integrating heating with paving, and quick industrial production is benefited.

The invention discloses a complex plain river network generalization method achieving an approximately-uniform water storage relation. The method includes the steps that river channel geographic information data are obtained and processed; a simulated river network polygon is constructed; total water storage amount parameters of a generalized river network inside the simulated river network polygon are determined; the overlapping width of each simulated river sections of the river network polygon is determined; the width overlapping position of each river section of the river network polygon is determined. The water storage capacity of the generalized river network can be made to be approximately uniform with that of a prototype river network, simulation precision can be effectively improved, and the flood risk is easily analyzed; for the water administrative department in charge, defined data requirements are provided, and therefore data compiling is easily performed in management work of the plain river network; for scientific researchers in the water conservancy industry, the method is adopted for constructing a generalized river network hydrodynamic model, and in this way, it can be avoided that due to excessive dependency on experience, different researchers construct the model at different levels.
