An information provision device includes: a simulation execution unit that executes a simulation of a movement of moving bodies on multiple routes from a point of departure to a destination on a basis of setting data that accounts for different means of transportation; a simulation result analysis unit that obtains, as a simulation result, information related to a number and a density of the moving bodies on each of the routes from the point of departure to the destination on a basis of a result of the simulation execution unit executing the simulation; and an information provision unit that provides information based on the simulation result obtained by the simulation result analysis unit.

An ultra-high-pressure rotary water-jet gun capable of removing rust, scale, burrs, paint film and other unwanted deposits from the surface of metal, concrete and other materials. An air turbine serves to rotate an eccentric rotor within the gun housing. A high pressure water line passing through the rotor is connected to a nozzle head on which are mounted several nozzle tips. The nozzle head is rotated in a circular path by the eccentric rotor while directing the high pressure water jets against the work piece. A pneumatic circuit and a hydraulic circuit with certain controls are provided.
