Abstract: A passage information providing device acquires information regarding movement of people on a road as people flow information. The passage information providing device estimates whether the road is passable by using the people flow information that has been acquired. The passage information providing device outputs passage availability information indicating the estimated state of whether the road is passable.

Abstract: Embodiments relate to a drawn composite fiber having a low thermal shrinkage, and a high single yarn strength, a non-woven fabric using the same, and a method of producing the same. The drawn composite fiber has a fineness of 0.6 dtex or less, a ratio between the cross-sectional areas of a sheath material and a core material (sheath material/core material) of 50/50 to 10/90, and a single yarn elastic modulus of 70 cN/dtex or more. The drawn composite is obtained by melt-spinning and a drawing treatment of an undrawn fiber having a sheath-core structure, in which the core material includes a resin containing a crystalline propylene-based polymer and having a melt flow rate of 10 to 30 g/10 min at a load of 21.18 N at 230° C., and the sheath material includes a resin containing an olefinic polymer where the melting point is lower than that of the core material.
