Route searching system, route guiding system, route searching program, and route guiding program

Abstract

A system that reduces the possibility of damaging items. A route searching system includes a type-of-item obtaining part that obtains a type of an item transported by a vehicle; a destination obtaining part that obtains a destination; and a route searching part that searches for a route that reaches the destination by selecting, based on the type of an item, a road with a low possibility of damaging the item on a priority basis over a road with a high possibility of damaging the item.

1 . A route searching system comprising:
 a type-of-item obtaining part that obtains a type of an item transported by a vehicle;   a destination obtaining part that obtains a destination; and   a route searching part that searches for a route that reaches the destination by selecting, based on the type of an item, a road with a low possibility of damaging the item on a priority basis over a road with a high possibility of damaging the item.   
     
     
         2 . The route searching system according to  claim 1 , wherein when the item is easily damaged, the route searching part reduces a possibility of selecting a road with a high possibility of damaging the item as a route over when the item is less likely to be damaged. 
     
     
         3 . The route searching system according to  claim 1 , wherein a road with a high possibility of damaging the item is at least one of a road with poor road surface conditions, a road including a steep slope, a road including a sharp bend, and a road with a relatively high probability of occurrence of an accident. 
     
     
         4 . The route searching system according to  claim 1 , wherein when a driving skill of a driver of the vehicle is low, the route searching part reduces a possibility of selecting a road with a high possibility of damaging the item as a route over when a driving skill is high. 
     
     
         5 . The route searching system according to  claim 1 , wherein
 a route obtained by selecting a road with a low possibility of damaging the item on a priority basis is a route that reaches the destination, the destination being a transport completion point of the item, and   when a route to the destination after the transport completion point is searched, a search that selects a road with a low possibility of damaging the item on a priority basis is not performed.   
     
     
         6 . The route searching system according to  claim 1 , wherein a road with a high possibility of damaging the item is a road on which the item has been damaged in a past. 
     
     
         7 . A route guiding system comprising:
 a route obtaining part that obtains a route for reaching a destination of a vehicle, the route being searched by selecting, based on a type of an item transported by the vehicle, a road with a low possibility of damaging the item on a priority basis over a road with a high possibility of damaging the item; and   a route guiding part that provides guidance on the route.   
     
     
         8 . The route guiding system according to  claim 7 , wherein when the route includes a road with a high possibility of damaging the item, the route guiding part provides guidance on the road before reaching the road. 
     
     
         9 . A non-transitory computer-readable storage medium storing a route searching program causing a computer to function as:
 a type-of-item obtaining part that obtains a type of an item transported by a vehicle;   a destination obtaining part that obtains a destination; and   a route searching part that searches for a route that reaches the destination by selecting, based on the type of an item, a road with a low possibility of damaging the item on a priority basis over a road with a high possibility of damaging the item.   
     
     
         10 . A non-transitory computer-readable storage medium storing a route guiding program causing a computer to function as:
 a route obtaining part that obtains a route for reaching a destination of a vehicle, the route being searched by selecting, based on a type of an item transported by the vehicle, a road with a low possibility of damaging the item on a priority basis over a road with a high possibility of damaging the item; and   a route guiding part that provides guidance on the route.   
     
     
         11 . A route searching system comprising:
 a type-of-item obtaining part that obtains a type of an item transported by a vehicle;   a destination obtaining part that obtains a destination; and   a route searching part that searches for a route that reaches the destination by selecting a road with a small change in acceleration on a priority basis over a road with a large change in acceleration, the acceleration acting on a vehicle due to at least one of road surface conditions and a road shape, and the route searching part changing a degree of selection of a road on a priority basis, based on the type of an item.   
     
     
         12 . The route searching system according to  claim 11 , wherein a road that allows acceleration to act on a vehicle due to the road surface conditions is a road with up-down acceleration greater than or equal to a threshold value. 
     
     
         13 . The route searching system according to  claim 11 , wherein a road that allows acceleration to act on a vehicle due to the road surface conditions is a road whose slope or curvature is greater than or equal to a threshold value. 
     
     
         14 . The route searching system according to  claim 11 , wherein a road that allows acceleration to act on a vehicle due to the road surface conditions is a road with a relatively high probability of occurrence of an accident. 
     
     
         15 . A non-transitory computer-readable storage medium storing a route guiding program causing a computer to function as:
 a type-of-item obtaining part that obtains a type of an item transported by a vehicle;   a destination obtaining part that obtains a destination; and   a route searching part that searches for a route that reaches the destination by selecting a road with a small change in acceleration on a priority basis over a road with a large change in acceleration, the acceleration acting on a vehicle due to at least one of road surface conditions and a road shape, and the route searching part changing a degree of selection of a road on a priority basis, based on the type of an item.
