Abstract: The moving body receives data from a remote monitoring apparatus and transmits data to the remote monitoring apparatus, via the wireless communication network. A candidate route acquisition unit acquires a candidate route of the moving body to a destination. A communication quality evaluation unit evaluates communication quality of the wireless communication network at each location included in the candidate route for each direction of communication by using communication quality information for each direction of communication. A candidate route evaluation unit evaluates communication stability of the candidate route by using communication quality evaluated for each direction of communication. A route determination unit determines a movement route of the moving body among the candidate routes by using an evaluation result of the communication stability.
