and at least one processor configured to execute the set of instructions to: acquire a guidance route through which a guided person is to be guided from routes from a start-point position to an endpoint position; calculate, based on information relating to the routes, an influence level on the guided person in a case in which the guided person deviates from the acquired guidance route, with respect to each of branch places at which the guidance route branches into a route different from the guidance route; and output the calculated influence level. ## Claims ### Claim 1 A guidance assistance method, comprising: acquiring a guidance route through which a guided person is to be guided from routes from a start-point position to an end-point position; calculating, based on information relating to the routes, an influence level for each of routes at a branch place of the guidance route, the influence level being a value based on a tendency for deviation from the guidance route to occur at a branch place and an influence of the deviation; and outputting information based on the calculated influence level. ### Claim 2 (depends on 1) The guidance assistance method according to claim 1, wherein The outputting includes outputting the guidance route and the information relating to the routes. ### Claim 3 (depends on 1) The guidance assistance method according to claim 1, wherein the outputting includes outputting guidance information based on the influence level, the guidance route and the information relating to the routes, the guidance information being information for guiding the guided person to the guidance route. ### Claim 4 (depends on 1) The guidance assistance method according to claim 1, further comprising determining, based on the influence level for each of the branch places, a guidance position from the branch places, the guidance position being a position at which the guided person is to be guided, wherein the outputting includes outputting the guidance position. ### Claim 5 (depends on 1) The guidance assistance method according to claim 1, wherein the outputting includes outputting guidance assistance information based on the guidance route, the information relating to the routes, and the guidance position, the guidance assistance information being information for guiding the guided person to the guidance route at the guidance position. ### Claim 6 (depends on 1) The guidance assistance method according to claim 1, the method further comprising determining a target guiding person based on the guidance position and information relating to a guiding person, the target guiding person being a guiding person that is to conduct guidance at the guidance position, wherein the outputting includes outputting target guiding person information which is information relating to the target guiding person. ### Claim 7 (depends on 1) The guidance assistance method according to claim 1, wherein the outputting includes outputting guidance instruction information based on the guidance route, the information relating to the routes, the guidance position and the target guiding person information, the guidance instruction information being information for guiding the target guiding person to the guidance position. ### Claim 8 (depends on 1) The guidance assistance method according to claim 1, wherein the influence level is further based on an influence of taking a route other than the guidance route. ### Claim 9 (depends on 1) The guidance assistance method according to claim 1, wherein the tendency is based on a traffic volume of the guidance route and a traffic volume of a route other than the guidance route. ### Claim 10 (depends on 1) The guidance assistance method according to claim 1, wherein the tendency is based on a probability of the deviation at the branch place, the probability depending on complexity of a structure of the branch place. ### Claim 11 A guidance assistance system, comprising: at least one memory that stores instructions; and at least one processor configured to execute the instructions to: acquire a guidance route through which a guided person is to be guided from routes from a start-point position to an end-point position; calculate, based on information relating to the routes, an influence level for each of routes at a branch place of the guidance route, the influence level being a value based on a tendency for deviation from the guidance route to occur at a branch place and an influence of the deviation; and output information based on the calculated influence level. ### Claim 12 (depends on 11) The guidance assistance system according to claim 11, wherein the at least one processor is further configured to output the guidance route and the information relating to the routes. ### Claim 13 (depends on 11) The guidance assistance system according to claim 11, wherein the at least one processor is further configured to output guidance information based on the influence level, the guidance route and the information relating to the routes, the guidance information being information for guiding the guided person to the guidance route. ### Claim 14 (depends on 11) The guidance assistance system according to claim 11, further comprising the at least one processor is further configured to determining, based on the influence level for each of the branch places, a guidance position from the branch places, the guidance position being a position at which the guided person is to be guided, wherein the outputting includes outputting the guidance position. ### Claim 15 (depends on 11) The guidance assistance system according to claim 11, wherein the at least one processor is further configured to the outputting includes outputting guidance assistance information based on the guidance route, the information relating to the routes, and the guidance position, the guidance assistance information being information for guiding the guided person to the guidance route at the guidance position. ### Claim 16 (depends on 11) The guidance assistance system according to claim 11, wherein the at least one processor is further configured to: determine a target guiding person based on the guidance position and information relating to a guiding person that is to conduct guidance at the guidance position; and output target guiding person information which is information relating to the target guiding person. ### Claim 17 (depends on 11) The guidance assistance system according to claim 11, wherein the outputting includes outputting guidance instruction information based on the guidance route, the information relating to the routes, the guidance position and the target guiding person information, the guidance instruction information being information for guiding the target guiding person to the guidance position. ### Claim 18 (depends on 11) The guidance assistance system according to claims 11, wherein the tendency is based on a traffic volume of the guidance route and a traffic volume of a route other than the guidance route. ### Claim 19 (depends on 11) The guidance assistance system according to claim 11, wherein the tendency is based on a probability of the deviation at the branch place, the probability depending on complexity of a structure of the branch place ### Claim 20 A non-transitory computer readable storage medium storing a program causing a computer to execute: processing of acquiring a guidance route through which a guided person is to be guided from routes from a start-point position to an end-point position;
