## Abstract

A travel route generation device (4) includes a travel route acquisition unit (4) configured to acquire position information (Pc) about a travel route (H) for a moving object (M) to perform autonomous travel or remotely controlled travel, a surrounding environment information acquisition unit (22) configured to acquire surrounding environment information, a dangerous location detection unit (23) configured to detect dangerous locations (Pd1 to Pd3) where there is a risk of an accident from the surrounding environment information, and an information processing unit (24) configured to add dangerous location information including first information indicating the dangerous locations (Pd1 to Pd3) to the position information (Pc) corresponding to the dangerous locations (Pd1 to Pd3).

## Claims

### Claim 1

A control device comprising:
a travel route generation device,
the travel route generation device including:
at least one memory storing instructions; and
at least one processor configured to execute the instructions;
wherein the at least one processor is configured to:
acquire position information about a moving object and acquire surrounding environment information which is information about a surrounding environment of the moving object, when the moving object does not perform autonomous travel or remotely controlled travel;
record the position information acquired as course information of a travel route along which the moving object is to perform autonomous travel or remotely controlled travel;
detect dangerous locations where there is a risk of an accident when the moving object travels along the travel route, from the surrounding environment information acquired;
add dangerous location information including first information indicating the dangerous locations, to course information corresponding to the dangerous locations detected of the course information recorded; and
store a course information table including the course information corresponding to the dangerous locations detected and the dangerous location information added to the course information corresponding to the dangerous locations detected, in a storage unit; and
wherein the at least one processor is further configured to:
add the dangerous location information further including second information indicating an operation of the moving object for reducing a risk at the dangerous location, to the course information corresponding to the dangerous location detected of the course information recorded; and
a travel control device,
the travel control device configured to cause the moving object to perform the autonomous travel or the remotely controlled travel on the basis of the course information table stored in the storage unit,
wherein the travel control device is further configured to control the travel of the moving object such that operation of the moving object indicated by the second information is performed when the moving object travels at a position of the course information to which the dangerous location information is added.

### Claim 2 (depends on 1)

The control device according to claim 1, wherein the dangerous locations include at least one of a first dangerous location having a road marking and a second dangerous location where the moving object and an obstacle are in proximity to each other.

### Claim 3 (depends on 1)

The control device according to claim 1,
wherein the second information includes information indicating that a travel speed of the moving object is decelerated to a prescribed speed or less.
