An information processing method executed by a processor, the information processing method comprising: determining whether an emergency stop for causing a moving vehicle that is autonomously travelling to avoid a collision with an obstacle has occurred; characterized in that when it is determined that the emergency stop has occurred, simulating safety control based on situations that possibly lead to an occurrence of the emergency stop of the moving vehicle stored in a database, the safety control being an autonomous travel control for causing the moving vehicle to autonomously travel to avoid the collision with the obstacle without performing the emergency stop; obtaining a log of an autonomous driving system that executes the autonomous travel control of the moving vehicle, calculating a safety control time by comparing the safety control with the autonomous travel control indicated by the log, and identifying a process that is a cause of the emergency stop from processes for the autonomous travel control indicated by the log, based on the autonomous travel control indicated by the log and the safety control time, the safety control time being a start time of execution of the safety control in the autonomous travel control of the moving vehicle; obtaining, from the database related to the situations that possibly lead to an occurrence of the emergency stop, one or more situation candidates corresponding to the process identified, and presenting an interface to an operator for inputting a situation candidate from the one or more situation candidates that corresponds to a situation indicated by the log; and determining restartability of the autonomous travel control by the autonomous driving system according to the situation candidate input. determining whether an emergency stop for causing a moving vehicle that is autonomously travelling to avoid a collision with an obstacle has occurred; characterized in that when it is determined that the emergency stop has occurred, simulating safety control based on situations that possibly lead to an occurrence of the emergency stop of the moving vehicle stored in a database, the safety control being an autonomous travel control for causing the moving vehicle to autonomously travel to avoid the collision with the obstacle without performing the emergency stop; obtaining a log of an autonomous driving system that executes the autonomous travel control of the moving vehicle, calculating a safety control time by comparing the safety control with the autonomous travel control indicated by the log, and identifying a process that is a cause of the emergency stop from processes for the autonomous travel control indicated by the log, based on the autonomous travel control indicated by the log and the safety control time, the safety control time being a start time of execution of the safety control in the autonomous travel control of the moving vehicle; obtaining, from the database related to the situations that possibly lead to an occurrence of the emergency stop, one or more situation candidates corresponding to the process identified, and presenting an interface to an operator for inputting a situation candidate from the one or more situation candidates that corresponds to a situation indicated by the log; and determining restartability of the autonomous travel control by the autonomous driving system according to the situation candidate input.
