Vehicle travel control method and vehicle travel control device

A travel control method for a vehicle performed by a controller including a processor, wherein the controller is configured to:

• specify a pedestrian crosswalk through which a subject vehicle is expected to pass as a first pedestrian crosswalk;
• specify another pedestrian crosswalk located within a predetermined distance from the first pedestrian crosswalk as a second pedestrian crosswalk;
• perform an extension process of extending an area of at least one of the first pedestrian crosswalk and the second pedestrian crosswalk;
• determine whether or not at least a part of the area of the first pedestrian crosswalk subjected to the extension process and at least a part of the area of the second pedestrian crosswalk subjected to the extension process overlap each other;
• when a determination is made that at least a part of the area of the first pedestrian crosswalk subjected to the extension process and at least a part of the area of the second pedestrian crosswalk subjected to the extension process overlap each other, set an area including the first pedestrian crosswalk and the second pedestrian crosswalk as a detection area of a detector detecting an object around the subject vehicle;
• detect a moving object in the detection area using the detector;
• and
• control travel of the subject vehicle on a basis of a detection result of the detector.
