The travel road determination device includes a vehicle position acquisition unit and a travel road determination unit. The vehicle position acquisition unit acquires position information of a vehicle. In the first determination process, the travel road determination unit determines, on the basis of second position information of the vehicle and first map data, whether or not the vehicle determined to travel on the first type of road begins to travel on the second type of road on the basis of the first position information of the vehicle. The first type of road is a road whose road shape is represented by first map data including road shape data for lane units. The second-type road is a road in which the road shape is represented by second map data including road shape data for road units. In the second determination process, the travel road determination unit determines, on the basis of the fourth position information of the vehicle and the second map data, whether or not the vehicle determined to travel on the second type of road on the basis of the third position information of the vehicle begins to travel on the first type of road.
行驶道路判定装置包含车辆位置获取部以及行驶道路判定部。车辆位置获取部获取车辆的位置信息。在第一判定处理中,行驶道路判定部基于车辆的第二位置信息和第一地图数据来判定基于车辆的第一位置信息而判定为在第一类别道路上行驶的车辆是否开始在第二类别道路上行驶。第一类别道路是通过包含车道单位的道路形状数据的第一地图数据来表现道路形状的道路。第二类别道路是通过包含道路单位的道路形状数据的第二地图数据来表现道路形状的道路。在第二判定处理中,行驶道路判定部基于车辆的第四位置信息和第二地图数据来判定基于车辆的第三位置信息判定为在第二类别道路上行驶的车辆是否开始在第一类别道路上行驶。
