In the data recency determination step (S330), if overlapping data exists in the data redundancy determination step (S320), the recency of the extracted walking path information data 10 may be determined. If there is a difference in the collection time, the data of the previous time can be deleted and the most recent data can be used. However, when overlapping data is collected at the same time, that is, when there is no difference in recency between the overlapping data, the data may be used according to the priority of the walking path information provider set in advance.

According to an embodiment of the present invention, GIS data is used as basic data in road information data 11-1, building information data 11-2, and building information data 11-3 among walking path information data 10. However, since the type of data held by the GIS data collection unit is different for each region and the center coordinates are different, there may be a difference and the update cycle is slow, so the lowest priority can be given. In the case of a video record collection unit such as cctv, since a specific section is captured in real time, it has high reliability and can be given the highest priority. In addition, since walking route information data can be obtained from social mapping data in the case of a point where walking route information data is not collected through cctv, such as an alley on a walking road that is not captured by cctv, that is, in the case of a blind spot on a walking route, the walking route information is obtained from the video record collection unit. In the case of blind spots on pedestrian paths where data collection is impossible, the highest priority can be given to the social mapping data collection unit, and in the case of the IoT sensor data collection unit, the highest priority can be given to environmental information data. , may be changed as needed, but is not limited thereto.

That is, in the data recency determination step (S330), road information data, building information data, facility information data, non-fixed obstacle data, and safety information data, excluding environmental information data, are simultaneously duplicated from the walking route information provider. and collected, data is extracted in the order of video record collection unit, social mapping data collection unit, and GIS data collection unit. It is set as a high priority, and in the case of environmental information data, the IoT sensor data collection unit can be set as the highest priority when extracting data.

For example, the walking path information collection unit receives raw data A including non-fixed obstacle data a at a specific point on the walking path from the GIS data collection unit, and at the same time, the non-fixed obstacle data a at the specific point from the image record collection unit Raw data B that is not included can be collected. At this time, even if the raw data A received from the GIS data collection unit is received at the same time as the raw data B, since the time when the actual data was created may be earlier than B, accuracy and recency may be lower than B. Accordingly, the accuracy and reliability of the data can be greatly improved by extracting the data that does not include the non-fixed obstacle data a collected from the video record collection unit, which is the highest priority, as the non-fixed obstacle data.

In addition, even if environmental information data related to icing at a specific point on the walking path is not acquired from the video record collection unit, environmental information data related to icing at the specific point is obtained from the environmental information data acquired from the IoT sensor data collection unit at the same time. is received, it is assumed that icing has occurred, and environmental information data can be extracted.

In the walking path information data classification step (S400), the extracted and processed walking path information data 10 may be classified according to characteristics in the walking path information layer 20.

For example, road information data (11-1) including facility information such as road location, building size and shape information, street lights, and telephone poles collected from GIS data, building information data (11-2), and building information data ( 11-3) may be classified and stored in a road information layer 21-1, a building information layer 21-2, and a facility information layer 21-3, respectively.

In addition, in the case of non-fixed obstacle data (12-1) such as illegal garbage discharge and illegal parking on the walking path collected through cctv, it can be classified as a non-fixed obstacle layer (22-1), and the icing section on the footpath from cctv Environment information data 12-2, such as a water pool or a water pool, may be classified as an environment information layer 22-2.

In the step of receiving user information and departure/destination information (S500), it is related to the user's walking ability, including physical information such as gender, age, disability, and type of disability, and disability assistive means including wheelchairs, canes, and guide dogs, and accompanying persons. User information including the presence or absence of may be collected from the user terminal 100 . Based on the user information, an optimal walking path suitable for a pedestrian type may be provided to the user terminal 100 .

In addition, location information of departure and arrival locations may be received from the user terminal 100 . It is possible to determine whether or not the pedestrian can move along the walking path on the walking path existing from the received starting point to the destination, and provide the user terminal 100 with an optimal walking path according to the determination.

In step S600 of determining whether a user can move to a walking path (S600), when receiving user information and departure and destination information from the user terminal 100, user information and walking path information data 10 among walking paths that exist from the departure point to the destination point are used to determine the user's location. It is possible to determine whether or not it is possible to move on a walking path.

For example, if the user is an ordinary person without a disability, it may be determined that all routes are movable except for special cases such as an area where an accident occurred or an area visited by a corona infected person.

In addition, when the user is a visually impaired user, it may be determined that a section in which a braille block exists may be walked, and a section in which a braille block is not present or damaged may be determined to be incapable of walking for a visually handicapped user.

In addition, if the user is a wheelchair user, it may be determined that walking is impossible at a point where the wheelchair cannot pass because the width of the walking path or building entrance is narrower than the wheelchair, or a sloped section where the wheelchair cannot climb because the slope is high.

Here, if the user is a wheelchair user, whether or not the user can move to the walking path may be determined according to whether the wheelchair is automatic (electric) or manual. Even in the same inclined section, manual wheelchairs cannot climb, but automatic (electric) wheelchairs can climb, so there are sections, so it is possible to determine whether or not it is possible to move to a walking path according to the type of wheelchair by determining the level of difficulty of the slope.

In addition, in the case of the disabled and the elderly, if there are multiple walkable paths between the starting point and the ending point, the path with pedestrian road facilities such as a pedestrian-only road, a crosswalk, a non-slope road, and a pedestrian lift can be given priority to the user. .

In addition, in the case of a disabled person, whether or not they can move on a walking path may vary depending on the presence or absence of a companion. If there is a companion, it is possible to move the path that the visually impaired person or a wheelchair alone could not move with the help of a companion.

At this time, in step S600 of determining whether movement of the walking path is possible, it is possible to determine whether or not the user receiving the walking path can move to the corresponding section according to the user information provided with the user movement path data 13 .

For example, if there is data 17 of the wheelchair user's movement path for point A, if data interfering with walking has not occurred at point A until the time of determining whether or not the walking path is possible, the information of the user who provided the movement route data All pedestrians similar to point A can be determined to be walkable.

That is, as long as there is path data that the user has traveled for a specific section, it is possible to determine whether or not a user who provided the movement path data can move to a walking path similar to the user who provided the movement path data even if other walking path information data 10 does not exist, thereby enabling walking. It is possible to secure high reliability and accuracy of determining whether or not.

Accordingly, in the step of determining whether movement on the walking path is possible (S600), it is possible to determine whether movement on the walking path is possible according to the type of pedestrian by selecting the user movement path data as the highest priority.

User movement route data ( 13), the pedestrian corresponding to the user may determine that the corresponding section is walkable.

For example, on July 13, 2021, section A unavailability data was collected as road information data (11-1), and then use section A until 10:00 am on July 14, 2021, at which point it is determined whether or not the pedestrian path can be moved If there is unavailable data, if the wheelchair user's movement route data (17) exists for section A at 8:00 am on July 14, 2021, even if the available data for section A is not collected, the user's movement route data (13 ) as a top priority, it is possible to determine that section A is walkable by ordinary people and wheelchair users.

That is, even if there is obstacle data for a section, if the user movement path data 13 is collected in the section after the time the obstacle data is collected, the section can be determined to be walkable according to the type of pedestrian, so the walking path is moved. There is an advantage in that the accuracy and reliability of the determination of availability are greatly improved.

In the optimal walking path generation step (S700), at least one optimal walking path suitable for the type of pedestrian may be created from the starting point to the destination according to the determination result of the step of determining whether the walking path can be moved (S600).

In the step of providing an optimal walking path ( S800 ), the at least one optimal walking path may be provided to the user terminal 100 .

That is, by providing at least one optimal walking path suitable for the user's walking ability based on user information and walking route information data, so that wheelchair users and visually impaired pedestrians can easily and easily reach from the starting point to the destination. There is an advantage to
