More specifically, the present invention relates to a system and method for calculating accessibility indexes of persons with disabilities, The present invention relates to a system and a calculation method of an accessibility index of a person with a disability who can calculate an accessibility index by calculating a score for each convenience means.

In the development of information and communication technology and the development of mobile technology, many people are providing and using information based on spatial information through mobile. However, the information required for the physically disabled or the elderly who have difficulty in moving is neglected. Especially, the difference of information and the qualitative difference of the information environment are becoming more and more widespread due to lack of geographical information facilities and accessibility information.

Mobile spatial information, which can be accessed anytime and anywhere on the network, is urgently required for the physically disabled and the elderly, but it is becoming an alienated class that is ignored even in the flood of information.

Techniques for guaranteeing the right of the disabled and narrowing the information gap with the non-disabled are disclosed. For the pedestrian or visually impaired, representative technologies are those that guide the route through voice, vibration, or other methods.

1, a conventional navigation system includes a GPS module 110, a short-range wireless communication module 120, a voice input unit 130, a braille input unit 140, A controller 150, a sensor unit 160, a database 170, an audio output unit 180, and a braille output unit 190.

The sensor unit 160 may include at least one sensor, such as a direction sensor, an acceleration sensor, etc., wherein the direction sensor can sense the direction of movement of the user, and the acceleration sensor can sense the movement speed of the user have. The detected moving direction and moving speed can be used to track the position of the user when it is determined that the accuracy of the GPS signal is degraded.

The prior art may activate a first navigation mode using a GPS module or a second navigation mode using a communication module depending on the user's location, e.g., indoor or outdoor, The GPS module 120 may receive the GPS signal and the communication module 120 may receive the wireless signal from the peripheral communication device via short-range wireless communication.

When receiving the GPS signal through the GPS module, the control unit 150 tracks the location of the user based on the received GPS signal, determines the movement path of the user based on the GPS signal, Upon receipt of a signal only, the location of the user can be tracked based on the received radio signal and the user's travel path can be determined based on the location of the user.

At this time, the database 170 includes building information for guiding the inside of the building such as information for guiding the inside of the building, for example, the location of an office inside the building, and map information for outdoor guidance such as a dangerous element, can do.

The voice input unit 130 receives destination information to be guided by the user through voice, and the braille input unit 140 can input such destination information as braille characters. Similarly, the sound output unit 180 provides the guidance information to the destination through voice, and the braille output unit 190 means braille display, which can also be provided through braille.

In the case of using the guidance system, it is possible to obtain information on the path for the disabled person to move from one place to another, but there is a limit to the information on whether the path is the most optimized path for the disabled person .

For example, in the case of a disabled person using a wheelchair, there is no way to know where the elevator for a disabled person is located when using the subway, and there is no way to inquire information such as a bus for a disabled person equipped with a lift for getting on and off a wheelchair. In addition, since it is impossible to know whether or not the means for persons with disabilities (moving ramps, guidance devices for persons with disabilities, etc.) are installed on the path for the disabled, there is a problem that the disabled actually meet various obstacles while moving.

In addition, there was a problem that, when a person with a disability intends to go to a particular building or facility, it is impossible to quantify the extent to which the building or facility can protect the rights of the person with disabilities.

FIG. 2 is a block diagram showing the configuration and connection state of the accessibility calculation system according to the embodiment of the present invention, and FIG. 3 is a flowchart showing a process of the accessibility calculation method of the present invention.

The accessibility index calculation system of the present invention (hereinafter referred to as an accessibility index calculation system) according to the present invention includes a map data server 300 for generating and providing map data and a map data server 300 for accessing a site such as a building or a road, A field manager terminal 400 used by a manager who checks the status, and a user terminal 500 such as a smart phone or a tablet PC carried by a disabled person or a dedicated navigation terminal.

The accessibility calculation system 200, the map data server 300, the field manager terminal 400 and the user terminal 500 are all connected through a network. The network in the present invention is a network capable of transmitting and receiving voice and data, And a mobile communication network.

The accessibility calculation system 200 calculates accessibility indexes for respective objects by grasping means for disabled persons installed in buildings, facilities, roads, public transportation, etc., and calculates accessibility indexes for respective objects by referring to the calculated accessibility indexes, And performs the function of generating information. The accessibility index and path information produced by the accessibility calculation system 200 are transmitted to the user terminal 500 and displayed as video or audio. A person with a gait or a visual impairment using the user terminal 500 can navigate to a desired destination by using the path information transmitted from the accessibility calculation system 200. [

The accessibility calculation system 200 is provided with a map information DB 210 and an application server 220.

The map information DB 210 receives and stores map data from a system that provides map data. The map data is received from the map data server 300. In the present invention, map data based on an Open Application Program Interface (API) is used.

In the case of using map data through Open API, it is possible to shorten the production period by not using a separate basic DB construction cost by using existing map data, and in addition to contents provided in existing map information, There is an advantage in that the quality of information to be served can be improved by providing accessibility information.

Since services such as Google Map, the next map and Naver map are provided on the basis of Open API, the present invention is also set to use such map data.

The application server 220 generates guidance map information for a disabled person's movement path by integrating the disabled facility installation information generated by itself into the map data collected from the map data server 300 and outputs the generated map information to the map information DB 210 ). Therefore, the map information DB 210 of the present invention stores special information for the disabled person in addition to the map data collected from the existing map service system.

The field manager terminal 400 is used for collecting information about an actual building or a road. When a field manager who is dispatched to the actual site and inputs information inputs the data, the access is made via the wired / wireless network to the accessibility calculation system 200 . The field data input by the field manager terminal 400 is combined with the map data by the application server 220, and the generated map information is stored in the map information DB 210.

Site managers are dispatched to buildings, roads, public transport facilities, and other hazardous areas to collect site information. The types and content of the information collected at the site will be described later.

The user terminal 500 includes a mobile terminal such as a smart phone or a tablet PC and has an environment for installing an application program for obtaining information on the accessibility index provided by the accessibility calculation system 200 of the present invention. The application program installed in the user terminal 500 displays information on the convenience means of the disabled person in the area where the user terminal 500 is presently located or the area selected by the user, and calculates and displays the travel route according to the contents inputted by the user.

The operation of the accessibility calculation system 200 will be described in order with reference to FIG.

First, the accessibility calculation system 200 or its manager sets an item to be an evaluation item of the accessibility index (S102). That is, it is determined whether the facility is to be scored when installed, . Scores are given for factors that help people with mobility, and scores for risk factors are scored. Depending on the type of facility, there may be differences in the amount of scoring.

4 is a table showing items for calculating the accessibility index.

For buildings such as schools, public buildings, large buildings, shopping malls, and shopping malls, it is necessary to judge whether it is easy for people with disabilities to enter the building, whether they can find the correct location inside the building, Element.

In the present invention, it is determined whether or not a moving ramp, a disabled parking lot, an elevator for the disabled, an emergency exit for the disabled, a restroom for the disabled, a braille block, a guide telephone, a videophone, and a guidance assistant are provided. The items exemplified here are representative means used for the convenience of persons with disabilities. In addition, various types of facilities can be used as a basis for awarding scores.

In the case of a moving ramp, a score can be given differently depending on the length and the inclination angle.

In the case of parking lots for disabled persons, a score can be given according to the ratio of the area of the parking lot for the disabled to the total area of the parking lot.

In the case of a guide assistant, a high score is given in the case of a dedicated staff member who works for the disabled person's walking, and in the case of a staff member who is in parallel with other guidance service, the granting of the score can be made a little lower.

In the case of roads such as India or a car, the score distribution may vary depending on whether a moving ramp, a braille block, an acoustic signaler, or a traffic light is installed.

In the case of crosswalks or crosswalks, there will be a relatively large difference in the score depending on whether there is a traffic light or not.

Public transportation facilities include buses, taxi stands, subway stations, railway stations, and airports, and are awarded points based on whether facilities for disabled people are available for easy and accurate public transportation.

For public transportation facilities, high scores will be given when a moving ramp, an elevator for disabled, an emergency exit for the disabled, a toilet for the disabled, braille block, guide assistant, voice alert service, and lift bus information are provided.

The voice notification service is a service that guides the arrival, departure and bus number of a train by voice for the visually impaired.

A lift bus is a bus equipped with an auxiliary device that allows wheelchair users to use when boarding a bus, and is given a high score if it is a stop that the lift bus stops, or if it indicates where the lift bus is currently located .

In case of dangerous area, the score is given according to the construction section information, the traffic accidents area warning, and the presence of stairs.

In the case of the construction section, a score is given by providing information on the contents and period of the construction and the bypass road, and the stairs are provided only with stairs without a moving ramp in the walking section. It does.

The field manager visits the facilities (buildings, roads, public transportation facilities, dangerous areas, etc.) to which scoring is to be applied, and obtains information on the presence or absence of the facilities for persons with disabilities (S104)

The field manager inputs data on the state of the facility to be analyzed using the field manager terminal 400 and transmits the data to the accessibility calculation system 200 (S 106)

The application server 220 arranges the data transmitted from the field manager terminal 400 and calculates the score for each item (S108)

The score for each item is calculated by integrating the convenience facilities, the type and grade of installed facilities, and other management status.

FIG. 5 is a table showing an example of scores for each item in FIG.

For example, in the case of a moving ramp, 10 points may be given when the inclination angle is less than 0 degrees and less than 6 degrees, 7 points when the inclination angle is less than 12 degrees, and 3 points when the inclination angle is more than 12 degrees. In other words, if the inclination angle of the moving ramp is small and the wheelchair can easily ascend, it is given a high score because the accessibility of the disabled person is good. Otherwise, the appropriate score is given according to the angle.

In the case of parking lots for disabled persons, the number of parking spaces for persons with disabilities is 10, 10, 5, or 1 if there is more than 10% of the total number of parking spaces.

In the case of handicapped toilets, 10 points can be given for individual toilets that can be used exclusively by persons with disabilities, 5 points for those in shared toilets used with non-disabled persons, and 2 points for non-disabled toilets.

In the case of a guidance helper, 10 points can be given if there is a dedicated staff member, and 5 points if the security guards are in charge of general guidance service.

Other services such as elevators for disabled persons, emergency exit for disabled persons, braille blocks, information telephones, videophones, sound signals, traffic lights, voice notification services, and lift bus information can be given depending on the presence or absence.

However, the score calculation criteria described in Fig. 5 are only one example, and the scores can be calculated in different ways depending on the type, nature, frequency of use, and the like of the convenience means.

The application server 220 calculates the accessibility index of the target facility by summing the scores for each item (S110)

As shown in FIG. 4, assuming that the building is judged to be 9 items, the score is 90 when all 9 items are full marks. Therefore, the numerical value obtained by dividing the score of the actual 9 items by 90 can be set as the accessibility index have.

For example, if a shopping mall has a score of 70 when it combines 9 items, the accessibility index of the shopping mall is 70/90 (= 0.78). This can be expressed as [7.8 / 10] based on a score of 10, or as [78/100] based on a score of 100.

In the case of roads, if the score of four items is 30 points, 30/40 (= 0.75), the accessibility index can be expressed as [7.5 / 10] or [75/100].

The number of items to calculate accessibility score, the score of each item, the total score, etc.

Finally, the application server 220 stores the calculated accessibility index in the map information DB 210 (S112). When storing the accessibility index in the map information DB 210, the application server 220 combines the accessibility index into the map data collected from the map data server 300, You can create map information with indicators.
