Description

System for sharing road state on real time

The present invention relates to a real-time road situation sharing system, and more particularly, to a real-time road situation sharing system for real-time sharing of an accident occurring in a road.

Urban traffic demand is continuously increasing due to various factors such as increasing urban population, increasing urban complexity, and expanding internal economic activities. Urban traffic demand is usually measured as travel distance. According to Arthur D. Little, a consulting firm, global travel in urban areas is expected to increase 160 percent from 25.8 trillion kilometers in 2010 to 67.1 trillion kilometers in 2050. As a result, the time spent on the road due to traffic congestion is expected to increase from 58.4 hours per year to 106.3 hours per person during the same period.

Along with the prospect of urban traffic demand, the proportion of traffic accidents and traffic congestion are increasing along with the spread of vehicles. The increase in traffic accidents leads to personal injury and property damage. Traffic congestion leads to inconvenience of passage and air pollution.

Accordingly, in the event of a traffic accident on a road or a general accident such as a vehicle defect, it is possible to prevent the occurrence of a second traffic accident by sharing accident information, Measures are needed.

Hereinafter, the present invention will be described in detail with reference to the drawings. In describing the specific embodiments below, various specific details have been set forth in order to explain the invention in greater detail and to assist in understanding it. In some instances, it should be noted that portions of the invention that are not commonly known in the description of the invention and are not significantly related to the invention do not describe confusing reasons for explaining the present invention.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

Each of the configurations of the real-time road situation sharing system shown in FIG. 1 indicates that it can be divided into functions and logically, and does not necessarily mean that each configuration is divided into separate physical devices or written in separate codes The average expert in the field of the invention will readily be able to deduce.

In this specification, a DB may mean functional and structural combination of software and hardware for storing information corresponding to each DB. The DB may be implemented as at least one table, and may further include a separate DBMS (Database Management System) for searching, storing, and managing information stored in the DB. The DB can be implemented in various ways such as a Linked-list, a Tree, and a relational DB, and includes all data storage media and data structures capable of storing information corresponding to the DB.

The real-time road situation sharing system may be installed in a predetermined data processing apparatus to implement the technical idea of the present invention.

1 is a diagram briefly showing a data flow of a real-time road situation sharing system according to an embodiment of the present invention.

Referring to FIG. 1, when an accident occurs while a vehicle is running, a terminal (hereinafter referred to as 'user terminal') 100 of a user who has boarded the vehicle uses the road situation sharing application to obtain location information To the road-situation-sharing server 200. The road-

The road-situation sharing server 200 maps the accident information received from the user terminal 100 to the ID of the user or the ID of the vehicle, and stores it in a database (DB). Also, the road-situation sharing server 200 transmits the location information of the accident information among the accident information stored in the DB to a terminal (hereinafter referred to as 'another user terminal') 300 of another user who subscribes to the road situation sharing service .

The road situation sharing service is a service that enables a plurality of users to share an accident when an accident occurs in a moving vehicle and prevents the road situation from being further deteriorated by automatically registering the accident occurrence point as a congestion zone.

The other user terminals 300 automatically register the surrounding area including the location where the accident occurred as the congestion section and increase the intensity of the notification of the accident occurrence area as the congestion section is closer to the congestion section. Therefore, when the other user is driving the vehicle, it is possible to avoid entering the accident occurrence area in advance by referring to the location information of the accident or the automatically registered congestion section.

In addition, a peripheral terminal (hereinafter, referred to as 'peripheral terminal') 500 located near the accident occurrence point executes the road situation sharing application at the request of a nearby person who witnessed an accident, And transmits the created accident peripheral information to the road-situation-sharing server 200. The road-

The road situation sharing server 200 can transmit the current location information of the nearby persons among the received incident surrounding information to the other user terminals 300 subscribed to the road situation sharing service. At this time, the road-situation sharing server 200 may transmit the current location information of the nearby persons to the other user terminals 300 positioned within a predetermined radius (for example, 5 km) around the present location of the nearby person as accident information .

In order to provide such road situation sharing service, a road situation sharing application is installed in the user terminal 100 and other user terminals 300, and users and other users subscribe to the road situation sharing service using the road situation sharing application , And performs various environment setting for receiving the road situation sharing service.

In addition, although the data flow is shown in FIG. 1 in one direction, it is needless to say that data flow in both directions is also possible. That is, the user terminal 100 not only transmits incident information to the road condition sharing server 200 but also receives incident information provided from other user terminals 300 through the server 200 and processes the incident information.

2 is a diagram for explaining a series of operations for providing a road condition sharing service in a real time road situation sharing system according to an embodiment of the present invention.

Referring to FIG. 2, the APP 100 of the road situation sharing system is a road-state sharing application installed and executed in the user terminal 100 or the other user terminals 300, and the identification number uses '100' for the sake of convenience . The APP 100 is responsible for managing member systems subscribed to the road situation sharing service, managing a small bulletin board for members, maps and GPS analysis related to vehicle driving, push notifications according to information received from the server (200) and the Web (400) Perform basic configuration control management such as configuration.

The APP 100 transmits information that can be processed by the installed user terminal 100 or other user terminals 300 to the server 200. In particular, when the occurrence of an accident in the automobile is registered by the user, the APP 100 creates incident information and transmits it to the server 200. [ The accident information includes the current location information at which the accident occurred, the time of the accident, the type of accident, and the user ID.

The server 200 collects incident information transmitted from the APP 100, stores the collected incident information in the DB, and transmits the server data stored in the DB to the APP 100. The server data transmitted from the server 200 to the APP 100 may include location information of the accident occurrence among the accident information received from the other user terminals 300. In other words, the server 200 receives accident information from the APP 100, and when an accident occurs in the car of another user or on a road around the other user, It may be provided from the terminal located near the other user terminal 300 and provided to the APP 100.

In addition, the server 200 transmits the management data to the Web 400. The management data includes version information of the road situation sharing application included in the accident information transmitted from the APP 100, for example.

The Web 400 performs member management, bulletin board management, and push management to members' terminals by subscribing to the road situation sharing service. In addition, the Web 400 analyzes the management data received from the server 200 and manages the road situation sharing service. For example, if the version of the application installed in the user terminal 100 or the other user terminals 300 is lower than the latest version as a result of analyzing the management data, the Web 400 may manage the latest version of the application executable file And transmits the data to the user terminal 100 or other user terminals 300.

Also, the Web 400 can manage and transmit the ID, e-mail address, and accident information location data of the person who sent the data to the server 200 as management data. The Web 400 visualizes information registered in the server 200 and is for convenience of management.

3 and 4 are block diagrams showing a user terminal 100 and a road situation sharing server 200, respectively, in a real time road situation sharing system according to an embodiment of the present invention.

First, the contents set by the user for joining the road situation sharing service are described.

The user of the user terminal 100 and the other user terminals 300 executes the road situation sharing application, registers the member, and sets the selected incident radius. The selection radius is the distance from which the accident occurred if the user is located within a radius set around the accident location without being provided with the location information where the accident occurred unconditionally Information to be set. The user can set the desired radius, such as 1 km, 3 km, or 5 km, as the accident radius.

In addition, the required accident radius is set in the road situation sharing application. When the required accident radius is, for example, 500 m, the road situation sharing application informs that the accident occurs again when the user terminal 100 enters a radius of 500 m around the accident location.

The user terminal 100 may be a portable terminal such as a smart phone or a tablet PC, or a small terminal detachably attachable to a vehicle such as a navigation system. 3, the user terminal 100 includes a terminal communication unit 110, a terminal UI (User Interface) unit 120, a terminal storage unit 130, a GPS (Global Positioning System) sensor 140, A situation sharing application unit 150 and a terminal control unit 160. [

The terminal communication unit 110 transmits accident information created in the road situation sharing application unit 150 to the road situation sharing server 200 through the communication network 10 when an accident occurs while the user's vehicle is traveling.

The terminal UI unit 120 provides an interface path between the user and the user terminal 100, and may be a touch panel. In the embodiment of the present invention, the terminal UI unit 120 displays a screen and a pop-up window provided by the road-situation sharing application unit 150, and receives information and commands related to an incident through a displayed screen or a pop-up window from the user .

In the terminal storage unit 130, various programs necessary for the operation and execution of the user terminal 100 and a road situation sharing application are stored. Also, the terminal storage unit 130 stores the location information of the user terminal 100, which is sensed by the GPS sensor 140, together with the sensed time. When the user is on board the car and the road situation sharing application is running, the location information of the user terminal 100 is used as the location information of the car.

The GPS sensor 140 periodically senses the current position and direction information of the user terminal 100, for example, every one second.

The road situation sharing application unit 150 executes the stored road situation sharing application and periodically checks the location information (for example, the x coordinate and the y coordinate) sensed by the GPS sensor 140. The road-state-sharing application unit 150 generates a screen for confirming whether or not an incident has occurred if the received positional information is the same or the change rate of the positional information is small for a predetermined time range.

The road situation sharing application unit 150 determines that the rate of change of the location information is small if the difference between the previously received location information and the currently received location information is smaller than a predetermined reference distance. For example, if the preset time range is, for example, 5 seconds and the reference distance is 1 m, if the road situation sharing application unit 150 determines that the position information has not changed by 1 m or more for 5 seconds or more, Is generated in the form of a pop-up window.

If the user stands by for more than 5 seconds due to the signal waiting, the user may touch 'No' in the first query screen or take no action. The road-state-sharing application unit 150 determines that the vehicle is traveling again when the position information sensed from the GPS sensor 140 is continuously changed in a state where the user selects 'No' or no selection is inputted, 1 Cancels the display of the query screen.

However, if the user selects 'Yes' on the first query screen, the road situation sharing application unit 150 generates a second query screen that asks for the type of the accident. In the second inquiry screen, "traffic accident, road congestion, other" may be displayed as an accident type, and the user selects one of them.

The road situation sharing application unit 150 creates incident information including the type of the accident selected by the user, the current location information, the accident occurrence time, the user ID, and the road-situation sharing application version information. The user ID is an ID registered when the user joins the road situation sharing service.

The terminal control unit 160 controls and manages the overall operation including the above-described operations of the user terminal 100. [ The terminal control unit 160 controls the terminal communication unit 110 to transmit the generated incident information to the road condition sharing server 200 at the request of the road situation sharing application unit 150. [

4, the road condition sharing server 200 includes a server communication unit 210, a DB 220, and a server control unit 230.

The server communication unit 210 receives incident information from the terminal control unit 160.

In addition, the server communication unit 210 may periodically receive location information from other user terminals 300 subscribed to the road situation sharing service.

The DB 220 stores the received accident information in the form of a table. [Table 1] is a table for explaining accident information.

Field Information (description) Feature point Explanation ACNUM Number of accident registration Auto_increment Automatically increases the number of accident registration ID User ID ACCIDENT_TYPE Accident type (traffic accident, road congestion, etc.) LO_X The x coordinate value of the map map LO_Y The y coordinate value of the map map EDITDATE Version information of current application On update
CURRENT_TIMESTAMP Automatically update when the version of the application you are using is low. LOCATION The location of the x and y coordinates

In Table 1, for example, ACNUM is the number of registered accidents occurring in the user, that is, occurring in the user's vehicle, and automatically increases when accident information is received with the same ID. LO_X is the x coordinate of the sensed location information, and EDITDATE is the version information of the road situation sharing application installed in the user terminal 100.

Also, the DB 220 stores identification information such as a telephone number of other user terminals 300 subscribed to the road situation sharing service, an accident radius set by other users, and IDs of other users. Also, the DB 220 maps the location information of the other user terminals 300 provided from the other user terminals 300 to IDs of other users, and stores and updates the information.

In addition, the DB 220 stores server database information as shown in [Table 2].

Field Explanation VERSION Information that tells the server to check the version of the currently developed app STATE Information about current server status

Referring to Table 2, the DB 220 stores version information (VERSION) of the recently developed road situation sharing application and STATE information indicating the current server status. The VERSION information is information for automatically updating the road situation sharing application. In the system development, the user can check the version information of the road situation sharing application without accessing the market (that is, the server) . STATE information is information for notifying the user terminal 100 that downloading is being performed in order to prevent the driving of the road situation sharing application when the road situation sharing server 200 is downloaded.

The server control unit 230 controls the overall operation of the road situation sharing server 200. In the embodiment of the present invention, the server control unit 230 controls the DB 220 to store the accident information received from the user terminal 100.

The server control unit 230 transmits the location information LOCATION (x, y) where the accident occurred to all the other user terminals 300 subscribed to the road situation sharing service when the accident information is received from the user terminal 100 And controls the server communication unit 210 so that the server communication unit 210 can communicate with the server.

Alternatively, the server control unit 230 may check the current position of the other user terminals 300 in the DB 220, and may select only the other user terminals located within the pre-set selection accident radius around the point where the accident occurred The server communication unit 210 may control the server communication unit 210 to transmit the incident occurrence location information to only the selected other user terminals. For example, when another user who is a user of another user terminal 300 sets 3 km as the selected accident radius, the position of another user terminal 300 stored in the DB 220 is within 3 km of the accident occurrence position The server control unit 230 causes the other user terminal 300 to transmit the incident location information.

In addition, the server control unit 230 receives movement route information (for example, from the time when the accident occurred to a predetermined time) of the vehicle in which the accident occurred, from the road situation sharing application, and transmits the received route information to other user terminals (300). The travel route information of the vehicle can be known from the GPS of the user terminal 100.

If the application information EDITDATE stored in the DB 220 is lower than the latest version VERSION, the server control unit 230 automatically updates the road situation sharing application installed in the user terminal 100.

On the other hand, when the other user terminals 300 receive the accident occurrence location information and the travel route information of the accident vehicle from the road situation sharing server 200, the road situation sharing application installed in the other user terminals 300 The congestion section is automatically set. For example, the road situation sharing application automatically sets a radius of 500m or less, which is set as a required accident radius, to a congestion zone based on an accident occurrence location. The other user terminals 300 use the vehicle movement route information (for example, the x coordinate and the y coordinate log) to determine the movement path of the vehicle in which the accident occurred in the 360 degrees circle of the circle set as the congestion section And the highlighted road can be further highlighted with the congestion road.

When the vehicle of another user approaches the predetermined accident radius set in advance or approaches the travel path of the vehicle in which the accident occurred, the other user terminals 300, Informs the user of a voice or information message such as " I am close to the point of the accident ".

Other user terminals 300 also receive and collect current location information from the GPS sensor. Accordingly, when the other user's vehicle 300 is close to the automatically registered congestion period (for example, 1 km before entering the congestion interval), the ' It informs the information by voice and screen. Since the case of approaching the congestion section closer to the accident occurrence position than the case where the other user's vehicle enters the accident radius is closer to the accident occurrence position, the strength of the voice can be further increased when the other user terminals 300 are close to the congestion section .

The above-described operation is performed by the road situation sharing application installed in the other user terminals 300. [

FIG. 5 is a flowchart illustrating a road state sharing method of a real time road situation sharing system according to an embodiment of the present invention.

Referring to FIG. 5, the user terminal 100 periodically collects current location information of the user terminal 100 using the GPS sensor 140 (S505). The location information includes the (x, y) coordinate form.

The user terminal 100 compares positional information collected and calculates a change amount of positional information, i.e., a changed distance (S510).

If the changed distance calculated in step S510 is less than the preset reference distance (S515-Yes), the user terminal 100 determines that there is no movement of the user's vehicle, , A screen asking " Did an accident occur " is generated and displayed (S520).

If the user selects 'Yes' on the first query screen (S525-Yes), the user terminal 100 generates and displays a second query screen asking for the type of the incident (S530).

When the user selects one of the types of incidents displayed on the second inquiry screen (S535), the user terminal 100 determines whether or not an accident including the selected type of accident, current location information, accident occurrence time, user ID, Information is generated (S540).

The user terminal 100 transmits the created accident information to the road situation sharing server 200 (S545). The above-described steps S505 to S545 are performed by the road situation sharing application installed in the user terminal 100. [

Meanwhile, the road situation sharing server 200 stores the received accident information in the DB 220 (S550).

The road situation sharing server 200 confirms the current position of the other user terminals 300 in the DB 220 and determines a predetermined accident radius (for example, 1 km, 3 km, (Step S555).

The road-state-sharing server 200 transmits the incident location information to the other user terminals 300 (S560). The accident occurrence position information transmitted in step S560 is position information included in the accident information received in step S545.

The other user terminals 300 that have received the accident occurrence location information automatically set the congestion period using the necessary accident radius around the accident occurrence position (S565).

Then, the other user terminals 300 notify the other user's vehicle of the occurrence of an accident, such as a screen, a voice, or a siren, if the car of the other user enters within the pre-set selection accident radius or approaches the congestion period set in step S565. The steps S565 and S570 are performed by the road situation sharing application installed in the other user terminals 300. [

The embodiment of the present invention described above with reference to FIGS. 3 and 4 relates to an operation in which the user terminal 100 displays a query screen to a user and transmits the incident information to the road situation sharing server 200.

Alternatively, if an accident occurs, the user may execute the road situation sharing application installed in the user terminal 100 to create incident information directly. The user terminal 100 transmits the accident information created by the user to the road situation sharing server 200. [

In another embodiment, a nearby person in the vicinity of the vehicle in which the accident occurred may generate accident information. The nearby person may execute the road situation sharing application installed in the peripheral terminal 500 to directly generate the accident information. At this time, the peripheral terminal 500 adds the location information of the peripheral terminal 500 to the accident information, and transmits the created accident information to the road situation sharing server 200.

FIG. 6 is a diagram schematically showing a flowchart of a real-time road situation sharing system according to an embodiment of the present invention, centered on a database.

Referring to FIG. 6, the entire flow of the real-time road situation sharing system includes 'car accident information, accident recognition, accidental registration, automatic congestion section, accident registration, and user voice notification'.

The car accident information may include at least one of an accident type, (X, Y) coordinates, location information, and location information. The positioning information is the information that the user arbitrarily designates and registers the map when the GPS can not recognize the position at the accident point of the vehicle.

Accident recognition is recognized as an accident if the movement of the vehicle can not be recognized for a predetermined time (for example, 5 seconds).

Accident registration is the registration of the location of another user who boarded the vehicle in the vehicle where the accident occurred.

The automatic congestion section is defined as a congestion section with a radius of 500 m centering on the accident occurrence.

Accident registration is to register the accident information on the server and transmit it to other users.

The user voice alert notifies the user that an accident has occurred via a siren or voice, or that there is an accident point in a nearby location.

Meanwhile, the road state sharing method of the real time road situation sharing system according to the present invention may be provided in a recording medium which can be read through a computer by tangibly embodying a program of instructions for implementing the road state sharing method.
