Description

Method and device for providing traffic information according to accident information on traveling course and Record Medium saved the method}

The present invention relates to a method, an apparatus for providing a driving route corresponding to real-time traffic information between a starting point and a destination, and a recording medium recording the method, and more particularly, notice information such as a traffic accident on a provided driving route may be generated. The present invention relates to a method, an apparatus for providing traffic information according to notice information on a driving route for providing traffic information to a terminal in real time, and a recording medium recording the method.

There are two ways to provide a driving route reflecting real-time traffic information according to the prior art.

First, the terminal calculates a route in a specific device that provides traffic information and downloads the calculated driving route through a communication network. It cannot reflect the changed traffic situation on the driving route after the customer requests the driving route to the destination and downloads it. In addition, in order to reflect the changed traffic information, it is difficult to obtain the consent of the customer due to the connection time and additional charges caused by the automatic re-search without the request of the customer, and the unnecessary load on the device increases, increasing the system load. In addition, sending all the notice information generated to all customers may result in providing unnecessary information to the customer (for example, informing the customer operating in Busan about the notice information generated in Seoul, etc.). It can be similar to mail.

The second is a case of a navigation system in which the terminal itself has a function such as path search, but not through a specific device. In order to receive traffic information in real time, the navigation system should have a separate network access device such as an FM DARC (Data Radio Channel) traffic information receiver provided by MBC. In addition, the navigation system calculates a route, stores the driving route being guided, tracks traffic information changed on the driving route, calculates every predetermined period, and informs when there is a better route than the route being guided. Therefore, in the case of the current navigation system, a high-performance terminal capable of performing the functions described above has a problem of low marketability due to an expensive price.

In addition to the above-described problems, there is a more fundamental problem that the reliability of the traffic information itself is poor.

Accordingly, the present invention has been made to solve the above-mentioned problems, a method for providing traffic information that is necessary for the customer among the traffic information, and can provide the most reliable notice information to the customer in real time through the mobile communication network, It is an object of the present invention to provide a recording medium recording the apparatus and method thereof.

In addition, another object of the present invention is to provide a method, an apparatus for providing traffic information that can provide notice information to a corresponding terminal in real time when the notice information occurs on the provided driving route, and a recording medium recording the method.

In addition, another object of the present invention is to provide a method, apparatus, and a recording medium on which the method is provided for providing a re-discovered driving route corresponding to notice information.

Other objects of the present invention will become more apparent through the preferred embodiments described below.

Here, the stored information of the terminal may be any one of a phone number or an IP address.

In addition, the step of recognizing the terminal provided with the driving route associated with the notice information of the provided driving route, the step of recognizing the node or link ID of the map corresponding to the notice information; Searching for a driving route including the node or link ID among the stored driving routes; And extracting information of the terminal provided with the searched driving route.

The storing of the driving route and the terminal information may further include time information providing the driving route and speed information at the time of calculating the driving route.

In addition, recognizing a terminal provided with a driving route associated with the notice information among the provided driving paths may include: recognizing a node or a link ID of a map corresponding to the notice information; Searching for a driving route including the node or link ID among the stored driving routes; Determining whether each searched driving route passes the node or the link based on the time information and the speed information; And extracting terminal information corresponding to the driving route determined not to pass.

In addition, the traffic information may be transmitted by SMS, and may include a driving route calculated to correspond to the notice information. In addition, the traffic information includes a service ID, but receiving a re-routing request including the service ID from the terminal; Calculating a driving route corresponding to the notice information; And transmitting the driving route to the terminal.

According to the second aspect of the present invention for achieving the above object, it is tangibly embodied to be executed in the terminal to provide traffic information according to the received notice information including the service ID received from the driving route providing apparatus A recording medium on which a program can be read by the terminal, the recording medium comprising: outputting the notice information through a screen or a speaker; Transmitting the service ID to the driving route providing apparatus according to a driving route request input from a user; Receiving a new driving route from the driving route providing apparatus; And displaying the new driving route. The recording medium having the program recorded thereon is provided.

Here, the driving route request may further include current location information.

Hereinafter, a method and apparatus for providing traffic information according to notice information on a driving route provided in a preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings. The same or corresponding components will be given the same reference numerals and redundant description thereof will be omitted.

1 is a configuration diagram schematically showing an entire system for performing a method for providing traffic information according to notice information on a provided driving route according to a preferred embodiment of the present invention.

According to FIG. 1, the entire system includes a terminal 10 having a location acquiring means therein, a driving route providing device 30, and a traffic information center 50a, 50b, 50n, hereinafter 50.

In order to calculate the driving route, it is necessary to know the current location (origin information) and destination information. Therefore, the terminal 10 needs a position acquiring means for acquiring the current position coordinates, that is, the position information of the starting point. Currently, the most widely used location information acquisition method is a cell method using a GPS receiver, a base station of a mobile communication network, a repeater for a wireless network, and the like. Accordingly, the terminal 10 does not necessarily have to embed or mount a GPS receiver in order to acquire location information, and may acquire location information through a cellular method. It is obvious that other location information acquisition technology may be applied in the same manner as the GPS method and the cell method, and the GPS method can obtain the most accurate location coordinates in the current technology, and since it is the most commercialized technology, the GPS receiver using the GPS method will be described below. It will be described taking a terminal equipped with an example.

The terminal 10 refers to all terminals capable of data communication via wireless, such as a wireless LAN terminal, a Bluetooth terminal, a portable Internet terminal, as well as a mobile communication terminal including a PCS, a PDA, a smartphone, and the like. In particular, it is a terminal equipped with a navigation function or connectable with a navigation kit. Hereinafter, a mobile communication terminal equipped with a navigation function will be described as an example, but it will be further apparent through the following description that other terminals can be equally applied.

Each traffic information center 50 performs a function of collecting and distributing traffic information including notice information. Here, the notice information includes not only traffic accidents but also all traffic information for which traffic congestion is expected, such as construction of a road.

The traffic information center 50 transmits the collected traffic information to the driving route providing apparatus 30 in real time or at regular time intervals. In particular, when the notice information is transmitted, the driving route providing apparatus 30 may include identification information so as to recognize whether the notice route information is notice information. A separate identifier may be used for the identification information, and a method of presetting a value of a specific parameter of the provided traffic information may be used. In addition, a method of using the format of the notice information different from that of other traffic information may be used. In addition, it is apparent that the driving route providing apparatus 30 may apply the same method in which any traffic information is noticed information. The traffic accident and the road may be applied without any other identification information from the traffic information center 50. It is natural that traffic information such as construction may be set in advance as notice information, or the driving route providing device 30 may recognize notice information through the traffic information itself.

The driving route providing apparatus 30 makes a database of the traffic information received from the at least one traffic information center 50, and the received traffic information calculates (or calculates) the driving route according to the driving route request from the terminal 10. , Hereinafter referred to as calculation). In particular, when the traffic information received from the traffic information center 50 is yugo information, the driving route providing apparatus 30 not only stores the yugo information, but also an area associated with the yugo information of the driving route provided to the terminal 10 (hereinafter, referred to as “the yugo information”). When there is a driving route via the yugo region), the terminal 10 provides the yugo information, that is, the traffic information corresponding to the yugo information. Here, rather than transmitting the notice information to all the terminals 10 provided with the driving route via the yugo region, the information such as the speed of the customer vehicle at the time of providing the driving route, the providing time, the distance between the starting point and the yugo region, etc. It is determined whether or not they have passed through the yugo area, and do not send any notice information about the passed customers.

In addition, when the driving route providing device 30 provides the notice information to the terminal 10, the terminal 10 does not need to connect to the driving route providing device 30 so that the short message service (SMS, Short Message Service) and voice message.

In addition to a terminal that can receive messages through a phone number, such as a mobile communication terminal, a terminal without a phone number can receive a traffic information message regarding notice information to the terminal through an IP address that can uniquely recognize the terminal. send.

In addition, the driving route providing apparatus 30 may not only provide the notice information to the terminal 10, but may recalculate the driving route corresponding to the notice information, that is, not through the notice region, and provide the notice to the terminal 10. It may be. The new driving route may be provided by request from the terminal or uniformly together with the notice information when the notice information occurs.

In this case, when a new driving route is provided at the request of the terminal 10, the time for connecting the terminal 10 to the driving route providing apparatus 30 may be reduced, and the inconvenience of inputting related information may be eliminated. In addition, the driving route providing apparatus 30 may provide a new driving route corresponding to a service ID to a terminal requesting a new driving route through the service ID by providing a unique service ID when providing notice information. . That is, the driving route providing apparatus 30 stores all the driving route, the notice information, and the terminal information that were previously provided to correspond to the service ID. Alternatively, the new driving route may be calculated in advance, and the new driving route may be immediately provided through the service ID.

Hereinafter, the configuration of the driving route providing apparatus 30 and the function of each configuration will be described in detail with reference to FIG. 2.

2 is a functional block diagram schematically showing the configuration according to the function of the driving route providing apparatus according to an embodiment of the present invention, Figure 3 is to extract the driving route or the terminal information according to an embodiment of the present invention Figure is a diagram showing a driving path table for.

According to FIG. 2, the driving route providing apparatus 30 includes a transceiver 31, a traffic information database 32, a driving route storage 33, a driving route extracting unit 34, a message sending unit 35, and a service. The ID manager 36 and a driving route calculator 37 are included.

The transceiving unit receives traffic information including notice information from the traffic information center 50, or transmits and receives data for providing a driving route with the connected terminal 10.

The traffic information database (D / B, Data Base) stores traffic information received from the traffic information center 50. Typically, the traffic information is updated from the traffic information center 50 at intervals of a predetermined time (5 to 10 minutes). In addition, the traffic information stored in the traffic information database is preferably stored or deleted in a separate area after a certain period of time (for example, one day or six hours) stored. Since the traffic information used to calculate the driving route is valid only at the time of calculating the driving route, the previous traffic information is managed or deleted separately. On the contrary, the traffic information for the predetermined period may be stored in a separate storage device or a separate area, and the traffic information after a certain period may be stored in the traffic information database. Therefore, the driving route providing apparatus 30 may search for valid traffic information for calculating the driving route more quickly.

The driving route storage unit stores the driving route calculated and provided according to the driving route request from the terminal 10, and the driving route extracting unit receives the notice information from the traffic information center 50, and thus the driving route associated with the notice information. That is, the driving route via the yugo region is extracted from the driving route storage unit.

The driving route storage unit may store not only the driving route but also traffic information at the time of providing the driving route, and driving route calculation information regarding a traveling speed of a customer (terminal user).

The driving route extraction unit may extract the driving route from the driving route storage unit through the driving route table stored in the driving route extraction unit or the driving route storage unit.

Referring to FIG. 3, the driving route table includes a time at which the driving route is provided to the terminal, terminal information, and a storage address of the driving route storage unit in which the driving route is stored. It is preferable to delete the driving route after a predetermined period from the providing time in the driving route table, delete the driving route stored in the driving route storage unit, or store the driving route in a separate storage device (for storage). In order to extract the driving route faster, only the driving route for a certain time is stored.

The terminal information is information of a terminal that provides a driving route, and can uniquely distinguish a corresponding terminal such as a telephone number or an IP number, and is information of a terminal that can provide traffic information including notice information or driving route.

Hereinafter, a method of extracting the driving route corresponding to the notice information from the driving route storage unit will be described.

Road maps are typically represented by nodes and links between nodes in each region. That is, the notice information includes information about a node or a link of the notice region on a map. Therefore, first, a driving route including a node or a link of the yugo region is extracted. Subsequently, each extracted driving route calculates a difference from the current time using the time information provided to the terminal 10, and the current driving height is determined using the driving speed information of the terminal user (ie, the customer) at the time when the driving route was provided. Determine if you passed the area. The driving speed information may be received from the terminal 10 or may be inferred through the traffic information of the point where the customer is located.

(Current Time-Driving Route Providing Time) * Calculate driving speed = distance traveled, distance between starting point and Yugo area = Yugo point distance.

As a result of the calculation, in the case of 'moved distance> distance of yugo point', it is determined that the passage has passed through the yugo area, and the driving route is not determined as a service target. In the case of 'moved distance <distance of yugo point', it is determined as a service target and terminal information providing the corresponding driving route is extracted.

The message sending unit performs a function of transmitting traffic information corresponding to the notice information to the corresponding terminal through the extracted terminal information. The transmitted traffic information may be transmitted to display an image of the yugo region and the yugo region on the driving route map. However, as described above, the traffic information is preferably transmitted by SMS to minimize the amount of data.

The service ID manager performs a function of issuing and managing a service ID. The service ID is included in the traffic information when the message sender transmits the traffic information. The service ID is received from the terminal 10 receiving the driving route re-request according to the notice information, and the previously provided driving route (origin and destination). Information) and the notice information and the terminal information are linked so that the driving route may be recalculated and transmitted to the corresponding terminal 10.

Therefore, the service ID management unit temporarily stores the issued service ID, the provided driving route and notice information, and terminal information.

The driving route calculation unit searches for the optimum route through the starting point and destination information and the traffic information previously received from the traffic information center 50 existing between the starting point and the destination, in response to the driving route request or re-request. A function of calculating a driving route including the reflected map is performed. The technology for searching a route using traffic information is still actively developed, and more accurate search techniques will be developed afterwards. It is obvious that all these route search techniques can be equally applied to the traffic information providing method according to the present invention. Do.

Hereinafter, a process of providing traffic information according to notice information on a driving route according to the present invention will be described with reference to the drawings.

4 is a flowchart illustrating a process of providing a driving route according to an exemplary embodiment of the present invention.

Referring to FIG. 4, in operation 410, the driving route providing apparatus 30 receives traffic information from at least one traffic information center at any time. The traffic information center 50 may periodically transmit traffic information at a predetermined time, or may transmit in real time when new traffic information such as notice information occurs.

In step 420, the terminal 10 requests the driving route by providing the driving route providing apparatus 30 with starting point information, which is a current location coordinate through the GPS receiver, and destination information such as a place or a building of the destination. The driving route request message including the departure point information and the destination information may be transmitted, or the corresponding service may be requested by accessing the driving route providing apparatus 30.

In operation 430, the driving route providing apparatus 30 calculates the driving route from the starting point to the destination. Here, the driving route providing apparatus 30 may calculate a driving route that can arrive in the shortest time by determining a smooth traffic situation based on the traffic information previously received from the traffic information center 50 among various routes from the starting point to the destination. have. In addition, the shortest driving route may also be calculated and provided to the terminal 10 without considering the traffic information. Therefore, the customer may select and use the driving route according to the shortest driving time and the shortest distance, or may select and request the driving route upon request.

In operation 440, the driving route providing apparatus 30 stores the calculated driving route and the phone number, which is the terminal information, and transmits the driving route to the terminal 10 in operation 450.

Thereafter, after a predetermined period of time, the stored driving route and the terminal information are deleted in step 460. The reason for deleting the driving route is to avoid searching for the unnecessary driving route when searching for the driving route for providing the notice information to the terminal 10 according to the received notice information. Here, the storage path of the driving route and the terminal information may be differently applied according to the length of the driving route, and may be set to the same period (for example, 6 hours) uniformly for convenience of management.

Hereinafter, referring to FIG. 5, when the notice information is received from the traffic information center 50 in the driving route providing device 30, a process of providing traffic information about the notice information to the terminal 10 will be described.

5 is a flowchart illustrating a process of providing notice information to a terminal in a driving route providing apparatus according to an exemplary embodiment of the present invention.

Referring to FIG. 5, the yugo information is received from the traffic information center 50 in step 510. In step 520, the node or link of the yugo area is recognized, and in step 530, the yugo area of the yugo area is provided. Search for driving directions that include nodes or links.

In operation 540, it is determined whether a driving route related to the search result notice information exists. If the determination result exists, in step 550, it is determined whether the customer who has received the driving route passes through the yugo region. As described above, the determination method may be determined based on the speed information of the customer at the time of providing the driving route, the driving route providing time information, and the like.

If the determination result does not pass through the yugo area, in step 560 the traffic information corresponding to the yugo information is transmitted to the terminal 10. That is, the notice information may be transmitted as the traffic information, or may include a service ID for providing a new driving route according to the notice information or a new driving route according to the customer's selection.

Hereinafter, referring to FIG. 6, as the driving route providing device 30 provides notice information including a service ID to the terminal 10, a process of providing a new driving route by the customer's selection will be described. .

6 is a flowchart illustrating a process of providing a new driving route corresponding to notice information according to an exemplary embodiment of the present invention.

Referring to FIG. 6, in step 610, the terminal 10 receives notice information from the driving route providing apparatus 30. Therefore, the notice information received in step 620 is output through a display device (if a text or image) or a speaker (if a voice message). Here, the service ID received together does not need to be output, but is temporarily stored in the memory of the terminal.

In step 630, the terminal 10 determines whether the command input from the user (customer) is a command according to the driving path re-request or the notice information output ending command. When the driving path re-request command is input, the new driving path is requested by connecting to the driving path providing apparatus 30 and providing the service ID received and stored in operation 640. Here, the terminal 10 may measure and provide current location information, that is, location information of a new starting point, through a GPS receiver.

When the re-request of the driving route is not input, the output of notice information is terminated in step 645.

Here, the re-request of the driving route may be automatically performed without the user's judgment.

In operation 650, the driving route providing apparatus 30 recognizes the driving route and notice information through the service ID, and calculates a new driving route in operation 660. In other words, an optimized driving route that does not pass through the yugo area is calculated.

In step 670, the new driving path is replaced with the previously stored driving path and stored, and in step 680, it is transmitted to the corresponding terminal.

FIG. 7 is a diagram illustrating request information provided on a screen of a terminal according to an exemplary embodiment of the present invention and request and provision of a driving route according to the notice information.

In the first screen, when the notice information is received, the route guide screen disappears and the notice information is displayed, or the notice information is displayed in a pop-up message format. Of course, when the notice information is received by voice, the notice information may be heard through the speaker.

As the user presses the confirmation button, the request for the driving route is re-requested to the driving route providing apparatus 30 through the service ID received and temporarily stored together with the notice information.

The second screen is a screen while the terminal 10 is connected to the driving route providing apparatus 30 to receive a new driving route, and the third screen shows a new driving route provided from the driving route providing apparatus 30.
