Description

How to provide traffic information {TRAFFIC INFORMATION PROVIDING METHOD}

The present invention relates to a traffic information providing method, and more particularly, to a traffic information providing method for providing real-time traffic information according to a two-way wireless mail message (full text) of a user terminal such as a mobile communication terminal, a personal mobile terminal, a PDA, and the like. will be.

In general, the driver wants to obtain fast and accurate traffic information such as the desired highway, inner city roads, national roads, etc., that is, traffic conditions, traffic control conditions, the time required from the origin to the destination, and the average speed. On the other hand, the best information is obtained by using the minimum cost of communication fee and information fee.

In particular, in the case of Korea, the number of weekend trips is increasing due to the five-day workweek system, and traffic volume is rapidly increasing at a certain time, and drivers who are inexperienced or do not know road conditions have a high probability of traffic accidents. Infrastructure utilization environment is becoming relatively easy.

In such a situation, there are various channels for providing traffic information to the driver.

For example, Korea Highway Corporation ARS (1588-2505) is difficult to obtain the desired information due to the comprehensive traffic information provided. In other words, the characteristics of the ARS to listen carefully to the time-passing voice and the user's point of use is inconvenient, it takes a relatively long time to listen to the information they want, 20 won per 10 seconds There is a difficulty in storing the information listened with the information usage fee.

In addition, other ARS (e.g., sheath, telephone service 060-800-8002) cost 200 won / 30 seconds (tax not included), while the voice connection and text-to-speech (TTS) functions are in operation. It is difficult to hear machine sounds in noisy places, and the lack of information storage can also be pointed out as a disadvantage thereof.

In the case of the traffic information providing service of the wireless Internet, it is necessary to pay an expensive mobile carrier connection fee (call fee and information transmission fee), and the depth of the information is deep and rich, but the data usage is low and it is uneconomical.

In the case of traffic information providing services using navigation, traffic information, maps, and living services corresponding to the basic monthly fee can be provided, but an expensive and special navigation system must be installed in the vehicle, and an uneconomical disadvantage that requires a separate system upgrade is required. There is this.

A technique using a bidirectional text message service and a database processing technology according to the prior art is disclosed in Korean Patent Publication No. 2001-0107869.

This publication No. 869 technology is a route bus guidance system to a destination using a mobile phone text communication, and a method thereof, as shown in FIG. 1, in which a user stops a name of a current location (or an identification code value) on a user terminal 10. ) Information and destination zone information is formed into an SMS text message and transmitted to the information system, and when the information is received by the information receiver 30a of the information retrieval apparatus 30 via the communication station 20, the information data 30b and Data analysis and processing for classifying caller information 30c and withdrawing information, and searching for information in a database based on the retrieved information data 30b and calculating and analyzing the retrieved information to select an optimal route bus number. In step 40a, the caller's telephone number and the selection data shown in the caller information 30c are added so that the selection data is transmitted to the user terminal 10 via the communication station SMS system 50. It is characterized in that the configuration including the transmission format configuration step (30b).

Here, the bidirectional text service is a mobile switching center in which a short message service center (SMSC) is a signaling point of a short message service, a database, an interface, and a wireless network element based on an intelligent network (IN) access. (MSC: Mobile Switch Center), Home Location Register (HLR) refers to a service that sends a text message in both directions using.

Database processing technology refers to a general database construction technology for storing, assembling, sorting, searching, and extracting a database corresponding to an interface.

That is, the conventional route bus guide system and its guidance method are for obtaining simple information using a conventional bidirectional text service and database processing technology, and are not sufficient to provide road traffic information on existing complex road conditions. In order to progress to such road traffic information service, the following problems exist.

That is, due to the nature of the road traffic information, road traffic information for each section from the region where the user is located to the destination to be moved, or traffic information for each section of the directional road that the user is currently moving to, or a road other than the road where the user is currently moving The information on the detour road should be provided in real time, so it will not be comparable as an information service.

However, like the conventional route bus guidance system and its guidance method, the user simply provides the route guidance information to the user by using a bidirectional text service and database processing technology, and provides a convenient road traffic information service. Convenience, other differentiation and economic feasibility according to a specific method are absent.

Meanwhile, as another conventional technology, a real time traffic information providing system is disclosed in Patent Publication No. 2003-0020508.

This public number '508 technology is a system that provides traffic information in real time through a user terminal 20 such as a general telephone, a mobile phone, a PDA, and a map having a unique number for facilities such as main roads, intersections, and buildings. It includes a book and an operator server connected to the user terminal through a wired or wireless network and equipped with an algorithm for recognizing and outputting a corresponding service by recognizing the unique number of the atlas.

Here, the algorithm for searching for and outputting the corresponding service means that the operator server receives the unique number of the departure point and the unique number of the arrival point, and obtains traffic information, movement route information, and public transportation information between the departure point and the destination point according to the selection of the service code. Alternatively the transfer process.

However, the publication number '508 technology requires a dedicated map to which a unique number is mapped in order to check the location of the starting point and the location of the destination, and at the same time, the page number of the map, the block number to which the starting point belongs, and the location number in the block Inconvenience to input the unique number of the starting point and the unique number of the destination of the same format while viewing the map.

Despite the inconvenience of using a map that requires a combination of numbers, it is necessary to manually input the source number, the destination number and the service code after accessing the service. There is an economic disadvantage to have an additional bar code scanning device in its terminal, this point is a non-economic disadvantage similar to the traffic information providing service using the navigation.

Therefore, in the operating system or operation method that services road traffic information in real time, the user can easily and conveniently convey the road traffic information demands desired by the user wherever he or she is located, and accordingly the desired road traffic Accurate and easy information can be obtained by maximizing service usability and convenience and using a characteristic computer network.

However, since the public number '508 technology directly inputs its own location information using a complex code, if searching the map itself is inconvenient to use, one complex unique number is found one by one on the found map. The difficulty of writing the full text is very large.

In addition, in the above-mentioned publication number '508 technology, since only a source number and a destination number and a service code are inputted, the operator server does not enter any information on the direction in which the user intends to proceed. Information arbitrarily selected from any one of information, movement route information, and public transportation information is transmitted to the user, and thus, road traffic information that is not completely related to the user's intention is transmitted to the user's terminal, or desired and desired information is not transmitted. Since the information is not mixed and transmitted, the reliability of the transmitted information is less reliable. Such information is no different from the existing ARS road traffic information service.

In conclusion, since the publication number '508 technology depends on the feasibility of providing the service in the preparation of the atlas, there is a limit to simply using the actual road traffic information service.

In addition, the publication number '508 technology does not mention any technology for providing shortcuts or repetitive information, so that every time you travel on a routinely repeated road, such as commute, the complex starting number and destination number and service It is inconvenient to enter the code every time.

The present invention is to solve the problems of the prior art as described above, according to the user's information requirements, including the unique number and the progress direction separator and distance separator, the highway corresponding to the customer location, the inner city road, national national highway, After arranging the traffic information of the national road bypass, and replying back to the customer by SMS, the purpose is to provide a traffic information providing method that can provide users with easy and convenient and economical real-time customized road traffic information. have.

The professional menu module 63 and the professional writing module 64 stored in the wireless terminal 60 are programs similar to a program wizard function, and the user selects road names, directions, information on the starting point, and destination information according to the program menu guide. Then, the information request message is constructed and created using the code value of the index associated with the selected menu corresponding to the normal encoding process, and the operating system of the present invention is transmitted through the mobile communication company 90 according to the selection signal input of the send button. 100) is responsible for the transmission.

The speech recognition module 62 is constructed by constructing the professional menu module 63 and the professional writing module 64 into a voice tree index structure (which can be created by Voice Web, Voice Web Builder program, etc.), and encoding the result of speech recognition. It prepares the information request text and transmits the information request text written according to the voice command.

The external device 70 stores data when the wireless terminal 60 does not allow the use of the data storage space 61, the voice recognition module 62, the professional menu module 63, and the professional writing module 64. It is used as a means for storing and executing the space 61, the voice recognition module 62, the professional menu module 63, the professional writing module 64. The external device 70 is a hardware and software corresponding to a conventional wireless terminal interface, and has a circuit configuration interworking with the wireless terminal 60. In addition, the external device 70 may be used as a means for storing or executing the game 65 having a large data.

The personal computer terminal 80 is a client module of OCX (OLE custom control) format for performing the above-mentioned hotkey setting for receiving road traffic information, information receiving reservation setting, and setting of a favorite function, JAVA, CGI, PHP, etc. It has an interface for a normal web browser that is programmed in the web programming language. The interface for the web browser is interlocked with the website server 130 described below through the Internet network 81.

The mobile communication company 90 is provided with a base station 91, a general mobile communication system, a location information system (LBS), and a location information DB 92.

The operating system 100 includes a traffic information gateway server 110 (hereinafter referred to as a 'GW server'), a traffic information database server (120: referred to as a traffic information DB server below), and a traffic information website server 130. Has

The traffic information website server 130 provides a wired / wireless Internet service to a user, a wired web site and a wireless WAP capable of managing user members, various additional services, information, billing, usage history, and personalized service management. It has a site and a web DB.

To this end, the traffic information website server 130 corresponds to a web / wap engine 131 programmed in a web programming language, and a full text created and stored by a web / wap site in advance in order to obtain desired road traffic information. Receiving shortcut key management module 132 to set a shortcut to perform a normal bookmark function and the road traffic information push module responsible for setting the information receiving reservation for transmitting the road traffic information to the member regularly or irregularly Has

WebDB records and stores 'user information DB table', 'traffic information service log data table', 'payment service log data table', and 'shortcut key / favorite / reservation information data table'.

The traffic information DB server 120 includes a highway traffic information DB 121 for implementing a real service, a national road traffic information DB 122, and a road traffic information DB 123 in a downtown area (including metropolitan city).

Here, the traffic information DBs 121, 122, and 123 are updated periodically (5 minutes) from at least one source traffic information provider system.

The traffic information DB server 120 uses various traffic information DBs 121, 121, and 123 to name roads, road numbers, direction of travel, average speed for each section, traffic conditions, traffic control, expected time, national route detour information, and starting point. It builds a processed traffic information DB including at least one of distance, guide information, and breaking information, or combines the processed traffic information DB in real time.

Table 1 is text information on the highway provided from the source traffic information provider, and will be described as an example of configuring the traffic information DB. Character information includes route code and text and other information.

Accordingly, the traffic information DB server 120 extracts the data required by the present invention by a predetermined algorithm from the contents updated as described above. Here, the predetermined algorithm is a series of methods for extracting the road name or place name or the direction of travel or distance indication (number identified by 'K') as an index, and then recording and storing the provided character information in a predetermined order. Say

Table 2 below is an embodiment of the highway character information DB table.

In addition, the traffic information DB server 120 configures, records, and stores the traffic information DBs 121, 122, and 123 by the predetermined algorithm described above. For example, the traffic information DBs 121, 122, and 123 may include general information DB tables such as road names (section names); An average speed information DB table between sections of the road; An intersection point (branch point) information DB table which records and stores the contact point of the intersection point between X coordinates and Y coordinates in a distance unit Km; A highway unique number DB table; There are various types of traffic information related tables, including 'user LBS DB table' which records and stores the current location information (X coordinate value, Y coordinate value) of each user's calling terminal obtained by accessing the location information system of the mobile carrier. do.

Table 3 is an example of an 'intersection (branch point) information DB table between roads'.

The direction of highway number '1' to '50' corresponds to '[Singal Junction] Busan starting point 397K', and the direction of '50' to '1' corresponds to '[Singal Junction] Incheon starting point 42K'.

The DB Design Criteria periodically summarizes the traffic information provided by KNOC, but indexes the distance from the starting point of the road based on the starting signboards marked around the median for the section of the highway.

In addition, in the present invention, in order to enable traffic information to be searched by distance, distances by sections according to names are matched, and distances between information search origins of each highway are set based on the origin of each highway. In addition, when the user inputs and transmits the distance between the departure point and the arrival point, the present invention does not use the location information DB 92 of the location information system, but performs matching with the area name according to the location.

As such, the traffic information DBs 121, 122, and 123 of the present invention are constructed to be inquired by setting the local name according to the distance position as a condition, and the inquiry data (coordinates) of the location information DB 92 of the mobile communication company 90 is coordinated. It can be constructed by matching the value with the name of the highway.

On the other hand, the user location confirmation (secure) method of the present invention is as follows. First, GPS (location information using satellite) is used. That is, in the case of a terminal with a built-in GPS chip, the GW server 110 of the present invention through the mobile communication company, even if the user does not directly input any information value that means his location at the time of writing the information request message. It can be confirmed at, and only accurate and clear road traffic information corresponding to the user's location can be delivered to the user.

In addition, the operating system of the present invention uses the location information DB 92 in conjunction with the location information system of the mobile communication company (90). Here, the GW server 110 inquires or extracts the location information of the user corresponding to the originating identifier in the location information DB 92 in association with the location information DB 92, and uses the location information of the user thus obtained. The road traffic information from the current location of the user to the destination to be moved is provided to the user's wireless terminal 60.

In addition, a starting point display panel (distance display panel) is used. In the case of a highway, a distance display plate is shown around the central separator indicating the distance from the origin in km. In this case, when the user enters the highway number and the distance from the starting point, the GW server 110 checks the location of the user.

As shown in FIG. 3, the GW server 110 basically provides a real PPP / to provide a highway traffic information inquiry service, a road traffic information inquiry service within a national road and a downtown area, and a national road bypass information service that bypasses a delayed or congested highway. It uses the Point to Point Protocol / Serial Line Internet Protocol (SLIP) method and uses the bidirectional text service mentioned in the prior art as the basic professional transmission infrastructure based on the intelligent network (IN) access.

To this end, the GW server 110 is a computer program SMS receiving module 111, DB interworking module 112, professional error determination module 113, professional analysis module 114, information extraction module 115, full text creation And a memory for storing the module 116, the SMS transmission module 117, and the LBS interworking module 118, and a processor coupled to the memory to execute a program.

In the above program, the SMS receiving module 111 receives a calling identifier and an information request message corresponding to the calling terminal (where the calling terminal is a wireless terminal having a reference numeral '60' of FIG. 2) from the calling exchange. Here, the calling identifier refers to a mobile identification number (MIN), a cellular telephone number (CTN), etc. of the calling terminal.

In addition, the information request message means a data value consisting of a forward direction separator, a starting distance separator, a destination distance separator, and a complex frequency code (DTMF) signal representing a unique number and a distance, that is, a letter / number / symbol, and a number of a wireless terminal. Can be entered through the keypad and special character input window.

In other words, the information request message is written, judged, recognized, and interpreted (analyzed) according to a predetermined rule.

For example, a rule made in advance by an information request specialist will be described as follows.

① [unique number] [progressor separator].

② [unique number] [going direction separator] [originating distance separator] [distance] [destination distance separator] [distance].

③ repeating or selective arrangement of the above ① and ②.

Here, the unique number is a number within 3 digits or the current highway unique number value, the direction delimiter is '*', '#', the starting distance separator is '/', the distance is the distance from the starting point consisting of numbers, and the destination distance separator is '//'to be. In addition, two or more highways may be used, and the traveling direction of the highway to be used for the first time when inputting a starting distance value may be omitted (blank input).

DB interworking module 112 is a road name, road number, direction, average speed for each section, traffic conditions, traffic control, expected time, national road bypass information, member information, billing information, use information, etc. in the traffic information DB server It is responsible for processing and managing various traffic information DBs.

The professional error determination module 113 compares the information request message received by the SMS reception module 111 with the specialized text, and checks whether there is an error.

For example, when the information request message '1 # / 300 // 400' is input to the GW server 110 from the user's wireless terminal, the professional error determination module 113 may proceed with a direction delimiter ('*' or '#'). ), The first data (number: 1) with the forward direction separator is 3 digits or less, and if there is the first data in the data of the 'highway unique number DB table', there is no error information. Judging from the requirements.

The professional interpretation module 114 also plays a role in recognizing and interpreting (analyzing) the data of the information request specialist and its arrangement based on the professional format.

For example, when an information request message '1 # / 300 // 400' is input to the GW server 110 from the user's wireless terminal, the full text interpretation module 114 performs the following process.

In other words, '1' is recognized as 'H1' which is a unique highway number (Freeway_code), and '#' is recognized as 'N' (north direction) referring to the direction of the highway corresponding to the unique number among the west and north directions. do. For reference, Gyeongbu Line 1 extends north and south. '/ 300' is recognized as 300Km based on Busan starting point, and '// 400' is recognized as 400Km based on Busan starting point. Therefore, the professional analysis module 114 is the information request of the '1 # / 300 / / 400' from the highway No. 1 [Seoul direction] from 300km? After analyzing the traffic information up to the 400Km section, the analysis results are transmitted to the information extraction module 115.

In another example, when the information request message '1 * 50 * / 400 / / 120' is input to the GW server 110 from the user's wireless terminal, the specialized analysis module 114 is a '1' expressway unique number It is recognized as 'H1' which is (Freeway_code), and '*' is recognized as 'S' (south direction or Busan direction) referring to the direction of the highway corresponding to the unique number among the east direction and the south direction. In addition, '5' is recognized as 'H50', which is the highway unique number (Freeway_code), and '*' is referred to as the 'E' (east or Gangneung direction) referring to the direction of the highway corresponding to the unique number among the east and south directions. To be recognized. In addition, '/ 400' is recognized as the distance from the starting road to the starting point, '// 120' is recognized as the distance from the starting point of the final road, where the expert analysis module 114 to interpret the direction for the intersection Produce temporary constructs such as

That is, the first temporary phrase is initially written as '1 * / 400 // X', and the full-text analysis module 114 displays the road indicated by 'H1' and the 'H50' in the 'intersection point' DB table. The X coordinate value, '397', is extracted from the contact coordinate values of the road, and this is input to 'X' to complete a first temporary phrase such as '1 * / 400 // 397'.

In the same way, the second temporary statement is initially written as '50 * / Y // 120 ', and the expert analysis module 114 uses the road and' H50 'indicated by' H1 'in the' intersection (junction) DB table '. The Y coordinate value '42' is extracted from the contact coordinate values of the road indicated by, and the second coordinate phrase such as '50 * / 42 // 120 'is completed by inputting the' Y 'into' Y '.

Thereafter, the full text analysis module 114 recognizes and interprets the completed first and second temporary phrases, respectively, and transmits the analysis result to the information extraction module 115.

The information extraction module 115 creates an input expression of DB quality as an analysis result value received from the information analysis module 114, and the road name, road number, and driving direction, which are the traffic information desired by the user in the DB tables shown in Tables 2 and 3 above. It is a kind of program that extracts at least one traffic information among the average speed, traffic condition, traffic control, expected time, national route detour information and outputs the result value.

The professional writing module 116 plays a role of creating a road traffic information professional response message (hereinafter, referred to as a 'professional response message') in response to a customer's progress direction based on the result value.

The SMS transmission module 117 transmits the created professional response message to the calling terminal corresponding to the calling identifier.

The LBS interworking module 118 works in conjunction with the location information system of the mobile communication company, and performs the function of inquiring and extracting information on the location information of the user's calling terminal. The location information value is converted by the LBS linkage module 118 to the nearest point closest to the highway to be used for the first time, and the proximity point is converted into a distance from the starting point.

The GW server 110 provides national road bypass information consisting of items of national road number, traffic conditions, traffic control information, average speed, and time required for a user who is a customer in a national road bypass information service according to a highway delay and congestion.

The order of national bypass information service is as follows. According to the traffic information providing method of the present invention, the user transmits the contracted information request message to the operation system, and receives a specialized response message containing the traffic information corresponding thereto. The user configures a contract information request for the expressway wants traffic information to a specific number connected to the GW server 110. By the program operation of the other modules including the SMS receiving module 111, the GW server 110 receives the information request message, and transmits a professional response message containing the corresponding traffic information to the wireless terminal according to the received message. do. The user checks the contents of the received traffic information, grasps the status of the delay and congestion of the relevant highway, and then requests the detour information again using the normal 'reply' function, that is, the callback message function. Press the button), a professional response message containing the national road bypass information is transmitted to the user's wireless terminal in the same manner as described above.

Hereinafter, the traffic information providing method of the present invention will be described.

As shown in FIG. 4, the user starts a wireless mail message service (including a short message) on the user terminal without being connected to the mobile communication company's wireless communication network (S10).

Using the user terminal, a full text request information is prepared by using a code direct input method, a voice recognition / command input method, a menu selection input method, and an external device (S11).

In other words, the voice recognition / command input method is a voice recognition / command input method of the information request writing method.The code direct input method uses a numeric pad and a special character input window of a wireless terminal. Or using a specialized menu module (professional writing module) downloaded and installed from a wireless Internet swap site, and the method using an external device includes a numeric pad, a special character input window, a selection menu, a voice menu, a wireless terminal interfaced with an external device. Use a touch screen method.

Hereinafter, the description will be made based on the code direct input method.

First, when a user uses a single highway, the corresponding highway number is input, and a full text is written along with the direction delimiter (*, #) and transmitted. Here, the progress direction separator may give meaning to the road construction policy direction. For example, '*' is a direction separator for east and south directions, and '#' is a direction separator for west and north directions.

For example, when a user writes the information request message '1 *' in his wireless terminal, '1' means Gyeongbu Expressway, and '*' means south direction, that is, Busan direction. Is a specialized information request for Busan direction of Gyeongbu Expressway. In this case, the GW server interprets the data and arrangement of the information request text in the above text format to analyze the user's intention.

Meanwhile, '*' may be east or south depending on the type of highway. That is, when a user writes the information request message '50 * 'on his wireless terminal,' 50 'is the Yeongdong Expressway, and' * 'is the east direction (Gangneung direction).

In addition, when a user uses two or more highways, the information request text may be prepared by sequentially inputting highway numbers to be used sequentially with a direction delimiter.

In this case, the information request telegram takes the form of '1 * 50 *'. Here, '1' is the Gyeongbu Expressway, '*' is the south direction, '50' is the Yeongdong Expressway, and '*' is the east direction. In this case, it is interpreted as a request for road traffic information from Busan (South) to Gyeongbu Expressway, and then to Gangneung (East) of Yeongdong Expressway via Singal Junction.

As another example, '1 * 50 * 55 *' is a specialized information request for Gyeongbu Line (Busan direction), Yeongdong Line (Gangneung direction), and Jungang Line (Busan direction). Here, '1', '50', and '55' are highway numbers determined by the Korea Highway Transportation Corporation.

Meanwhile, the traffic information DB server of the present invention periodically updates and stores the traffic information database from various traffic information provider systems, and processes the stored external traffic information database to process road names, road numbers, direction of travel, and average speed for each section. , To build a processed traffic information database including at least one of traffic conditions, traffic control, expected time, national road bypass information (S20).

The GW server receives the origination identifier and the information request message (S21).

As described in detail above, the GW server determines whether there is an error in the information request message using the specialized error determination module (S22). If there is an error in the information request message, a process of transmitting the message of a specialized configuration error message to the user's wireless terminal is performed.

Meanwhile, as described in detail above, the GW server recognizes and interprets the data of the information request message and the arrangement thereof sent by the user using the specialized analysis module (S23).

At this time, the professional interpretation module determines the presence or absence of the source information, such as the source separator from the information request full text (S24).

If there is no starting point information, the LBS interworking module accesses the mobile communication company's location information system and acquires the user's current location information (X coordinate value, Y coordinate value) corresponding to the user's calling terminal, DB table 'is stored (S25).

Thereafter, the full-text analysis module 114 analyzes the direction of the intersection point described above in detail to generate a temporary phrase, and displays the position information (X coordinate value, Y coordinate value) of the 'intersection point (DB) DB table' on the electronic map. The distance is converted to the X coordinate distance or the Y coordinate distance, or the distance from the starting point of the road closest to the user's location is converted, and the temporary phrase is completed using the converted result.

The information extraction module 115 of the GW server transmits the analysis result or the completed temporary phrase analyzed through the above steps to the information extraction module 115, inputs the DB query input expression into the traffic information DB server, and the traffic information DB. The server searches for any one of the highway traffic information DB, the national road traffic information DB, and the road traffic information DB in the urban area (including metropolitan city), including the service traffic information DB (S26).

The GW server extracts the information corresponding to the information request message from the generated result value after the search (S27), and writes the professional response message corresponding to the customer's progress direction based on the extracted result value and the information. It transmits to the calling terminal corresponding to the identifier (S28).

5 shows data values transmitted between the user's wireless terminal 60, mobile communication company 90, GW server 110, traffic information DB server 120.

Here, the wireless mail message is a request for information consisting of the user's mobile number and letters / numbers / symbols, the user's mobile number means the calling identifier.

In addition, the full text delivered by the GW server 110 to the traffic information DB server 120 refers to a DB query for outputting a result.

In addition, the wireless mail message transmitted from the GW server 110 to the user's wireless terminal 60 is a professional response message, and includes a communication situation, traffic control, average speed, and time required.

Hereinafter, the method of using or using the road traffic information service of the present invention described above will be described in detail.
