2. Description of the Related Art Conventionally, a road traffic information providing service has been provided in which various kinds of road traffic information are provided to a user by voice using an existing telephone and a public communication line network. Such services are provided by, for example, the Japan Road Traffic Information Center and the Metropolitan Police Department.

The road traffic information providing service provided by the Japan Road Road Traffic Information Center is provided by manual response. Specifically, an operator who answers a telephone call from a user is arranged in the central center. When the operator calls from the user,
The road traffic information of the road desired by the user is selected from the road traffic information previously obtained by the central center and explained by voice. The road traffic information obtained by the Central Center is
There are traffic closures and traffic jams.

On the other hand, the road traffic information providing service by the Metropolitan Police Department, unlike the above, provides the service by automatic response. Specifically, in the central center that provides information,
A voice synthesizer capable of generating various road traffic information by voice and a line control unit (NCU) are provided. Then, the voice synthesizer is always in the voice output state.

In this state, when the user makes a call, the line control device automatically detects this and connects the line with the user. As a result, the user can obtain the road traffic information generated by voice from the voice synthesizer from the handset.

[0006]

However, the above (goods)
In the road traffic information provision service by the Japan Road Traffic Information Center, the operator needs to listen to the contents of the road traffic information desired by the user and search for information that matches the contents, so the user actually wants the road traffic information. There was a problem that it took time to get. In addition, there is a problem in that it requires manpower because an operator who receives a call must be arranged. Further, since the only road traffic information that can be provided is information on traffic closures, traffic congestion, etc., there is a problem that the service content is limited.

Further, the road traffic information providing service provided by the Metropolitan Police Department provides some road traffic information in a relatively wide area such as the whole area of Tokyo. For this reason, if the user cannot obtain the effective information of the desired area, the user is required to pay a useless telephone charge, which causes an unnecessary burden on the user. . Further, since the voice synthesizer is constantly in the reproduction state, the user usually obtains road traffic information from the middle. In other words, there is a problem that you have to wait until you return to the beginning because you rarely get information from the beginning.

[0008] Therefore, an object of the present invention is to solve the above-mentioned technical problems and utilize existing telephones and public communication networks to provide effective road traffic information to users at low cost.
Moreover, it is to provide a traffic information providing system by voice guidance that can be provided promptly.

Portions overlapping the description in FIG. 4 will be omitted.

Referring to FIG. 5 (a), when the user sends the user number U, the central unit 2 judges whether or not this user number is registered, and as a result, the user number U is registered. If U is not registered, the central unit 2 automatically disconnects the line. At this time, the guidance voice such as "Your number is wrong" or "Please try again" is sent to disconnect the line.

On the other hand, when the user number U is registered and the personal identification number is next transmitted from the user, the central unit 2
Then, it is judged whether or not this personal identification number is registered,
As a result, if the personal identification number is not registered, the central unit 2 automatically disconnects the line after the guidance voice "Your number is incorrect" is sent out, as in the above case. .

As described above, according to the traffic information providing system of the present embodiment, the user can obtain only the desired road traffic information, so that the line connection time with the central unit 2 can be shortened. Moreover, since this road traffic information can be obtained through the existing telephone 1, it is not necessary to purchase a special device or the like. Therefore, the financial burden on the user can be minimized.

FIG. 6 is a block diagram briefly showing the configuration of the traffic information providing system according to the second embodiment of the present invention. The traffic information providing system according to the second embodiment is applicable when receiving road traffic information from a vehicle, and uses an automobile telephone and a car telephone communication device provided in the vehicle. In the vehicle, in addition to the car telephone communication device 20 and the car telephone corresponding to the telephone 1 in the first embodiment, the road map 4 in which the same point code number as in the first embodiment is described, and the vehicle And a navigation device 21 for detecting current position data of the vehicle.

More specifically, the navigation device 21 includes a position detecting section 22 for detecting the current position data of the vehicle, a memory 23 as a third storing means, a converting section 24 as a converting section, and an adding section as an adding section. It is composed of 25. The position detection unit 22 is configured to detect the current position data by a map matching method using the road map data stored in the road map memory 26 (for example, see Japanese Patent Laid-Open No. 64-53112). The detected current position data is composed of the mesh number and the latitude / longitude attached to the mesh obtained by dividing the road map into a plurality of parts. In the memory 23, the mesh number, the latitude / longitude, and the point code number described in the road map 4 are stored in association with each other. The conversion unit 24 converts the current position data detected by the position detection unit 22 into the point code number described in the road map 4, and at this time, the conversion operation is performed by referring to the memory 23. . Since the point code number converted by this conversion unit 24 corresponds to the current position data of the vehicle,
It corresponds to the origin point number O. The addition unit 25 sends the user number U, the service number S, and the destination point number D sent from the mobile phone 1 to the origin point number O converted by the conversion unit 24.
Is added to output to the car phone communication device 20. In the present embodiment, the navigation device 21 includes a memory 23, a conversion unit 24, and an addition unit 25.
Although the configuration including the above has been described, for example, a configuration including a modem including the memory 23 or the like may be connected to the existing navigation device 21.

The operation of each device mounted on the vehicle will be briefly described below. In the navigation device 21,
The current position data detected by the position detection device 22 is always converted to the origin point number O. In this state, when the user inputs the user number U, the service number S, and the landing point number D from the mobile telephone 1, the numbers U, S, D
Is given to the addition unit 25, the origin point number O is added by the addition unit 25, and the result is given to the automatic telephone communication device 21. Then, it is transmitted from the car phone communication device 20 to the central device 2 as a radio wave.

As described above, according to the traffic information providing system of the present embodiment, the current position data detected by the navigation device 21 is converted and obtained without manually inputting the origin point number O from the car telephone 1. Since the obtained point code number can be transmitted to the central device 2 as the departure point number O, the operation by the user can be simplified. Although the embodiments have been described above, the present invention is not limited to the above embodiments. For example, in the above embodiment, when the user transmits desired road traffic information to the central device 2,
Although the origin point number O and the destination point number D are manually input, this manual input may be omitted. In order to realize this, the following configuration may be used.

That is, for example, when the departure point is always the same point, the departure point number O representing that point is associated with the user number U, and the memory 7 provided in the central unit 2 is associated with the origin.
To remember. Therefore, the memory 7 also functions as the fourth storage means. The departure point may be, for example, "home". Further, a special service number Sa, which means that the type of road traffic information and the origin point number O are omitted, is added to the service number S. Further, the control unit 6 of the central apparatus 2 is provided with a function of identifying the contents of the special service number Sa and a function of confirming the origin point number O stored in the memory 7.

In this configuration, for example, when the user number U, the special service number Sa and the destination point number D are sent from the user, the origin point number O is omitted based on the special service number Sa sent. It is determined that For example, the special service number Sa and the landing point number D are sent in the format of "# Sa * D *". Then, the control unit 6 confirms the origin point number O corresponding to the user number U sent together, based on the correspondence between the user number U and the code number stored in the memory 7, and determines the road traffic information. , The point represented by the origin point number O and the point represented by the destination point number D are recognized.
After that, the same operation as in the above embodiment is performed.

According to the above configuration, when the origin is always the same and is the same location, the location code number representing the location is registered in the central unit 2 so that the origin number O can be input. It can be omitted. Therefore, the operation by the user can be simplified. In addition, although the said modification demonstrated the case where the origin point number O was registered into the central device 2, the destination point number D may be registered into the central device 2, for example. In this case, the landing point may be a “company” that commute daily. Further, if both the origin point number O and the destination point number D are registered in the central device 2, the user can enter the desired origin point and destination point by inputting only the user number U and the special service number Sa. Since it can be specified, the operation can be further simplified.

Further, in the above modification, for example, when there are a plurality of origin point numbers O or destination point numbers D to be registered, the control section 6 determines which number O or D is desired among the plurality. Not valid because it cannot be determined. Therefore, the origin point number O or the destination point number D you want to register is
When there are a plurality of items, the following configuration may be used.

That is, for example, the origin point number to be registered
When there are multiple O, each departure point number O _i(I = 1, ...
., N) and speed dial number i correspond to each other.
The user number U is associated with this and stored in the memory 7 and registered.
Make a note. Therefore, this memory 7 is the fifth storage means.
Also works as. The speed dial number i is
For example, a push button on the telephone such as "1" or "2"
It is a number in. Also, as in the above modification,
Type of road traffic information and origin number in the S number
O_iMeans to send as a speed dial number i
Add a special service number Sb to have. In addition, the above
As in the case of the example, the control unit 6 of the central unit 2 is provided with the above special service.
A function to determine the contents included in the service number Sb, and
And the origin point number O stored in the memory 7_iConfirm
Function to add.

In this structure, when transmitting the desired road traffic information, the user inputs the user number U, the special service number Sb, the speed dial number i and the destination number D. When each of these numbers U, Sb, i, D is sent, it is judged that the origin point number O _i has been sent as the speed dial number i based on the special service number Sb therein. Then, in the control unit 6, the origin point number O _i corresponding to the user number U and the speed dial number i sent together with the user number U and the speed dial number i stored in the memory 7 and the code number. Confirmed based on the correspondence, the type of road traffic information, the point corresponding to the origin point number O _i, and the point corresponding to the destination point number D are recognized. After that, the same operation as in the above embodiment is performed.

According to the above configuration, when there are a plurality of originating point numbers O _i to be registered, each originating point number O _i is associated with the speed dial number i and the user number U and the central unit 2 is operated.
By registering in the above, it is only necessary to input the speed dial number i when inputting the origin point number O _i . That is, as described in the above embodiment, the normal point code number has four digits and the speed dial number i has one digit.
The operation by the user can be simplified as compared with the above embodiment.
