This device, which collects information about vehicle and road conditions, conveying information about vehicle and road location to beacons, is mounted around a given road and includes information about road conditions including vehicle speed limit on the road. A radio transmitter 400 for transmitting information and receiving data transmitted about a road condition, mounted in a predetermined vehicle, receiving information on the road condition, transmitting the received information to the beacon 490, and information about the vehicle. It includes a vehicle terminal 450 for transmitting to the beacon 490.

The wireless transmitter 400 receives data on a road condition, and transmits input data when a channel for transmission is empty, and a memory unit 410 storing data to be transmitted on a road condition. If there is data stored in the pager receiver 415 and the pager receiver 415 for temporarily storing the data received through the wireless module 405, the data stored in the memory unit 410 is modified according to the data. A central processing unit 420 is stored in the 410, and reads the data stored in the memory unit 410 at a predetermined period and transmitted through the wireless module 405.

The wireless transmitter 400 receives a commercially available 110/220 volts or is supplied with a solar cell to supply a current of 5 volts (or may have a different value of voltage) used by the wireless transmitter 400. A power supply 425 is included. The power supply 425 may be powered from the battery in case of power failure or night.

The vehicle terminal 450 is supplied with a power of 12/24 volts generated from the vehicle and supplies a current of 5 volts (or may have a different value of voltage) used by the vehicle terminal 450. ) Is included.

Hereinafter, the operation of the embodiment of the present invention will be described in detail with reference to the above configuration and method.

The wireless transmitter 400 or the vehicle terminal 450 should be mounted at a specific place for collecting information.

Wireless transmitter 400 should be installed in the building of the main intersection to locate the main trunk road. Or it could be attached to a facility such as a streetlight or a pole. The wireless transmitter 400 may store in advance a coordinate value indicating a position where the wireless transmitter is located in the memory unit 415. The radio transmitter 400 may transmit this coordinate value. Of course, the coordinate values may be wirelessly received and stored in the memory unit 410. If there is a vehicle speed limit value of the road where the radio transmitter is located, the limit value may be stored in the memory unit 410.

The vehicle terminal 450 is mounted to a vehicle traveling on a main trunk road. The vehicle equipped with the vehicle terminal 450 receives the data transmitted by the wireless transmitter 400 while passing through the place where the wireless transmitter 400 is located, and records the data reception history in the memory unit 460. When the vehicle equipped with the vehicle terminal passes through the place where the beacon 490 is located, the signal for distinguishing the reception history from the vehicle is transmitted to the beacon 490 and the history is deleted. A signal capable of distinguishing a vehicle may be implemented by transmitting a value such as a predefined vehicle identification number. At this time, information about the vehicle, that is, a value such as the speed of the vehicle may be transmitted together.

At this time, since the transmission from the wireless transmitter 400 to the beacon 490 through the vehicle terminal 450 is performed at a short distance, it may be possible to use short-range small power equipment. For this purpose, a device using a dedicated short range communication (DSRC) can be used.

The beacon 490 transmits the raw data through the vehicle terminal 450 to the traffic analyzer 160 having an analysis function.

In order to display real-time traffic information, the number and mutual table for the representation of geographic information is designed and the result is stored in the information storage unit 150. To this end, traffic data, intersection data, and road data can be added based on the domestic industry classification.

The branch system follows the statutory dong system and can be composed of the provinces, cities, counties, dongs, villages, towns, streets, and houses. This is a table to be used for traffic information retrieval using addresses, and in order to improve the efficiency of address retrieval, a east table and a state / province / county table may be added.

In addition, for ease of road search, a database including fields such as address, phone number, and homepage corresponding to each other may be constructed based on the name of each other.

For traffic information, a database of traffic information to be displayed in connection with map information may be designed. Intersection data database can be constructed with the number of each road, each node data of the road, and can be linked and serviced by a layer on the map. For the name of the road, you can write a well-known street name. Coordinates may also be set for each node to determine the location of the vehicle.

The real-time traffic information service device connects the conventional geographic information service and the traffic information service collected according to the present invention, and improves readability by displaying traffic information on a map so that users can acquire information more easily. There is an advantage.

For this purpose, in order to express traffic information more easily, the average driving speed of each road is displayed in three different colors so that the driving speed can be recognized at a time. In addition, an arrow-shaped icon is used to display the speed of each road, thereby preventing the ambiguity of grasping the direction of travel of the vehicle at the shortest distance.

At this time, it should be noted that displaying traffic information for all intersections displayed on the map does not cause technical problems, but it takes too much load when the traffic analysis unit 160 exchanges information to obtain traffic information. It only expresses traffic information centered on the nearest intersection from the displayed center coordinates.

In order to easily express and recognize traffic information, the following points can be set.

1. Different roads by speed are displayed on the map in different colors.

2. Use the arrow icons to distinguish between the up and down lanes.

3. Each intersection name is displayed in layers on the map.

4. Construct a traffic-oriented layer on the map.

5. In the case of traffic information service, each intersection name or waypoint name is expressed in a list at the bottom of the screen and the correct driving speed is output.

6. When searching for the shortest route, the service shall be considered in consideration of three kinds of general search, exclusive road search and driving speed search. The shortest path search will be described later.

7. In some specific areas, traffic information is provided without using a map.

To implement each step of FIG. 3, the following implementation method may be used.

The traffic analysis unit 160 may process all the data to be output through the user terminal and transmit the data to the user terminal, or transmit the data before processing to the user terminal and the user terminal receives the data received by the prepared program in advance. You can also process the output and output it for your viewing. The sharing of this functionality may vary from designer to designer and from implementation to implementation. Therefore, this description will not describe separately where each function is implemented in the traffic analysis unit or the user terminal.

In operation 300, the programmatic function of transmitting necessary data for each service type requested by the user to the traffic analysis unit 160 generates a header of a predefined packet according to the service requested by the user. The traffic analysis unit 160 analyzes the header in step 320 to identify the service type, provides a service according to the corresponding type, and generates a packet according to the corresponding type and transmits it to the user terminal.

A function that extracts traffic information for each node by analyzing the transmitted packet in the web service program of the user terminal analyzes the header of the transmitted packet and extracts speed information and node name for each road node.

The function for transmitting data to the map generation program sends the data to the map generation program using a list including node ID and vehicle speed information. In order to transmit, use the Form function on the Web.

The function that outputs a detailed list at the bottom of the screen outputs traffic information such as speed data more detailed than the data displayed on the map as a list at the bottom of the screen of the user terminal on which the map is displayed, and links each intersection so that the user can use the service more conveniently. You can do it. When printing the list, display the names of both nodes, and output the speed information between nodes in the same color as the color of the map.

The main function that creates the base map screen in the program for map output function creates the base map using the base base map of the map to be expressed based on the transmitted center coordinates, and reads and adds the layer to be displayed on the base map. Create a final map.

A function that outputs the name of each intersection on the base map retrieves the name of the intersection in the range and outputs the opposite in order to express the names of the intersections in the range to be displayed on the map. Also for readability.

A function that retrieves the intersection nodes associated with the transmitted intersection number retrieves the intersection with the transmitted intersection and links and expresses the speed data for each link.

Function to read and express the layers to be printed on the map The layers to be displayed on the map are classified by level and expressed on the map. In addition, when multiple attribute information is located in a region, each attribute overlaps to reduce readability. In order to exclude this, it is necessary to rearrange each attribute information. Therefore, it would be desirable to include a function to modify the presentation position of the attribute information so that it does not overlap at least.

Internet map retrieval system that enables to search geographic information and traffic information about a desired place for driving a vehicle can be classified into two categories according to the search method. The first method is to search by business name and the second method is to search for a desired place by intersection name.

The function of searching for a desired place by intersection name can be executed as follows. 5 shows a screen for searching for a desired place by intersection name. When searching for intersections, searching for most intersection names in the database of the current information storage unit 150 and collecting and constructing other names of commonly known intersections can be prepared so that users can search without knowing the intersection name exactly. There will be. In addition, when there is no result, only two letters before the intersection name can be changed to a search word and the maximum result can be output.

Search for the intersection name and print it out as a list if there is more than one result. Connect to the information storage unit 150 with the intersection name selected by the user, search for the ID and the road number of the intersection, transmit it by including it in the packet to be transmitted as traffic information, and search the central coordinate among the information on the intersection to search the user's web. It is expressed through the browser (step 330). The results are shown in FIG.

You can use the center of the map, zoom in and zoom out on the screen of the searched results, and search results for other intersections can be searched directly without going through a separate search process. do.

Another way to get traffic information for a desired place is to search by facility name. First, enter the name of the facility information you want to search and click the search button, the screen shown in Figure 7 is output.

If the entered word is 'Korea', all mutual data starting with the entered business name are displayed and shown to the user. The user clicks a desired place in the list and sees the searched result as shown in FIG.

In the facility data search result screen, the center of the map can be moved, enlarged and reduced, and it is more convenient to be able to immediately search for intersection information when the mouse is clicked.

The optimal route search function informs the optimal distance by referring to the current traffic information and road information from the departure point to the arrival point and guides the fastest route at the current time. In addition, information on distance and speed for each section may be provided.

As shown in FIG. 9, when the address or the trade name of the starting point and the intersection name are input and the address or the trade name and the name of the intersection are entered and the search button is pressed, the fastest route is obtained from the current time to the starting point and the destination.

10 shows a search result screen. In the result screen, the direction of movement is illustrated by the arrow icon to display the optimum route from the starting point to the destination, the speed information for each section, and the direction of travel. It may be desirable to implement a route search easily through a hyperlink for each waypoint for the name and easy search for each waypoint.

To find the optimal path, the basic algorithm may use the shortest path algorithm, which may be implemented as shown in the following table.

void ShortestPath (const int n, const int v) {for (int I = 0; I <n; I ++) {s [I] = FALSE; dist [I] = length [v] [i];} s [v ] = TRUE; dist [v] = 0; for (int I = 0; I <n-2; I ++) {int u = choose (n); s [u] = TRUE; for (int w = 0; w <n; w ++) {if (! s [w]) if (dist [u] + length [u] [w] <dist [w]) dist [w] = dist [u] + length [u] [w ];}}}

Describe the functions for collecting traffic information.

The wireless modules 400 and 450 respectively included in the wireless transmitter 400 and the vehicle terminal 450 use an asynchronous and half-duplex method by frequency shift keying, and a transmission speed of 4,800bps can be used. have. The output of the wireless module is less than 10mW, which can be adjusted according to the road shape and the length of the danger zone. The communication range of the wireless module can be varied from 50 to 700m by adjusting the output on roads without obstacles.

The wireless module is used for vehicle transmitters and roadside transmitters, so it can operate accurately even at very high temperatures, low temperatures (-20 to 70 ° C), high humidity, vehicle vibrations, and engine noise such as ignition devices. Needs to be. An example of the requirements for this radio module is set as shown in the following table.

Step 2: Transfer the read data to the wireless module 405.

Step 3: The wireless module 405 checks whether the corresponding channel is empty and launches the data wirelessly.

Step 4: After the data is released from the wireless module 405 notifies the central processing unit 420.

Step 5: Check if there is data received by the pager receiver 415.

Step 6: If there is data received, search for data errors, interpret the meaning and correct the data to be sent.

Step 7: Repeat Step 1 through Step 6.

Step 4: Calculate the speed limit at the current position.

Step 5: Measure the current traveling speed from the tachometer (480).

Step 6: Evaluate if you are out of the speed limit range.

Step 7: When the speed is out of the range, the voice is guided through the voice output unit 470. The display unit 475 displays the danger content, the speed limit, and the current speed.

Step 8: When the beacon 490 is met, the radio transmitter reception history stored in the memory unit 460 is transmitted to the beacon 490 together with the vehicle number or the vehicle identification number and then the history is deleted.
