- a description will be given of a method of increasing the height.
- Fig. 14 schematically shows the contents of the processing in this position information transmission method on a map.
- the transmitting node is selected from the nodes of the target road section as shown in FIG. 14 (2).
- a group of nodes is selected so that the receiving side can identify the difference from the shape of the adjacent road at the location where the matching is poor due to the existence of adjacent roads running side by side. .

- the position of each node on the map on the receiving side of each node is calculated by map matching.
- the position of each node on the receiving map can be accurately determined. Can be sought.
- the shortest paths between the intermittently located nodes are searched sequentially, and the obtained shortest paths are connected in order to reproduce the target road section. .
- the transmitting side selects nodes to be included in the node group based on the following criteria, for example.
- the judgment value is
- the node Pj is a node that is poorly matched on the receiving side.
- nodes that precede and follow node Pj are judged to be nodes with incorrect matching based on the criteria in (1), and erroneous matching occurs on the receiving side. Until a difficult node is found, the nodes to be judged are sequentially expanded. If a node with ⁇ 0 that is less likely to cause erroneous matching on the receiving side is found, it is assumed that a shape that can discriminate the difference from the adjacent road shape has been obtained, and that node and ⁇ j ⁇ . Each node determined as is adopted as a node group.
- FIG. 17 shows an example of a procedure for selecting nodes to be included in the node group.

- the transmitting side evaluates the possibility of erroneous matching on the receiving side, and the receiving side increases the number of transmitting nodes at the erroneously matched dark road.
- the matching accuracy of the target road section is improved, and the target road section can be faithfully reproduced.
- the method of evaluating the possibility of erroneous matching on the receiving side based on the distance to the adjacent road and the difference in the intercept direction described above is based on the shape beta data sequence described in the “Conventional Technology” section. It is also possible to apply to the method of transmitting “road shape data”. Depending on the evaluation value, the length of the road shape specified by the shape vector data sequence and the nodes included in the shape vector data sequence The number can be determined.
- the receiving side obtains the shortest route between the nodes by a route search and reproduces the target road section. Roads that are not included cannot be reproduced. For example, if the version of the digital data map on the receiving side is old and does not include data on the recently opened road, it is impossible to connect intermittent nodes specified by the transmitting side with this open road. is there. As a result, there is a discrepancy between the target road section intended by the transmitting side and the target road section reproduced by the receiving side, and the receiving side incorrectly interprets the event as occurring on another road. Occurs. Such a situation often occurs when the transmitting side is actually an information providing means of the traffic information providing system and the receiving side is a car navigation device which receives provision of the traffic information.
- the transmitting side identifies the set date of the target road in the digital map data, and selects the type of position information transmission method to be used according to the set date.
- Setting 3 in the digital map database of roads almost coincides with the opening time of the road. For example, if the target road is a road that has not yet been opened, the ratio of car navigation devices that have a digital map database that includes data on this opened road is extremely low! /, Is seen.
- the transmitting side may transmit the data on roads other than the target road (even if it is impossible to identify the target road). Advertise the traffic information by using a location information transmission method that will not cause a misunderstanding that an event has occurred.
- the data set date of a road is defined for each road link in the digital map database, use that date. If the set date is not defined, each version of the digital map data is compared, and the set date is calculated from the revision time of the purge line where the road link was first registered.
- the transmitting side transmits the shape vector data string information including the information indicating the set date of the data of the target road and the information of the distance between the nodes.
- the receiving side refers to the data setting date of the target road in the received shape vector data string information, and if it determines that the data of the target road is not included in its digital map database, the target road section Stop reproduction of.
- the data of the target road is Judge that it is not included in the digital map database and stop reproducing the target road section.
- the flowchart of FIG. 18 shows the processing procedure on the transmitting side.
- Step 30 Select the target road section
- Step 31 Select a node to send.
- Step 32 If the data setting date of the road between the selected nodes is the same as the reference date (prescribed value) or older than the reference date,
- Step 33 Adopt the position information transmission method of the first to third embodiments.
- step 32 if the data setting date of the road between the selected nodes is newer than the base date,
- Step 35 Adopt a position information transmission method that transmits data that directly represents the road shape of the target road section (such as a coordinate data string of each node that specifies the road shape).
- Step 36 Send location information based on the method adopted.
- FIG. 20 illustrates shape vector data string information transmitted by the method of the present invention.
- This information includes the data setting statement and the search distance data between the nodes.
- the flowchart in FIG. 19 shows the processing procedure on the receiving side that has received this shape vector data string information.
- Step 40 Receive information
- Step 41 Referring to the additional information, determine the coordinates of each node by map matching.
- Step 42 Identify whether the data setting date between each node included in the received data is older than the creation date of the map data of its own device.
- Step 43 Perform route search between nodes with reference to additional information, and determine target road section.
- Step 44 Identify whether or not the difference between the determined distance of the target road section and the search distance between nodes included in the received data is within a specified error.
- Step 45 Reproduce the overall shape of the target road section.
- step 42 if the data setting date is not older than the creation date of the map data of the own device, or in step 44, the difference between the distance of the target road section and the search distance between nodes included in the received data is calculated. If it is not within the specified error, discard the information between the nodes.
- the shape vector data string information may include only one of the forces indicating the case where both the data setting date of the road between the nodes and the data of the search distance are included.
- the digital map position information transmission method of the present invention and the apparatus for implementing the method can efficiently and accurately transmit the information on the shape and position of the digital map with a small amount of data. Can be transmitted, and data transmission efficiency can be improved.
