Table Definition| Field | Type | Description |
|---|---|---|
| OBJECTID | Integer | A unique ID that indicates the object. |
| FROMLINKID | Integer | Road link ID of the first link in the link column. Corresponds to OBJECTID of the road link. |
| TOLINKID | Integer | Road link ID of the end link in the link column. Corresponds to OBJECTID of the road link. |
| MIDCOUNT | Integer | Number of links that are entered into the link between links corresponding to FROMLINKID and TOLINKID.0 when no link exists |
| MIDLINKID | Character |
2～N-1th road link ID column of the link column (N is the total number of links that consist of the link column). The ID column is described by delimited with a single-byte comma. Matches with the number of links indicated by MIDCOUNT. (One) Single-byte space is stored, when there is no link column. |

Examples of Link Column Regulation:
(1) Example of general link column regulation
|
Actually, set to the place of signboard of "CLOSED-TO-TRAFFIC EXCEPT SPECIFIED DIRECTION", not the place of signboard of "NO RIGHT/LEFT-HAND TURN". In the left figure, direct advance and left-hand turn are allowed. Therefore, the link column regulation of NO RIGHT-HAND TURN is stored as the red arrow head. |
(2) Example of special link column regulation
|
There is the case that the direction from A to C is not allowed, but the direction from B to C is allowed (Actually, the direction from A to C is considered as direct advance, and not allowed). In this case, if simply entering NO RIGHT-HAND TURN from E to C disables travel from B to C. Therefore, store the link column regulation as A⇒E⇒C. Then travel of B⇒E⇒C is enabled with no confliction. |
