Abstract
In this research, the plane view for road management which authors developed in the past was made into the portal site, and improvement in functional of the prototype system which a figure, position information, attribute information, and incidental information linked per route was aimed at. Specifically, the alignment information on a completion road was restored from the alignment figure, it is giving a definition strictly as public coordinates, the gap of the position as road property was lost, and long-term asset-management was attained. Moreover, the survey examination by reference by GPS is alsoperforming the method of restoring coordinates from an alignment figure. Furthermore, the accident protocol was database-ized by XML and accident analysis, and reference and extraction were attained by making it link with a plane view as an attribute. And matching with an adjoining self-governing body's management figure can be taken now by having enabled it to also define the point of contact of a management classification figure or a drainage figure.
