4.3 Development of Road Facilities Information System
A facilities information system was developed to maximize
visual effect on the facilities installed on a road. In the data
input of the facilities information system developed in the study
as in Fig. 17, OPEN button pops up a dialog box to select a
data in DB. View is composed of 4 sections; top left, bottom
left, top right, and bottom right.
Top left views the real local photo of the data in DB, and top
right views. the digital topography of the target area. Bottom
left expresses the scattering of data onto grid in which each
point records and saves the attributes of facilities on it. Bottom
right views the close-up of a point on the photo in top left when
clicked with mouse. Addition of the study is that road manager
takes the motion picture of the present status of the road and
makes it available so that users can grasp the present status of
the road. Also, road managers take the road pictures over time
and save them as motion picture. This motion picture module is
in Fig. 18.

5. Conclusion
A more exact and economical road information system was
developed using digital photogrammetry. The conclusions are
as follows.
First, to obtain road information using digital photogrammetry,
a road was shoot in the 4 corners in each zone along road
extension and proceeded to bundle adjustment. RMSE was
4—7cm, indicating that it was within the allowable error of
reduced scale of 1:12,000.
Second, in digital photogrammetry, it was possible to obtain 3-
d coordinates of road center line and facilities through
orientation with natural points, when the error was 2—-5cm, a
practical range. It was thought that control score could be much
