by hand measurements, as shown in Figure 19. The remain-
ing site characteristics were collected from the video.
Finally, observers also took multiple pictures of each site
using a digital camera. These pictures illustrated the various
approaches to each crosswalk, relevant traffic control devices,
other conditions at the site, and any unusual characteristics
that might have been present. The pictures supplemented the
sketch and the recorded video for use in reviewing character-
istics of each site.
Data Reduction
Both video and palmtop computer data were post-
processed manually to determine pedestrian behavior at each
site. PDA data were downloaded and stored in a database file
at the conclusion of the study period for each site. These data-
base files were converted to spreadsheet files to expedite cal-
culations for various emphases in the data reduction: motorist Figure 19. Measuring dimensions at a study site.
