This appendix presents a series of accident distribution plots for camp segmens, ramps, speed-change lanes, and combinations thereof. These include:

• Ramp proper segments, off-ramps only (rear-end accidents exluded from frequency distributions) in figure 9.
• Speed-change lanes (total and fatal and injury multiple-vehicle accidents) in figure 11.
• Entire ramps, off-ramps only (rear-end accidnets excluded from frequency distributions) figure 10.
• Entire ramps plus adjacent speed-change lane (total and fatal and injury multiple-vehicle accidents) in figure 12.
• Urban diamond off-ramps (total and fatal and injury multiple-vehicle accidents) in figure 13.
• Urban parclo and free-flow loops off-ramps (total and fatal and injury multiple-vehicle accidents) in figure 14.
• Urban outer connection off-ramps (total and fatal and injury multiple-vehicle accidents) in figure 15.

In addition, 1-year accident (total and fatal and injury multiple-vehicle accidents) for the 551 entire ramps and the 737 ramp proper segments studied in this report are presented in figures 16 and 17, respectively, comparing the 3 years of accident data for 1993 through 1995.
