This report is the result of a one year study of road side accidents in the state of Illinois. The study was conducted by the Department of Criminal Justice Sciences at Illinois State University. The purpose of the study was to review and analyze road side accident data from the Illinois Department of Transportation and to review literature applicable to accidents of this type. Some of the findings are as follows: (1) Road side accidents were least frequent from 6 a.m. to 7 a.m. and increased steadily until the hourly intervals of 3 p.m. and 4 p.m.; (2) Road side accidents were lowest from Monday through Thursday; (3) Smaller communities were least likely to have accidents, while the likelihood of accidents increased with community size; (4) Non-marked roads accounted for 97% of all accidents in Illinois involving vehicles parked legally on the side of the road; (5) 75% of all road side accidents occurred under dry driving conditions; (6) Road side accidents were infrequently associated with road deficiencies; (7) 3 types of vehicles were much more likely to be the vehicle causing the accident than the vehicle struck - single-unit trucks, vans, and pickups; (8) Of 4 emergency vehicles used in the study, police vehicles were the most likely to be struck and the most likely to strike another vehicle; (9) Injuries were more prevalent among drivers of vehicles causing the accident than among drivers of the vehicle struck; (10) Alcohol was not an important contributor to road side accidents; (11) The most frequent maneuver of the striking vehicle prior to the accident was driving straight forward; (12) Police road side accidents at night were proportionally similar to passenger car accidents; (13) Injuries from road side accidents involving police vehicles occurred nearly three times as often as injuries for passenger vehicles, and half again as often for other emergency vehicles; (14) The normative condition for road side accidents appears to be when the weather is good, the roads are clear, drivers are not impaired, and drivers of striking vehicles are driving on a straight section of roadway.
