The operation is described, the findings are summarized, and effective procedural aspects are isolated of the first year of the Evanston enforcement program. During this year, the number of accidents decreased 20 percent from the previous year along the four streets selected for concentrated patrol. The number of accidents resulting in death or injury decreased 12% along the four streets, while those along other streets increased 21%. The only apparent change in the driving environment during the first year of the project was the increased police traffic patrol and enforcement of traffic laws at the selected sites. The measures used by the police department in setting objectives for the project are explained. The measures include: percentage change per month; arrest index; and conviction rate. In the evaluation of the project two additional measures were used: severity per rate (the number of fatal or injury accidents per 1000 accidents) and the number of contacts per hour (total number of citations and warnings issued per man-hours of patrol). Details of the results (the effect on accidents, the effects on citations, increased patrol, arrest and enforcement indices and the public information program) are given.
