JOB DESCRIPTIONS DEVELOPED IN AN EARLIER PHASE OF THE PROJECT WERE USED TO IDENTIFY TASKS HAVING THE GREATEST RELEVANCE AND UTILITY FOR EVALUATION. THE TASKS WERE ASSESSED IN TERMS OF THEIR IMPORTANCE TO GOOD TRAFFIC SERVICE PERFORMANCE AND TO HIGHWAY SAFETY, OBSERVABILITY, FACE VALIDITY FROM THE PERSPECTIVE OF THE TYPICAL PATROL OFFICER, AND UTILITY TO THE SUPERVISOR. THE FOLLOWING EVALUATIVE FACTORS WERE CHOSEN: PERFORMING PATROL; MAKING TRAFFIC VIOLATION STOPS; EVALUATING VIOLATIONS AND SELECTING ENFORCEMENT ACTIONS; ISSUING ENFORCEMENT ACTIONS; MANAGING AND INVESTIGATING TRAFFIC ACCIDENTS; PREPARING AND PRESENTING TRAFFIC-RELATED TESTIMONY AND EVIDENCE; PROVIDING HIGHWAY SERVICE AND ASSISTANCE; AND DIRECTING AND CONTROLLING TRAFFICE. THE FACTORS AND RELATED MEASURES WERE COMBINED IN A DRAFT EVALUATION SYSTEM, WHICH WAS THEN TESTED IN 10 AGENCIES REPRESENTATIVE OF STATE, HIGHWAY, AND LARGE AND SMALL MUNICIPAL DEPARTMENTS. IN GENERAL, THE PILOT TEST SHOWED THAT THE EVALUATION SYSTEM IS A VIABLE ONE AND CAN WORK UNDER A VARIETY OF OPERATIONAL CONDITIONS. DETAILS OF THE PILOT TEST AND ITS RESULTS AND COPIES OF ALL FORMS USED IN THE EVALUATION SYSTEM ARE PROVIDED. (LKM)
