A nationwide systematic approach to assess the developments and achievements of highway safety activities was conducted to measure program outputs from 1969 through 1974 using key indicators of performance such as ratios and percentages. A sample of 10 states was selected with overall sample of 105 local jurisdictions which would provide estimated national highway safety trends. Several criteria were used as the analytic base for the interpretation of national results: trends in program performance (resources, activities, and outputs) matched against growth in numbers of licensed drivers, vehicles, road milage, and miles of highway travel; program productivity in terms of outputs per unit or manpower time; trends in unit cost; and direct and indirect effects of state and community grants. Summaries of findings are given for the following program areas selected for study: (1) the funding of highway safety programs, (2) police traffic services and adjudication, (3) drinking-driver countermeasures, (4) emergency medical services, (5) driver education, (6) driver licensing, and (7) periodic motor vehicle inspection. Making up the bulk of the document (99 pages), key statistics and an extensive statistical analysis are presented for each of the program areas. A list of state and local contacts is included.
