Since the Congress authorized the categorical safety programs in the Highway Safety Act of 1973, the states have made much progress in their use of these special safety funds. Data are tabulated that show that in 1974 when the 55 m.p.h. speed limit was implemented, fatalities decreased 16% to 46,100. A figure illustrates the fatality rates between 1967 and 1976. Nonfatal injury rates have declined since 1967. The fatality rate and nonfatal injury accidents for highways off the federal aid system and the federal aid highways are compared. The relationships between severity of accidents and number of grade crossings for both on and off the Federal-aid system are tabulated. Analysis of the special safety improvement programs' accomplishments show that high-hazard location projects are cost effective. Over four-fifths of the high-hazard projects were either intersection or cross-section type improvements. Roadside obstacle projects showed the lowest percentage reduction for property damage only and total accidents. Fatal accident reductions were high. Since the purpose of the roadside obstacle projects is to provide a more forgiving roadside thus reducing the severity of accidents involving run-off road vehicles, the program's purpose is being achieved. The Rail Highway Grade Crossing Program showed the largest percentage reductions in accidents for all severities.
