Abstract:

The New York Program for restoration, rehabilitation and resurfacing (3R's) has relied on broad scoped projects and case-by-case consideration of exceptions to design standards (separate 3R standards have not been approved). This program has resulted in enhanced highway safety demonstrated by a 21 per cent reduction in total accidents on 79 projects evaluated. Injury accidents showed a 9 per cent reduction. These conclusions and other specific areas of accident reduction, such as 33 per cent reduction in wet weather accidents, are substantiated by a 'before' and 'after' accident analysis of non-freeway, predominantly rural, two-lane highway improvement projects completed in New York with the 3R Program over a 4 one-half year period between September 1977 and February 1982. The 79 projects reflect a substantial statistical sample of the estimated 400 to 600 similar projects undertaken during this period. The programwide accident reduction compares favorably with reductions experienced from safety category programs such as Hazard Elimination.
