CAUSES AND COSTS OF HIGHWAY-SIGN REPLACEMENT

THE CAUSES OF SIGN REPLACEMENT INCLUDE NATURAL DETERIORATION, VANDALISM, DAMAGE BY VEHICLES, AND CHANGES IN LAWS OR POLICIES WHICH MAKE SIGN MESSAGES OBSOLETE. OPINIONS DIFFER GREATLY AS TO THE RELATIONSHIPS OF THE VARIOUS CAUSES OF REPLACEMENT, THE AVERAGE LIFE OF SIGNS, AND THE RELATIVE IMPORTANCE OF CERTAIN FACTORS IN LOCATION AND ENVIRONMENT. IN ORDER TO SECURE RELIABLE INFORMATION ON EXISTING CONDITIONS, DATA WAS OBTAINED FROM A REPRESENTATIVE SAMPLE OF SIGNS REPLACED DURING A PERIOD OF ONE YEAR. USING A QUESTIONNAIRE FORM, FOREMEN OF SIGN REPLACEMENT CREWS RECORDED ITEMS OF INFORMATION ABOUT EACH REPLACED SIGN. THESE ITEMS INCLUDED DETAILED INFORMATION REGARDING AGE, LOCATION, AND REASONS FOR REPLACEMENT. THE MASS OF DATA WAS HANDLED BY PUNCH CARD MACHINE METHODS AND THE ANALYSIS WAS COMPLETED WITH THE AID OF ACCEPTED STATISTICAL PROCEDURES. THE PAPER INCLUDES A SUMMARY OF THE MORE INTERESTING AND SIGNIFICANT FINDINGS, AND MAKES INTERPRETATIONS OF THEIR MEANINGS TO SIGNING PROBLEMS. /AUTHOR/
