Because there is no standardized method for prioritizing highway noise-barrier retrofit projects, states that have such programs have had to develop their own. The methods of four states that have established ongoing noise-barrier retrofit programs--Minnesota, Maryland, Connecticut, and California--are examined. A comprehensive method developed by the New York State Department of Transportation (NYSDOT) is analyzed in detail. The seven-phase New York procedure relies heavily on field reconnaissance. A preliminary listing of potential projects is developed by computer analysis early in the process, and this listing is then refined several times as new information is gathered. The final outcome of the method is a list by NYSDOT region that shows potential projects by L sub 10 "zone" (zone 1 for L sub 10 values greater than 80 dB(A), zone 2 for values of 75-80- dB(A), and zone 3 for values of 70-75 dB(A)) and indicates a cost/benefit surrogate per project site. The cost/benefit surrogate selected is square meters of barrier required versus number of receptor units protected. (AUTHOR)
