Abstract:This project will provide the Texas Department of Transportation (TxDOT)with information about the effects of the current cost-effectiveness criterion. The project has reviewed (1)the cost-effectiveness criteria used by other states, (2)the noise barrier construction history of the other states,and (3)the effect the cost-effectiveness criteria has had on noise barrier construction. The esearchers examined the effect of the Texas cost-effectiveness criterion on decisions regarding noise barrier construction during recent years. Typical residential scenarios where highway noise impacts residences were also evaluated to determine when the cost-effectiveness criterion would indicate the need for constructing a noise barrier. Recommendations are made concerning the optimum monetary level for that criterion.
