Abstract

This thesis is about traffic noise control policy. The purpose of this policy is to mitigate the conflict between the competing public demands for transportation infrastructure and for preserving environmental quality. The main approaches for mitigation of this conflict are: (1) the technical approach that determines a specific standard and enforce compliance and (2) the economic approach that determines the acoustic protection based on the optimization of benefits and costs.

The objective of this research project is to develop a model for identifying the optimal protection from traffic noise impacts. This model will assist in the analysis of the impact of the protection alternatives and in the estimation of the benefit in residential areas. This model is based on an earlier work that presented by Krell K. in Germany in the late 1980’s. The model considers both the level of noise exceedance and the number of people affected by this exceedance. Adapting this model for use in Israel required adjusting the model parameters and inputs. Most significantly, this adjustment required calibrating in Israeli currency (NIS (the economic utility (K) of a reduction of one decibel (1 dBA) of noise for a person or a residence.

The enhanced model enables the identification of the optimal combination of measures that maximize acoustic mitigation benefits while minimizing construction costs. The model may also be used to assess the optimal criteria noise level in terms of its impact intensity on surrounding populations.
