TRAFFIC NOISE NEAR HIGHWAYS

The report discusses parameters used to measure and describe noise. It presents and discusses a noise emission model for automobiles and a free field noise dispersion model for predicting equivalent noise level. Noise barriers are discussed at length. A formal nomograph method is presented for predicting barrier effectiveness against truck noise peaks. A computer method is also given for predicting barrier effectiveness. There are ancillary notes on noise reflections, ground effects and atmospheric effects. arts in transportation. To accomplish these objectives, NEMC created a 15-member New England Task Force on Transportation Design and the Arts. To insure full representation of those involved in transportation planning and decision-making, the Task Force membership included government officials, transportation planners, transit operators, and regional planning agency staff. Private sector art directors were also represented. The Task Force served as a resource to identify the perceived needs of local governments vis-a-vis aesthetics in transportation and the opportunities and constraints associated with such efforts. To document the perceptions, ideas and considerations of the Task Force members and to further analyze local situations, NEMC conducted ten site visits in locations throughout New England. The sites represented a cross-section of New England, including at least one community in each New England state and two regional planning agencies (RPAs). The RPAs were included to provide a regional perspective from areas where a regional approach to transportation planning and services is being used. NEMC's research methodology emphasized comparative analysis. By selecting four communities with successful, aesthetically designed transportation systems and comparing them to four communities that were restricted in their efforts to include aesthetics, NEMC was able to identify reasons for successful programs and constraints to programs in other communities. Individuals interviewed during the site visits included transit operators, planners, town managers and community development directors. They provided first-hand information on how their transportation systems operated and the impact of aesthetic design on their projects. The information included in this report is based on the site visits and Task Force meeting discussions, and covers the following: constraints at the local level precluding design consideration; current or planned activities at the local level to consider design in transportation in five New England communities; future transportation project possibilities for design in four communities; and recommended actions to promote design in transportation systems at the local level.
