Departmental Papers (ESE)

Pedestrians, private automobile, public transpor­tation and other modes are components of a total urban transportation system. However, for historical reasons and because of major differences in their physical, operational and cost characteristics, different modes are being planned and operated by different organizations or public agencies.

Heavy Obstacles For Light Rail, Vukan R. Vuchic

Departmental Papers (ESE)

Close to 500 persons, including government officials, transit system operators, city planners, car builders, suppliers, and consultants, came to Boston Aug. 28-31 for a "National Conference on Light Rail Transit." Although the size of the crowd was evidence of light rail's growing popularity (RA, Aug. 8, p. 36), the conference also heard warnings about trends that could hamper the growth of light rail. Vukan R. Vuchic, pro­fessor of transportation engineering at the University of Pennsylvania, discussed some of those disturbing trends in a speech delivered at the meeting. Following are excerpts of his remarks.

Dickey-Lincoln School Lakes Project Environmental Impact Statement: Appendix H: Noise Impact Assessment, Stone & Webster Engineering Corporation, New England Division, United States Army Engineer Division

Dickey-Lincoln School Lakes Project

The overall project area can be described as a very quiet natural area remote from any major industrial activity, but subject to high traffic noise levels along the main road. Noise sensitive areas consist of low density residential areas in the villages and widely spaced residences along the main road. The estimated yearly average Ldn for all noise sensitive areas 1s 60 dB due to the close proximity of traffic to all residences. The yearly average Ldn decreases to 40 dB at 600 ft from the main road, and to 30 dB 1n the timberland areas.
