Abstract This report describes the noise climate on and near the Port Authority Transit Corporation (PATCO) Lindenwold High Speed Line. It is one of a series of coordinated assessments sponsored by the Urban Mass Transportation Administration and technically administered through the Transportation Systems Center of the U. ^Depart- ment of Transportation. The PATCO urban rail transC approximately 14.2 miles of two-way revenue track four miles are in subway), and 12 stations. Noise is given for specific measurements made in cars, ir and along the non-subway wayside at appropriate loc Based on these measurements, in-car average maximun sound levels, LA (Max), range from 72 to 84 dBA and to be in the 70 to 79 dBA interval for 95 percent route. Wayside La (Max) levels, at 15m (50 ft) frd track, range from 76 to 84 dBA and are in the 80 t4 interval for 84 percent of the above ground route tion La (Max) levels are somewhat more dispersed, a* 70 to 74 dBA interval for 42 percent of PATCO stations, and in' the 80 to 89 dBA interval for 58 percent of the stations. The rationale for choice of measurement sites and the methodology for arriving at the summary noise distributions from the data are discussed explicitly. Measurement and analysis instru- mentation and procedures are also described. 17, Key Words 18, Distribution Statement Noise, Rapid Transit, Transportation Noise, Measurement Methodology, In- DOCUMENT IS AVAILABLE TO THE U.S. PUBLIC THROUGH THE NATIONAL TECHNICAL strumentation, Data Analysis, Comunity INFORMATION SERVICE, SPRINGFIELD, Noise, Station Platform Noise, Vehicle VIRGINIA 22161 Noise 19.

PREFACE This report has been prepared under the Urban Rail Noise Abatement Program being sponsored by the Urban Mass Transportation Administra- tion's (UMTA's) Office of Rail and Construction Technology. The Noise Abatement Program is being managed at the Transportation Systems Center for UMTA. The objectives of the Noise Abatement Program are to assess noise produced by urban rail transit opera- tions and to appraise methods and costs for reduction of such noise. This report is one in a series of six noise assessment reports covering noise due to transit operations on seven rail transit systems in five U.S. cities. Consistent results of the six assess- ments were achieved through use of standardized noise measurement and data reduction procedures developed at TSC and tested on the Massachusetts Bay Transportation Authority (MBTA) in Boston. The assessment report for the MBTA was published in 1974 (Reference 1) Physical differences among the transit systems, as well as differences in the technical orientations of the teams, and in funds available to the teams for measurement and analysis, led to some differences in report organization, technical depth and writing style. Therefore, to provide at least introductory con- sistency among the reports for the reader, the front material, including the introduction of each assessment report, has been edited at TSC. The organization and technical content of each report, however, are basically as originally written by the res- pective teams and are, together with the accuracy of the measure- ments, the responsibility of the authors. This report has been prepared by the Boeing Vertol Company under contract DOT-TSC-850. Authors of the report were R. H. Spencer and E. G. Hinterkeuser . Technical Monitors for the program were Dr. E. G. Apgar and Dr. Robert Lotz Liaison with the Port Authority Transit Corporation was provided by Mr. David L. Andrus. Dr. Leonard Kurzweil of the Transportation Systems Center directed the final technical editing of the report. fi in FACTORS CONVERSION METRIC IV TABLE OF CONTENTS PAGE LIST OF FIGURES Vll LIST OF TABLES xii LIST OF DEFINITIONS xiii 1-1 1 .
