The paper presents both qualitative and quantitative data on the relationship of emerging Personal Rapid Transit systems and the environment. Specific reference is made to comparison of these systems with the U.S. air pollutant inventory and with the automobile. Thermal pollution and reduction of power supply requirements for these transit systems are considered. Definitive specification information for interior/exterior noise levels, in comparison with other transportation modes and with background conditions, are provided. Visual aesthetics of guideway, station, and vehicle design are presented as the most challenging remaining problem in the integration of Personal Rapid Transit systems into the society.
