RIDE QUALITY AND GUIDEWAY ROUGHNESS MEASUREMENTS OF THE TRANSPO '72 PRT SYSTEMS

An extensive series of performance and evaluation tests has been conducted on the four Personal Rapid Transit (PRT) systems demonstrated at the Dulles TRANSPO '72 transportation exposition. Included among these tests were the measurement of vehicle ride quality and of guideway irregularity. In the Ride Quality tests, a portable instrumentation system developed at the applied Physics Laboratory, the John Hopkins University, was used to measure the accelerations experienced by passengers aboard the four PRT systems while operating over a wide speed range and during various modes of operation. Volunteer subjects rode the systems and these ride juries provided ratings on ride quality, appearance, safety, and convenience. Guideway Roughness and Alignment tests were conducted to determine the characteristics of the vertical and horizontal running surfaces. These tests are briefly reviewed and a sample of the results is presented. The ride quality tests show that meaningful vehicle accelerations can be measured and that the data can be successfully processed for correlation with ride quality specifications and subjective judgments. It is shown that accelerations on the seat can be greater than those on the floor and that in some instances measured jerk values were higher than those considered to be acceptable.
