The purpose of this part of ANSI S2.72 / ISO 2631 is to help in the design and evaluation of fixedguideway
passenger systems, with regard to the impact of vibration and repetitive motions on
passenger comfort. Fixed-guideway vehicles provide a predictable but complex multi-axis motion
environment that is a function of the guideway, vehicle and seat or berth. Passengers evaluate ride
comfort not only based on motion but also on their expectations with regard to the class of service that
they have purchased. The duration of the trip has not been demonstrated to be a direct factor in
predicting comfort (with the possible exception of kinetosis), but the anticipated duration of the trip is
related to the types of activities passengers expect to accomplish while on board. Passengers on trips
of more than a few minutes may expect to read, write, eat and drink; on trips of longer duration they
will expect to sleep. To the extent that ride-induced vibration interferes with these activities,
passengers may rate differently the comfort of vehicles with the same motion environment but different
expected levels of service or different trip durations. Passengers are likely to judge comfort based on
the interaction of vibration with factors such as acoustic noise, temperature, humidity, air quality and
seat design.
