Area of Science:

  • Transportation science
  • Human factors engineering

Background:

  • Helsinki's underground system, planned for over 20 years, was set to open in 1978.
  • A six-coach experimental line was built in 1972 to test the system.

Purpose of the Study:

  • To analyze the experimental coaches from an ergonomics perspective.
  • To evaluate passenger experience and identify areas for improvement in the train design.

Main Methods:

  • A simulated travel experiment was conducted with subjects.
  • Passenger behavior, entry/exit, and feedback were recorded via TV, film, and questionnaires.

Main Results:

  • Passengers prioritized speed, cost, and comfort, with speed demands unmet.
  • Criticisms included insufficient handles/supports, narrow passages, and limited goods space.

Conclusions:

  • The experimental train layout did not fully meet speed requirements.
  • Design modifications for doors, handles, seating, and space are proposed based on ergonomic analysis.
