Abstract:

Train is a high efficiency mass transportation which is suitable to increase life quality and support of high citizen mobility. The purpose of this paper is to produce some recommendations of improved railway carriage design which are accessible for disabilities, ergonomics and economics. Firstly, the research started with theoretical studies on the product design development, House of Quality (HoQ), visual displays design, anthropometry, and the needs of disabilities. Next step collected data from the open survey and then form the closed survey of 30 respondents who has physical disabilities and visual impairment to understand the passengers’ need. The results of voice of customers shown that an easy access of disabilities people in the carriage has the biggest negative gap between reality and expectation for 1.16 and then following by space availability of wheelchair for 1.10, the seat numbering for visual impairments passengers=0.85, and the ease of emergency aid=0.71. The HoQ provided analysis of room 1 for customer needs, room 2 for voice of team design, room 3 for relationship matrix, room 4 for benchmarking, room 5 for technical benchmarking, room 6 for correlation matrix, and room 7 for weighted importance and relative importance. The QED results shown that the first rank of relatives importance was distance between seat with score=0.618, the second was colour on seat numbering and train series=0.561, and the third was emergency button=0.439. New design recommendation of carriage design should contain of modified seat layouts, improved wheelchair and aisle space, added guiding blocks, emergency assistance buttons, additional folding chairs, and handrail adjustments. Alternative designs were successfully created and able to increase the seat number of the railway coach.
