STUDy OF VEHICLES UTILITIES AND LOAD-UNLOADING FACILITIES OF CITY PUBLIC TRANSPORT BASED ON ERGONOMICS ASSESSMENT

Abstract

This study was aimed at assessing; the level of ergonomic values of public utility vehicles from the side of anthropometry, the level of ergonomics public transport from the side of anthropometry, and reviewing QFD (quality function deployment) the priority of the technical dimension based on the attributes of vehicles utilities and facilities of the public transport. Data collection is done by measuring the level of interest, satisfaction, and future expectations.  Anthropometric data and the level of improvement priority are examined by modifying GFD matrix. Ergonomic level results presented that 95% of users satisfied, safe, and comfortable. Vehicles utility and load-unloading facilities of public transport with a confidence level of 95% shows the anthropometric dimensions; hangar doors 104.78 cm high, 49.53 cm tall ladder first, second ladder 49.53 cm high, 24.25 cm wide staircase, seat width of 36.21 cm, 44.45 cm seat height, backrest height 27.08 cm, length seat 224.4 cm. QFD assessment based on the attribute utility  Cohen’s scale and load-unloading facilities of the vehicles representing the order of improvement priorities; (1) facilities stop, (2) material seat, (3) access to up / down, (4) high chairs, (5) the sidewalk, (6) street lighting, (7) high-hangar door, (8) the quality of material , (9) air circulation, (10) the lighting in the room, (11) traffic signs.
