What is Thickness

Data collected by the United Nations (UN) suggest that infections arise after a close contact with infected people through nasal and oral secretions released when an infected person coughs, sneezes, or talks. In public transportation buses, an important amount of people gather every day for long periods of time, making the air pollution inside these transportation systems a major risk for transmission. Therefore, the objective of this chapter is to know criteria and strategies for a conceptualization of an air-extraction system inside public transportation buses, based on the detailed study applicability of the 1) product-user interaction (technical data, dimensional relationship, and evaluation); 2) creative process, ideation, definition, evaluation, and structuration; and 3) sustainability, technical specifications, ergonomics, and production by means of understanding the design's limits and effects.
