Indoor Environmental Quality Assessment of Train Cabins and Passenger Waiting Areas: A Case Study of Nigeria

John Omomoluwa Ogundiran,
Jean-Paul Kapuya Bulaba Nyembwe,
Anabela Salgueiro Narciso Ribeiro
et al.

Abstract: The adequacy of the indoor environmental quality (IEQ) in mass transit microenvironments is crucial to the well-being of exposed commuters. By 2050, many developing tropical countries will host even more megacities, which will feature an increase in people mobility and higher occupancy density. The paucity of IEQ studies, the technology gap, and inadequate policy measures to assure safer and sustainable mobility in many developing tropics have reinforced the current study objective. Also, the recent COVID-19 p… Show more

“…The smaller the mean air age, the lower the fresh air flow rate (Q), and vice versa. The current study findings are akin to those of Ogundiran et al (2023) [29] on the IEQ of train cabins, in which ventilation parameters were inadequate in 9 of the 15 LTCs studied, besides other IEQ gaps. In comparison to buildings, given the high occupancy density in transport cabins, there is a need to improve the ventilation in the cabins through an increase in the fresh air flow rate per person and ACH.…”

“…The equipment sensors capturing volatile organic compounds (VOCs) in the cabins are delimited following the IAQ scale in the BME 680 datasheets regarding indoor air quality [60]. Evaluation method of the ventilation parameters: The fresh air flow rate and air exchange rate were calculated using Equations ( 1)-(4), using the estimated mean outdoor and mean measured in-cabin CO 2 levels during each trip, similar to the methods applied by Ogundiran et al (2023) [29]. The maximum occupancy passenger count was at full occupancy for only seating passengers, as was experienced in the field survey, including the estimated internal cabin volumes for the buses and train passenger cars.…”
