A particular type of indoor compartment, land transport cabins (LTCs), specifically those of trains and buses, was surveyed. The global rise in commute and in-cabin exposure time gives relevance to the current study. This study discusses indoor climate (IC) in LTCs to emphasize the risk to the well-being and comfort of exposed occupants linked to poor IEQ, using objective assessment and a communication method following recommendations of the CEN-EN16798-1 standard. The measurement campaign was carried out on 36 trips of real-time travel on 15 buses and 21 trains, mainly in the EU region. Although the measured operative temperature, relative humidity, CO2, and VOC levels followed EN16798-1 requirements in most cabins, compliance gaps were found in the indoor climate of these LTCs as per ventilation requirements. Also, the PMV-PPD index evaluated in two indoor velocity ranges of 0.1 and 0.3 m\/s showed that 39% and 56% of the cabins, respectively, were thermally inadequate. Also, ventilation parameters showed that indoor air quality (IAQ) was defective in 83% of the studied LTCs. Therefore, gaps exist concerning the IC of the studied LTCs, suggesting potential risks to well-being and comfort and the need for improved compliance with the IEQ and ventilation criteria of EN16798-1.<\/jats:p>","DOI":"10.3390\/atmos15050589","type":"journal-article","created":{"date-parts":[[2024,5,14]],"date-time":"2024-05-14T08:59:37Z","timestamp":1715677177000},"page":"589","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":7,"title":["A Field Survey on Indoor Climate in Land Transport Cabins of Buses and Trains"],"prefix":"10.3390","volume":"15","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-2780-5418","authenticated-orcid":false,"given":"John","family":"Ogundiran","sequence":"first","affiliation":[{"name":"Department of Mechanical Engineering, University of Coimbra, ADAI, Rua Lu\u00eds Reis Santos, P\u00f3lo II, 3030-788 Coimbra, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5948-5303","authenticated-orcid":false,"given":"Jean-Paul","family":"Nyembwe","sequence":"additional","affiliation":[{"name":"Department of Mechanical Engineering, University of Coimbra, ADAI, Rua Lu\u00eds Reis Santos, P\u00f3lo II, 3030-788 Coimbra, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4716-979X","authenticated-orcid":false,"given":"Anabela","family":"Ribeiro","sequence":"additional","affiliation":[{"name":"Department of Civil Engineering, University of Coimbra, Rua S\u00edlvio Lima, P\u00f3lo II, 3030-790 Coimbra, Portugal"}]},{"given":"Manuel","family":"da Silva","sequence":"additional","affiliation":[{"name":"Department of Mechanical Engineering, University of Coimbra, ADAI, Rua Lu\u00eds Reis Santos, P\u00f3lo II, 3030-788 Coimbra, Portugal"}]}],"member":"1968","published-online":{"date-parts":[[2024,5,13]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"1","DOI":"10.1016\/j.ijsbe.2016.03.006","article-title":"Impact of indoor environmental quality on occupant well-being and comfort: A review of the literature","volume":"5","author":"Arif","year":"2016","journal-title":"Int.
