Covid-19 need not spell the death of public transport: Learning from Hanoi's safety measures

Abstract

Objectives In contrast to other cities worldwide, the pandemic has not decimated bus ridership in Hanoi. Notably, the Vietnamese capital has mostly relied on the use of face masks and hand sanitizer during travel, instead of requiring physical distancing on buses. This study examines public bus passengers’ levels of compliance with Covid-19 safety measures, and the factors that affect compliance. Methods Face-to-face surveys were administered between 7 September and 3 October 2020, right after the end of the third wave of Covid-19 in Hanoi on 51 bus routes. Exploratory Factor Analysis was carried out to extract factors from attitudinal statements. The extracted factors, passengers’ socio-demographic traits, and their bus use patterns were modelled to determine which variables lead to more compliance with Covid-19 safety measures. Results We found that 100% of passengers wore face masks (which were mandated), albeit 11% did so incorrectly, while only 28% of passengers used the hand sanitizer provided by bus operators (which was recommended but not required). In addition, 38% of passengers carried their own bottles of hand sanitizer while travelling, despite a relatively low risk of contracting the virus. Women, older passengers, and urbanites were less likely to sanitise their hands. Frequent bus travellers behaved like the population at large with regard to protective measures against Covid-19. Conclusions Hanoi's overall measures - full use of face masks and partial use of hand sanitizer - were sufficient to contain three relatively minor Covid-19 waves while still maintaining regular bus operations most of the time. If other cities were able to reach these levels of compliance, most would be in much better position vis-à-vis public transport use during the pandemic (or an epidemic). Our findings suggest that mandates work much better than awareness raising campaigns, although the latter have a role to play.

Why are Hanoi students giving up on bus ridership?

“…The public transport system comprises more than 100 formal bus routes, which are subsidised by the public sector (Nguyen and Pojani 2021 ). While this number sounds high, it is inadequate for a megacity like Hanoi.…”

Seroprevalence of SARS-CoV-2 antibodies among public transport workers in Sweden

“…Simulations using disease spread models have shown substantial and significant reduction in the number of new infections when face mask use is greater than 80% among passengers in public transport ( Grzybowska et al, 2022 ). Such infection control measures can be employed during virus epidemics to assure bus drives’ safety and reduce transmission in public transport ( Nguyen and Pojani, 2021 ).…”

Understanding the perceived behavior of public utility bus passengers during the era of COVID-19 pandemic in the Philippines: Application of social exchange theory and theory of planned behavior

“…This approach guaranteed bus efficiency dependent on the passenger volume and routes. Nguyen and Pojani (2021) assessed the bus passenger's compliance with the implemented COVID-19 protocols in Hanoi, Vietnam. The researchers disclosed a higher level of compliance equated to low COVID-19 cases compared to other cities worldwide.…”
