Impact of COVID-19 restrictions on mode use and mode captivity the city of Santo Domingo in Latin America

This paper explores transportation mode choice patterns of a population in Latin America before and during the COVID-19 pandemic based on survey data from the city of Santo Domingo (Dominican Republic). An online survey consisting of two waves was conducted between April and June 2020 among randomly chosen transport system users. The survey consisted of both a stated choice experiment, revealed preference, and psychometric indicators. Hybrid choice models were developed and included two latent variables (1) satisfaction with public transport and (2) the response to COVID-19. The results indicate that there is a strong habit of private vehicle use in the Dominican population. The main deterrents for public transport use are limited capacity and reduced safety (including regarding social distancing). The findings particularly highlight the success of the metro as a public transport mode in the city of Santo Domingo. Both cost and time are significant factors in mode choice, before and during the pandemic, but more so for OMSA bus use than for metro use. One of the conclusions from this study is that ignorin covid-related latent effects on public transport service during the pandemic may yield biased (lower) estimations of Value of Travel Time Savings. Finally, the results also show that mode captivity for public transport users plays an important role during the pandemic. These users have no access to alternative transportation and are obliged to continue using public transport. This implies that governments would be wise to urge transport operators not to reduce capacity and frequency during the pandemic.
