Design of flexible partitions for physical distancing in buses in Colombia during COVID-19
Abstract
The scientific community recognizes that the transport of cargo and passengers is a key factor in the spread of infectious disease pandemics. In particular, during the COVID-19 pandemic, public transport systems have been considered high-risk environments for the transmission of the virus; therefore, in many places around the world, restrictions have been imposed on passenger transport. Although different aspects of transport have been studied during the pandemic, there are still gaps in knowledge about the effect of different means of transport and specific interventions for vehicle design strategies to reduce transmission rates. In this context, this article presents the process of co-designing a flexible partition to divide seats on articulated, standard and complementary vehicles of a bus rapid transit system in a Colombian capital city as a vehicle design strategy to contain the spread of the virus and generate a physical barrier when the physical distance of one meter, as required by national regulations, was unable to be maintained. The design methodology followed an incremental and iterative process of 6 stages until reaching the final design. The process began with the identification of the need, the establishment of the design requirements and determinants, the generation of proposals framed within the requirements, the performance of functionality and cost feasibility tests and the building of the prototype with the chosen design. Additionally, a participatory evaluation was carried out based on the identification of relevant aspects, doubts, criticisms and new contributions to the prioritized prototype. Finally, the generated prototype met the design requirements in addition to a significant cost reduction of 70% compared with the initial proposal by the bus rapid transit. The low cost allows the implementation of the partition throughout the bus fleet, but controlled observational and clinical studies on the effectiveness of the partition in the prevention of COVID-19 are required.
