“…Naturally increasing the ventilation rate can speed up the CO 2 decay and thus it is also possible to use smart plants to obtain insights into the ventilation rate used in the space. For example, increased ventilation rates have been suggested as a way to mitigate risks of COVID-19 spread [25], [26].…”

Humans tend to spend most of their life indoors making the quality of indoor environments essential for human health and well-being. While several solutions for monitoring the indoor environment have been proposed, ranging from infrastructure-based monitoring solutions to cameras, these tend to require separate installation making the sensors difficult to maintain and upgrade. In this paper, we introduce the idea of using smart plants as an easy-to-deploy and affordable solution for monitoring the indoor environment. Plants are typically deployed close to humans and they increasingly are placed in containers that integrate sensors, such as soil moisture, temperature, humidity, and CO 2 sensors. We demonstrate how these sensors can be used as an alternative technology for monitoring -and enriching -indoor spaces without needing to install proprietary sensors or other technology. Specifically, we show how smart plants can be used to estimate overall CO 2 accumulation, occupancy information, and whether people use protective face masks or not. We also establish a research roadmap for the use of smart plants to monitor indoor environments.

“…However, it is generally agreed that contact between people is the primary way transmissions occur (Rana, 2022). This is especially true if people share a space for some time (Liu, 2022) where they encounter each other. This is a very rough measure, as not all contacts are equal in terms of the risk of infection.…”

“…For example, a hug between two elderly persons, who are not in the same household and do not have any other risk factors (Fields, 2021), is a far less risky contact than sharing a meal with a friend who is infected with COVID-19. The number of contacts, which we can call contact intensity, is an essential parameter in spreading infectious diseases (Liu, 2022). The more contacts, the more likely the pathogen will spread.…”

Is the multimodality related to urban mobility changes during the pandemic?

COVID introduced new considerations and changed the urban mobility ecosystem and perception. During the pandemic, mobility patterns change according to several factors. Few studies have investigated the impact of the mobility system features on the dynamic of people during the pandemic. This research attempts to understand the relationship between the urban mobility system advancement and the behaviour of people throughout different stages of the pandemic. This study uses big data for day-to-day mobility in different regions in Germany and employs the correlation coefficient matrix to analyze the impact of the smart mobility indices on the trends of mobility and the number of contacts between people. The study covers the whole pandemic period, from 2019 to mid-2022, to derive a pandemic crisis travel mobility patterns for each wave. Overall, a negative correlation between developed mobility systems and mobility trends means that the smarter cities and regions have, the fewer people tend to travel; the second wave marks the greatest mobility decline in correlation with more advanced mobility systems. While sophisticated and advanced mobility systems are often cited as having more attractiveness and a positive effect on the traveller's satisfaction, our findings suggest no clear and discernible impacts during the pandemic were observed. On the contrary, more multimodal trips, sharing options, and smarter mobility, in general, were associated with less mobility of people, yet it does not interfere with the contact between people, during the different stages of COVID in Germany.
