Research and technological development project – SOCIAL DISTANCING MONITORING SYSTEM (SDMS) – launched as part of the fight against the COVID-19 pandemic.

The article “Mapping Crowds in Open Spaces in the Context of Social Distancing and COVID-19 Transmission,” presented in February 2021, aims to develop a solution for controlling and monitoring social distancing, primarily intended for outdoor environments, which can be installed on IoT devices attached to streetlights, light poles, or other types of infrastructure.

The proposed system detects and enumerates mobile phones or similar devices by analyzing Wi-Fi and Bluetooth radio frequency (RF) signals. Based on this data, it geolocates the devices to map crowd density and occupancy patterns.

ABSTRACT:
“Public or private spaces exceed occupancy limits when they surpass their defined capacity guidelines, particularly those established by health authorities for crowd concentration. Contexts involving changes in the number and layout of available spaces, namely due to social distancing regulations, directly affect density and occupancy rates. Counting individuals across specific areas or geographic zones enables the assessment and alerting of contagion risks by verifying compliance with distancing rules. The proposed system detects and counts mobile phones or similar devices by tracking their Wi-Fi and Bluetooth communications. By analyzing radio transmission signals, it geolocates these devices and maps crowds based on their occupancy densities.”
