Patient Journeys in a Pop Up eye clinic

CASA have been working with Moorfields Eye Hospital to explore the potential for the use of pop-up eye clinics in retail outlets (Brent Cross) to catch up on COVID appointment backlog. Time motion data (x,y data ever 10 seconds) from approximately 4000 patient journies and 4 different activity layouts are available. This project would explore different ways of analysing trends in patient throughput over time and space. Requires data visualisation to inform communication of trends and or data analysis to extract meaning from the data.
