Due to the covid-19 pandemic, the TrafficFluid project had suffered some delays, mainly due to hired foreign collaborators who could not make it to Greece. This has caused some delays in our planning and necessitated a short extension of the project duration. Gratefully, ERCEA (European Research Council Executive Agency), our funding agency, recognised this need and granted to the project an extension of 6 months. This moves the ending date of TrafficFluid to 31 May 2025.
