Dear Collegue, I hope to find yourself in good health. Inside the 20th International Conference on Computational Science and Its Application, to be held in Cagliari, Italy in July 1-4 2020, we organized the workshop: Advanced Transport Tools and Methods - A2TM http://www.iccsa.org/workshops The Local Organizing Commitee is doing a great job laying the foundation for a great conference. We are not experts on epidemics and, in order to be sure, it is better to observe the evolution of the phenomenon in order to take better decisions. For this reason we decided new deadlines: ·       full paper submission 26 April 2020 for our Workshop Transport and Mo, the sessions can have different deadlines; ·       notification of Acceptance 24 May 2020; ·       submission deadline for camera ready paper and registration 15 June 2020. In last days the submission flow increased a lot, this means that in all cases the proceedings (Springer LNCS) will be published. Due to the deadline extension, the volumes will be published after the conference. I hope that in the summer, with the hot temperatures of Sardinia, the situation will be solved, but in next weeks we will continue to analyse the evolution of the situation and we will inform you. Best regards, Massimiliano Petri and Antonio Pratelli
