A NTUA Diploma Thesis titled “Critical Impact Factors of pedestrian traffic in Athens Downtown” was recently presented by Loukas Stroggylis. This Diploma Thesis revealed that the factors affecting pedestrian traffic are significantly related to the motorized traffic, as well as road infrastructure, land use and Covid-19 Pandemic. After crucial conclusions to quantify the influence of each variable were drawn, comments were made on the positive effects of pilot mobility interventions, critical issues were considered and finally, proposals were made for the improvement of the pedestrian traffic in the center of Athens and for further research.
