At a recent podcast in Break It Down, NTUA Professor George Yannis discusses how the traffic system works, congestion, private cars and public transport. The discussion highlighted that congestion is the norm in modern cities and that improving mobility requires better alternatives to private cars, including faster buses, expanded metro networks, cycling and walking. Special emphasis was given to traffic management, bus lane enforcement, the implementation of 30 km/h speed limits and the role of education and enforcement in changing road safety culture. The discussion also highlighted that the significant reduction in road fatalities in Greece during 2025 demonstrates that consistent enforcement can save lives.
