Traffic Congestion on Kifissos Avenue
There is no possibility that the problem on Kifissos will be solved at some point, just as it has not been resolved anywhere in Europe. Europe is full of roads like our Kifissos Avenue. Major
Kifissos: Analgesic Measures for traffic congestion
One of the main causes of inconvenience is damages or crashes that result in the closure of one or more lanes for several hours. This significantly burdens the daily traffic. At two points along the
Road safety performance in Greece
In July 2023, we had a 22.5% increase in road crashes compared to July 2022, demonstrating Greece's poor road safety performance compared to other European countries. Last year, in 2022, our country dropped 2 positions,
