Problematic Speed for road safety.
Specifically: Excessive speed, that is to say driving at a speed higher than the maximum permitted speed as well as Inappropriate speed, which is defined as driving at excessively high speeds given the traffic situation, infrastructure, weather conditions and/or other special circumstances. Speed is one of the most important causes of road accidents: 10-15% of all road traffic collisions and 30% of fatal injury collisions are the direct result of excessive or inappropriate speed.
An increase in speed by 10 km/h leads to a risk of a fatality of 220% of the initial event, i.e. the risk has more than doubled.
The implementation of infrastructure projects and the identification and rehabilitation of dangerous points on the road network is one of the strategic axes of the RSI.
In a E-77 road axis part, in particular in an area of 4 km of the Chalkida-Psahna road, there has been a high rate of fatal road traffic collisions over the last 20 years due to problematic speed.
The aim of this project was the design of interventions related to infrastructure in order to improve road safety by enabling drivers to control their behaviour.
