Why is it important?
On the one hand, barriers prevent or mitigate head-on collisions and off-road crashes. On the other hand, they reduce the available sight distance. The both effects must be considered before adopting this countermeasure.
Perspectives
This methodology provides a tool to evaluate beforehand the potential effects of the sight distance reduction of installing median barriers to separate driving directions.
