Vital Effects of Applied Lighting Science in Road Engineering

At one of the many traffic nodes that lead to the Paris-Lyon highway, those concerned noticed that the rate of accidents at night is 600% higher than at other nodes whose design does not differ much from the aforementioned node. The matter remained for years without a convincing explanation until, by chance, some of the lighting poles leading to the aforementioned node broke down. Those concerned noticed that the accident rate had decreased significantly, then returned to its previous rate after the defect was fixed.
