The Netherlands have come up with a very good technique to give drivers more visibility in the dark, as many road accidents happen during the dark, when visibility is less.
Their solution–glow in the dark paint. As a part of the Smart Highway project, the N329 in Oss was the first trial. The glowing lines are aimed at increasing night visibility and safety.
The paint, charges up using solar energy during the day and can glow for up to 10 hours in the dark. This provides the driver very good visibility in the dark compared to normal paint, and does not use electricity at all.
There are other ideas as well under the Smart Highway Project. For example, the temperature sensitive paint, a transparent paint that would become visible if the temperature drops, so the driver is aware of the cold road surface.
One major factor kept in mind was not using electricity, but at the same time increase visibility on the road. If tests are successful, this could become a worldwide success and the nights could never be dark for road users.
