India may soon get luminous highways to enhance road safety- save energy

Some of India’s dark patches could soon get futuristic luminous highways. These highways, costing just 15-20 per cent more than regular highways, do not require any street lights and come to light on their own as a photoluminescent coating similar to glow-in-the-dark paint creates ethereal looking lines that get charged by sunlight.
The Netherlands already has such highways and India could turn to these for the largely unlit road network in the hills, a senior government official said. “It will also work well in foggy conditions and improve overall road safety. The drivers will be guided by glow-in-night lines,” said the official, who did not wish to be identified.
It costs Rs 11-15 per km to build a regular highway in the hilly areas. The luminous highways will not only help save precious energy consumed by street lights but also make the roads safer. Studies have shown that proper lighting can substantially reduce fatalities and crashes, the official said. Most accidents occur between 6 pm and 3 am, according to a government estimate.
The Central Electricity Authority (CEA) reports that 1 per cent of all electricity consumption in India goes to providing public lighting. “This will reduce the demand for lighting on highways and increase transportation safety significantly.
According to a government study, the energy consumption on public lighting will double to 13.2 (terawatt-hours) TWh by 2020 from the level in 2010. Street lights have high hours of use as they are on for over 4,000 hours per year and consume a lot of energy.
The government is also planning to make rumple strips running along the lanes mandatory to alert drivers. Recently, Prime Minister Narendra Modi, during his Mann Ki Baat radio address, said that the government would soon implement a national road safety policy.
About five lakh road accidents take place every year in India in which three lakh people get injured and 1.5 lakh die.
