Street lighting may be considered an obvious means of preventing road traffic crashes, but the scientific evidence for this has been uncertain and many studies are decades out of date. Some even suggest that drivers 'feel' safer on better lit roads and may speed up as a result. But a systematic review by Cochrane Researchers now shows that street lighting does indeed reduce crashes and injuries on the roads.
The World Health Organization estimates that 1 million people die each year on the world's roads and up to an additional 50 million are injured, causing an estimated global bill of $578 billion.
"Road traffic crashes are not just the unfortunate culmination of chance, but are events that can be analysed so that the risk factors are identified and then addressed. Darkness is a risk factor - street lighting is therefore a valuable tool," said lead researcher, Fiona Beyer, of the Institute of Health and Society at the University of Newcastle in the UK.
The researchers reached their conclusions by pooling data from 14 studies on the effects of street lighting on road safety. They found that street lighting reduced total crashes by between 32% and 55%, and fatal injury crashes by 77%.
Without intervention, the number of deaths due to road traffic crashes is expected to reach 2.3 million by 2020. It is thought that nine out of ten deaths will occur in low and middle income countries. But Beyer says the results may also have implications for policy makers who plan to reduce public street lighting under the premise of cutting carbon emissions and costs.
"In the UK, an increasing number of local councils are looking to turn off some public street lighting in a move to reduce costs and carbon emissions. The potential adverse road safety impact of such a policy should be carefully considered in light of our findings," said Beyer.

Researchers at the University of New Hampshire have captured a difficult-to-view singular event involving "magnetic reconnection"--the process by which sparse particles and energy around Earth collide producing a quick but mighty explosion--in the Earth's magnetotail, the magnetic environment that trails behind the planet.
Magnetic reconnection has remained a bit of a mystery to scientists. They know it exists and have documented the effects that the energy explosions can...
Biochips have been developed at TU Wien (Vienna), on which tissue can be produced and examined. This allows supplying the tissue with different substances in a very controlled way.
Cultivating human cells in the Petri dish is not a big challenge today. Producing artificial tissue, however, permeated by fine blood vessels, is a much more...
Faster and secure data communication: This is the goal of a new joint project involving physicists from the University of Würzburg. The German Federal Ministry of Education and Research funds the project with 14.8 million euro.
In our digital world data security and secure communication are becoming more and more important. Quantum communication is a promising approach to achieve...
On Saturday, 10 November 2018, the research icebreaker Polarstern will leave its homeport of Bremerhaven, bound for Cape Town, South Africa.
When choosing materials to make something, trade-offs need to be made between a host of properties, such as thickness, stiffness and weight. Depending on the application in question, finding just the right balance is the difference between success and failure
Now, a team of Penn Engineers has demonstrated a new material they call "nanocardboard," an ultrathin equivalent of corrugated paper cardboard. A square...
