London, June 19 : The city of Philadelphia in the United States has come up with a novel solution to fight speeding motorists - the use of optical illusions that simulate road humps to fool drivers and get them to put less pressure on the accelerator. hese virtual humps are part of a city-wide campaign called Drive CarePhilly, which includes more resources for police to catch speeding motorists.
Currently being installed at 100 junctions around Philadelphia, Pennsylvania as part of a campaign against aggressive driving, these images painted on the road would appear as 3D barriers to oncoming motorists, even though the road is completely flat.
"The goal is to change the mindset. The driver sees this in the roadway, and they think that it's some protrusion up out of the roadway, and not a perfectly flat surface. So they slow down before they drive over it," The Telegraph quoted Philadelphia's chief traffic engineer Charles Denny, as saying.
In order to assess if this revolutionary idea is actually making the roads safer or not, the National Highway Traffic Safety Administration will be collecting data of the number of roads accidents.
These fake road humps are the latest innovative measure and have an advantage over traditional "sleeping policemen", which have been criticised for damaging cars, slowing down emergency vehicles, and lowering fuel economy.
