Traffic calming is the use of a variety of traffic safety devices to improve road safety for all users, including pedestrians, cyclist, and motorists. In addition to slowing drivers down and reducing speeding, traffic calming solutions also reduce the number of road fatalities and makes cities safer. Study after study demonstrate that slower speeds reduce the likelihood of vehicle crashes and significantly reduce the probability of fatal or serious injuries. Traffic calming devices include driver feedback signs/radar speed signs, speed humps, and speed cameras.


Radar speed signs can make a difference

On streets where radar signs are installed, drivers really do slow down. Landmark studies across the world demonstrate that speed display signs are a powerful tool for safer roads.

The Effective Deployment of Radar Speed Signs, conducted on behalf of the US DOT and State of California compiled effectiveness data from studies around the country and documented:

  • In South Dakota the percentage of speeding vehicles was reduced by 20-25%
  • In Riverside, CA, drivers slowed by around 6 mph near speed trailer
  • In South Korea, speeders were reduced from 27% to 10% with speed signs
  • In Santa Barbara, CA average speeds were reduced by 10%
  • In work zones, signs reduced the number of speeding truck drivers by 24%

The Stationary Radar Sign Program Report, Bellevue, WA found that:

  • A significant number of motorists chose to correct their speeds
  • Vehicle speeds were reduced by between 1-6 mph
  • Signs continued to be effective even up to 8 years after initial installation
  • Speed display signs were effective in addressing speeding and alerting motorists

A study on the effectiveness of feedback loops, published in Wired Magazine found that:

  • Speed displays installed in one community resulted in drivers slowing an average of 14%
  • On average, drivers slow by about 10%
  • The effect of radar speed signs continues to last even miles down the road

The goal of installing traffic calming devices is to improve safety on roads, in neighbourhoods, and on highways. Over decades of use, radar speed signs have proven to lower driver speeds, reduce casualties, and save lives.

According to the World Health Organization (WHO), close to 1,250,000 people die each year as a result of road traffic crashes. Without action, road traffic crashes are predicted to become the 7th leading cause of death across the world by 2030.

Today’s roads are a dangerous place

⇒Nearly half a million people were injured in road traffic accidents in India in just one year.

⇒India’s roads saw more than 140,000 traffic-related deaths in 2015, a number that has been growing annually.

An average of 400 people are killed on India’s roads every day.

More than half of road accidents in India are caused by speeding drivers.

Close to 1,250,000 people die each year around the world because of road traffic crashes.

⇒90% of the world’s fatalities on the roads occur in low- and middle-income countries, despite the fact that these countries only house around half of the world’s vehicles.

Around 50% of traffic related deaths are to “vulnerable road users”: pedestrians, cyclists and motorcyclists while traffic injuries are the leading cause of death among young people aged 15-29 years.

⇒Without action, road traffic crashes are predicted to become the 7th leading cause of death across the world by 2030.

77% of accidents in India are the fault of the driver.

Reports published by UNESCAP show road accidents as a leading cause for death and disabilities in India.

Road accidents don’t only affect personal lives; they are estimated to reduce India’s GDP by 3% each year.
