Mayor Michael Bloomberg announced two new pilot programs Thursday to decrease traffic related deaths. They're a response to the United Nations's new Decade of Action for Road Safety campaign.

One program lowers the speed limit in some of the city's busiest neighborhoods. The first change will be a 10 MPH decrease in the Claremont section of The Bronx, down to 20 miles an hour from 30.

The second program introduces the new signs. City Department of Transportation Commissioner Jeanette Sadik-Khan and Mayor Bloomberg say the installation of new electronic signs will alert drivers to the city's current speed limit of 30 miles per hour.

The boards will flash a warning to "slow down" if drivers exceed the limit. It will also be accompanied by a skeleton silhouette.

"The message is speeding kills. And we need to take it seriously. If you are hit by a car going even 10 miles over the city's posted limit of 30 miles per hour there is a 70 percent chance a pedestrian will die. If you maintain the speed limit of 30 miles per hour, there's an 80 percent chance the pedestrian will live," Sadik-Khan said.

"We have to be smart and use technology to implement reforms and to get people to obey the law. The best thing would be if we never issued a ticket. The best thing would be people obeyed the law," Bloomberg said.

The new programs are expected to go into effect this summer.

Officials say 13 people are injured or killed each day on city streets.
