(New York, NY -- WNYC) Eight months after a 12-year-old girl was killed crossing a street, safety upgrades have been completed at 14 locations along a notoriously dangerous street on Manhattan's Lower East Side.

New York City Department of Transportation Commissioner Janette Sadik-Khan unveiled the revamped street on Thursday. The pedestrian crossings have been overhauled and car travel lanes have been re-engineered. Although the impetus for the redesign was the January 2012 death of Dashane Santana, over 700 people have been injured near that stretch of Delancey Street between 2006 and 2009.

Teresa Pedroza, Santana’s grandmother, said that while she's glad the street work has been completed, more could be done. “There are at least a good five or six schools in the immediate area,” Pedroza said. “You have at least eight lanes of traffic and there should be a crossing guard for these kids, especially when it’s time to come out of school.”

Sadik-Khan agreed that the redesign isn't enough -- but she wants more than a crossing guard. "We’re working hard to get speed camera legislation passed in Albany which will go a long way to help us address the problem of speeding and fatalities," she said, "which are a quarter of the traffic fatalities on New York City streets."

A recent city report revealed traffic fatalities are up 23 percent in New York City over a recent twelve-month period, although overall total traffic fatalities are down about 20 percent since 2003. The recent tick upward in New York mirrors a national trend. The federal government projects that traffic fatalities were up 9 percent in the first six months of this year.

Although no immediate reason was given for the increase, Sadik-Khan reiterated drivers need to obey the law. “The problem that we have on New York City streets is that people are speeding, they are running red lights, they are drinking while driving," she said. "These are all significant problems that we need to address.”
