A study released Tuesday by the cycling advocacy group Transportation Alternatives finds huge gaps in traffic safety enforcement in New York City.

The analysis, which was based on known rates of driver infraction and summonsing by the New York City Police Department, shows that a driver could speed every day in the city and only get ticketed once every 35 years.

It also shows that while the number of traffic fatalities caused by speeding increased by 11 percent between 2001 and 2006, there was a 22 percent decrease in the number of summonses issued in that period.

Additionally, the study finds that police and enforcement cameras catch one out of every 438 cars running red lights.

The group recommends the creation of an Office of Road Safety, that the Department of Motor Vehicles distribute points from the time of conviction and not retroactively from adjunction and that the officers should be patrol areas of frequent crashes.

"There still remains much more that the mayor and the city can do to reduce deaths, reduce injuries, and bring order and justice to the New York City streets," said Paul Steely White of Transportation Alternatives.

Police Commissioner Ray Kelly and Mayor Michael Bloomberg disputed the group's findings.

"We have a safety record in the city that is the envy of other big cities," said Bloomberg.

"I don't know what they're talking about. In 2007 and 2008 we issued 1.2 million moving violation summonses. As the mayor said, we're at the lowest number of vehicle fatalities," said Kelly.

Transportation Alternatives says more than 270 New Yorkers are killed each year in traffic accidents and another 50,000 are injured.
