Traffic enforcement cameras are far outpacing NYPD in ticketing drivers who speed, run red lights, and encroach on bus lanes — pointing to the need for more automated enforcement to make streets safer.

A report from the city’s Independent Budget Office finds that FY 14 revenue from camera-generated tickets in those three categories was $41 million, compared to $14 million from summonses issued by NYPD, based on preliminary data. “The proportion of revenue generated by cameras rose from 38 percent in 1999 to 75 percent in 2014,” the report says.

While tabloid coverage focused on the revenue angle, the takeaway should be that we can now see how much NYC needs automated enforcement to reduce dangerous driving.

According to the Post, speed cameras issued 48,517 tickets in June, the first month when 20 cameras were operational. In one month those 20 cameras nearly eclipsed the 54,854 speeding tickets issued by NYPD through the first six months of the year.

From mid-January to mid-May, when just five speed cams were working, they issued more than 41,000 tickets, according to the city’s open data portal. Through the end of June, NYPD issued a combined 83,066 summonses for speeding, red light-running (26,749), and driving in a bus lane (1,463).

Though NYPD has stepped up enforcement somewhat this year, these numbers really give a sense of how rampant law-breaking is on city streets — particularly when you consider Albany restrictions that limit speed camera operation to school zones during school hours, and only allow tickets when a driver exceeds the speed limit by 11 miles per hour or more. That means in one month 20 cameras covering just a fraction of the city for part of the day caught nearly 50,000 motorists traveling well in excess of the posted speed.

As speed cameras become more prevalent, it might make sense for cops to focus on other dangerous violations, like failure to yield, which don’t involve stopping drivers traveling at high speeds.

NYC is a long way from complete speed cam coverage, of course, and even Albany’s recent authorization of 140 cameras won’t cover most of the city’s 6,000 miles of streets. But it’s clear that a handful of cameras are already doing a lot more enforcement than NYPD. Those 140 speed cameras are going to make a difference, even if we need a lot more to get to zero traffic deaths.
