Crashes Increase at New York State’s Roundabouts

By Tim O'Brien | June 28, 2011

Drivers entering a roundabout who fear they’re about to crash are not paranoid.

Although the rotaries are built to ease congestion and lessen serious injuries, data obtained by the Albany Times Union show the number of collisions increased after most of the roundabouts opened in New York State’s Capital Region.

Crashes increased at 15 of the 20 roundabouts built where a previous intersection existed, with fender benders even more likely to rise, sometimes dramatically, at two-lane rotaries. And while crashes were reduced at all the single-lane roundabouts built by the state, they rose at almost all those built by counties and towns.

Aggressive drivers are speeding through rotaries and failing to yield the right of way, said Mark Kennedy, director of traffic and safety for the state Department of Transportation in the Capital Region.

“We have found that single-lane roundabouts definitely reduce accidents,” he said, referring to the state rotaries. “With multi-lane roundabouts, some are better, some are worse. There are two that are somewhat problematic.”

In Malta, the roundabout at Route 9, Route 67 and Dunning Street went from an average of 7.8 crashes a year before the rotary to 45.7 a year afterward. In Bethlehem, the number of accidents at New Scotland Road and Route 140 jumped from an average of 9.6 a year to 38.3.

Two years ago, the state changed the signs and pavement markings at the Malta roundabout to help lessen the number of accidents.

“Those measures were not effective,” Kennedy said.

Accidents in roundabouts tend to be less severe than at intersections with traffic lights. Rather than crash into each other head on or smack together in a T-bone crash, as drivers making lefts at conventional traffic lights often do, drivers in roundabouts tend to sideswipe and rear-end each other.

“The potential for high-speed, severe accidents is eliminated,” Kennedy said.

At the Malta Diner, owner Steve Gouvis has a close-up view to the Capital Region’s most treacherous roundabout. He said it has greatly lessened congestion but he is not surprised to hear crashes have risen.

“You hear a lot of honking during the course of the day,” he said. “They control traffic effectively. You never have to wait more than five, six, seven seconds. They do work. I was a big skeptic.”

But Gouvis said drivers appear not to always know the driver already in the roundabout has the right of way over those entering.

“Most of them are minor accidents from people not accustomed to handling roundabouts,” he said. “It’s a hell of a lot safer than making left turns.”

At the Bethlehem roundabout, town resident Andrew Wickert said he became one of the accident statistics after the rotary opened. About a year ago, he rear-ended the car in front of him when he turned to look at traffic coming up alongside him and didn’t realize the person in front of him had stopped.

“What I’ve learned is to stay in the far lane,” Wickert said. “Even though I am a statistic, I am for it just because it keeps the traffic moving. Before, it was worse with the stoplights.”

This summer, both the Malta and Bethlehem roundabouts will get additional signs telling drivers to “Yield to All Lanes in the Circle.” Markings that narrow as drivers approach the roundabouts will be added to the pavement to give drivers the impression their speed is increasing and they need to slow down.

In Bethlehem, the previous intersection was changed from one lane in each direction to two to reduce congestion. The result, however, has been that drivers enter the roundabout going too fast, Kennedy said.

Variable message boards warning drivers of their speed will be placed there this summer to get motorists to slow down, he said.

“We’ve learned quite a lot about the design and operation of roundabouts” over the past five years, said James Boni, assistant to the state DOT’s regional director. “If we were to design these problematic roundabouts today, we would have designed them quite a bit differently.”

In reviewing crash data, DOT officials said they learned the accidents are not being caused by older people or those from outside the area.

To fully reduce crashes, drivers need to be more careful, said Carol Breen, a DOT spokeswoman.

“People do need to watch the pavement markings, watch the signs and be cognizant of their speed,” she said. “People need to be very cognizant about yielding. If we can get at that driving behavior, we can bring these accidents down
