Much like a roller coaster, amusement ride incidents in New Jersey are up one year and down the next. In 2014, they were up again.

There were 139 amusement ride accidents reported in 2014, according to a NJ Advance Media analysis of Department of Community Affairs data. That's up from 113 incidents reported the year before.

Still, the 2014 figures are not as high as in 2010 when 167 incidents were reported to the department.

Another bit of good news is that the department received no reports of serious injury or death last year. Since 1997, there have been five amusement ride-related deaths in New Jersey with the most recent in 2011 when an 11-year-old girl fell from a ferris wheel in Wildwood.

Just like in years past, Action Park in Vernon tops the list with 25 accidents reported in 2014. The park announced Thursday that it would soon launch the longest water slide in the world.

Action Park's 25 accidents in 2014 are slightly more than the 19 it (then known as Mountain Creek) reported in 2013. However, both figures are a vast improvement compared to 2012, when the park reported 70 accidents.

To put it in context, Six Flags Great Adventure and its adjoining water park, Hurricane Harbor have a total of 69 rides and draw in more than 2 million visitors every year. In 2014, both parks reported a total of 11 accidents-- less than half than Action Park did.

In addition, the rides with most incidents reported in 2014 are both in Action Park-- the Tarzan Swing, where riders swing themselves using a rope and drop into water, and the Cannonball Falls, where riders go down an enclosed water tube and drop down 10 feet into a pool.

Many of the incidents that happened on the Tarzan Swings were due to patrons attempting to do flips and landing wrong, according to the data.

In the eighties and nineties, Action Park had a storied reputation for being accident-prone due to the high number of injuries reported there, earning it the nickname "Traction Park."

Other parks

The descriptions given by ride owners to the department for each of the accidents suggests that most incidents were minor bumps and bruises.

Some visitors complain of pain after a ride is over, like a July 5, 2014 incident that happened at Six Flags' Zumanjaro drop ride where the rider complained of "neck and back pain after riding."

Others simply trip, like one person did at the Laguna Kahuna water playground at Clementon Park and Splash World on July 21, 2014. According to the incident description, the patron "tripped on a hole in netting and hit her right front tooth on structure."

Sometimes, a ride exacerbated a medical condition. For example, after riding a Tilt-A-Whirl on June 1, 2014, one patron simply said, "Stop the ride, my heart."

A few were because the patron did not follow instructions, like in August 24, 2014, when a guest going down the Sidewinder Water Slide in the Land of Make Believe let go of the tube handles before the ride was finished causing the rider to slide out of the tube.

Mechanical errors were rare. The Zoom Phloom log flume ride at Surfside Pier had an eventful summer in 2014 when a malfunction caused the ride to break down four times. Two of those incidents led to guest having to be removed from the ride.

The Data

NJ Advance Media received the data through an Open Public Records Act request and added it to our existing accident database from last year. It includes all incidents from 2010 to 2014.

For traveling ride or rental companies, we used the owner company as the name of the park in our database. We then categorized each ride by type, creating our own categories that were more specific than the ones standardized by the American Society for Testing and Materials (ASTM) International.

By law, ride operators and owners are supposed to report within 24 hours any "ride-related injury requiring first aid, or any mechanical malfunction, or an emergency evacuation of the ride"
