The tide is changing with members of the public too. You can see comments from a number of people that support the parks decision and are glad they are focusing so heavily on safety. Some even recognise that rides are doing what they are designed to do (stop when something occurs) and maintenance staff are being vigilant in their inspections.
Go back 5 years ago and the sky was falling anytime any mention of a ride stoppage occurred. It was pretty much exclusively negative comments in response to media articles like this.
The parks should really be capitalising on the change in sentiment from members of the public and drive home the message their safety is paramount. It would absolutely squash alarmist reactions to publications and articles like this. The best way to do this is to demonstrate to the public just what goes on behind the scenes so they can physically see what is involved daily.
There are videos on youtube explaining as much, but it's pretty simple in design if you want to read about it ill post for you. I've simplified it as much as possible, so you get the idea how it works, but it's still a bit of a lengthy read unfortunately. Can't really shorten it any further.
In order to maintain safe distances on rides with multiple vehicles/trains/cars; ride pathways (track, roadways, rivers, troughs, stations, etc) are divided into segments within the operating control system. These segments are usually called zones or ride blocks. A very basic example of this is a load station, the lift, the ride area itself, and the unload station of a roller coaster. Each of these 4 sections of the ride are designated ride zones or blocks. Think of them as literally road blocks that nothing can drive through until cleared.
The #1 function of every block system is to maintain a clear path ahead at all times. This is the fundamental rule that never changes. The control system is designed so that a vehicle cannot physically pass from one segment or block to another without the forward block being free (unoccupied). This is how they maintain a safe distance between multiple vehicles and stop them hitting each other.
Each of these blocks are monitored by the control system and have the ability (via various braking methods) to stop any vehicle from advancing forward in the event of a fault occurring, a timing issue (as in, taken too long for guests to enter or exit vehicles), or simply due to the forward block being occupied by another vehicle. The ride control system will physically stop a vehicle and hold it in position in this block until the way ahead is clear. This is one of the primary purposes of brake zones you see in attractions.
Use a small rollercoaster like Road Runner for example. It is broken up into 3 zones or blocks.
Station. Lift. Brake Zone (on road runner, the free fall section of the track after the lift to the actual physical brakes is considered the brake zone).
For the sake of using terminology that makes it easier to understand; occupied = blocked. unoccupied = free.
In two train operation, train one is parked in the station, loading/unloading guests while train two is held in the brake zone. The Station zone is blocked. The lift zone is free. The Brake zone is blocked.
Train one is loaded with guests and advances out of the station zone on to the lift. The lift zone is now blocked while the station zone is now free. The brake zone is blocked.
Train two, being held in the brake zone has its brakes released and is driven forward into the free station building, parking in the home position and having the brakes applied for guests to disembark. The brake zone is now free, the station is blocked. The lift is blocked.
Train one is nearing the top of its lift climb. The brake zone ahead is now free so the train progresses over the lift hill into the free fall section of the track. The lift zone is now free. The brake zone is blocked. The station is blocked.
Train two loaded with guests dispatches out of the station and into the free lift zone ahead. The station zone is now free. The lift is blocked. The brake zone is blocked.
Train one approaches the brake zone and stops in the brake. The brake zone is blocked, the station is free. The lift is blocked.
Train one has its brakes released, advances into the station and parks in the home position for guests to disembark. The station is blocked. The lift is blocked. The brake zone is free.
Train two approaches the top of its lift climb, the brake zone ahead is free so it continues over the top into the free fall section. The lift is free, the brake zone is blocked, the station is blocked.
Train two stops in the brake zone and is held in position. The station is blocked with train one. The lift is free. The brake zone is blocked.
You have just completed 1 full cycle of each train.
The block control system is like a stop/go traffic controller at roadworks. It's opening and closing the way ahead to allow traffic to pass freely without accidents.
Now, as I said before, remember the block system will not allow advancement forward unless the block ahead is free.
A train in the station cannot dispatch until the lift zone is clear of the second train.
The second train will be stopped on the lift and cannot advance forward over the top of the lift unless the brake zone ahead is clear.
A train cannot be released from the brake zone to enter the station unless the station zone ahead is clear.
Make sense?
The more trains/vehicles/cars you have, the more zones/ride blocks you have. A ride will ALWAYS have more blocks than it has vehicles. You can really see this in action in rides like scooby doo and green lantern. Each of the physical brake positions along the track are block zones.
The ride control system can physically stop a vehicle in each of these zones if the block ahead is not clear. During normal operation it will hold them in this position until the zone ahead clears, then it will allow the vehicle to continue ahead after a brief pause. No doubt you have experienced this in the high zone at scooby doo, or cars queueing before unload at green lantern?
The nature of these rides means they are complex machines with sometimes hundreds of sensor inputs. The default action in any event that the control system detects an error or something is operating out of its control parameters is to stop the ride and go into safety fault. Now it doesn't have to mean an actual physical failure of a component has occurred for this to happen, nothing could be actually broken. It could simply be caused by a vehicle that didn't flag a sensor correctly to notify the control system it has left a block zone, or a car has taken too long to enter or exit a zone and has timed out. These sorts of faults happen multiple times a day and will generally require maintenance staff to attend and reset the fault to allow further live testing to make sure the fault doesn't reoccur and the ride is safe to reopen.
As safety has become paramount over the last few years, pretty much all ride stoppages now result in guest evacuations before faults can be reset and testing can continue. It's an element of increased safety awareness but also down to risk minimisation. So if you were riding an attraction and previously experienced one of these type of faults without being evacuated, the ride was restarted and you continued to the station to exit like normal, it's now largely a thing of the past.
Before it might have been a slight inconvenience and everybody might have continued within a number of minutes, so barely any notice was given to stoppages. Now, with tighter safety control measures, it's very evident when something goes wrong and guests have to be evacuated. The faults haven't changed, they have largely always been the same, it's the procedure that has been updated resulting in significant downtime for what might only be a non issue.
It's the primary reason why I think the parks have to respond now and get on the front foot, explaining their processes to give the public greater peace of mind. Otherwise, media outlets are just going to keep posting drivel like this any time they hear a stoppage has occurred.
It has the potential to go one of two ways; Either it will drive more fear into the public, or people will get sick of the media reports and start to ignore these reports. Having the parks respond would significantly reduce to chance of the former taking hold, while simultaneously helping to turn the tide against poor journalism and the publication of tripe like this.
