Recently was reported an air miss at Reagan Airport and one of the factors is Intersecting Runways at that airport. A number of airports across the world have intersecting runways, while a number of them have parallel runways.
As a passenger I am blissfully unaware, or not bothered about my flights taking off or landing on such an intersecting runway, and whether my flight would experience such an near miss.
Any thoughts on the alertness of air traffic controllers in airports having intersecting runways against those with parallel runways? Any other important aspects?

Runways are designed taking into account prevailing wind directions.
Wind doesnβt always blow in the same direction, so the two most common directions are chosen for alignment of the runways.
Hence you get intersecting runways.
It is the job of the air traffic and ground traffic controllers at the airport to ensure that planes donβt come close to each other on the taxiways and runways.
They do an excellent job and that is why you rarely hear of planes running into each other.
The possibility exists that communication between the controller and the pilots in planes are distorted by static or external factors such as pilots being too busy and not paying sufficient attention to the radio. This is why both pilots and controllers are required to repeat what they hear and not just reply βokβ or βRogerβ or βunderstoodβ. Pilots also need to identify their aircraft by the airline and flight number each time they have a conversation with the controller so that the controller can be sure that his instructions have been heard by the pilot to whom they are addressed.
But in case the pilots are battling a sudden unforeseen emergency, such as a bird strike or loss of engine power or unexpected wind shear, it is entirely possible their attention to radio communication is reduced and then incidents/accidents happen.

Thanks very much for the detailed answer.

To add to Vivi's detailed answer, when there are parallel runways, one is usually being used for take-offs and the other for landings. Intersecting runways usually mean a lack of space. When there are two (or even three) runways serving different directions, they usually meet close to their apexes, forming either a V or a triangle.

The Tenerife disaster, from the info I get, was on a single runway, where the one which landed was just about to turn into the taxiway, whereas the other was taking off, and it was a dense fog scenario.

But it was all down to human error, one pilot thinking he had been cleared for take-off. There was also 1976 Zagreb mid-air collision - Wikipedia[^] when an air traffic controller forgot about one aircraft's postion.

Yes. That's the WORST air disaster ever (the Tenerife one). Let's hope nothing surpasses it in future.

Tenerife was a complete fluster cluck, and one pilot should have known better. Single runway, and the KLM pilot was in a hurry due to max hours flight rules. That said, it is always the person in command who is responsible. If you cannot see, if you are not absolutely sure about safety, you stop. Period.
The ATC crew were also completely overwhelmed, and went ahead because everyone wanted to get moving, etc. Look at how the US lost the Challenger... I have not read any of the reports yet, but I will gamble and say this is why the container ship took out the Francis Scott Key bridge in Baltimore...
Years ago, I obtained my bareboat captain license. It was pounded into me that *I* as the captain am the only person responsible for the safety of everyone on board. End of discussion. So, a few weeks later, I'm out sailing with my wife, and we get caught in a thunderstorm. We had our life jackets on and what not, so there was no danger of drowning. But, things got interesting due to my inexperience. Scared the living #$%^%^ out of me.
Safety procedures are everything. They form habit and muscle memory. When you start to try altering them, usually something like "this is going to hurt" comes up in your brain. Guard rails exist for a reason.

I believe that it has been reported the ship that hit the bridge in Baltimore lost power and was just drifting when it happened.
Iβve given up trying to be calm. However, I am open to feeling slightly less agitated.

That is what was initially reported. But the general discussion here is safety. Considering the size of container ships, you would think there would be some redundancy in their systems. I'm looking forward to the NTSB report.

It's far more dangerous getting to the airport. Don't sweat it. Up until Boing screwed up (deliberate typo), I was doing some reading on air traffic safety statistics. Considering the growth of air travel over the last 20 years, the safety record is simply incredible. Not only have procedures been updated, there is more safety equipment out there. Most airports have ground tracking radar to monitor their tarmacs and taxi ways.
I live north of Atlanta and our airport is the busiest in the world. We have 5 huge runways, all parallel. Not too much cross runway traffic, but aircraft do have to exit the runway to the concourses. So, it's a taxi situation. It is a finely orchestrated dance but predictable. My house is under the northern approach for the airport. During the evening, I see hundreds of a/c descending and departing from the area.
I flew into Kansas City years ago, and it scared the living daylights out of me.

Nice to know.

Exiting the runway to the concourses, is indeed time-critical. Have seen one such intersection at Zurich Airport.
My first flight was in November 1996, in India, just a couple of weeks after this - 1996 Charkhi Dadri mid-air collision - Wikipedia [^]. Was holding on to dear life throughout my flight. Now, after many years of flying, fear of flying has reduced.
