Drones have been able to go 80+ MPH for years. That doesn't change anything.

If a certain number of cars each year just don't see a full-sized locomotive, you can bet a much larger number of them won't see a robot preceding it. Add to that the likelihood of just such a collision resulting in a disabled wreck on the tracks...

You can have them with battery power and RF to cellular communications to central dispatch who then can use the footage combined with some sort of AI that detects motion (IE something stuck on the tracks/not moving after a set time), and you could use this for all railroads. I am sure the cost of an RF based camera sending a cell signal (since most of the US has 4G service now) is much lower than a drone.This.
MCL1981 wrote:Oh sure. And who exactly is going to monitor 100,000 security cameras all day and all night? That sounds neat, but it is technologically, logistically, and practically ludicrous. People are going to drive their cars in front of moving trains. There is nothing that will stop that or prevent the collisions. All this drone and camera stuff is absurd.Again, I work with modern AI driven tech. It is a fairly easy problem to say "Stuck" since you only need the AI to sense if an object does not move after a small period, so you don't have a human operator unless the AI signals dispatch to let the human know to put the camera on view.

I can see that would be a good place to try it out.
MCL1981 wrote:Most collisions aren't vehicles stuck on the tracks. They're dumbasses that just drive around the gates into the path of train. They connect be detected, and there is no stopping a train in that amount of time. Exercise in futility.I'd rather the judicial branch just got more funding for more judges and clerks, so suits could be dismissed much more quickly, but I see your point too.
State and federal law should simply prohibit civil lawsuits when the crossing protection equipment was found to be working properly, and where the engineer was found to have used the horn and lights as required. If someone is stupid enough to drive their car through crossing gates and get hit by a train, frankly the gene pool is better off without them.

MCL1981 wrote:Plus the cost of 4G service to each unit. Plus the cost of a few thousand new employees to monitor these useless cameras all day. Not a single grade crossing collisions will be prevented. Not a single life will be saved. And it will simply increase the railroad's liability in a lawsuit. It's a horrible idea that changes nothing.4G is cheap, and the data rates wouldn't be high most of the time anyway. Who the hell is going to watch cameras? It's all about vision systems these days. Vision systems watching every camera, bouncing the suspect ones to the dispatcher and maybe even setting the approaching signals to restricting if it feels things are REALLY suspect and there's not enough time for human intervention.
