My suggestion is always "suicide clinics", where you can just walk in. That sounds absolutely horrid, but the point is to catch the people that can be saved by intervention. They take you in, and talk with you, go through medical history, then you have to wait some hours etc. and all that. And if you still wish to die and you're not diagnosed with having some sort of episode, they just let you swallow some pills and then you get to lay on a bed and die.

That'd be way more efficient than just letting people jump from the rooftops and on the train tracks, would save people, would traumatize less people, would cause less suffering; would overall improve the situation. Of course that could be misused, and it would not catch all people. But I'd definitely prioritize getting less people splatter on the sidewalk anyway
