sovetskii52 Posted January 31, 2013 Share #26 Posted January 31, 2013 About the alarm system: Actual suiciders won't jump onto the tracks and wait 10 minutes for the train to enter. They will jump seconds before the train reaches them. An alarm system won't help in that case, but it will if someone slips, or faints with enough time for the alarm system to make a difference.

Minato ku Posted January 31, 2013 Share #27 Posted January 31, 2013 Sensors to detect if something has fallen in the track exist since a long time. The Skytrain in Vancouver (1987) or the line D of Lyon metro (1991) have them. When something drops in the track, the traffic shut down. It has some problem at the beginning because the system was too sensible, detecting even little objects. If if that would not stop a suicide or a murder, this would prevents for some people falling in the track to be hit by trains. Link to comment Share on other sites More sharing options...
pjbr40 Posted January 31, 2013 Share #28 Posted January 31, 2013 i dont think it gonna work. the PA has spent millions of dollars for same kind of thing except it over water. when that boat or jet ski got stranded in the area of secure permitter by the JFK, the alarm syatem failed. If this hapen in subway it will still failed. Link to comment Share on other sites More sharing options...
realizm Posted January 31, 2013 Share #29 Posted January 31, 2013 If they can incorperate infrared technology in it where the sensors can read body tempertures on the fly then it could work. The technology is definitely there. Link to comment Share on other sites More sharing options...

itmaybeokay Posted January 31, 2013 Share #36 Posted January 31, 2013 About the alarm system: Actual suiciders won't jump onto the tracks and wait 10 minutes for the train to enter. They will jump seconds before the train reaches them. An alarm system won't help in that case, but it will if someone slips, or faints with enough time for the alarm system to make a difference. To be fair, platform screen doors might not even lower overall suicide rates - they only have the potential to lower suicide by train. If someone is distraught enough to be completely determined to take their life, unfortunately they will merely find another way - and we can't ban everything that could possibly kill someone, lest we forego toaster ovens and bathtubs as well. The best way to prevent suicides is with broader public policy. Also, something like this wouldn't hurt, would be cheap, and could also contact an operator who could alert RCC if someone has already fallen. Double bonus. In fairness, it's basically just a help-point with a "life is worth living" sign on top. i dont think it gonna work. the PA has spent millions of dollars for same kind of thing except it over water. when that boat or jet ski got stranded in the area of secure permitter by the JFK, the alarm syatem failed. If this hapen in subway it will still failed. Detecting the presence of a boat over a large area of water is very different than detecting 100+ pounds of what's basically saltwater entering a relatively small trench. A multitude of sensors could be employed, perhaps in congress to reduce false positives. A capacitance wire is very cheap and decades old and successfully detects the presence of a human in a space. Cameras, fitted with image analysis algorithms would require development, but could work. Use a system like the xbox kinect, and add some depth perception, and the system can know the Size and Shape of what's on the tracks. It would be pretty easy for a computer to distinguish human from rat. If they can incorperate infrared technology in it where the sensors can read body tempertures on the fly then it could work. The technology is definitely there. Infrared sensors that read body temperatures are prohibitavely expensive - and would be affected by temperature. In winter, coats would "dim" the humans, in summer, the track bed can certainly reach 98.6 degrees - which would render people invisible. The "Kinect" like depth perception system I described would use infrared, but as a light shone in a pulse pattern to measure the depth at a given pixel. (an Idea I had 7 years ago, never patented, and later appeared in the kinect, and yes I am still bitter about it :-| ) Link to comment Share on other sites More sharing options...

I guess the MTA concluded that for one thing though they see this option to be much less expensive then say platform doors or gates despite the high cost from the technology involved in the sensor system but that is an assumption on my part. Work Trains go through there as well as light trains from the Overhaul Shop,but hey what do i know... Oh I see. Because of the ease of access from ENY or Coney Island yard etc. as it is a direct part of the BMT system, but that's as a guess as a straphanger looking in.

officetrader Posted February 7, 2013 Share #43 Posted February 7, 2013 I understand that the firm that did the Korean subway made a proposal to do demo doors in NY subways to the NYCT and the MTA. They proposed to do it where there is no cost to the city or state……..WHY AREN"T WE LOOKING INTO THIS? All this takes is investigation and talks with that company. This is a no brainer to at least look into it. Its better than the button idea they suggest. Link to comment Share on other sites More sharing options...

realizm Posted June 25, 2013 Share #45 Posted June 25, 2013 Phote credits: NY1 News Newsflash: The MTA has established a definite, solid plan to implement track intrusion programs with the spinoff of this pilot program with the testing phases by the end of this year, according to a report from NY1 I've just found out this morning. . As of now, the number of accidents stands at 77 people , resulting in 29 deaths. As to where the program will start, has not been revealed as of yet. Perhaps we can discuss which stations would best benefit most from the installation of this new tentative program to be swiftly put into action and even speculate where the testing will start as again the details are still have not been released officially by the MTA apparently from the latest details published so far. The transit workers' union wants subway riders to stand back, and the Metropolitan Transportation Authority has put up safety warnings in stations and on trains. But Queens Councilman Peter Vallone, Jr. thinks track intrusion technology is the way to go if fewer people are to get smacked by subway trains. "This would alert the driver of the train to the fact that something is on those tracks and slow them down or stop that before someone gets hit or killed," Vallone said. The MTA plans to test suitable track intrusion programs by the end of the year, with the goal of cutting back on the number of people who come into the path of trains. So far this year, 77 people have been hit, resulting in 29 deaths. In 2012, 141 people were hit by trains, with 55 fatalities. Vallone believes the high-profile deaths of subway riders who were pushed off platforms, tried to run across tracks or chased smartphones onto the tracks show the need for such a system. "These last few incidents have really brought attention to the fact that there's something out there now that we can do about it," he said. "Let's take a look at it." The MTA says it's already on the case, having spoken to several vendors about track intrusion technologies.

Turbo19 Posted June 25, 2013 Share #46 Posted June 25, 2013 Well damn. Let's see if this test program is successful so that it could be implemented elsewhere in the system. Link to comment Share on other sites More sharing options...
itmaybeokay Posted June 25, 2013 Share #47 Posted June 25, 2013 I proposed something very similar when there was all the flurry about platform screen doors. I'm glad they're moving forward with a test. It's a much smarter, cheaper and easier idea then Platform Screen Doors, and it's also highly effective.

N4 Via Merrick Rd Posted June 26, 2013 Share #48 Posted June 26, 2013 Or what if the same alarm system was somehow integrated with the signal system and it could trigger them to put the red light if someone feel onto the tracks. Link to comment Share on other sites More sharing options...
