Innovative Laser Crosswalk Concept

Innovative Laser Crosswalk Concept

Virtual Wall is an innovative device that makes it safer for pedestrians to cross the road by projecting laser images when the red traffic light is on.

Designed by Hanyoung Lee, the goal is to heighten driver and pedestrian awareness and to encourage both to follow the crosswalk rules.

    WOW, some future awareness technology! Amazing, tech leading our daily steps, scary isn’t it?

  2. Daniel Kurdoghlian

    I like the idea, but how is this going to work? I don’t think it can…

  3. Megan

    It will probably take a lot of electricity/energy to power this thing. Looks awesome though!

  4. Sara A.

    What if you need to make a right turn on red?

  5. Julie

    Without meaning to be all ‘look at me!’.. i almost got hit by two cars last week that both ran the same red light! So I think this would be a fantastic idea if it worked efficiently!

  6. Josh K.

    Responding to Sara A.
    I believe in some big cities like Manhattan, there is no turn on any red lights. Correct me if I’m wrong.

  7. Austin

    This is an awesome idea! I don’t know though… if putting a person in front of a moving car doesn’t make the drive put on the breaks, a large red laser wall might not either.

  8. john j

    right, so… how does it work, exactly?

  9. Pyramus

    John K.

    You can turn on red here in NYC.

    That might be a bit confusing if it were put here in Manhattan.

  10. Critical Eye

    This is just plain fantasy. Perhaps a neat prop for a sci-fi movie, but nothing more.

  11. some young guy

    If someone stops too far forward and looks out the window they are gonna get an eye full of laser….

  12. Final

    If someone is drink driving and sees this he will probably turn the car to avoid the laser and he might hit a pedestrian.

  13. Drew

    Lasers aren’t visible like that in air — unless the crosswalks are spewing smoke or steam to facilitate scattering. This thing will only destroy any visibility drivers once had, making an even bigger hazard for pedestrians.

  14. Jadi

    This idea also presents in Transmetropolitan comics (issue #20, page 15):

  15. Tangle

    I like the concept but can not see it being put into production…

    The sheer cost of it would be enough to prevent it being put into place! I can’t imagaine any city (well except maybe Dubai) being able to afford it – or it passing the beaurocracy.
    It seems to me that most council’s/local govenments like to stick to what they know and are reluctant to try new things.

  16. Jaqi Mugo

    Severely cool! The future is now.

  17. Hillie

    The idea of a wall in stead of a light is interesting. Great concept.

  18. Walter Langford

    We look for this several years ago, but could not find the technology. We put the in pavement lights at the stop bar. It has helped cut down on red light running and 40% reduction in right turn on red violations.

    We would like to hear from anyone that has developed this technology.

  19. Kron

    As pointed out, lasers are not visible in air as shown in the topic.

  20. Roland

    I imagine, how expensive this invention is and how exactly it should be set up…and how expensive will be the maintenance…:) I don’t think, that in nearest future these will be set up at all…but concept is awesome :)

  21. Kirvi Inci

    I like the idea, however improbable it might be. However, I think that it will not stop people from running the lights. Afterall if all it is, is a laser, people will still disregard it.

  22. Sam

    COOL! …..but no. it would be easier to just make a car that stops automatically or make a good train system

  23. KitsuneCC

    I do believe is kind of innovative, but it´s too much, maybe something smaller would do, you don´t need to actually put a wall to stop cars. Seems very expensive.

  24. Chris

    Like it was said before red lasers are not visible in air, green are but you would not be able to make pictures of people on the wall like in the pic.(A giant green wall might confuse people.)

  25. 2more

    What a pointless idea. Way too expensive and especially in these days where its all about energy effincy, this is quite dumb idea. how much more power do a bunch of lasers use compared to regular traffic lights? Dont know the number, would guess at least twice as much. Now count all the traffic lights in ur city and u know what that means. Whats the point anyways?

  26. Rambo

    the lasers are totally not real!

  27. Sam

    Makes me think of the Abbey Road album art! haha.

    And to Rambo: Of course they’re photoshopped. That’s why it’s a CONCEPT.

  28. Ryan

    @Pyramus: You cannot turn right on red in Manhattan!! It’s always an annoyance when I’m driving in the city. Actually it’s NYC-side, not just Manhattan.

    Clearly, this is a design idea, but lasers can be cheap (think: CD players). These would make the most sense in built-up urban areas, obviously.

    If I’m not mistaken, the Swedes do something similar to this in several aspects, but between opposing lanes of traffic. I believe they put up a more durable, permanent version of cling film from below to above eye level (haven’t seen pic). Apparently just this visual trick (you can still see across the lanes, but can also see an object you need to avoid) radically reduces accidents. I don’t recall the exact numbers, but they were exceedingly impressive.

  29. Glowing Face Man

    Whoah, this is really awesome

  30. MKQ

    You can’t turn right on red in Manhattan. Out of state drivers (or even out of city) have almost killed me on more than one occasion. I’m not saying it’s necessarily a good idea — but to all the naysayers – every day people get in little tin cans and fly — I’m pretty sure this could be figured out. What I would like to see is a redirecting of all those places where steam pours out of the street — then this would be a piece of cake (I’m not saying redirecting would be — but this would give the particles in the air that would help lasers by seen).

    I like making pedestrians safer…I just think it’s ugly.

  31. MKQ

    Oh…and if something new like this were to happen at stop lights — my hope is that they would be solar powered perhaps. That would also help if there were electrical grid failure.

  32. Mark

    This will never work. The one post IN THE ROAD won’t last a day in any major city. Not a chance.

  33. andrei

    funky. expensive. in extreme situations you won’t see the pedestrians you need to avoid

  34. Scott

    This is a dumb idea. The more technological aids we have for drivers, the less drivers will pay attention. We need less traffic controls, not more. this has been proven in experiments where all traffic control devices (signs, lights, road markers) are removed, accidents actually decrease because drivers are more careful.

  35. chris

    I like seeing innovative ideas that make the world safer for healthy living (walking). An alternative that is available now can be seen in downtown Houston along the lightrail. For a firsthand look, check out this video:

  36. Patrick Wells

    Umm, unless those laser things are shooting out STEAM or SMOKE to refract the beams, then this is physically IMPOSSIBLE.

    Physics 101 people.

  37. Karin Stewart

    Great concept! Let me know when the bugs are worked out!

  38. Karen

    i’m sure they’ll be only in certain places, and its not like its a working laser or something. It wont burn holes in your car if you drive through it, so yes, its ok to drive through it!

  39. Mickey Mouse

    Patrick Wells, I think you mean smoke or steam is required to difuse the beam not refract it.
    Any way it’s a dangerous idea, if sombody walks or drives throught it then they’ll get thier eyes burnt out. Hanyoung Lee will get taken to court.

  40. Critical Eye

    I’m surprised at how many people are missing the obvious flaw… light does not work as depicted in this comp! This concept CANNOT work! Heck, the PhotoShop work isn’t even any good!

  41. This boy needs therapy

    That will really help drunk drivers like to me to spot the red light from a distance and step on the brakes in time!Awesome

  42. FoxyBoxers

    HEY! hey. you are all spelling it wrong. its “LAZOOORRRRRRR”

  43. Julien Grimard

    Cool, but I think a lot of people are too stupid and would try looking directly at the laser and go blind! Or a car would go a little too far and the laser would get reflected everywhere, and once again people would go blind!

  44. Nitheen

    um, how come nobody has said anything about there being LASERS strong enough to cross two-four car lanes just pointing between two 8 foot tall bars? what about the hazard of some fool looking into the laser with his bifocals, or the automobile driver who drives through the thing and is temporarily disoriented….

  45. ShotgunEmmet

    Lasers are focused beams of light, always projected at the same rotation, flat against their target. Air is neither refractive or varied enough to display that light in all directions, so without the addition of some kind of gas i don’t believe the above picture is currently plausible.
    Also lasers can be made to be any colour, pulsating red would probably suit this one tho

  46. Yesiam

    john j asked:
    right, so… how does it work, exactly?

    Well john, if I remember right, the rules say: People are worth 10 points each, people in wheelchairs 5 points, old people with walkers are only 1 point (they’re easy to hit), Skateboarders, rollerbladers, and bikers are all worth 15 points, but drunks are worth 50 points, because they way they stumble all around the crosswalk makes them the most difficult to hit.(a car doesn’t have the same turning radius they do.)
    Up to four drivers can play at any one time at each intersection. So the guy squeezing betwenn your car and the curb isn’t going to score anything.
    Also, it’s forbidden to hit someone, then back up and try again for the next pedestrian.
    Finally, the winners score is also put up on the red way scoreboard for all to see. :o)

  47. Yesiam

    What about all the people behind the wheel that are stoned? They will just sit there admiring the cool light show and there’d be traffic tie-ups for hours!
    p.s. Yes Virginia, there is a Santa Claus, and people really do drive stoned.

  48. Mike

    It would be just like the fake owls that they stick up to scare pigeons away, they would work for a while, look cool – but after a while people would just ignore them and make a game out of it

    The cheapest way is to have fines that are so incredibly high, it makes them think about stopping and/or a hydraulic 1-2ft fence that comes out of the ground on a red light

  49. -dan z-

    I suspect installing poles at the side of the lane and the center of the road is VERY conducive to safety….

  50. Palscience

    I am sure this innovative technology would save thousands of people lives who die from accidents on traffic lights. Thanks for sharing the information.

  51. tim

    I’m fed up with all the product ‘concepts’ being added to SU. None of them are ever going to happen because they haven’t been properly designed. They are just some guy’s idea with an artists impression. They haven’t done any work to find out if it’s even physically possible to ever build it.

  52. Hussam

    Great work…
