Effect anti icing nozzles

Hi,

In several towns in Japan i have seen anti icing nozzles in the road surfaces. Because i have never been in Japan during the winter (well ones but that was over 40 years ago) i have no idea how effective this system is. Can somebody tell me this?
Also i have looked at youtube for a video with these nozzles working but could not find this. Any suggestions where to find a video where you can see how it works?

I've seen it when my family went skiing at Yuzawa? onsen/ski town a long time ago.
Here is a recent summary report on road snow melting technologies. http://www.pwri.go.jp/jpn/seika/pdf/report-seika/2002-3-02.pdf

I have video of these in use at the JR Maibara station when I last went in March as our Hikari ride arrives. Funny how it was blue skies in Tokyo, get to Maibara and it's snowing and blue skies when I get to Kyoto/Osaka. I will upload to youtube soon (few days) and post again here when done....

Thanks for the responses so far.
John B, looking forward to your video's.

This is the video. http://youtu.be/sYalXnYaAA4 You can see the sprinklers work about 15 seconds in. It's not the best quality, so I apologize....

I've been told that in Nagoya they pump sea water onto the streets to prevent snow accumulation.

Hi John B,

Have you uploaded the correct video or provided the correct link? I see a train entering Maiburu and no nozzles.
