Video of the LEDline® 403 Freeway Installation Being Snowploughed During the Winter Storm of 16th December 2007
Please turn up the video volume controls, so that you can hear the sleet and snow hitting the windscreen and can gage how hard the snow / sleet was coming down. And, as you can see as LEDline® is installed below the pavement surface, snow ploughs do not toutch it so can not affect the LEDline®.
As can be seen from the pictures and video, up to 5 x snow ploughs sequentially clear and push the snow from the left hand lane to the right and then completely off the road. At the start of the gang snow plough section, the LEDline® can be seen going away into the distance and shows up to the right of the snow plough blades, with the second, third and forth plough's steel blade traveling directly on top of the LEDline®. (Note: each LEDline® section is placed 24m (79 ft.) apart). In the last segments, the fourth / fifth snow plough trucks are also seen traveling on top of the LEDline®, however, here the LEDline® is now showing to the left and rear of the trucks, so the LEDline® is clearly seen to the left of all the 5 trucks.
From a driver's point of view in an automobile, the LEDline® was easily seen and clearly visible up to 2 - 3 units ahead, and if you take the video shots from the bridge, the LEDline® was even more visible. Note: At this 403 site, a single unit of LEDline® is installed every 24m (80ft) for some 800m (2645ft) on either side of the road, so from the height of the bridge even with the low visibility conditions, one could still see some 5 - 6 lit units, which translates to some 120m+ (394ft.+) - 144m (472ft.), quite a distance in these sorts of weather conditions. And, yet these LEDline®units were only our 6 x LED nighttime systems, not the much more powerful, sunlight visible 12 x LED system.
The winter storm dumped some 25cm to 45cm (10" - 18") of snow and ice pellets, in temperatures at 06:00 of -4.4°C (24.08°F) and at 07:00 -3.7°C (25.34°F) with wind chill factors of -13°C to -12°C (8.6°F - 10.4°F), with a wind speed (at 06:00 and 07:00) of 37 km/h (23 mp/h).With the wind and blowing snow, there were severe driver visibility limitations and whiteouts.
The "whiteout" section of the video was taken the morning of the 16th December 2007 and gives some indication of how heavy the snow was falling. The rest of the video was also taken on the 16th December 2007 and shows the Ontario Rt. 403 LEDline® installation being gang plowed by up to 5 x snow ploughs. The video and pictures are not of a very good or of a sharp quality, but the weather was atrocious at the time, with heavy snow and ice / sleet and whiteouts.
Finally, although the road had been newly painted and had new in-pavement reflective markers, as expected, nothing of the painted lines or the new in-pavement reflective centerline markers are showing, since all are covered with snow. However the LEDline® is clearly visible as it is melting the snow and so shows up very well.
