Lane Departure Warning System

[Reba]

it's here in NY, NJ, CT, MA, VA, MD, PA, and WV.

How do they avoid damage from the plows? Are they recessed some how?

I remember when blue lane reflectors used to be for sunbelt highways only until they began to recess them.

eh? no it's because it's to prevent sleepy drivers from getting in bad accidents.

He means that some states don't have the rough strips is because they aren't compatible with snow plow blades.

That's right. Thanks.

I suppose there are few procedures -

1. stay in middle of the highway and their plows are wide enough. The plowers (DPW) most likely know these roads like back of their hands.
2. lift the plow 1" higher
3. the routes were preplanned and prepared in advanced and the certain obstacles were probably recorded in their log/GPS or used reflectors as a signal to lift the plow as you said

whenever we have snowstorm, NYC is the worst. Tons tons tons tons of snowplow damage. The holes can be gaping huge!

That's right. Thanks.

just pointing out that it's not limited to southwest only or rare snow.

Ah, that's the real answer. The plowers just don't care about the damage they cause!

Rumble Strips

Rumble strips are a grooved pattern in the pavement that make road travel safer for motorized vehicles. The grooves alert drivers by causing the vehicle’s wheels to noisily and suddenly vibrate when it leaves the driving lane.

This article deals with both edgeline and centerline rumble strips as well as the construction inspection guidelines that must be considered to achieve a high-quality product. Guidance is also presented for transverse rumble strips, warning devices placed in the driving lane.

Surface-mount raised pavement reflectors are easily removed by the blade on snowplows and thus are not practical in many locations in the United States and Canada.

yep... I think the city knows this and there's really no choice. They do repair the holes few days after the blizzard. They just started fixing it 2 days ago along West Side Highway.

That's what I thought. No wonder NYC is most expensive in USA.

That's what I thought. No wonder NYC is most expensive tax in USA.

Connecticut is considered the highest tax state in USA. I believe NY is around 5th-10th.

Most highways at IL have rumble strip like that.

there you go. it's not limited to southwestern states.

I was thinking "rough edges" of that.

The snow plow wil damage it.

ah... I see but... look at Vampy's post

A lot of highways already have those rough edges on the shoulders that will really rattle you if you ever go over the shoulder.

That's a enough clue to know what he's talking about but it's ok. You get it now - the Rumble Strip. I never knew it was called Rumble Strip either.

in Seattle area has lot of those on the shoulders of the roads and on the lane dividers, etc. Also, there's some huge ones that are called "turtles" which can whack your car real good if you accidently drive over it. I think there are snow plows with rubber strip on the bottom to prevent damaging them. Of Course, California has it almost everywhere except in the mountain regions.

I forget which state AZ or NV or TX or CA that they do have "bump" at the shoulder too. No need to reread vamp's post.

huge snowplowers in here do not use rubber tips especially for highway. It's razor-sharp metal. I believe Mythbuster did an experiment on it that snowplower can cut the disabled car in half :Ohno: I think it was found plausible.

Oh yeah. Most snow plow with rubber strip from IL/IA and still damaged the road.

pretty much all states do. It's called road reflectors. or reflective road stud. or reflective pavement markers. Reflector's just easier to say it.

Some uses just simple reflective painted stripes to save money especially for long long long highway.

 

[The Highlander]

Happen at Chicago before. It's awful slow and heavy traffic.

wow great pix, Highlander.
