Title: Speed limits
Post by: Chris on January 23, 2009, 04:48:30 PM
I always wondered why many eastern U.S. states have such slow speed limits. In Europe, most countries have a maximum speed limit of 75 / 80 mph on their freeways, unless posted otherwise (mostly 60 - 65 mph in denser urban areas).

I always notice those 65 MPH signs in rural areas of many states, like Illinois or Oregon, I would almost fall asleep with such crawling speeds... Is there a specific reason for it?

Especially suburban areas of U.S. metropolitan areas almost look like rural areas due to the absence of houses or buildings next to the roadway.

In contrary, truck limits in Europe seems to be lower than in the U.S., most trucks are limited to 50 / 55 MPH in Europe on freeways.

In the 1980's the speed limits were limited to 55 in every part of the state of California. That did not last. The speed limits are 70 in some places, but 65 for the most part. Not very many people go that slow, though.

some of it has to do with the national 55mph speed limit of 1973 (to conserve gasoline), but even before then, some US states were rather slow.  For example, I think it's still on the books that, unless otherwise posted, Massachusetts's speed limit is 40 mph.

how well are speed limits enforced in Europe?  Here, it's a total guessing game.  For example, the central valley of California is posted at 70, and nobody does under 80.

There's no real reason, especially on wide open roads that were made for speeds of at least 70 mph. In Atlanta, every freeway within I-285 is posted at 55 mph. This is how I see posting speeds, at least in Atlanta.

Downtown Connector (I-75/85): 60 mph, because of all of the traffic.
I-285: 65 mph. 55 mph is too slow. I can travel at 70 to 75 easily. Speeds are usually in excess of 85.
SR 166 (Langford Parkway): 60, maybe. 60s-era design is dangerous, so 55 may be appropriate.
I-20 (between I-285 -Westside and I-285 - Eastside): 65 mph. I-20 between I-75/85 and SR 280 is posted at 50, the lowest speed limit on a freeway inside of I-285.
I-85 South Southside (between SR 166 and the Union City city limit): 65 mph. Speed drops to 55 mph for no real reason, coming northbound on I-85.
I-75 North (between Downtown Connector and I-285): 65 mph. No reason to have a cap of 55 mph.


Politicians seem to cap speeds because of smog. I think that's foolishness, personally.

It depends from country to country. The chances of getting a fine on the freeway in Europe isn't that big. 40% of the German freeways (Autobahn) have no speed limits at all, so sometimes people fly by at 120+ mph, though most people do not exceed 100 mph.

I usually drive between 75 and 80 mph. I do care about my gas mileage due to our insane fuel prices :)
I actually have never gotten a ticket on the freeway in any country in Europe.

there are speed cameras everywhere in Norway, but then again I didn't go on the freeways.  Just little rural roads with speed limits 80 or 90 km/h.  Other people blew right through the camera traps; I have no idea how people know which ones are working and which ones are not.
Title: Re: Speed limits

Norway's fines are incredibly high I heard, and speed limits are only 55 mph on freeways too... In Finland, they calculate your fine on your income, so if you earn 50 k pear year, your fine is considerably higher than when you earn 20 - 30 k per year.

In NL some roads have section-control, especially on 80 km/h (50 mph) zones. That means a fine garantueed when speeding.
Although speed limits are 100 km/h (62 mph) and 120 km/h (75 mph), I mostly drive at 130-140 km/h (80-88 mph).
No speeding tickets received until now - let's keep it that way...  :cool:

Politics.  That's why they speed limits vary so much from state to state.
Title: Re: Speed limits
Post by: vdeane on January 23, 2009, 08:38:54 PM
I think truck/night limits may have something to do with it.  When Texas raised the speed limit on some roads to 80 mph and some photos were posted I noticed that they had separate speed limits for cars, trucks, and at night.  Here in the northeast we don't have that.  Everyone obeys the same speed limit no matter what vehicle they drive and what time of the day it is, so the speed limits are set for tractor trailers driving at night.

Politics also plays a part.  When many of the roads were raised to 65 mph in NY ten years ago, some of the areas where the speed was raised were clearly raised only so politicians could get re-elected (I-390 in Henrietta and I-81 in Syracuse come to mind).

Nevada state highway 140 - I don't think the highway patrol even knows it exists!

Was checking that one out (and Oregon 140) on StreetView a few weeks ago.  Looks like a very fun stretch of highway, and one of these days I'll get out there.

As far as Oregon's speed limits go, they are indeed pathetically low, much to my extreme annoyance.  There have been several bills since the full repeal of the NMSL in 1995 to raise the speed limit.  The initial ones would have raised it to 75mph (what Oregon's limit was before the NMSL), and they all passed the House and Senate with flying colors only to get vetoed by then-Governor Kitzhaber every time.

Technically, a bill did become law a couple years ago to allow 70mph speed limits on Interstates, but it left it to ODOT's discretion rather than mandating that 70 zones be posted.  Hence, it's still stuck at 65, though, because ODOT and the trucking industry were at odds as to whether the truck speed limit should be 60 or 65 in the 70 zones. 

The Interstate thing is not the most pathetic thing, either--it's the fact that all non-Interstates are still stuck at 55mph.  Even the stretches of US 20, 97, 95, etc. that are way out in the middle of the desert, and really ought to be 65 or 70 zones.  (One of the 75mph bills in the 90s had a provision to raise the non-Interstate maximum to 70.)  

The one thing Oregon gets right, though, is getting rid of the word "limit" on speed limit signs.  Makes it far easier to read the number, I find.

Here once you leave the heavily developed portions, around Hampton Roads Center Pkwy (I-64 Exit 261), the speed limit increases from 55 to 60, and then once you leave the improved section of 64, at VA-143 (Jefferson Ave. - Exit 255) the speed limit increases to 65. That's the speed on every stretch of interstate in VA that I can find except for I-95 and I believe I-85 both south of Richmond. But the average speed everyone drives around here, even in the 55 zones, is only about 85, which is much slower than what I've observed elsewhere.

As for raising non-interstate speed limits, we have a few other roads around here that are 55, including Hpt. Rds. Ctr. Pkwy., Victory Blvd. (VA-171 - Notable as it's a 2-lane road), Magruder Blvd./Hampton Hwy. (VA-134), and then a few farther out in the rural areas like US-17 (Geo. Washington Mem. Hwy.), but with one of them being a 2-lane road and the others 4-lanes with heavy traffic at almost all times, I really don't think a higher speed limit would even be very effective. Seems a little bit unnecessary.

When the Arab oil embargo occured by in the early 1970's. President Nixon imposed a national 50mph speed limit.  In a short time, it was raised to 55mph which became the national standard for years to come. The only reason why speed limits are not higher is because of the significant income earned by localities from speeding tickets.  In reality, traffic does flow much faster than indicated by the limits.

All of Interstate 95 in Delaware is signed with a 55 mph speed limit. Its almost impossible to find one driver do the 55 mph speed limit during free-flowing traffic conditions. When Interstate 495 was granted 65 mph status, an agreement was made that all signage would include "Strictly Enforced" placards. That was the caveat given to those opposed to the increase. The Delaware 1 turnpike also has a 65 mph speed limit.

In West Texas,  both I-10 from El Paso to Kerrville and I-20 from its split from I-10 to Monahans, have a speed limit of 80 mph, although trucks have to keep it at 70 mph. That nighttime speed limit of 65 is still in effect as well.

IMO, all modern highways should have a speed limit of 130km/h.  Older ones with less safety features could still go as high as 110km/h.

Arkansas is 55 on 2-Lanes, 60 (occasionally 65) on divided 4Lanes, 70 on Interstates (except metropolitan areas which are 60-65)
Title: Re: Speed limits
Post by: agentsteel53 on January 24, 2009, 03:35:47 PM
Texas has a county-by-county rule that allows for a maximum speed limit of 65, 70, or 75, depending on the county's population density, if the road is considered "rural".  this leads to some quite grand speed limits, like 75 on US-285 (a two-lane road in the middle of nowhere) and 70mph on US-290 coming into Austin (an undivided four-lane expressway with driveways and cross streets at grade, and more deer than you can shake a Winchester at).

80mph is just an added bonus by the legislature that allows the 75mph counties to be 80 on the interstates.  Good times.

The one thing Oregon gets right, though, is getting rid of the word "limit" on speed limit signs.  Makes it far easier to read the number, I find.

Except that they're vioating the MUTCD by doing that, and I do believe AASHTO has gotten on their case about it more than once.

Besides, how hard is it really to read the numbers on a standard sign? It's easy, unless the sign is poorly placed in a spot where it's not very visible.

Personally, I think speed limits in general are silly. It's way too much of an oversimplification of the matter to just have one number. One size does not fit all. How fast it's safe to be driving varies not only from road to road, but from vehicle to vehicle, and from driver to driver (as wel as with the weather).

As a spry young 21 year old with quick reflexes and the ability to slam the brake real hard, I can safely drive considerably faster than a weak old lady who's slow to notice, slow to react, and can't slam pedals with such force.

For engineering calculations, it's standard to assume that it takes 2 seconds - yes, two full seconds - for a driver to react to an obstacle after seeing it. Obviously, most people can react much faster than that, but with engineering you have to be conservative about it.
So, in essence, the speed limits are calculated based on grandpas driving. Unless you're old like that, you can be driving significantly above the speed limit and still be driving safely.

Given that, I tend to simply disregard speed limits and use my own discretion and judgment as to what's prudent instead. I know what me and my car are capable of better than any sign does.

That's why when you took a Driver Education class to get your license they told you that that is the speed limit in "ideal conditions" and that it is advisable to drive slower in traffic, if you're nervous or having car trouble, or in inclement weather.  ;-)

Actually, Oregon has an approved supplement to the MUTCD that allows the word "Limit" to be dropped, though I believe the FHWA gave them a hard time, which is why you see the occasional "Speed Limit" sign on I-5 and I-84.  They apparently thought that people would think it was "just an advisory", which is kind of silly reasoning. 

Personally, I'd prefer to see the Oregon-style setup phased in as the MUTCD standard, but I'm biased. :D 

And I do think we should go to an advisory-only setup in most situations.  Montana had the right idea, I think. ;)

Montana definitely had the right idea.  I don't think speeding should be a crime.  Driving too fast for conditions, sure.  Reckless driving, absolutely.  But just exceeding a single fixed number that does not take into account road conditions - not so much. 

45 in a 25 in a neighborhood with small children?  Sure, that's bad.  But out in the middle of nowhere, say I-10 in west Texas, whether one goes 75 or 90 or 110 usually doesn't make a bit of difference.

Wyoming is one of my favorite highways for speed limits. Any narrow-shoulderless cowpath with a Wyoming Highway shield gets a speed limit of 65 in a rural area without any regard to how well the roadway is built. There are dozens of places within the state where the road is barely two lanes wide due to how overgrown the edges are but the speed limits are still 65

I thought this was very odd when I came across it in Gloucester Co., VA the other day. Never seen a sign like it, and there were ones at higher speeds too, where the road was even better maintained after the sign, so I assumed that instead of defaulting to 25 (state speed limit unless otherwise posted) there was actually NO speed limit, and thus went 55  :sombrero: where the road could handle it, anyway. Oh, and apologies for the poor picture quality. I don't have a camera, so took that on my phone.

We've got those all over the place in Oregon, actually.  Legally, it means that the speed limit reverts to the statutory limit for the type of road.  They've largely fallen out of favor with ODOT, but they're still fairly common on county roads.  And at least as far as county roads go out here, they're not likely to be enforced.  I'd imagine the FHWA and AASHTO have a collective heart attack anytime they see one.

- I-95 through New Hampshire, the 12 miles or so from the southern end of Portsmouth to the MA border is 65 mph but it has 4 lanes in each direction, no hills, and it perfectly straight for the most part.  But it's also enforced pretty well, although people still fly on it.  Continues down through Massachusetts to 128.  Straight, flat... 65.

- Besides the Portland and Bangor areas, the interstates in Maine are 65 mph, which is dumb when you head north of Bangor because that road also straightens out and in the 120 miles between Bangor and Houlton, you'll see between 10 and 20 cars.

- The high-level Piscataqua River bridge that takes I-95 from New Hampshire to Maine is always an interesting place to drive.  Just about every day I cross that bridge (Portsmouth and the first three exits in Maine are 55 mph)... I go 65 through the area, and as I'm going up the bridge everyone else is going 50-60 and I'm passing them.  Starting back down the bridge into Maine everyone's passing me going between 65-80.  That's just a case of people being afraid of the Big Bad Bridge.  Of which it's not.

- Finally, the US 1 Bypass which is the second of three ways to go from Maine to New Hampshire, has a 35 mph speed limit on the stretch in Kittery approaching the bridge to Portsmouth.  The road has 4 lanes with a center turning lane and very little traffic, and only a few small businesses.  It is straight and flat.  35 mph.  My biggest speed limit gripe.  Great place for the police to sit too.

Really? Hmm... that must mean it goes down to 25... (I think) Which is, well, retarded, as the roads in question could easily handle 45 without even slowing down for the curves. They had a double yellow centerline, paved shoulders, guardrails, etc. And for the record, I didn't see a single cop.  :-D

Actually, they're technically 55 here after the "End XX Mile Speed Zone" in most situations here in Oregon.  They're almost always at edges of towns in rural areas.  I believe the wording in the Oregon Drivers' Manual basically states that they're technically 55, but 55 may not be appropriate for them in all situations.

55mph is the statutory speed limit for pretty much everything aside from residential zones and interstates, 25mph is statutory for residential zones (and beaches), 20mph for CBDs and 15mph in alleys.  Everything aside from that is the result of an overriding "Speed Zone Order", which is produced after ODOT does a study and consults with local jurisdictions. 

Of course, there has been some rather interesting abuse of that system, because it can be a matter of splitting hairs as to whether a road is "residential" or not.  The override orders are actually posted online (https://keiko36.odot.state.or.us/whalecomfb751917efb5683a9c287df8a9ad831f7e55a2048a/whalecom0/cf/szi/), too (a major time-waster for me), and I've found quite a few situations where it appears local authorities have illegally lowered speed limits. 

I've been considering outing them on my (currently unused) blog. :sombrero:  Washington County and the cities within it are particularly guilty.

Well according to my Driver's Ed class I took and my VA Driving Manual, 25's the statutory speed limit here in VA except on interstates which are 55. Regardless of what type of zoning, etc., it's all just 25... which really doesn't make sense and there must be some exception it doesn't mention.

As for ODOT's speed limit system, I wish VA did something similar... that would be really helpful.

Quote from: TarkusOf course, there has been some rather interesting abuse of that system, because it can be a matter of splitting hairs as to whether a road is "residential" or not.
Heh... I believe that. Politicians just use it to advance their own personal interests I'm sure.

And you have a blog?  :-P

I've been considering outing them on my (currently unused) blog. :sombrero:  Washington County and the cities within it are particularly guilty.

Here in SC, our statutory limits are 30 (urban) and 55 (rural), although SCDOT does a poor job of posting them at the state line. It appears that North Carolina's are 55 and 35 - if you cross the state line on any road other than an interstate, there are signs that read "State speed limit 55 unless otherwise posted," and I also see many city limit signs with "Citywide speed limit 35 unless otherwise posted." The "citywide" signs are frequently posted on roads with higher speed limits, so I assume it's the standard sign for NC.

LOL . . . I may just have to.  I started the blog awhile ago, but thus far, haven't posted anything to it.

Quotefrom deathtopumpkins: That's the speed on every stretch of interstate in VA that I can find except for I-95 and I believe I-85 both south of Richmond. But the average speed everyone drives around here, even in the 55 zones, is only about 85, which is much slower than what I've observed elsewhere.
Its 65 throughout Virginia in the rural areas(except for maybe I-85(as it might have been raised to 70 in some spots(I am not sure though)).  In the Richmond/Tri-Cities area I-295 is 65 throughout, I-85 is at least 65 up to US 1/US 460 Bus(Exit 63) and 60 up to I-95, which is 55 in Downtown Richmond and Downtown Petersburg but 60 from Colonial Hieghts to 1/2 mile south of Maury St(Exit 73).  For other freeways, VA 288-65 throughout, VA 150-60 from US 60 to I-95/VA 895(the rest of the freeway is 55), VA 895-60 west of the toll plaza, 65 east of it, and I-64 is 65 up to VA 288,  then 60 up to at least Gaskins Rd or US 250/Broad St and Glenside Dr,  55 in Downtown Richmond,  60 from US 360 to about VA 156/Airport Dr and 65 east of there until Hampton Roads.

It's kind of funny, in the Detroit area, the Southfield freeway (M-39) is listed as 55 Mph, but the normal speed people do is 70! Even more hilarious, on MDOT's site, in their traffic conditions page, they report the average speed as 65.

It's even worse in Indiana, where on I-465 people do 70 in a normal 55, but at the time it is a workless work zone posted at 45.  Real fun for the out-of-state driver, especially when there are multiple cops about, but who don't seem to be enforcing the limit.

How far north does the speed limit stay 70?

Hopefully soon portions of I-81, I-77, I-64, I-66, and I-95 along with VA 288 and VA 895 will also be allowed to be 70.  I would even throw in VA 168 south of VA 190/Kempsville Rd until the toll plaza.

The reason is revenue enhancement.

80 is reasonable.  They know most people will just go 80 anyway, but the 65 limit means they can legally get you for doing a perfectly safe, reasonable speed.  This, of course, translates to lots of money coming in from ticket revenue.  Speed enforcement wouldn't be the profit machine it is if speed limits were posted at what were actually reasonable.

Additionally, we've become so conditioned to it, thanks to the propaganda machine, that we tend to think raising the limits to 80 would cause everyone to drive 95, when in fact it wouldn't.  Most people are comfortable between 70 and 85, the rest are either those who will obey the speed limit right on the nose or those who will not drive reasonably no matter what.

The speed limit on I-85, from SR 74 to the end of the I-85 reconstruction zone in Fulton and Coweta counties (GA), has been lowered from 60 m.p.h. to 50 m.p.h. There have been three-to-four major accidents in this area. This construction should be finished in late December '09.


Be well,

Bryant

US-43|72, you hit it on the head. Most people find a comfort zone in the low 70s. Take away any speed limit, that's about the average speed people will travel.

It is a money-making venture by states, and until that little issue is corrected, speed limits will ALWAYS be artificially low.

TxDOT is temporarily dropping the speed limit on I-30 through Greenville from 70 to 60 between M/M 91 and 96 due to the upcoming reconstruction of the TX 34 interchange (Exits 93AB); construction of the new Monty Stratton Parkway interchange (future Exit 92); the addition of a turnaround bridge at Bus US 69 (Exit 94A); and the realignment of the westbound frontage road at US 69/380 (Exit 94A).

This is all in addition to converting the frontage roads along I-30 between Monty Stratton Parkway (future Exit 92) and Division St (Exit 95) from two-way to one way.

The completion date for all of this is sometime in 2011.

Bringing this old thread back, the Texas House approved a bill yesterday that would allow for a speed limit up to 85 MPH (http://www.chron.com/disp/story.mpl/ap/tx/7511083.html).

All of Interstate 95 in Delaware is signed with a 55 mph speed limit. Its almost impossible to find one driver do the 55 mph speed limit during free-flowing traffic conditions.

And because of the flow of traffic around 70-75 mph, my wife will not drive that road unless she absolutely has to.

What is with Vermont, Delaware, and New Jersey all having two lane roads at only 50 mph?  Also, Connecticut has US 7 posted at a maximum limit of only 40!  A few miles west across the state line NY Route 22 is 55 mph.

Then Arkansas has only 55 mph on two lane roads while Oklahoma lets you do 65.  No wonder why I-49 is needed! I drove US 71 from Kansas City to Lafayette, LA and it took me all day!  That 55 was too slow for that type of highway.
