No matter what the speed limit is or what the reason for it, having split limits is more dangerous than having one limit..

 

IF there was some stretch of road ANYWHERE , where people actually did the speed limits. The whole point is basically worthless and better yet unprovable because there is no way to get real data. There is no real proof anywhere other than someone's pet theory that this split speeds are dangerous. Name the road where the data was taken that proves the myth...

 

Do you remember when the speed limit was 55 in most places? As you can see that was too slow for the 4-wheelin' motoring public, so the politicians changed it. Politicians in 55 mph states like the revenue they get from 55+ mph trucks. Life is less stressful in these states if you just set the cruise at 55 and let everyone else go around.

 

Sounds like senoir Fozzy doesn't even drive a truck ...probably rides a vespa .

 

common sense would tell it's true if you had any

 

He just likes to argue, it probably keeps his mind off his other problems

 

I go through Illinois a lot and I set the cruise at about 57, trucks go around me constantly. even JB and Swift. those guys seem to think that if your truck is governed at a certain speed, then you MUST go that speed at all times.

 

“In 1963, David Solomon reported that deviation from the mean speed of traffic in both the negative and positive direction contributed significantly to the occurrence of accidents. In fact, Solomon showed that vehicles traveling 10 to 15 mph slower than the mean speed of traffic were much more likely to be involved in accidents than vehicles traveling slightly above the mean speed. Solomon presented his results in the now famous ‘U-shaped’ curve, which relates variance from mean speed to involvement in accidents.

“Solomon’s study was conducted on two- and four-lane main rural highways. A similar analysis was conducted on the interstate that has higher operating speeds. The data for this study was collected by 20 state highway departments, including Ohio. The analysis showed the same ‘U-shaped’ curve for interstate highways and generally lower accident involvement rates, again confirming the safety benefits of the interstate system. The analysis also showed the variance in speeds on the interstate was between 5 to 7 mph, approximately half that of non-interstate facilities.

“The National Highway Traffic Safety Administration subsequently contracted with Indiana University to conduct a speed-safety study. This study confirmed the ‘U-shaped’ curve established by Solomon and the interstate study.”

Ohio truckdriver and OOIDA member Dick Chambers told the committee, “By raising the limits on the major interstate systems, the state would give truckdrivers a greater incentive to drive on the safest roads in Ohio. Our interstate highways have limited access, are wider, have banked curves and, as many of you know, were designed for speeds in excess of 65 mph.”

ok Fozzy, go ahead and tell me why this study isnt legitimate

 

and this one
Attention: Illinois truckers. Another attempt is being made to end split speed limits on the state's interstate highways. Take time now to contact your state legislators and speak in favor of uniform speed limits.

Rep. Robert Flider, D-Decatur, and Sen. John Sullivan, D-Rushville, have taken up the battle to eliminate the provisions that set up slower speed limits on rural interstates for vehicles weighing more than 8,000 pounds. Currently, those vehicles are required to travel 10 mph below the 65 mph speed limit.

Flider's bill - HB1786 - and Sullivan's bill - SB540 - would allow the Illinois Department of Transportation to increase large truck speeds to as much as 65 mph.

Flider made it clear that even if the bill is signed into law it doesn't guarantee elimination of the speed gap. The bill allows the state to consider authorizing uniform speeds. Its passage wouldn't mandate a change, but it would allow for a change that is currently not an option.

Gov. Rod Blagojevich has said that he fears faster trucks would mean bloodier accidents because the force of impact is stronger the faster a vehicle is traveling.

But federal statistics show that split speed limits actually lead to more accidents. Flider cited these concerns as reasoning for introducing the bill. Studies show that uniform speed limits would actually be safer.

Fredog, nice job finding that proof there. Very helpful articles. They very much enforce my point in this topic, if you look back to my first post. Thank you Fredog.
