My favorite kind of traffic jam is when a moron cop decides to pull somebody over on the shoulder during rush hour. The resulting miles long back up, the slamming on of brakes and the ensuing traffic accidents caused by this hero of the people keeping us safe is pathetic....

Wait for it...

Wait for it...

You know you want to defend the cop and blame it on the speeder.

Oh, and all you rubber neckers who have apparently never seen flashing lights on top of car, quit looking, smash the long pedal on the right and move on out. You sheeple don’t need to look! Same goes for accidents on THE OTHER SIDE OF THE HIGHWAY slowing down opposite and otherwise unaffected traffic.

Other than the neat graphics, there’s nothing new there. Civil engineering textbooks had the same information 40 years ago.

A yellow light on the rear of vehicles, to alert drivers when a car is coasting, would reduce traffic jams caused by rubber necking and similar phenomenon.

I moved to a small Midwest city ( South Bend IN ) about three years ago ( from Chicago and before that St. Louis ) and one thing I really love is not dealing with traffic. A traffic jam here last about 5 minutes. I remember marathon jams in Chicago that folks around here could never fathom. I got in a traffic jam once when I was literally 2 blocks from home and an hour and a half later made it home! The worst jam I was ever in was about 4 hours. Don’t miss that crap for a second.

People are idiots behind the wheel sometimes. I had a guy in front of me come to a FULL STOP on a freeway on-ramp, just so he could watch some other guy change a tire (for all you Bay Area Freepers, this was EB 92 to SB 101 in San Mateo). Just think if he had done that after merging onto the freeway?

A first cousin of mine is a civil engineer with the NCDOT. I’ve spoken with him several times about highway design, traffic flow, etcetera. It’s actually pretty interesting, not dry and dull as it might sound initially.

Terminology that jumps out in memory would be “friction,” which refers to widely varying speeds among vehicles on multilane highways traveling in the same direction. “Friction” is bad and leads to accidents. Passing on the right is bad “friction” because it’s either unanticipated or because it puts higher speed vehicles beside merging vehicles, increasing the variation in speed and hence not just the liklihood of an accident but the severity of it.

Highest speed vehicles should always be in the lane furthest removed from lowest speed merging traffic. This explains the laws in many states requiring slower vehicles to move right for overtaking vehicles, regardless of speed. It’s safer to let Mr. Speed Demon blow past on the left for all involved. Don’t play rolling roadblock because you’re doing the speed limit, it might cost somebody else more dearly than you realize.

Another term is “slinky effect.” Ever gotten stuck in a traffic jam in the middle of nowhere, for no apparent reason that appears to break up for a short distance and then reform? Or, the typical stop and go of heavy commuter traffic, both the same thing. Disruption of the flow, whether due to an accident or traffic beyond design capacity clogging interchanges, reduces the throughput of the highway. Stoppages radiate back from the initial site, sort of like echoes and they’ll reverberate on a heavily traveled road for hours. Move, stop, move, stop. Slinky.

I have theory that there is a constant traffic jam on the Beltway around Washington DC. 24-7. It never dissipates - it simply moves around the Beltway as the cars in front get going and new ones get caught in the jam back behind.

I have commuted on NYC roads for years. I know all the idiots. What most of you describe are drivers with the “me first” syndrome. The ones who you are doing 70 and they must pass you slide to the left lane and then do 55 60 (they also have trouble holding speed). When you try to pass they will speed up to 80 to make sure you can’t get around them. (Me first) Then back to 55-60. I found drive smaller engine cars the way to defeat this is to accelerate before moving over to pass. Once you move over you have momentum and it is too late for the “me firsters”. Then I like to heavily clean my windshield and the overspray washes over their cars. This is called washing them. The best” me firster” was driving an older model Cadillac. He got so mad I passed him in my VW he was giving me the finger and squinting to try and figure what I was doing to my windshield. When the washer fluid soaked his hand boy was he pissed. I laughed all the way home.
Another thing I hate is the brain dead people that drive on the Highway with the brights on. They come up behind you and you get blinded until you can lose them. They never seem to pass just hang out and blind you. This calls for the rear defense shield. You need an unlit passenger mirror. The bigger the better. You can flip it down and Watch your headliner to reflect the brights right back at them. It works over 75% of the time. You could do it with your rear view or side mirrors but then you have to readjust them.

So the "author" KNEW that this would be excerpted?

Interesting.

Pretty good book and website about the same subject.

Always seeking to be on the frontline of stupidity, Massachusetts has added to routine traffic woes by the use of (I’m sure very expensive) electronic traffic signs with brilliant messages like, “Click it or ticket” (seat belt warning). Drivers instinctively slow down to read them and ‘whammo’, instant traffic jam.
