A simple way for cities to increase the flow of traffic, help eliminate gridlock and at the same time make cars more fuel efficient.

This only works if the driver is going the correct speed limit & paying attention (not texting or talking on cell phone)

Well, Grumpycat, we don't live in a perfect world, do we?

Occasionally (such as on curves and hills) there is an enlightened highway department that posts "Signal Ahead." Sometimes they even notify you if it's going red!

We have a parkway with a sign on a signal post, "Signals Are Timed To Deter Speeding." A graffitist changed it, "...Timed To Annoy You."

Then they wouldn't be called "stop" lights if their purpose was NOT to stop and hinder traffic.

Traffic lights *should* be networked. You *should* have an electronic transponder "license plate". Traffic lights *should* dynamically adjust to traffic demands. An indicator should be provided to drivers of advance notice for up coming traffic lights along with a hint, "If you drive X MPH then we'll make the lights change for you."

But all that is way too much for the 6th grade education of bureaucrats who run the government.

In Hamilton,Ontario you can go the entire length of the city without catching a light if you drive at 52kph. That's about 31mpg for our American friends. Speeding doesn't help but consistency does! A busy time of day with more cars on the road might mean you'll actually get 1 or 2 lights for the entire ride.

Did you know that if you drive the same roads every day, and have to go through the same lights every day, you can actually figure out how to get it timed to catch all, or most green. Running like a rabbit from light to light will not get it though.

This is right, but here in Lexington, Kentucky we have the poorest timed lights in the country. Some of the lights you can literally eat your lunch while you wait for them to change.

Amen, dontuknowOH!

Those jack-rabbit habits are not only unsafe, but inefficient! Just watch people who maneuver, even swerve, between lanes as they jockey for position. Chances are you'll be within a car length or two of them at the next red light. Pay attention, you'll see--all that aggravation (and risk) is most always to no advantage.

I hit mandatory retirement this year, and am now driving taxi part-time. Now I could run red lights, and probably get off by flashing my "Retired P.O." badge if pulled over.

But it's not right, and I make good money driving in a relaxed manner.

Guess I'm turning into an old fogey!

Its pretty much normal for vehicles to bunch-up when stopping at lights,bunching close hitting the yellows is common,but 5 over allowed often becomes 10 over not by idiots but drivers that have a hurry attitude,resulting in the phrase "I speed up on yellows to clear the intersection"/if the yellow catches me,or I was glancng to my left mirror for a second....Really!...

A hurried attitude driver uses normally more fuel,that pace is hard to change,others have made saving fuel a goal,some still don't know what they do wrong,or don't do to conserve,often I think back to when fuel was $.95 a gal.my habits have improved since. HABetterD....

dontyouknowOH, you put a lot of thought into that post. To tell you the truth, I'm not sure I followed it.

But if I may add: the human element almost always confounds the most diligent of social engineers.* One is drivers in cross-traffic jumping their green. The other is people on the primary road running yellows and reds.

Then there is the frustration of "the slinky effect:" You're several cars back, and it just takes several seconds for the cars ahead of you to get going and spread out. When they stop, of course, they compress.

*Ever notice most social engineering comes from the political left-of-center?

Agreed. Where I live, they have personnel constantly monitoring the intersections and making changes in the timing to make the flow of traffic more efficient. I would like to see this happen in other places.

This was done around here (SW Cleveland, OH) about 10 years ago.

Now all the road sensors are breaking and the lights revert to "automatic mode" making them ineffective.

If working properly, the light should allow you to get from one end of the city to the other without ever stopping more than once or twice (more if you cross a main artery that has a different light sync than your street).

Often traffic is flowing 5 above the limits where control lights are set to the minimum on the yellow span,then often the vehicles going 5 + over and faster will clip into the red,partially,wholly,or after enter that red span(nearly under).

The cross flow is held often 2 seconds longer red before going green,if no jump starts fine,but the worry is resuming traffic already in motion,that pass the jump starters > > Bang... is often the results

When the yellows get longer saconds local traffic going 5 over the limit quickly learn the longer yellows and try for the jump threw growing to three vehicles at a time on longer yellows > > Bang again....

Then holdeng the cross flow red seconds longer helps the bang-ups a little but traffic back-ups occure slowing the flow,causing some jams/rear-enders.

I thing more stricter control of the 5 over during heavy T.. flow hours along with reasonable yellows/delayed reds would smooth out things,there will always be an Idiot to watch out for,making that plural Really...Everybody gets to keep their related jobs,parts,labor,sevice,often depends on idiots (small letter) noted LOL

Unfortunately that doesn't work in my area. The traffic signals aren't timed but rather triggered by cross traffic. Once in a while you catch a lucky streak and can cruise all the way to the interstate without cross traffic, other times it seems there is a car approaching each intersection. When that happens it is stop after stop after stop.

dontuknowOH, maybe their thinking is best expressed as this:

"Yellow is saying, 'Hey! Here's your last chance! Hurry up right now, cause once some part of you is in the intersection --even if it's red -- that means you get to keep going!'"

(Ooooops! where did that Mack truck come from...? Oooohhh, crap!!!"

After chatting with many drivers one would be surprised how many state yellow coming on only means proceed with caution/hopeing the car following behind makes it thru too. I remind the Wife,Yellow is signaling to prepare to brake/stop,then I hear Her say "there is a vehicle following me close,two in fact"!

I say just touch your center brake light (r..mirror image) to come on slowing as you go on yellow,let the other Dho-Dhos slide into the intersection,there too close anyway. Tailgating and speed above the limits is the worse factor,short yellows V/S speed,see it all the time,5-10 mpg.over. No Mans Land ............

In Boston, driver's believe that as long as you get any part of your vehicle across the stopline within the first 10 seconds of the red, then you have the right to proceed through the rest of the intersection.

Whenever I pull them over for that, they say, "But Officer, I couldn't stop in the middle of the intersection!"

I answer, "So why didn't you stop when it was yellow?"

"I don't have to stop when it's yellow. Yellow simply means be careful."

One shopping area I frequently visit is often high in traffic and over 4 miles long strip from the basic center of town.Often coming that slower route home I traverse 15-17 traffic lights,normally making 11 of them on green at 37 mph zoned 40 and 45 mph.Great because at least 6 are long lights.

I don't understand the functions when going the other direction,because catching more reds is normal,I have tried different methods to make the greens but only a little success,same lights going opposite direction even at different times,more red caught.The balance of right hand turns,lane seems the same,still puzzled, results in excess idle time,"Something is in the cookie-jar causing stale cookies" Seems... LOL Better gas prices there!

On my to and from work I use the Anthony Wayne Trail. I found that if you travel at the speed limit of 50 mpg then almost all the lights can be missed except for the light at Detroit Ave. Which may throw everything off. This is easier to accomplish when the traffic load is light.

Yes they sure help and are less stressful than a town that doesn't have them , but there is always the driver that thinks they have to be the first from the light and first to the next one.

I have noticed when traveling sync.computer controlled zones mainly 40 or45 mph zones with always heavy shopping traffic the lights always favor the main paths of longer points to points.

when the load has a few seconds of blank flow the computer goes to those seperate areas and allows those interjections to trigger other cross flow,Etc.(local sensors cycle to fill the traffic blanks of heavy main routes at a higher speed,eveninig congestion out.

When reasonable ample distance between vehicles in motion is normal,not stopped B to Bpr of coarse,the sync helps the over all design system to work better if no collisions take place. So what causes collisions,too much damm speed, accelaration/hard braking/no signaling,snatching a close space in lane switching,ETC.probably already know the rest,The Emg..squads, bodyshops,hospitals do know! Even everyones pocketbook($$) knows.Maybe even the Weather.... knows?.
