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

City in Washington went the other way. They wanted "traffic calming" and set the lights to stop traffic from going through too fast plus changed four lane roads to two lanes and hoped that some people would stop and shop there. All that resulted in was frustrated drivers who began to find other ways to go. I heard it's still causing problems eleven years later.

Around here, lights are centrally controlled, but not by a rational computer system :)

Why? What evidence have you ever seen where government (or bureaucrats) will make more work for themselves?

Vehicle presence sensors are a GREAT help. At 2 in the morning, with no cars in sight, the sensor gives you a green light right away.

Proper traffic light implementation is abyssmal in many areas. Efficient traffic flow is just not a priority .

"Liberal" isn't really the correct word. Big-government Progressive is.

It really isn't as simple as hurricanejim would have one believe. Traffic synced in one direction is usually blocked in the other.

My thoughts are the Sync. would help as long as other trip sensors are used as a short time release at certain areas residual traffic.

Our lights local wont give a left turn arrow if there is no more than one vehicle waiting in line to turn. Also when the traffic pattern is heavy in group formation steady the computers hold those areas green, seems so that until a broad flow gap occurs. A pattern change takes place as temporary.

I have often traversed 13 Greens in one direction often, but only 8 going the other way, mainly because right lane turners slow the pace(same lights)but much Mall design entries have the bottle-neck along with poor right turn exits for roads in that direction = more reds caught.

Property boundaries and few service back lanes are few by design, a shame because that would help, (stupid zoning/aged stuff) of the past, and poor landscaping elements, messes large delivery truck entries, causing much repeat damage/dumb do-overs! Maybe ZOO architects were in the plentiful era ....? PLentiful Era, ETC.. did I mention that, TEA Time......

I've noticed the one road I drive often has the lights synchronized, which makes it a nice cruise home. It doesn't happen often though, that I hit the greens lights all the way home.

Some people are very good at doing just that on their own. If you drive the same roads enough and are observant, you can probably do it as well.

Yes, many drivers don't realize what is going on, so don't get much benefit from sychronized lights. They continue to drive in a mind numbed state racing from one red light to the next.

Synchronizing stop lights is not necessarily a priority for traffic engineers. With synchronized lights, people tend to approach intersections expecting the light to be green and when it isn't, bad thinks can happen. Oftentimes, lights are purposely left unsynched to cool down traffic flow.

the first smart post I've seen in a long time-
it is very true that traffic flows better when the lights are in Sync.

where I was raised they were synchronized and driving was mush more pleasant.

Arlington Va is the perfect example of needing help in this department. Those liberals scream how green they are, but their traffic lights are a joke.

That should be done across the country. There is absolutely no reason to stop at each light without any traffic in the side streets.

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.
