Yep. Don’t forget about the worthless ones they just added on River Road, Nicholson and Burbank.

it sends a tiny text packet that essentially says: "Northbound lane has 5 cars, average speed is 35 mph, pedestrian waiting to cross."
quote:It's the coordinating of the broader grid part that is a lot harder than it might seem. Keep in mind, if your intersection is emitting tiny packets of data, it will also be consuming tiny packets of data from multiple other sources. And all those tiny packets will have to be consumed by some machine and considered as a whole before emitting new packets to the edge.
Because of EDGE AI, the central city server doesn't need to be a supercomputer. It just acts as a dashboard collecting tiny status updates and coordinating the broader grid.
Consider an accident 10 lights away... how should your intersection handle it? We want to avoid creating a mile of congestion that cascades down every cross street, right? Maybe the optimal strategy is to start delaying traffic within a certain radius from approaching the accident and accelerate traffic moving away from the site of the accident. Prevent congestion in the area by slowing vehicle accumulation and speeding dispersion. Responders can get to the accident and do their jobs faster, making it better for everyone.
As for the traffic we intentionally delay, do we let their navigation re-route independently, or do we send signals to coordinate their new routes to optimize? It's a lot to think about.

Spacing of signals also makes coordinating both directions impossible sometimes. Downtown areas are easier with standard blocks and one-way roads.
Typically, making one direction better screws over the other direction with variable distances between intersections.
And contrary to popular belief, roads do not have unlimited capacity. A lane of traffic will only accommodate 1,800 vehicles per hour on a 55 mph speed limit with no stops. When a lane or signal gets more vehicles loaded on it than it can handle, you get stop and go traffic on the interstate or sitting through lights for multiple cycles.

So, what happens when people average 45 in a 55? Does that perhaps cut the capacity of the road? I'd like to shut up the "Speed limit means I'm allowed to go a lot slower, you can never be too safe," crowd.

It would also be nice if bolts shot up from the street to prevent people from running red lights 2 seconds after they change.
frick that.
I'll stop running red lights when traffic engineers get their head out of their arse and fix the lights.
There are so many stupid arse light scenarios where you're light turns green and the next light a quarter mile up the road turns red right when you get to it, even if you go the speed limit.
For example, i'm on Airline going north and i'm sitting at the red light by Parkview Baptist. I can be the first car at the light when it turns green and the only way i can get the green light at Siegen is if I gun it and go 70 mph. If i don't do that, the light will turn red right before i get to it.
Make that make sense.
If i'm coming down Lobdell towards Jefferson Hwy, and that light turns red right before i get it, I will literally catch every single red light going down jefferson unil i get to Airline. I'll wait at the red light at Jefferson and when it turns green i'll turn left on Jefferson and then get a red light at goodwood, then a red light at Bocage, then a red light at Essen, then Drusilla, Bluebonnet and the stupid arse light at the circle K before getting to Airline.
But if i run that red light, or, if i turn right onto jefferson and make an immediate u-turn on jefferson to head towards goodwood/essen/bluebonnet, then i will usually catch every single green light.
Same kind of crap happens when you're going down Perkins. Once you catch one red light, you'll catch them all, but you make one illegal move and you'll catch almost all greens.
Just this morning i get off I-10 West at bluebonnet and wait at the light to turn left. It turns green and 4 cars get to go before it turns yellow. The person in front of me, the 5th car ran it and so did I. It was green for like 5 seconds. There's two lanes that are about a quarter mile long and you get 5 seconds? I can be on Pecue coming from highland and the left turn light at Perkins will stay green for 15 seconds while not a single car turns left there. There's a left turning lane big enough to hold like 3 cars, yet they get 15 seconds to turn.
it's stupid shite like this that needs to be fixed.

Yes. Lower speeds result in lower capacity.
But... people running into each other every morning/evening is REALLY bad for capacity.

How about the fricking red arrow trying to turn left onto Goodwood from Jefferson?
I treat that bitch as a yield/green every time because there's rarely oncoming traffic!!
All that shite needs to be fixed.

The bigger problem with going 10 under is the speed variance it creates which leads to more accidents.

What’s the proper timing sequence for the lights north and south of I-10 on highland, the light at Perkins and Highland, and the light at Perkins East and Highland?
Dynamic based on conditions at the given time.

Like merging onto a 65mph interstate doing 40 (with plenty of acceleration distance to achieve 55+?)
There are two on ramps I pass 20+ times a week with a 1/2 mile or more of acceleration room onto I-10, one of them is in a 75mph zone, the other in a 65. The one in the 65 zone constantly has *all of I-10 Eastbound* farked up for miles, multiple times a day, and I'm convinced it starts because people are merging at too slow a speed.
Tens of thousands of vehicles a day impacted. But NPC drivers don't care.

The only answer is dumber AI in dumber areas. This way it will account for and relate to the average idiot in a given area. ‘Artificial Stupidity’ if you will.

Nothing quite like driving on Airline Hwy between where Jefferson runs into it and where the Kleinpeter facility is. If you were to ever make it through there catching less than 3 red lights, you should spend your bank account on lottery tickets.
Though nothing will trigger me like a light turning red when legit no one is even at the intersecting road.

This may be one of the best initial uses of AI. Just think, AI, if programmed with all traffic info, can adjust lights throughout a whole area to maximize safety, fuel efficiency and time management.

I just nominated Old Hammond + Chevelle Dr. in Baton Rouge to get a free LiDAR sensor.

Did they ever fix intersection of Airline highway with Siegen and Sherwood Forest? That was one of the worst from BR. Haven’t lived there in 5 years

Some of it is already done with computer programming an modeling.
There is a guy on the Mississippi Gulf Coast that works on traffic lights with a YouTube channel.
TrafficLightDoctor on YouTube
He also does Facebook Videos too.
I think most of our problems have to do with lack of maintainence from DOTD and idiots that don't position themselves in the intersection where their car hits the right sensors to call for a greenlight.
Here is a video of him comparing Mississippi vs. Alabama.
I would hate to see the LA to Mississippi comparision.

The Japanese solved their traffic problems by studying mushrooms
Explain...
They created a maze of their Subway System and used Mushrooms/ Fungi hoping it would complete the Subway maze and track it.
The Mushrooms ended up completing the Subway maze and THEN re formed the Subway System to the most efficient routes/ system.
This is a very dull and limited summary but I believe its the gist of the study.
They wanted the Mushrooms to complete a maze and it re created the maze more efficiently than it was before. The maze happened to be their entire Subway System.
They can also rewire/ strenthen your brain by reconnecting/ refiring neurons. Its why they are being usedin early studies for PTSD, Alzheimers, and dementia.
