- Imagine the possibility of driving non-stop from where you are to where you're going, instead of being constantly delayed. Traffic congestion costs U.S. drivers hundreds of billions of dollars annually, and a solution to this problem is an idea whose time has come. David Nguyen talks about how drivers can get more green lights with their phones, and explains a solution he has already started to implement on real roads. David is a former automotive engineer who recently launched ThruGreen, a smart infrastructure startup with a mission to give everyone more green lights.

In the best case scenario, this will only generate more induced demand. The solution is to stop building suburbs and sprawl which only force people to own a car to go anywhere, even to the park. Cities should be compact as they were in the past, density would allow mass transit with short headways and also would make bike commutes and pedestrians multiply. Cars with one person on board will never be the solution.
and pedestrian safety?
One of the more interesting things about city speeds and speed limits is that setting them low frequently makes it safer for people AND eliminates stop/start traffic because you don't have people sprinting between jams.
Many inner cities have actual traffic speeds of 5-10mph and if you set the speed limit at that, you wouldn't actually NEED traffic lights (particularly if you move to roundabouts to replace lights and 4-way stops)
The small town I was born in had 20 sets of traffic lights in 1969. Now it has 3 - and a crash rate that's 90% lower. The difference is roundabouts, lower speed limits in the shopping streets and traffic furniture which doesn't encourage speeding (drivers travel at the speed they assess as safe - and adding more "safety features" actually speeds traffic up whilst simultaneously causing drivers to pay less attention to conditions as they believe they're more insulated from them.)
Sweden and the Netherland both have a very interesting approach to speeding - long range detectors (or messages passed between lights in urban zones) so when speeding traffic is detected, lights go RED and stay that way for a few monutes. No fines, no cops hiding behind billboards. Instant effect
Remove Traffic lights. convert all intersection to round abouts
Is train or public transportasion
Lucky will be the first VC or vehicle manufacturer that gets to you to...
WOW this is amazing
do you guys not have phones? no.. we dont. also i seem to remember being lectured on distracted driving.
0:08 Yes......and almost killed myself
It would be better to put cellular technology in cars specifically for local safety, rather than using cellphones. Nobody will adopt the same app, it is mandatory that this exist in every car and the cost to the driver should be nothing, it should be a fcc requirement of cellphone towers to offer this service.
let a massive super computer crunch the numbers of millions of vehicles, give feedback to drivers and control lights!
and then a hacker gets into the system and causes chaos.
Dude, traffic is caused by too many cars, not by traffic lights!!! smh
So what is the answer? Get all cars off the road?
@@christaylor6502 Traffic means you can't fit all the cars on the road. There's not enough room. So you can build more roads. Unfortunately, there is no place to put the new road. So that's not an option. The alternative to making the roads bigger is to make the cars smaller. Cars are way, way, way, way too big. The solution is make cars the size of a person sitting in a chair. Replace cars with electric pods the size of a first-class airplane cabin. You can then fit 10 times the amount of cars on every road. It is the equivalent to adding 10 lanes to every lane on every road. You can turn every 2-lane road into a 20-lane road and every 10-lane highway into a 100-lane highway. That will end traffic.
@@kajmobile OK. Educate me what is the answer? I'm my city while yes more cars on the road it doesn't help turning 2 lanes into 1 to enable buses and cyclists which are empty half of the time. The traffic light systems are antiquated, I have lost count the amount of times I am stuck at lights with no traffic coming from any other direction. So are you saying ban all cars?
@@christaylor6502 I said my solution in my comment! The solution is make cars the size of a person sitting in a chair. Replace cars with electric pods the size of a first-class airplane cabin.

Suburban sprawl is the problem, all dense cities allow people to walk, bike or take transit to any destination. Forcing people to have a car to go everywhere is a crime, and you are now paying for it with this huge commute times.
