It’s the people not zipper merging correctly. You have idiots entering that are not up to speed and you have idiots breaking for the idiots not up to speed.
On ramps should be required to have their lane not end abruptly which causes the panic. The on ram should continue for at least a 1/4 mile.
idiots breaking
I’ve literally seen a test with 4 cars driving around a circle, and they tell the drivers, “go at a consistent speed and maintain the distance in front of you” and after 5 minutes they’re all bunched up on one side of the circle. No amount of zipper merging and nice ramps will fix this.
The best flowing highways I've ever seen were ones where the on ramp didn't end, but became the off ramp for the next exit. Obviously you can't have that everywhere, but it's basically a free flow lane that gives time for adjustment. I've also seen on ramps (older ones) that aren't much more than a turn lane, and dangerous if you don't know the area and traffic patterns.
The issue with this style of lane design is it basically doubles the amount of lane changes that lane experiences, which can make it the most dangerous possible space if exits are close together. I’ve lived around Dallas. It’s scary.
My area kinda has this except the on ramp ends quickly merging into the right lane, then the off ramp starts almost immediately after. It makes traffic worse as cars trying to get on cannot merge effectively because cars want to be in that lane to exit. I find the best flow is having the off ramp before the on ramp, which minimizes right lane conflicts.
people not zipper merging correctl
Zipper merging is more complicated than driving straight forward and requires both lanes to slow down significantly relative to the cars in front and behind them.
The biggest issue with zipper merging is humans need to not be selfish for it to work. Its very efficient when moving well and everyone is in turn, as soon as 1 asshole sneaks in or prevents a merge, it causes the entire flow to stop.
Cars cause traffic. Cars changing lanes causes traffic. Cars merging causes traffic. Only solution, get rid of the cars and the system built to cater to them.
This is the correct answer. There isn’t a city on earth that has fixed congestion by building for more cars. It’s the places that build for trains and bikes that are best for driving, ironically.
Adding to this, more collector-distributor roads that parallel the highway on both sides to reduce the weaving of people entering and exiting.
This is also why I hate cloverleaf highway intersections, the merge period is way too short and the speed delta can be high.
Just one more road bro it will fix traffic
