the only thing that the rail line next to the highway does is provide an easy smash and grab parking lot, and take up space that could be used for something productive like a green belt and extra lanes.

if your new higher capacity roads are congested it just means you don't understand the actual demand. new traffic doesn't appear from nowhere, it comes off back roads that everyone was using because the main roads were poorly planned.

some time ago, Georgia's previous governor made a deal with some toll road companies. they took over part of the HOV lane north of the city, converted it into pay-per-mile poo poo. the mileage fees would change based on congestion so that on bad days you paid more, on light days and weekends it was cheap as poo poo. at first, it got zero usage. since it basically took a whole lane away from traffic, and multi-passenger cars suddenly didn't want to ride in that lane (carpools were still ok to ride free but they had to 'register' for it ahead of time and it didn't work well), traffic in the other lanes became a severe problem. this wasn't really solved until they lowered the costs so much that the fees were trivial, causing the whole system to lose money rather badly for several years. somehow this was evidence of success and they announced deals to build these toll lanes to other roads. but Atlanta being Atlanta, traffic got worse. people started using it more out of need than convenience, and the prices got jacked. didn't matter: traffic was so bad people were willing to pay. hit a record high congestion fee recently. it's also no longer convenient at all, because the toll lane is as jam packed as everything else. so much so that now they're looking at offering credits to regular toll lane uses who decide not to use it during peak hours. "the local paper posted:The state will roll out new toll lanes in Cobb, Cherokee, Henry and north Gwinnett counties, but troublesome traffic has caused the existing Gwinnett lanes to slow below federal standards at crucial times. going to all this effort to avoid trying to fix the problems with our rail system.

oh good. some random british dude came up with some theory with no evidence back in the 60s so that must still be true. you don't have any visibility on end to end travel across all routes so claiming "well it just appeared from nowhere!" is the best you can do.

also road dieting is just diversion to other roads that you aren't currently studying

HOT lanes are poo poo garbage but even regular HOV lanes are entirely worthless for congestion reduction we know this b/c people aren't encouraged to carpool due to them, and that trip times appreciably aren't reduced by using them at best they have zero impact in every single instance you're better off just having another normal lane (well really you'd want a dedicated bus lane but lol at that happening) HOT and HOV lanes are only ever pushed by people who want them installed for reasons other than congestion reduction

shaggar do i need to remind you that i'm a licensed transportation engineer the way you seem to think things work on roads runs counter to an entire body of knowledge that it's literally my job to know 50+ years of study and real world evidence show us that these behaviors are true, it can't really be argued like at all

induced demand is a myth to cover up bad planning and a poor understanding of the pre-existing demand and how it was being served.

here's an induced demand study from earlier this month done in your home state of canadia it's a thing that's constantly being examined in different contexts and denying it makes you sound like one of those fluoride mindcontrol weirdos quote:Ignoring generated traffic results in self-fulfilling predict and provide planning: Planners extrapolate traffic growth rates to predict that congestion will reach gridlock unless capacity expands. Adding capacity generates traffic, which leads to renewed congestion with higher traffic volumes, and more automobile oriented transport and land use patterns. This cycle continues until road capacity expansion costs become unacceptable.

hp is there highway planning doctrine that endorses removing transfers between highways? in nyc there are a ton of highways that will weave in and out of each other and it seems that so many interchanges would slow down traffic because of the constant merges and exits

wait until shagger finds out that in actual cities, development happens and people move in. for example, the LA metro area added the entire population of Maine in the last 5 years alone. and home owners and renters #1 criteria pre-move in every study? location and ease of getting to work.

I count roughly 25 lanes in that mega road photo. At 1800v/h that's about 23000 people in each direction, assuming it is all single occupancy vehicles. Proper metro systems have a capacity of about 30000 in each direction.
