I've been out of DFW for a couple years and in the meantime they finally finished the i-35 construction in the carrollton/lewisville area. What I want to know is what cuntface thought that this was a good idea: https://www.google.com/maps/@32.9943406,-96.9506285,17.24z (the satellite view hasn't updated) What you're looking at is the northbound traffic coming from the bush turnpike gets shunted off to a separate road from i-35 proper, which then gets split up to enter i-35 and the sam rayburn tollway. What's hosed up is that there is only one lane (exit lane style) to get to i-35 and, of course, it always backs up since people want to go north, not north east! The two lanes going to 121 are always mostly empty too. There's something similar on the other direction and in the mornings its even worse than it used to be before the construction. Like, did whoever did the traffic study gently caress up and mix up the 121 and 35 traffic numbers? Cause I can guarantee that while there was a good amount of traffic going to 121, it was almost always free flowing and i used to actually take the 121 exit ramp to bypass the horrible 35 traffic. This whole thing boggles my mind.

Also you haven't done the Lewiston grade until you've done it in a 89 Volvo wagon. That will teach you how to shift.

The Deadly Hume posted:I should point out that that's Cities Skylines (which has a, shall we say, quirky traffic pathfinding model by default though there are better ones in mods) but that's a really cool compilation. Yeah, the "standard roundabout" made it painfully obvious it was CS. CS does not handle roundabouts well (it makes the people on the circle stop/yield) unless you either highway roads or mods. Which is why it had an 8 car-per-minute rate.

I believe the developers are Scandinavian. It's still a really cool city builder/traffic sim though you do have to realize that the traffic simulation is wonky (cars will find the shortest path from point A to point B, factoring in road speed limit. They will not take any other route, regardless of traffic conditions. Admittedly this is done to be easier on older computers.) but there are work-arounds and mods for that. Just make sure you get the mod that kills all seagulls: every one of them takes up a space that could be used for a car and eventually your city finds itself unable to expand because there's not enough models to assign to delivery trucks or emergency services.

I've certainly seen that at plenty of places in the US. Sometimes it appears that it was just because an existing road structure is way over capacity and they seem to be doing that as a stop gap fix, sometimes it's seemingly a developer hearing those round roads are popular, put some of those in!

My states infrastructure body released this transport model for the city last week, pretty neat. Watch it in 1080: https://www.youtube.com/watch?v=_P9dtgLP4h8 Trainlines are the lighter grey lines. The N-S highway directly west of the city is a toll road, and also a section of road/tunnel to the SE suburbs from directly below the CBD (where the train loops around in the middle) Anyway, the big $6.7bn controversial project which was contracted the other week is a toll road & tunnel in the inner west, creating a second (major) river crossing; the West Gate Tunnel (http://westgatetunnelproject.vic.gov.au/). It was an unsolicited project by transurban (toll road operator) which built upon the smaller Western Distributor project taken to the last election and as part of the deal they get to extend the contract for the citylink toll road for 10 years to make even more money. It involved a long tunnel under the river and then elevated roads through the port area before dumping traffic on the edge of the city centre with a spaghetti junction to connect to citylink. Project overview: https://www.youtube.com/watch?v=A9eN5y5mXC4 This is ontop of the completion of the Ring Road in the North East Link project (https://northeastlink.vic.gov.au/) which has sat dormant for 30 years with the shortest route selection (Corridor A) chosen last month with widening to sections of the existing Eastern Freeway which it will connect to: https://www.youtube.com/watch?v=gHLNZO3Cnlo This is somehow costing $16.5bn (with a lot of unrelated work on another freeway widening currently happening bundled into this project) The other routes were longer and more of an orbital completion, linking up with junction of the Eastern Freeway and Eastlink toll road & tunnels, you can see the options here: https://www.youtube.com/watch?v=y_vv_5cvzd4 While in the public transport land there are 50 level crossings being removed (http://levelcrossings.vic.gov.au/crossings) by the current government over two terms, currently costing around $4bn and they've removed 11 so far since coming to power in 2014 (although 3 crossing removal projects were in the planning stages and partial funding from the previous government) while 16 are currently under construction at various stages including the major project of removing 9 level crossings and rebuilding 5 stations on the one (two) trainlines which happen to be the busiest trainline in Melbourne with elevated rail: https://www.youtube.com/watch?v=SYT5F-gcr40 and just today the tenders were awarded for the tunnel construction and signalling contracts for the ~$11bn (including 65 new trains) Melbourne Metro tunnel which has had works happening for the past year in the city moving services and preparing portals for the TBMs to be inserted: https://www.youtube.com/watch?v=rplO_Mp5DDk As well as a trainline extension and some other stuff, basically, cash is being splashed. All up, roughly $38bn in just these projects, with the longest project (metro rail tunnel) to be finished by 2026.

Speaking of modeling traffic flow at intersections with no traffic lights, I was just down in Puerto Rico for the month of November, and large parts of the island were still without power, including traffic signals. That made for a stressful time driving, but it was also fascinating observing how people react in those situations. I thought I was going to die the first time I had to cross three lanes of a divided highway to turn left at an intersection, but by the end of the trip it was nothing. People were just used to traffic flowing like that, and did their best to accommodate other drivers. I’m sure the accident rate skyrocketed directly following the hurricane, but a couple months later, everything seemed like normal, just with lower speeds and higher congestion.

People do tend to drive a lot more cautiously when things suddenly change. It could be that the accident rate suddenly dropped and only started to rise again when people got more used to the new status quo and started running on autopilot and / or taking risks.

So I’m visiting family in Puerto Rico for the week and traffic is incredible. 90% of the traffic signals I’ve driven through are either straight up gone/destroyed or they have no power. People just drive as if every intersection is all yield and it’s both fascinating and terrifying.

Hi transportation thread. I posted this elsewhere but was directed here since more people would want to talk about it: Here's story from the NYT about why subway construction in New York City is hilariously more expensive than anywhere else in the world ($1.5 billion - $2.5 billion per mile, compared to $450 million per mile in Paris). The story picks out staffing costs, "soft cost" inflation, and bad contracting practices (including corruption, though the story doesn't come right out and say it). Includes a guy from London rolling his eyes at NYC claiming the city is too old to do this cheaply, and someone from Paris talking about how they thought their project was expensive but uhhh I know there's an article out there somewhere comparing NYC and other American cities to Europe and Asia but I can't find it at the moment. US cities are generally always towards the top. Here's a thread expanding on the MTA's terribleness and the constant insistence on innovation, rather than just copying successful systems that work in other countries: https://twitter.com/mtsw/status/946488823478972416 See if you can find The Weirdest Guy Ever in the mentions on this thread

Transit in the United States is hilariously corrupt. Protecting the people from "unnecessary risk" by paying a private corporation twice as much to do the same exact thing is all the rage these days. By unnecessary risk, they mean having someone else to blame when incompetence and shortsightedness rears its ugly head, so that politicians and transit leadership can't be held accountable. There are some legitimate reasons for not having certain positions in house, like tunnel construction crews, but they will ride you like a dime store pony if you don't include oversight in the contract. Core day to day operations and maintenance should never be outsourced, unless it's something niche like contracting taxis for overnight transit service. You lose control of your own organization and have to accept the poison pill when the contractor comes back to you for more money to cover cost overruns or unanticipated risk. The normal career path is very much similar to that of a public attorney. Get some experience in public, then go private to chase the big bucks. The leftovers tend to be individuals who are uncomfortable with their own competency (or lacking any), who seek to ride the agency out to the largest retirement pension they can muster.

The story picks out staffing costs, "soft cost" inflation, and bad contracting practices (including corruption, though the story doesn't come right out and say it). Those costs make Amsterdam's North/South line look cheap, even with the 400% cost overruns. 9.1 kilometers partly tunneling under the medieval city center built on wood pile foundations was originally budgeted at €750 million, now nearing the end €3.1 billion has been spent (it will probably stay under €4 billion). So assuming the final costs will be €4 billion that is ~$5 billion for 5.6 miles. Of course it's probably much harder to tunnel through Manhattan rock than through a swamp under a 750 year old city.

The part of the system built in the 70's caused huge riots because the method of construction was to just bulldoze a path through the city, construct the tunnels and build new buildings on top (you can see the scars along the wibautstraat/weesperstraat, suspicious ammount of new buildings along that corridor). So in 1975 they stopped extending the system. The recent extension under the medieval part of the city uses a technique where they freeze the ground before drilling a tunnel in the shallow parts and the rest of the tunnel system is just really deep. Even so it still damaged some buildings.

Except they never closed the tunnel back over, and left it as an open-cut section that is often referred to as a "ditch". It's one of the early examples of projects successfully stymied by Environmental Justice concerns, after the outcry from this first section.
