Is the I-4 Ultimate project really going to be 3-2-2-3 the whole way? How badly is taking away one general use lane for a tolled lane going over?

All that landscaping really is lipstick on a pig. I've seen some ok parks integrated under big interchanges like that, but it requires the whole thing to be elevated. These are just really expensive traffic islands, not to actually be used just driven past? Is that why the speed limit is so slow, to force people to admire their tax dollars at work?

People just want to drive fast, so they don't really care. This is Florida. People are a fan of a market economy road system. Especially the suburbanites. Middle class doesn't care about the $10+ tolls, so long as rich people staying in the Lexus Lanes speeds up their commute in the free lanes. What's that? You inner city types want better public transit? Pshaw, no. Bigger roads!

The vast majority of local road projects are expansion from 4/6 to 6/8 lanes with grade separation where those roads intersect. The interstate projects are similar to the I-4 Ultimate project in Orlando, with the addition of express lanes everywhere (though, unlike Orlando, we'll also be adding more local lanes at the same time). Nothing too spectacular, though we'll be replacing the eastbound spans of both the Gandy and Howard Frankland bridges next decade.

I have a question about the I-94/I-90 intersection on the North side of Chicago. Basically, heading South this intersection is always a nightmare. Well, I guess always except when the google satellite is overhead. Here's the Google satellite view of it. Below is a small crop of it for those who don't want to follow the link: Basically you have two very busy eight lane highways merging, and within the next 2 miles or so they need to converge into a single eight lane highway with a reversible 2-lane express lane. Also, there are two very busy intersections coming up within 2 miles of this merge, which probably leads to a lot of cross-traffic. Is there any way to design this so it's not a nightmare? How would you design this if you had free reign? (Also, some people on the far north side of Chicago complain there isn't a ramp to go from I-94 east to I-90 west since O'Hare airport is on I-90) Chuu fucked around with this message at 20:47 on Nov 16, 2014 |

Video game chat! So I've got an amazing friend who's a fancy big time java developer and he's walking me through making babby's first video game. My game is going to be riveting an amazing, it's going to be a regional transport and land use game! Played simcity4? Imagine you're just building the tiles in the region view, never actually going into the city tiles them selves. I'd like as much of it based on actual data as possible. The general idea is that each tile you build (representing about 2x2km of land) you will select a type of street layout for that tile, either a slider or a few pre-set styles. The styles will range from a totally "dendritic" or "hierarchy of streets" sort of suburbia layouts to a dense traditional grid. The former being better for traffic flow and overall car speeds/capacities while the later being much better for pedestrians, transit, and adapting to increases in density. Obviously this is a game, I'm not setting out to make a totally scientific traffic simulator, but if one were to take a 2x2km area and cover one in a network of dendritic or tree like suburban streets leading to bigger streets leading to "stroads" or what ever and another 2x2km area and cover it in a dense grid of streets (where each intersection was generally a light, streets all mostly having equal priority) what would the difference in speeds and flows for cars be on average in those two "tiles" of city? From a traffic engineering perspective what would best separate these two types in terms of "stats" or gameplay? Feel free to throw out some ballpark numbers like "car trip times in the first tile would average 5min and the network would only start to see congestion at X trips per day while the second region would see car trips averaging 8min and the network would start to see congestion at Y trips per day" Of course this is just the STREET layout on each tile, on top of a tile you'll be plopping down large roads, highways, freeways and other things to speed up travel between tiles. For instance building a freeway on one tile basically just represents a stretch of freeway and a single exit/entrance and won't effect travel within that tile (if anything it will hurt it as the highway cuts off routes unless it's elevated) but will greatly speed and increase capacity for people driving from that tile to another tile, or more importantly, people driving through that tile from elsewhere. Any other feedback would be most welcome. The goal of the game is to show how various land use and infrastructure choices effects how a city develops and how for the most part you can only make an area either pedestrian/cycle friend OR car friendly, not both. I also want to include some of the basic political and economic forces that push cities to sprawl in the first place.

I recently found this proposal: http://timandjeni.com/blog/forget-red-light-cameras-we-need-yellow-light-lines/ Several questions get raised, Is this something that people would even notice? Has it been tried anywhere? Would it work? Would it actually change the behavior of those drivers who rush through the intersection half the time and stop half the time? Would this be a possibility according to The Book?

virtual256 posted:I recently found this proposal: http://timandjeni.com/blog/forget-red-light-cameras-we-need-yellow-light-lines/ It seems like it relies pretty heavily on people driving the speed limit, which I don't think can be as much of a given as the author intends. For example, say you were accelerating as you had been stopped at the light previously - that line only works if you're going at least the speed limit at the moment you cross the line and at all points throughout the remainder of the intersection. What if the cars were stopped shortly after the intersection, maybe giving you one or two cars' length of space - you'll have to apply the brakes in the intersection, in that case. In short, I think it works for one very specific scenario - drivers approaching an intersection at-speed with no other real traffic in their direction of travel. I think enforcing a standard yellow length would probably do more to limit people entering the intersection when they shouldn't than anything.

I predict a lot of drivers braking anyway when they see the lights change and getting rear ended by drivers that assumed they aren't going to stop.

I will give this some more thought when I have time, but I'm definitely interested. virtual256 posted:I recently found this proposal: http://timandjeni.com/blog/forget-red-light-cameras-we-need-yellow-light-lines/ Two big things: 1) most people do not travel at the speed limit, and 2) people do not have infinitely fast reaction times. Drivers are already pretty good at judging whether or not they can stop for a yellow. Studies show that they'll stop if they think they're more than 3 seconds from the stop bar, regardless of speed. I'm guessing that's why all yellow times in the UK are 3 seconds. Now they'd have to notice the yellow light, look around for the yellow line, look out the side of the car, remember whether it's even installed at this intersection, figure out how long it's been since the light turned yellow (because almost nobody notices immediately as it changes), figure out how far they've gone past the yellow line, figure out whether they were at the yellow line when the light turned yellow, adjusted depending on their current speed...

I figured it was just a way for light cameras to give people tickets with photo evidence. If you're past the line when it turned yellow and still went through you get a ticket. Won't do gently caress all for safety but might increase ticket revenue. It's fairly easy to get out of yellow light tickets just say "I didn't feel I could safely stop in time".

The issue I'd have is that, just like the walk cycle being timed for the slowest possible walker, for that to be useful you have to space it back for the slowest possible combination of reflexes + braking ability.

We account for people running the red, though. They really shouldn't be ticketed unless they go through after it's already been red for 1 second. Not that cops care, but that's how we design it. Javid posted:The issue I'd have is that, just like the walk cycle being timed for the slowest possible walker, for that to be useful you have to space it back for the slowest possible combination of reflexes + braking ability. Slowest reaction time is about 5 seconds for the old farts we still somehow let drive. Not to worry, though, there are new records being set: recent surveys show that teens think it's ok to divert their attention from the road for up to 10 seconds with no ill effects.

I infer that your country applies the same law as Sweden: If the light turns yellow, you must stop UNLESS it would be dangerous (due to high speed, risk of rear-ending etc). I gather that this is also the case in some U.S. jurisdictions, but not all. (I could be wrong, Source) In practice, I've never heard of anyone here getting ticketed for running a yellow, but then we don't have red light cameras. I do believe the stop-on-yellow rule has helped reduce red light running, and thus security overall. I think the scenario Fangz described won't occur, because when you see a yellow you will be prepared for the car in front of you to stop.

Recently the german police filmed a truck driver (40 ton) who at the same time: Drank a coffee (right hand), smoked (left hand) had a phone call (jammed between his ear and shoulder) and also drove his truck. You can't expect him to multitask this many actions and have a good reaction time? I guess you might expect him to stop, which is what the police did. They also removed his burden of having to drive a truck (for quite some time) and also had the company send another driver to pickup the truck. They are using motor caravans for this and filming out of the back window.

SimCity is a pretty complex game, though, and your idea sounds complex as well; if it's your first project, I would strongly recommend that you not bite off more than you can chew. Especially if it's a solo project, or worked on by two or three people. There's a lot of neat things about your concept, and it would be a shame if none of them came to fruition because you or your team burnt out.

Don't worry I'm going to be starting off very simple, and most of it is just math. The game itsself isn't that technically complex, very limited pathfinding, tile based map. It's just a ton of excel sheets running in the background, which is something I've done before. Once I've got the grid/tile system up and basic pathfinding it will just be a matter of adding more and more detail to the background simulation. It won't have much in the way of economic or political stuff for a long while. Just plopping down tiles and watching numbers change.
