I tried splitting it into west and east halves (since it's about 3 miles long but only 1 mile high), doing one route at a time, and doing one direction at a time. Nothing looked right... I think I might just make a separate map for each interchange.

peepeepants posted:It is a wishlist of projects and goals that your area wants built over the next 20 or so years. Some of them are big awesome plans in the same way I have big awesome plans for after I win the lottery. Many projects will never get built because the money won't be there. It is the result of a process that involves getting local governments, transit agencies, special interest groups and others in the metro area to come together and rank what projects are the most important given the amount of money they have. Take a close look at the “financially constrained” Transportation Improvement Program scenario because that is most likely what will happen. Some aspects of the plan require governments to change policy like zoning code, which might not happen or get watered down by the political pressure. Going to public meetings about these plans are neat. It is a chance to sniff out "bridge to nowhere" type things and check out how they collect data for their traffic computer models. The planning part is the light blue and green bits of this "easy to understand" flow-chart. It is for New York but your state or city process is probably something similar. Transport plans are awesome when they work, in 2007 Transport for London said they wanted to make this all happen by 2025 And here's what we're getting So it's not far off. We gained some train lines that already exist anyway and are being handed over from one train operator to TfL, but lost a bunch of trams because Mayor Boris is a huge idiot who decided to waste £60million pounds on a cablecar that is used by four (4) regular commuters and a bunch of bespoke busses that are no better than ordinary ones, cost more to run and are more expensive to buy.

Apologies if this question's come up before, but who are we supposed to contact to report a traffic signal that's (apparently) not operating correctly? From the building where I work I have a clear view of a four-way intersection. Over the last year or so I've noticed that at random points during the day (but usually somewhere between 4-6pm) traffic from one particular direction doesn't get a green light for anywhere up to 6 or 7 cycles, sometimes more, which translates to about 10-15 minutes between green lights. This results in the road leading up to the intersection (and various side roads that feed into it) getting crazily backed up. Drivers who work out what's happening get into the right lane to do a right on red, which eases the back up a teensy bit, but most people who want to turn left or continue straight ahead just sit there like lemons for those 10-15 minutes. It can't be deliberate because none of the other three roads at the intersection get backed up enough to warrant it. I'm guessing that there's a faulty sensor involved, because occasionally if I'm sitting at the intersection at midnight, when there's no other traffic around, it won't give me a green light unless I reverse and move forward a few times. But the fact that it consistently happens between 4-6pm most days suggests another issue. The fact that this has been going on for a year either means that a) no one else has reported it, or b) it's been reported but is apparently a low priority for maintenance. Is it common for an obvious fault such as this to go unfixed for so long? Retroblique fucked around with this message at 06:36 on Apr 21, 2014 |

My city has a 311 service in place that you can call to report stuff like this. I've done it twice for burned out signal lights. Yours is rather more subjective than that of course, but it seems like the place to start.

# ? Apr 21, 2014 07:27 |

It varies by jurisdiction how maintenance of things like roadways and traffic signals are done. I would begin with your State highway department. There's a good chance it won't actually be their responsibility, but they are likely to be the most responsive and can tell you who is actually responsible. If you give us the cross streets, we could probably zero you in on the agencies to try. A year seems like a long time for it to go unfixed, I would report it nonstop until they fixed it. And fun fact - where I am, if you are at a light and it goes through two cycles without giving you a green, you're allowed to proceed when it's safe to do so, through the red light.

In our case, the simulation is fantastic, but the input data's mediocre, so I don't put too much stock into the details of simulation results other than "traffic backs up here, especially in this lane."

I doubt it. The truss is 65 feet long and weighs over 200,000 pounds. They needed every last inch of room for 8 lanes of traffic (6 local + 2 express), hence the lack of a center support. 64 feet worth of traffic lanes, plus a foot for the jersey barrier.

Ok dudes, let's deal with this situation. The north-south route has right of way, no stop sign or traffic light. Despite the number of cars shown, it's not a busy road, mostly just trucks for the industries around here. The road to the left is a small local road (that will have a stop sign). The northern most track just crosses the intersection then leaves the road to service an industry. The next track though goes down the entire northern lane for a good block then turns off the road and into an industry. The bottom two tracks are a pretty simple grade crossing but there's obviously an issue of people stopping on the tracks while waiting to turn left. At the minimum how should this be signed and painted ? I know you're going to say I should have actual cross-bucks or what ever, but how would those cover the street-running track? The bottom most track in the picture is the only one that will see frequent use as it leads to a container terminal so double-stack trains will be using it daily. The street-running track and siding would probably only see weekly use. How the gently caress would this be handled? Not necessarily how would this be handled if it was built new today, but how would it be handled if this situation had existed for the last 100 years and it was tucked away in an industrial zone? Also check out those hand-carved cobbles. Street running can be pretty crazy. I don't see any flashing warnings or bells here.

Groda posted:Yeah, that's really not true. Some countries, mainly in Europe/Asia, have much tighter rules about street running. South American/North American/African countries take a more laid back approach, especially when it comes to rail spurs that only see a train or two a day.

Install Windows posted:Those trains tend to lay on the horn quite often while street running too. I know that here, the protocol is basically stop at the intersection, lay on the horn until people get the message and stop, then crawl through while keeping the horn blaring. Several minutes of constant train horn deafening everyone nearby, but at least there aren't typically any accidents. Trains only run through there about every other day or so.

The problem with my situation is that the rail line is going down the west bound lane. Meaning if the train is going east, it will be going the wrong way and the lane will need to be shut down. I'm sure it would be as simple a flag person just walking to the end of the block and stopping traffic for 5 min. Reasonable? It wouldn't be anything other than a loco and a couple cars going down here, so could stop almost at tram speeds. Also wow I love that rail bridge over a highway at grade right next to a sidewalk with no railings of any sort. Good work. Baronjutter fucked around with this message at 16:21 on Apr 29, 2014 |

Well, it's not quite the same, but over here, when there's an intersection with traffic lights right next to a railway crossing, it seems they somehow integrate the two. First of all, you're never allowed to stop on the crossing, so the traffic lights for the cars approaching the intersection through the crossing might be placed before the crossing. Secondly, when a train comes, there's the normal warning signals, but in addition to that, any traffic lights leading to the railroad crossing will stay red, while the lights for directions not through the crossing will stay green, preventing traffic jams as much as possible.

How should the whole area be signed though? Obviously have a railway crossing sign before the tracks on the bottom, but with the tracks immediately to the right of the left road where would you put it so that it gives people turning right warning? I guess I should wade through this poo poo: https://www.tc.gc.ca/eng/railsafety/grade-crossings-standards.htm Is there a special sort of sign that basically says "yo if you turn right there's going to be a train track right there so like be careful, maybe stop back here if there is otherwise you'll be caught in the intersection" ?

Varance posted:Train braking systems aren't as antiquated as they used to be. You'd be surprised how fast you can stop a freight train on a flat plane. Heavy load, 50+ cars highballing at 50+ MPH? Yeah that'll take a mile or two. Most street running trains are traveling no faster than 10 MPH and are usually no more than 10-12 cars in length (and if you have a heavy load, you'll definitely be taking it slow with someone on the ground protecting the right of way). Under those conditions, you can and will stop on a dime if you go into emergency. Speaking from experience on that one. It's true that braking systems are improving, but it's also true that that train took ~500 feet to stop, while a tram would have done it in about ~100 feet and a bus in about ~50 feet (assuming it was travelling ~20-25 mph).
