Carbon dioxide posted:The solid lines are usually actually small curbs. A turbo roundabout is designed so you can't really get in the wrong lane, and you can't go round more than once, because if you gently caress up you will be forced off at some point (often the last road before the one you came from). Each lane forms a sort of spiral. If people follow the arrows and signs from the start, they will end up where they need to be and they won't have to cross other traffic in the middle of the roundabout. There's a roundabout near me that requires me to exit onto the road I entered from in order to enter the highway in the direction I need.  http://goo.gl/maps/Zn5B8 Getting from A to B to get on the highway requires you to use the roundabout as a U-turn. Is there a design that forces an exit but still allows U-turns?

nimper posted:Near as I can tell the turbo roundabout allows U-turns. You just can't go around more than once. Hah, welp, I totally did a dumb when looking at that drawing the first time, you're right. But this only works if you enter from the top or bottom. The "east/west" entrances don't allow for this.

Carbon dioxide posted:traffic gets horribly clogged behind you. That seems counterintuitive. Why does traffic behind a car doing 5mph clog up worse than behind a car doing 10 mph then 0 mph then 10 mph then 0 mph etc.?

Varance posted:Florida doesn't give a care, unless the transponder whiffs because you hid it under your seat or something. $100 UTV (unpaid toll violation) fine every time that happens, reduced to toll plus $0.25 if the road has been updated to toll-by-plate (+$2.50 per month for the first time you get tolled by your plate each month). UTV also triggers if your account has insufficient funds or if the license plate doesn't match the transponder. Massachusett's transponder is packaged with a couple strips of adhesive velcro, so I can detach it from my glass whenever I want and just leave the velcro. I've done this to trade transponders with my parents a few times so they can pay tolls on long trips. Also if the Mass toll booths don't read your transponder, they send you a letter with a picture of your plate that basically says "Hey if you have a transponder and we missed it, write down the serial number and mail it back to us with  and we're cool."

Baronjutter posted:When I used to work architecture any and all public hearings are old people and they are against everything. I went to my local monthly civic association meetings for a year to see what my community was up to. For 11 months of the year, it was nothing. One month, a Vietnamese man wanted to build a house about 6 inches too close to his property line, so he needed a variance. The city wanted to hear from our civic association about how they felt about the variance. I have never seen so many angry, racist, greyhaired white people in my neighborhood, and they all showed up to bitch over 6 inches on a lot to which none of them even abutted an abutter.

Echo 3 posted:A few old-timey traffic signals in Massachusetts used to use circular red + circular yellow to mean an all-pedestrian phase. The last one that I knew of was replaced with a normal ped signal a few years back, though. There are still several intersections controlled by blinking green lights in Boston.

Echo 3 posted:I typically see flashing green in front of fire stations, meaning "this light will always be green except when a fire truck is pulling out." Is that type of usage not in the MUTCD? Flashing green is specifically advised against in the MUTCD: MUTCD, 4D.04.D posted:A flashing green signal indication has no meaning and shall not be used. The flashing greens I see around Boston/Cambridge/Somerville usually denote "green, but yield to any pedestrian." But I'm not really 100% on that, since some of them are placed in locations that don't make much sense for that purpose.

Cichlidae posted:Yup! Check it out: http://mutcd.fhwa.dot.gov/htm/2009r1r2/part8/part8b.htm Interesting link! I googled some of those signs, and this image was one of the results. What exactly is the use for the sign in that image that says "150 Feet between highway and tracks behind you."? I'm having trouble imagining a road/rail arrangement that would make use of that information on a sign.

Or just setup a souvenir shop at mile 420 and sell real actual state-issued Mile 420 signs for some huge markup?

SurgicalOntologist posted:Huh. I don't think I've ever seen a flashing yellow arrow in many years of driving around CT, MA, and RI. I guess I will soon enough. Yeah but we've got flashing greens around Boston. A flashing yellow wouldn't be the least intuitive traffic control device I've seen by far.

Opals25 posted:Don't block the box! If you're turning left but only waiting for oncoming traffic to clear, you should enter the intersection until traffic clears, then finish the left turn. New York, for example: http://dmv.ny.gov/org/about-dmv/chapter-5-intersections-and-turns

It costs $1.25 an hour to take up a street spot on Boston common. I once circled the common and public garden for 40 minutes without winning a spot.
