I'm ontario - our toll roads are camera based, so there's no gates, just pictures of plates as you drive on/off the highway at full speed. Best I've seen so far are motorcycles with a plate on a hinge and a string/wire to lift it. Lots of people with the plastic covers (which are technically illegal - but license renewal offices sell them..), and cops don't do anything about it unless you piss them off. For autos, plates issued a few years ago are peeling, so you can't even see the numbers any more. No cover needed!

AreWeDrunkYet posted:Your maximum speed can be higher than the limit while your average is lower, but your maximum speed can't be lower than the limit if the average is higher. There's definitely a risk of not tagging some speeders, but everyone ticketed was definitely speeding. One of my favorite math classes was during Calc I in college where we got the professor talking on a tangent about a speeding ticket he got out of. He turned it into a supplementary lesson about this exact topic. There's always at least one point where both your instantaneous speed and your average speed are the same for any given trip. If your average speed is above the limit, so was your instantaneous speed at some point. The less your speed changes, the closer your highest instantaneous speed is to your average speed.

About people using a driveway as a road ... https://www.reddit.com/r/legaladvice/comments/d2ubd8/private_driveway_being_used_as_public_roadway_and/quote:Purchased 30 acres of land and built a house several years back in central Florida, had a driveway installed that cuts across the center of my property allowing me to exit on either of two main roads.

The update indicates that he was able to resolve the issue with the county by closing down the private road, and now he's mostly focused on preventing random locals from using the shortcut they discovered. Making your own road is all fun and games until Google Maps discovers it and sends the area's freight trucks through your front yard. quote:Raised hell with the county commissioner for my district, showed them video and threatened to lawyer up, he pulled in the director for the road and bridge department then pulled in the director of zoning and planning.

Any obvious reason why would the lanes for 131 cross over each other at this interchange? Seems like there was enough room to keep NB131 on the right and SB131 on the left.

My guess would be a solution to provide ramps for all the turning movements in a constrained right of way, shifted to the east. All the spaghetti stuff happens in the middle or to the right - a normal full movement interchange would be spreading out towards all the quadrants

Similar in concept to a grade-separated diverging diamond, except the ramps are aligned to merge from both left and right instead of only right.

Anyone have any experience with roadside mirrors? I've seen some tiny ones that are placed a really long way away from driveways/side roads, and doubt that you can process the distorted image in time for it to be relevant, if you can see the road at all. On the other hand, they're not bad in a parking building on the blind ramps, because it's so much closer to your eye.

The correct use case is to install at the mouth of an urban alley or driveway where the buildings inherently reduce your sight distance, so that you can see pedestrians while you inch out Less good use case is rural driveway installed by the owner so he can see if there’s oncoming traffic If the driver has to rely on a mirror to avoid cars, it’s an unsafe entrance.

luxury handset posted:i'm also skeptical of the story, mostly because of this line Assuming he’s on the level, someone in government flagged it in an inventory as a developer road that had been conveyed to the local authority for ownership. Driveways typically don’t bisect a property creating a huge shortcut, so it wouldn’t be too unreasonable for the first maintenance dudes to give him a standard brush off for complaining about traffic on “his road” I would guess that the first few interactions had him saying road or street before he learned the magic words Private Driveway. Still easily made up - but someone building a house in the middle of an enormous lot that takes 30 minutes to circumnavigate is just weird enough to throw a rural county DOT for a loop.

JIZZ DENOUEMENT posted:This is an odd question but what are the most used excel functions by traffic engineers / planners? Concatenate, as a highway engineer I take raw outputs from other sources to turn into Microstation commands, and have to assemble lots of parentheses and commas along with the variables. Or take raw page counts and titles for a sheet index to automatically format them into: 1 2 3-11 12-20 21-25 and automatically update if I insert a sheet in the middle, so I can just re-copy and paste I also used concatenate to assemble a giant list of MS-DOS commands to automatically rename 400 PDFs, and run them from a .bat file I would be pretty surprised if they expected traffic engineers to know Real Complicated Excel Functions, since you'll just be using spreadsheets that were set up once and validated. They're probably testing core excel competency like the difference between A1 and $A1 and A$1 and $A$1 and copying/working with worksheets and making graphs.

Thank you for the response! Yeah they said it is a “beginner” excel exam. The thing is, “beginner” varies wildly based on the audience. Like, I’ve got SUMPRODUCT, solver, index and match, etc. I consider that beginner. But to a boomer manager “beginner” might be like, moving averages and percent change. It’s a really cool job and so I’m dedicating myself to preparation.

pkells posted:Wait, are you saying there’s a way to automatically populate the sheet index (on the title sheet in microstation, I assume) using excel? Because that’s a huge pain in my rear end when it comes to putting together plan sets. Column A - Sheet Name Column B - Formatted Numbering (e.g. "10-15") - this is what we're making Column C - How many sheets in this designation (just a number, e.g. 6) Column E - Number Start (Title Sheet is 1, otherwise formula is previous Number End + 1) Column F - Number End (E + C - 1) Then the only tricky part is the formula that detects if you have one sheet or many sheets (I don't want it to say 10-10 if there's one detail sheet) Column B=IF(E3=F3,E3,CONCATENATE(TEXT(E3,0),"-",TEXT(F3,0))) If Number Start and Number End are the same, returns Number Start. If they're different, returns "Number Start-Number End" You could omit some columns by making the formula more complicated if you wanted to. To get it from Excel into uStation, copy-paste the column of Sheet Names from Excel into Notepad or some other program that doesn't accept rich text to strip out the formatting, then copy paste it from Notepad into a text editor window in uStation. Repeat for your Formatted Numbering column. There's also third party software that really does it ~automatically~ and updates it on the fly, but how often do you really want to update your sheet index. And copy/pasting is pretty fast.

https://www.theregister.co.uk/2019/10/21/traffic_lights_changed/The Register posted:Järlström, who studied electrical engineering in Sweden, challenged the ticket, arguing the timing interval for yellow lights fails to account for scenarios like a driver entering an intersection and slowing to make a turn. A slightly longer interval, he argued, would allow drivers making turns on a yellow light to exit intersections before the light turned red. Even a small timing increase would help – the automatically generated ticket in this case was issued 0.12 seconds after the light turned red. In summary, they're changing the formula for yellow light timing because this guy did his homework. The formula was not permitting for drivers slowing down before a turning manouver.

Hippie Hedgehog posted:https://www.theregister.co.uk/2019/10/21/traffic_lights_changed/ I don't do signal timing design, but I work with the guys who do, and I foresee this getting revised or ignored if it does result in minimum yellows going from 3.2s to 4.5s His problem was not a safety problem, just a regulatory one - an actual cop probably wouldn't give a turning vehicle a ticket if they were slowing to turn and tagged the tail end of the yellow, this was an automated system. And drivers slowing to make turns occupying the intersection during the all-red interval are not a safety problem. And at the same time, giving 1.5s more yellow time to every phase means adding 2-4s of dead time to each cycle, assuming no change in driver stopping behavior But it probably WILL have an effect on driver behavior, because they're going to know that yellows stay yellow for longer than they need to, and cause more people to run a fresh yellow (or what they think is a fresh yellow), which will make things less safe.

Now it makes more sense why people in other countries are complaining about red light cameras so much...

Entropist posted:That doesn't make any sense to me? Do they not measure infractions at the stop line in other countries? That is crazy. What if you get blocked by another vehicle from leaving the intersection although it was green when you entered it, you get a red light ticket? I always learned to pull into the intersection in that situation so you could go after it turned red, but I wouldn't trust technology to make that judgement call on if I was legit. One of the reasons I am against traffic cameras of all varieties, they can't judge the situation. it would be better if every infraction was reviewed by a human, but that kinda eliminates the attraction of them.
