I'm on the lowest rung right now, I can mostly only answer questions about how we do things at an operational level. The political process for keeping Limebike in operation is wayyy above my pay grade. That said, its a huge challenge keeping up with the number of 311 calls we get for blocking right of way or illegally parked bikes. Our ticketing system for this only lets a handful of people log in to one of the 7 zones Dallas is split into, so my co worker and I got hassled yesterday for blocking someone from getting on as he was showing me how to use it. Vandalism and maintenance are huge problems. The first is kind of obvious , the bikes are all over the place and some of the destruction is honestly impressive. I did the Trinity Groves / Continental zone and our van had a grappling hook for retrieving bikes that get thrown into the Trinity river. If a bike is totaled/ red tagged its because of major structural damage / a missing lock mechanism / or if its been painted over because we dont have a paint booth at the warehouse. For a fleet of 10,000 bikes, we only have 2 mechanics who don't have stands to hold the bikes up or the special tool needed to properly remove the security bolt that holds the rear brake line. The vast majority of organizational effort and grunt labor is spent on redistributing the bikes. Driving around in vans and picking up bikes, doing field repairs for stuff like kickstands / brakes / grips - which more often than not doesn't get done due to the pace expected of us, and dropping them off in neat groups (where we're legally allowed to have them set up). We have two 7 hour shifts a day doing this every day of the week including holidays. Theres probably something more interesting I could add about our operations apps or something. I'm kind of worn down from lifting 55 pound bikes in and out of vans and stressing out about going out of the way for wrecks or to find better deployment zones. One of the shift supervisors just posted in our slack that day shift deployed and rebalanced fast enough to pass the 4000 ride quota he decided on. Hopefully night shift gets their 1600. We obviously have no control over how many people want to ride our bikes but the number of deployment zones filled with working bikes is a big part of that I guess. Please let me die.

There was a limited deployment of lime bike near where I live. I am cautiously optimistic, but I can't imagine how it can be sustainable at the current $1 ride rate while accounting for keeping the fleet in order. Bluegogo already showed us that you can't just dump a bunch of bikes in a city and ignore them.

I didn't realise the bike share companies were Dallas exclusive, I kind of assumed they hit every where at once. I like the idea and have used them a few times, but yeah I have no idea how it's sustainable and 50% of the bikes I see look vandalized to hell.

Limebike for sure isn't Dallas exclusive, but we happen to be their largest market / operation and I have no idea how that happened.

I know that many other cities severely limited the number of licences for the bikes. Maybe that just didn't happen in Dallas?

Qwijib0 posted:What are the economics of moving bikes with a truck from point a to point b, vs just making trips in that direction free or even earn you a buck in credit or whatever? I don't think it's been seriously considered based purely on gut instinct. In Dallas, our warehouse location is south of Interstate 30 - a purely industrial neighborhood I wouldn't want to be in at night. There's little in the way of public transit, and people riding bikes in bourgie neighborhoods would never consider it. They might be able to incentivize riding towards a central point where all of our collection/deployment zones are centered, but without a central location to park I don't know if the resulting mess would be worth it. At $1 for 30 minutes or whatever we charge the local barflys and dorks any viable incentive for us probably wouldn't be worth it for most people. I really only notice that the bikes are 55lbs when I'm trying to roll 2 at a time up the Trinity River Levee. It's deceptively tiring, even for people who aren't secretly troons with hormone reduced upper body strength.

Not sure if this is the place, but why might a construction zone have an orange sign for a stop light that was there for well over a decade and hasn't been changed in the least?

Do you mean a W3-3 as shown on this link? https://mutcd.fhwa.dot.gov/htm/2009/part6/fig6f_04_1_longdesc.htm Is it orange like that shows, or is it the duller yellow like the W3-3 on this page? https://mutcd.fhwa.dot.gov/htm/2009/part2/fig2c_06_longdesc.htm In either case, it's just a warning sign that says "Look out, there's a signal here". Best reasons this could be added in temporary orange: At some point, they're going to muck around and make lane changes or other stuff that are going to confuse people, and new drivers to the area might be less likely to notice the signal as they come upon it. Bad reason it could be added in temporary orange: A lazy reviewer didn't want to look at the plans so they just offered an "Add a W3-3 sign" because it's easy and makes it look like they're doing stuff

Is it just the traffic signal sign that changed? Sometimes the agency that owns the road will require all the existing signs get replaced with the contractor's own during construction so their signs don't get hosed up or lost.

It's used in, for instance, NYC's bike share system, but as a supplement to trucks rather than a replacement. Some people will take rides that are useful to you if you make them free or mildly rewarding, but like you said, when you get to the point of paying people to take rides they would not have otherwise wanted to take, no-one's going to do it for a price that would make it competitive with the trucks.

Devor posted:Do you mean a W3-3 as shown on this link? Yeah, it was the orange W3-3. They made a 2-lane road into a 4-lane divided with no other major changes that spring to mind. They didn't even shift lanes, just added one to each side and pushed the turn lanes one further out.

sleepy.eyes posted:Not sure if this is the place, but why might a construction zone have an orange sign for a stop light that was there for well over a decade and hasn't been changed in the least? Well, first... sleepy.eyes posted:They made a 2-lane road into a 4-lane divided... At the very least they will need to add signal heads...so yes, it changed. Second, it could be any number of reasons: - They may be changing the signal operation during construction. - They may be doing something that they fear would distract from or block sight of the upcoming signal. - They may be reinforcing that the signal will say in effect despite the changes to the roadway. - There may be a history of people running the light. - They may need flaggers in the intersection regularly and want people to expect to stop.

They're just a patent trolling company based in the mid-east (forget which country). That being said, this machine is actually almost reasonable compared to the other stuff they come up with. Everything from DEATH BEDS to machines to clear out cholesteral in arteries to quadcopters with enough firepower to level a military base (they really, really like quadcopters). Also, I love how they cherry pick Moscow. Moscow's far enough north that I'm fairly sure the issue with potholes isn't so much the standard Russian corruption (though it probably doesn't help) but instead the old issue of water freezing to make potholes. Potholes which generally aren't worth properly patching until the weather warms up again.

Hence the little disclaimer. The innovation as such doesn't look terrible, at least apart from the circular saw bit. Thanks for the enlightenment!

Surely there must be a way, given a fixed gopro watching an intersection to count pedestrians moving through a given space (crosswalk). Also Cichlidae, I'm working at a Regional Planning Agency and twice now have used my knowledge of the MUTCD from this thread to win an argument. I don't know if this is good or bad.

Elendil004 posted:Surely there must be a way, given a fixed gopro watching an intersection to count pedestrians moving through a given space (crosswalk). There's companies you can hire that will go out, install a camera (either attached to existing infrastructure like traffic signals/lighting, or big free-standing tripod with giant pole) and then process the video into vehicle and pedestrian counts. I don't think they do computer-based counts for pedestrians, since it's harder to count groups of people that will be overlapping each other on the video, compared to discrete cars. And you'd have to spend a lot of effort back-checking the work anyways. But I think the computer-based video processing for vehicle movements is there in practice at this point.
