Just some Cincinnati-themed output from some work I’ve been doing recently… this is a map of the percent of streets, by length, which are dead-ends (for cars).
Data is from OpenStreetMap. The darker area on the map is defined by a street density of greater than 4km of roads per km2. The X and Y scales are in kilometers. Now a few other random cities for comparison. Smoothing was done with circular gaussian kernels with a standard deviation (bandwidth) of 2km.
Gosh. I’m going to do one of those academic blog posts where I self-promote by telling you that I’ve just published a paper and that you should go read it. I hate those. But, I had actually been meaning to make my thoughts into a blog post or two, and without the intervention of my academic advisor at the time, I would have; now the thing is a paper instead of a post, a full year after it would have been a post, and have I mentioned that you should read it? It’s about bike maps, and what I hate about bike maps and how I attempted to make them better as a genre, by example, and then by overly formal peer-reviewed explication.
Headsigns are trimmed and included. There is still some more cleaning to do though. Headsigns are quite inconsistent and I’m trying to just pull out prominent destinations.
Heading arrows have been dimmed and placed behind the text headings. These only show up after all of the shapes have loaded. Clearly, there are some legibility issues right now, but I think the positioning is the way I like it and legibility can maybe be resolved with color changes.
I’ve removed the randomly placed ‘vehicle locations’ that I’d been playing with. For now ;-)
Thoughts and comments much appreciated! If you follow the link above, you’ll be taken to a page where you can select stops. Pick one or a few and hit the button that says ‘use selected stops’. Then wait for something to go wrong and then tell me about it.
So, as you may remember, I’ve been tasked with developing a live display using SORTA’s real-time API. The basic idea is to put tablet computers around town in store windows, behind bars, on coffee shop counters, etc, which will alert people to the fact that there is a bus coming (they are almost always almost here) to take them where they might already plan on going. To that end I’ve been developing a web application that can run in a browser. When full-screened, it turns any monitor into a real-time display.
The tablets that we distribute to businesses will basically just have a link to the web-app stuck to their home screens. Which means of course that the tablets/laptops/typewriters y’all are using right now to read this can also function as a real-time display! Power to the people, I say.1
Well, development has been progressing more or less slowly over the last couple months (Did I mention that I graduated, got married (before it was legal!) and moved to another country? Well, I did. I’ve been busy.) but the app is finally ready to share as a beta version available at http://cincymap.org/rt/ .
To get started, pan to your location (or hit the button that asks for your location) and select some stops. For the love of jesus, make them close together; I didn’t design this for crazy teleporting people2. Then hit the button to use the selected stops and the app will load arrival times for those stops and start refreshing them when new data is available.
One of my big goals for this app is that it should help show people what’s available and where transit is actually going, not just when the obscure number X local is departing northbound, so maps are a big part of this. Right now, I have the app displaying the actual route on a background of OpenStreetMap tiles, with the portion already travelled diminished and the part yet ahead in a darker color. The map also has a bit of animation going on to highlight the whole remainder of the route before zooming back into the immediate context of the stop.
I’d appreciate any constructive feedback suggestions that anyone has, but please keep in mind that I’m still actively developing this. If you’re about to suggest something obvious, I’m probably about to do it anyway. Keep the suggestions subtle!
Goals for the next few days:
Modify stylesheets to allow for portrait oriented screens.
Find a tileset that I can use without bothering anyone. I’m pretty sure the OSM people will be a little peeved if I use the basic tiles in a production app. Something black and white perhaps?
Remove the route numbers from all but the first departures for each route. The colors can distinguish for the rest, or perhaps I can just make the number a lot smaller to allow a bit more map space.
Distinguish between arrivals that are real-time and those which are only scheduled. This shouldn’t matter once Gaslight makes an update to their API.
Give an indication of direction for each of the upcoming arrivals on the right side. This matters a lot for two-way stop selections, but it’s not super obvious how to do it technically in a way that will give intuitive results. I’m thinking something like this.
Goals for the next month:
Play with displaying vehicle locations when vehicles are off-screen. I’m planning to have this ready to present at the NACIS conference in Minneapolis this October. Right now I have the app generating random vehicle locations for the purposes of testing some ideas, until we get the vehicle locations API up and running3.
For those of you who may have missed an earlier post, or who are finding this blog for the first time, please be advised that there may be but few updates coming. I have moved away from my exciting and bitter eight-year relationship with Cincinnati to the more expensive and diverse city of Toronto, Ontario.
Still seen as through a cell phone, darkly.
Though having been here for several days now, I feel I should send a letter home with some initial thoughts and relevant comparisons.
I don’t yet understand how bicycling works here. There seems to be much more bicycle infrastructure, and about a thousand times more cyclists, but I still find myself quite definitely on the vehicular cycling side of the debate. Cyclists here ride far to the right side of the road, and while car drivers seem very much more competent at driving near people, they can still pass extremely close to the cyclists, even while they are riding in the door-zone next to parked cars. In fact, that appears to be the norm. Perhaps people are also extremely cautious about opening their car doors? As a vehicular cyclist myself, this sort of riding absolutely terrifies me. Yet a couple times when I tried to take the lane for myself, the car behind me clearly indicated that this was not how it expected/wanted me to behave. There are also clear benefits to filtering forward on the right: cars can’t turn until the pedestrians clear the crosswalks, but bikes going straight can get ahead of the turning cars by moving with the pedestrians.
Streetcar tracks are not as bad for bike tires as I thought they would be or as the ones in Cincinnati are. I think the Toronto tracks have narrower grooves and are more flush with the road.
There is actual bicycle congestion here, exacerbated to be sure by the fact that cyclists generally stick to a narrow bike lane. Passing is constrained by the presence of cars on the left, so a slow rider can hold up a line of bikes for a while. Also, cyclists actually pile up at red lights! That’s not interesting so much as it is exciting, I guess.
Can it be possible that Cincinnati has a slightly more modern fare payment system than Toronto?? This agency still has tokens and accepts cash fares at the point of boarding, and does not have a stored-value card1!
Streetcars travel down the middle of many two lane streets and people board them by walking to the middle of the street across a lane of traffic. But the traffic is extremely well-trained and will not pass a stopped streetcar until all of the doors are closed.
What’s the deal with the new streetcar designs TTC is rolling out? Are they supposed to be sexier? Flashier? To get all the “choice riders”? Hell no. They are clearly being introduced because they are larger and the smaller streetcar vehicles can get insanely crowded. There is a line in the Spadina subway station to get on the streetcar and they have to cut it off when it’s packed full. A larger vehicle…
Streetcar bunching and breakdowns are a major problem as far as I can tell. TTC operates some very long routes, and since the vehicles can’t pass eachother or anything else that gets in their way, all of the cars have to turn back before the breakdown until the thing is cleared. Streetcars have their charm, but this would not be a problem with electric trolley buses.
So, I think the big lessons from the first week are that it’s possible to train car drivers to be more competent around the humans, bike lanes do NOT ever make me feel more safe, and streetcars are definitely less reliable than buses.
That’s what I got for today. Now back to working on that real-time app!
