Mockup of NYC Bikeshare

Following on from yesterday’s post about the forthcoming New York City bikeshare, I’ve created a mockup of how the scheme might look like on my Bike Share Map. The mockup uses the most popular locations voted for by people on the NYC DoT website. It scales each docking station size by the number of votes received, and pseudorandomly decides how empty or full each docking station is, based on the initial time of the suggestion and whether or not the suggesting person said they worked near there. It’s set so that stations near where the person said they worked are more likely to be full – hence the cluster of full stations in Lower Manhattan and Midtown, while much of Brooklyn’s stations are quite empty.

There is a clickable, zoomable version here – I’ve tried to keep to the published boundaries of the scheme. It shows 585 docking stations (announced target 600), and 9802 bikes (target 10000), with a total of 20988 docking points across the stations. Every suggested docking station that had at least five votes as of a couple of hours ago, has been included.

This is a scheme that will have twice as many bikes as London, in an area only around 50% bigger – and there’s more water in the area. So the density of stations does look higher. The average size of each station (35 docking points, assuming roughly 2.2 docking points for each bike) is also around 50% bigger than London’s (23 on average).

New York City Bike Share – Details Revealed

It’s been announced today that the Alta Bicycle Company will be operating the huge New York City bike-share that will be likely launching next summer. An informative press release reveals the area of the scheme, which will be slightly larger than London’s existing area, but with roughly twice as many bikes in the system and 50% more docking stations, it will have a slightly higher density of available bikes and stations than here in London. The bike and dock design is likely to be very similar to London’s so will be very familiar to anyone visiting from across the pond – it’s also the same system used in Montreal, Washington DC/Arlington, Minneapolis, Boston, Toronto, Ottawa and Melbourne.

Interestingly the system will be financed entirely privately. I’m sure this will be an immense challenge, as London’s capital and operating costs are high. However London has demonstrated that advertising can be a very good deal for the advertiser concerned if the scheme is a success. (London’s planning overhead and so capital expense is also almost certainly higher than New York’s.) The scheme will run 24/365. NYC gets some pretty intense snowstorms in the winter, but so does Washington DC’s scheme, which also runs throughout the year – with occasional suspensions when it gets really bad.

NY will doubtless be looking to London closely, as it probably is the scheme most similar to New York’s – the same technology, roughly the same size and area (all of the US and Canada’s schemes are much smaller) and London’s topography is also quite similar – a major river bisecting the scheme, a single major business district (although London will cover two with next year’s extension to Canary Wharf) with a separate commercial centre, and a very large public park. Doubtless NY will see huge popularity for the bikes in Central Park on weekends, as London does in Hyde Park, and a big morning “commuter surge” from Brooklyn into Lower Manhattan, just like London’s from the Waterloo area to the City.

Interestingly the proposed area extends deep into Brooklyn, but on Manhattan Island it extends only up to 79th Street – roughly a third of the way up Central Park. I would be surprised if, on scheme launch, there aren’t some docking stations in Central Park that don’t in fact go north of this line. New York’s density and road layout structure means there are ample opportunities for the scheme to grow in the future, too.

Two websites have also gone live – Alta’s NYC Bikeshare has some nice mock-up pictures of the bikes (from which I’ve stolen the above pic) + an NYC Dept of Transportation website allows you to pick where you would like to suggest a docking station.

Very pleased to see a link to my bike map from the Alta site. With both big operators in North America (B-Cycle and Alta) being tacitly supportive of third-party maps such as my own – a big constrast to continental Europe – and the station data format likely to be the same, I have high hopes that we will see the plethora of mobile apps, maps and visualisations from the community expand to cover NYC.

N.B. The map above is my own estimate based on the press release boundary mentions. The final scheme on launch will not necessarily match these boundaries.

A Topologically Correct, Geographically Insane Tube Map

I’m a sucker for alternative maps of the London Underground, and here’s a great one – the Twisted London Underground Map by Francisco Dans (see the original in high-resolution on Flickr) – it’s perhaps not going to be useful to navigate by, but is a great bit of art.

A recent trend of alternative maps is to show geographically accurate ones, that inevitably end up crumpling the dense centre of the network and leave huge gaps on the edges. This is a map does the opposite – it has taken the geographical deformity of the underground network map to its (il)logical extreme. The real map has never pretended to correspond to the actual locations of the stations on the surface, placing stations in roughly correct locations, but only relative to each other and not the map as a whole. This does away with that rule too. But importantly, it is a topologically accurate map – the official connections are shown correctly. Everything else is curves of various radii – only the Underground logo and the station connectors are straight lines.

Francisco writes on his posting that he is looking to add in the DLR and Overground lines to a future iteration, plus fix a couple of bugs with the existing map that eagle-eyed observers have spotted. Hopefully the Thames will go in too, it’s the one non-tube feature that everyone loves. I wonder what that will end up looking like?

Thanks to Francisco for permission to reproduce the map and to IanVisits on Twitter for the heads-up. Cross-posted from the Mapping London blog.

London Riots Maps

James Cridland has created and is updating a map of verified reports of looting and rioting in London – and elsewhere.

I much prefer this to another map which is automatically updated from postcoded tweets (similar to the UK Snow map) as Twitter is as much a source of disinformation as information, particularly for emotive subjects like this (false rumours propagate just as quickly as true news) and also information that is not relevant – the cluster around Tottenham for example is by-and-large relating to offers of assistance rather than reports of trouble.

I’ve combined James’ data (as at 3pm today) in KML form, with a choropleth map from the London Profiler showing London-only deciles of the 2004 Index of Multiple Deprivation (IMD), and overlaid both on an OpenStreetMap map, using MapTube. You can see this here. Please note I’m not suggesting there is any correlation or causality between the IMD and the locations of the disturbances.

The riots have affected me slightly, in-so-far as it is difficult to find any supermarkets in north/east Zone 2 (i.e. inner-city London) open in the evenings, and I’m taking a long way round to home, via Tower Hamlets rather than Hackney, to avoid a couple of flashpoints on the way (and going home during daylight hours.)

Bike Sharing in France – Tours, Angers, Paris

I was in the Loire region of France last week for a holiday. Unusually for me, a “proper” holiday – no international orienteering racing or mountaineering. Instead, a chance to be a real tourist, visit les châteaux and try a bit of the local grape-based drinks.

…but France is rather advanced when it comes to bike sharing systems and I came across three of them:

Tours – Velociti

A traditional free-floating scheme rather than a dock-based one – members take one of the bright yellow bikes (below) and then lock it up whereever, when they are finished. I didn’t see anyone using them, but did spot them locked up in a few places, including one outside the train station and a few in a quiet square in the town.

Angers – Velocite+

Angers has apparently had a free-floating one for a long while, called Velocite – I didn’t spot any of these. But I did spot this seemingly brand new extension – Velocite+. There is only one (very large) docking station, right outside the train station. The docking station had Every dock was taken with a bike – presumably if there is only one docking station in a scheme, this is not a problem. The fee (effectively three euros for up to five hours) means people could feasibly hire one out at lunchtime and use it several times in an afternoon, before returning it back to the single docking station, rather than make short station-to-station hops. No sign of it being used yet.

Angers has also just launched its rather innovative tram – in the historic central section it uses radio-activated sections of electric third-rail, rather than unsightly overhead wires and gantries.

Paris – Velib

On the way back home, I had a day in Paris, and what better way around than by Velib? After spending much of the day around the canal area in the north-east and Sacre-Coeur, I headed into the centre (during the evening rush hour), then around to the Louvre, Notre Dame, and back up to Gare du Nord.

I managed eight journeys in all, and even got the bonus 15-minute credit for having dropped off a bike on the hill near Sacre-Coeur.

The OBIS Project

I was in Prague at the end of last month for the final OBIS Project meeting. OBIS was a multi-year European Commission project to study and document bike sharing systems in 10 countries in the European Union.

The project’s handbook was presented at the conference, and there were a number of talks from various cities on their own schemes, as well as some external speakers. I found the Barcelona one, given by the operator, particularly interesting – it focused on the difficulties they have with redistributing enough bikes to a densely populated part of the city with narrow streets. By switching to a hub-and-spoke model, they were able to significantly improve the effectiveness. London was covered by the CTC (Cyclists Touring Club) who presented on Transport for London’s behalf. The project actually covered the UK before London’s Barclays Cycle Hire launched, so focused on the smaller schemes in, for example, Cardiff and Blackpool. However London did make it into the final handbook. Stockholm’s presentation touched on the logistical and political issues there, particularly as regards finding space for docking stations – their scheme is therefore still at just 50% of its planned size/density.

Other sessions had insights into the differences between station-based systems and “leave whereever” schemes. The old Berlin system, which is just being switched to station-based docking, used to allow bikes to be left at any crossroads in the scheme area – fine in principal but Berlin has a very large number of crossroads.

As an external speaker, I presented on visualising bike shares around Europe and throughout the world, mentioning my own Bike Share Map as well as introducing some more complex work being carried out by others in the research lab here. I also went into detail on the excellent range of data available for the Capital Bikeshare in Washington DC, and touched on Hangzhou’s huge system, and London’s new official API. A slide from the presentation is above, I’m not posting the whole presentation yet though as it contains some forthcoming work from others here.

The session that launched the handbook outlined some interesting insights from it. It is useful to class European cities as “warm” or “cold” (p31 of the report.) Warm cities generally have two peaks in bike share usage a year – spring and autumn – it being too hot in the summer for mass usage. Cold cities peak in the summer, and often drop off completely in the winter and snow and ice takes over.

European countries were also categorised according to the cycling culture there – it is probably fair to place Germany in the top category, but I was somewhat surprised to see France in the middle one and the UK in the bottom one. Cycling in London has improved a lot over the last few years – even if transport planners insist in putting the cycle lanes on the roads and not the pavements – in fact I spent most of yesterday cycling in Paris – blog post to follow – and felt there were fewer (non-Velib) cyclists around than in London. Talking of Paris’s Velib, one tidbit I didn’t know about until I read through the handbook (p.61) was that the operators in Paris run a barge (!) up and down the Seine, on which they fix Velib bikes and at the same time transport them to where they are most needed. Kind of like a French version of the Travelling Post Office.

Prague doesn’t have its own full scale bike share system (yet) and the “modal share” of cycling is much less in Prague than in many other European capitals. There is a very small trial bike share in the city, I didn’t spot it. There were hardly any bikes on the streets, at least in the central part of the city I saw, although the route along the riverbank was reasonably popular when I passed and has a dedicated cycle path. There is one thing better than London though. A photo of the riverside route is below – if this were London, the bollards would be in the cycle path rather than in the pedestrian lane.

Vienna: Previewing GEMMA

At State of the Map EU I presented a preview of GEMMA, my current UCL CASA funded project, focusing particularly on the OpenStreetMap Feature Highlighter, that will be one of our key data sources – it being an OpenStreetMap conference, I thought this would be of most interest to the audience. GEMMA is more than that though – it will both be a portal of content and created maps, and a mobile application for collection and viewing of data.

Unfortunately my talk clashed with a cartography talk but quite a few people were in my track and saw some screenshots of OpenStreetMap data being highlighted in GEMMA. I also talked about integration with other CASA data sources – GEMMA is a consolidation project to tie together a number of CASA products – and mocked up some examples, focusing on a need to understand more of the demographics of London bike-share cyclists, a current personal interest of mine.

GEMMA is a JISC-funded project that I am working on with Steven Gray. It’s one of the JISCGeo projects, and should launch this autumn. It has its own website and also a blog, where I go into more detail about the project. This is the first CASA project, I believe, to make significant use of OpenStreetMap, and its great that we are now able to take advantage of such a rich and expanding dataset.

Human Visualisation

One thing I noticed in Vienna, and passing through Brussels airport on the way home, was a number of “augmented reality” advertising displays, ones that detect people in front of them and then show that on their screens. In all the following, Steve Gray of CASA was the subject being visualised.

Here was the first I saw, at Wien Mitte S-Bahn station, where a special “performance” box was taped out on the platform alongside:

Then, at Vienna Aiport, they had a screen above part of a walkway, which augmented various “forest” animals with passersby. Rabbits and deer would appear, grazing on the “grass” when no one was passing. As people approached, the animals would disappear back into the undergrowth. Passing people on the screen left virtual “leaf trails”, while butterflies would occassionally land on their shoulders. Unfortunately my camera didn’t take a great picture, although you can see a butterfly on someone’s hair and some leaf trails here:

On changing through Brussels, a “heat scanner” showed passing people. This was beside a travelator, so your moment of fame was brief:

Vienna itself currently has a aural art installation from the Royal College of Arts. On walking through the Meccano-like sculpture, detectors would sense you and a nearby speaker would start playing a musical sound. Each detector had a different sound type, but they worked in harmony to produce a kind of song, changing as you and other people moved around:

Sadly, on our arrival into Heathrow, we were back to the regular non-augmented ad experience.

Vienna: On CityBikes and Bike Lanes

Following on from my previous post – another reason I was particularly pleased to be in Vienna for State of the Map EU, was that Vienna has a bike share system! CityBikes has been around since 2003, it is run by JC Decaux, a commercial operator, but the scheme’s running data is controlled by the city authorities, hence I’m able to include on my Bike Share Map. Obviously I had to have a go, particularly as the scheme is open to tourists with a credit card, and is only 1 euro for as many journeys as you need over 24 hours ever – as long as each journey is less than an hour.

Vienna’s scheme is quite a bit smaller than London’s – it’s spread over a similarly sized area, but the density of stations is much lower (around 20% of London’s), so some advance planning is needed – you don’t generally just come across a stand. Redistribution also seems to be less frequent – for example my local stand remained nearly empty through for the course of the entire trip. Nonetheless I was able to make all three planned trips on the CityBikes, a 100% success rate which London’s disconnected docks and failing keys can’t match.

On the Thursday evening that we arrived, Steve and I borrowed a couple of bikes from a stand right outside the U-Bahn station on the Nachtmarkt and used them to get to the pre-conference drinks which were a couple of miles away to the north. Sign-up took ages – requiring numerous button presses and a password to be entered three times. The paper map in the stand dispenser proved to be quite handy though. We eventually got onto the fantastic, dedicated cycleways which are sensibly built on the pavements rather than the roads in Vienna, and clearly and regularly marked with blue and white cycle roundels on the ground, where errant pedestrians are more likely to look. Vienna’s streets are generally wider than London’s, allowing for such facilities – plus the narrower ones are generally one-way for cars and two-way for bikes. We accidentally headed straight into the old town rather than along the outer ring-road, but then joined the inner ring-road and had a spectacular cycle past the Museum Quarter, Parliament and City Hall. Another missed turn meant we ended up cycling three sides of a square, but we made it eventually and docked with no problems. Our return was similarly indirect – the first stand was empty, then after getting the bikes, we took an unscheduled right turn and discovered that Vienna does in fact have hills. Steve’s bike also proved to be less than road worthy, with the chain slipping and the back wheel wobbling and threatening to come off…

It turns out that there are two generations of bikes currently in use in the system. The newer ones are noticeable in that they have three gears rather than none – geared higher than London’s scheme, allowing some decent speed to be gained. They also have more comfortable handlebars, rotary bells, differently profiled rear lights and strobe front lights. The frame is also slightly different, with a lower support to the back wheel. The gears alone mean there is a considerable advantage in getting one of the new ones. In the photo at the top, the bike on the left and the furthest one on the right are the new generation bikes, while the other four are older. There are also at least four liveries on the bikes across both generations – grey/red, blue, yellow and purple.

The bikes feel heavier than London’s (if that were possible!) and because of the low dip in the middle of the frame, they tend to want to fall over a lot when you stop to look at a map and stand up. Thankfully this is OK as, in Vienna, you are generally on the cycle paths on the pavements, and not the roads themselves.

“Hot docking” – cycling straight into the dock point (a favourite of London commuters) – is just about possible, but more difficult to do than London’s – you need to approach from the left side and line up confidently. Nevertheless we had a go.

Our final trip was more ambitious – four of us OSMers headed right through the old city, past the cathedral, and eventually into the more commercial part of the city, then underneath the huge Praterstern station and right up to the Danube. Here, there is a dedicated cycle track underneath the road bridge. The bridge is however quite a way beyond the area of docking stations, so the other cyclists around were on more serious bikes.

It took us quite a way to get out here – over an hour, but that only resulted in an extra 1 euro charge. On the way back, it started raining as we passed under Praterstern, luckily this was as we passed a large dock, so we finished our return on the U-Bahn.

Vienna: State of the Map EU

So – I was at the State of the Map EU (SotM) conference in Vienna last weekend – a European-focused conference on the OpenStreetMap project. I travelled with my colleague Steven Gray and presented some screenshots from the GEMMA project I am currently working on at UCL CASA – more about that in a later post. The two of us, and London OpenStreetMappers Shaun and Tom, stayed at the shiny new Wombat Nachtmarkt hostel which was convieneintly a few minutes walk from the venue at Vienna University of Technology (TU Wien). I was impressed that, on walking onto the university campus, my phone connected seamlessly to the Eduroam wireless network, based on my UCL credentials – a feat that was not managed in recent trips to more local academic campuses in Manchester and Imperial.

I was impressed with the number of people at the conference – over 200, which was larger than the global SotM conference I was at in Amsterdam two years ago. According to the stats, 2/3rds of people there were from the German-speaking diaspora (Germany, Austria and Switzerland) which demonstrated the clear demand for a SotM conference based here.

I mainly followed the “Tech” track at the conference. I was particularly interested to know about Mapnik Metawriters, which I’m looking to incorporate into some forthcoming Mapnik-based work. You know when you click on Google Map POI icons (not pins) and you get a tooltip with the name of what you’ve clicked on? It’s similar to that. Another highlight included Andy Allan with a tour of custom cartography of OpenStreetMap data. Andy’s cartographic-focused talks are always a visual feast. Unfortunately my own talk clashed, but I managed to make a quick exit after mine and caught the last bit of his.

Another interesting talk was ESRI’s launch of version 2 of their OpenStreetMap editor for ArcGIS – OSMEditor. Of course, you still have to have a copy of ArcGIS in order to be able to use a plugin – so the non-academic, non-commercial audience is unlikely to be using it. I was slightly surprised the presenter didn’t mention the $100 non-commercial licence that is now available for ArcGIS. The $0 price-point for Quantum GIS (which also has an OSM editor plugin) is still going to be unbeatable, but ESRI is certainly going in the right direction. Their engagement with OSM is not something I would have suspected a couple of years ago, it’s great to see them sponsoring and presenting at a conference like this. Of course, having the OSM layer a click away in ArcGIS as a background layer is a good win for them too. And they even let us call them “esri” these days! :-)

Muki Haklay gave an overview of his team’s completeness analysis for the UK OSM dataset over the years. We used to say we “are good enough”. Now we can say that, subject to qualifications, we are “as good as” some traditional datasets. There was also some similar research presented by Heidelberg University, which used hexagonal cartograms, which was an interesting change from grid squares. I should also mention Steve Coast’s keynote, which was a frank statement of the current state of play of the project – good in many places, but problems with the Australian community feeling disengaged and looking to split from the project were clearly top of his mind.

It was great to meet face-to-face with some major figures in the community – notably Frederick Ramm of GeoFabrik. I managed to sit beside him for half an hour at the conference dinner without twigging who he was. Frederick is one of the authors of the OpenStreetMap book that I reviewed – one of my comments was used as a quotation in the book’s advertising at the conference!

Henk Hoff from the OpenStreetMap Foundation was in fine form, with one of his “poster auctions” at the end of the conference. He also announced the winner of the free trip to the “father” SotM conference in Denver in September being Gregory Marler. Gregory won with his Rebecca Black-esque recording “Fly me to SotM” (I hope he doesn’t mind me saying that!)

The social side of the conference was excellent. Plenty of breaks for networking, and a conference dinner on the Friday night. This involved everyone getting a couple of specially hired 1920s wooden trams (or “Bims” after the sound their bells make) to a suburb of Vienna – via the grand ring-road, past the various palaces and other grand buildings – whereupon we took over most of a restaurant for an Austrian feast of Wiener schnitzel, meat loaf, sauerkraut, picked cucumber, and a dessert of apple strudel. A few resturant-brewery combinations were also visited during the trip – along with some most refreshing lagers, served in proper glasses with handles that make a lovely “clonk”. Vienna was very warm indeed, with a thunderstorm on the first night. It was also eerily quiet – the city is quite grand and spaced out, plus maybe many of the locals were on holiday to the mountains. Certainly the people we met were friendly. I should mention specially the conference organisers, which were flawless and ensured everyone was in the right place at the right time! The organisation of the conference and social events appear to go off without a hitch.

It was a great trip to see what’s going on with the OpenStreetMap development community, present some of our own work at CASA, and explore Vienna.
