The best bike maps are made by volunteers

Not all bike routes are equal. Some places that are marked as bike routes on a map feel precarious when traversed on two wheels, including shoulders covered in debris and places where you can feel the wind from speeding cars.

North American cities are building more bicycling routes, by adding on-street painted lanes, physically separated cycle tracks, bicycle-only or multi-use paths and local street bikeways. These different kinds of routes appeal to different types of users, from the interested but concerned cyclist to the keen road rider.

Despite this boost in biking infrastructure, a city’s website may not immediately reflect the changes or it may lack important information that can make cycling safer or more enjoyable.

Web-based maps that allow people to add information about bike routes give riders detailed data about the type of route, what it might feel like to ride there (do you have to ride close to cars?) and where it can take them (for example, shopping, work or school).

They can also tell us which cities are the most bike-friendly.

Measuring bike routes

We set out to assemble a dataset of bike routes in Canadian cities using their open data websites. But we found it was nearly impossible to keep it up-to-date because cities are constantly changing and the data are shared using different standards.

The solution was OpenStreetMap, which creates and distributes free geographic data. Anyone can add data or make edits to OpenStreetMap, whether they want to build a better bike map or make a navigation app.

We looked at OpenStreetMap data for three large cities (Vancouver, Toronto and Montréal) and three mid-sized cities (Victoria, Kelowna and Halifax) in Canada.

Not only did the data in OpenStreetMap agree reasonably well with the cities’ open data: in many cases it was more up-to-date. OpenStreetMap tended to include more local details such as where painted bike lanes ended and often marked the short cuts connecting suburban streets.

How did OpenStreetMap measure up?

Our analysis focused on how well different types of routes were mapped. We measured cycle tracks (which physically separate bikes from motorised traffic), on-street painted bike lanes (which use painted lines to separate bikes from motorised traffic), bike paths (which are located away from streets) and local street bikeways (which include traffic-calming features and where bicycling is encouraged).

Painted bike lanes are the most common type of route and also the most consistently well mapped. This makes sense, because the definition of a painted bike lane may be clearest across time and place. There is also a straightforward way for volunteers to tag it on OpenStreetMap.

But it was harder for us to distinguish cycle tracks from on-street painted lanes or paths (bicycle-only or multi-use) using OpenStreetMap. Local street bikeways were challenging to identify because of the wide range of ways cities design these kinds of routes along residential roads. Some use traffic-calming measures such as curb extensions, traffic islands, speed humps and raised traffic crossings to slow vehicle traffic and encourage safety, or greenery, reduced speed limits and bike-friendly markings on signs and the road surface.

Bicycle routes that are physically separated from motor vehicles and pedestrians, like cycle tracks and bicycle-only paths, have the greatest benefits for bicycling safety and encourage bike use.

Ease of access to bicycle routes is important to a city’s overall bicycle friendliness, but there are other important things to consider including the distance to destinations, the number, slope and length of hills, number of riders and how the transportation culture of a city can influence its safety.


Bike-friendly Canadian cities

Our results showed that Montréal has the greatest total distance in cycle tracks in Canada. As cities continue building more bicycle routes, researchers and planners can use OpenStreetMap to measure these changes on the ground.

The perfect bicycle map is up-to-date, covers the entire globe and gives riders an idea of the kinds of experiences to expect on different trails, roads and paths. People cycling in cities can contribute to the high-quality geographic data needed to understand changes in bicycle friendliness.

But OpenStreetMap is only as good as its contributions. The exciting thing is that anyone who wants a better bike map — city planners, researchers and everyday riders — can join the bike-mapping revolution by logging in to OpenStreetMap and mapping the features that are important to bicyclists.

London’s rail and tube map is out of control

Aaaaaargh. Image: Getty.

The geographical limits of London’s official rail maps have always been slightly arbitrary. Far-flung commuter towns like Amersham, Chesham and Epping are all on there, because they have tube stations. Meanwhile, places like Esher or Walton-on-Thames – much closer to the city proper, inside the M25, and a contiguous part of the built up area – aren’t, because they fall outside the Greater London and aren’t served by Transport for London (TfL) services. This is pretty aggravating, but we are where we are.

But then a few years ago, TfL decided to show more non-London services on its combined Tube & Rail Map. It started with a few stations slightly outside the city limits, but where you could you use your Oyster card. Then said card started being accepted at Gatwick Airport station – and so, since how to get to a major airport is a fairly useful piece of information to impart to passengers, TfL’s cartographers added that line too, even though it meant including stations bloody miles away.

And now the latest version seems to have cast all logic to the wind. Look at this:

Oh, no. Click to expand. Image: TfL.

The logic for including the line to Reading is that it’s now served by TfL Rail, a route which will be part of the Elizabeth Line/Crossrail, when they eventually, finally happen. But you can tell something’s gone wrong here from the fact that showing the route, to a town which is well known for being directly west of London, requires an awkward right-angle which makes it look like the line turns north, presumably because otherwise there’d be no way of showing it on the map.

What’s more, this means that a station 36 miles from central London gets to be on the map, while Esher – barely a third of that distance out – doesn’t. Nor does Windsor & Eton Central, because it’s served by a branchline from Slough rather than TfL Rail trains, even though as a fairly major tourist destination it’d probably be the sort of place that at least some users of this map might want to know how to get to.

There’s more. Luton Airport Parkway is now on the map, presumably on the basis that Gatwick is. But that station doesn’t accept Oyster cards yet, so you get this:

Gah. Click to expand. Image: TfL.

There’s a line, incidentally, between Watford Junction and St Albans Abbey, which is just down the road from St Albans City. Is that line shown on the map? No it is not.

Also not shown on the map: either Luton itself, just one stop up the line from Luton Airport Parkway, or Stansted Airport, even though it’s an airport and not much further out than places which are on the map. Somewhere that is, however, is Welwyn Garden City, which doesn’t accept Oyster, isn’t served by TfL trains and also – this feels important – isn’t an airport.

And meanwhile a large chunk of Surrey suburbia inside the M25 isn’t shown, even though it must have a greater claim to be a part of London’s rail network than bloody Reading.

The result of all these decisions is that the map covers an entirely baffling area whose shape makes no sense whatsoever. Here’s an extremely rough map:

Just, what? Image: Google Maps/CityMetric.

I mean that’s just ridiculous isn’t it.

While we’re at it: the latest version shows the piers from which you can get boats on the Thames. Except for when it doesn’t because they’re not near a station – for example, Greenland Pier, just across the Thames to the west of the Isle of Dogs, shown here with CityMetric’s usual artistic flair.

Spot the missing pier. You can’t, because it’s missing. Image: TfL/CityMetric.

I’m sure there must be a logic to all of this. It’s just that I fear the logic is “what makes life easier for the TfL cartography team” rather than “what is actually valuable information for London’s rail passengers”.

And don’t even get me started on this monstrosity.
