Terse Directions

Adding to the discussion as to whether online maps’ directions are too exhausting, Tim Bray argues for terse directions: “When I’m navigating an area I already know about, don’t give me turn-by-turn, just give me a short list of the streets to take.”

Right now, Google Maps insists on turn-by turn, with three warnings for each turn. It’s dumb and annoying and interrupts whatever music or show I’m listening to.

What I want is to get in the car and say “Short directions to New Brighton Park” and have it say “Take Main to 12th to Nanaimo to 1st to Renfrew to McGill.” Then when I’m driving, I’d get one vocal warning a block out from each turn, like “Next left on Nanaimo” or some such.

‘Map-Splaining’

Modern online maps have so much data under the hood, and provide an overabundance of detail, that they can’t help but bombard the user, The Atlantic’s Ian Bogost argues, coining a term for their “sheer exhaustiveness”: map-splaining. It’s a challenge to take all that data and make directions comprehensible.

The maps know that one road is five lanes wide and the other six; both have medians. They understand that right turns between the streets can be accomplished via dedicated merge lanes that skip the red light. They appreciate that two lanes allow left turns between each of these streets, facilitated by a left-turn-arrow traffic signal. Having all this information helps the maps give their step-by-step instructions: Take the first turn lane from northbound 28th Street, then a quick right into the parking lot for Flatiron Coffee. That level of precision may be convenient for some drivers, but it comes at the price of breaking down the built environment into lots of extra segments and transitions that may trigger the display of useless routing information. Perhaps the software should just be telling you to “go past the light and make a left.”

Google Maps Sends Drivers into Nevada Desert After Interstate Closure

Last month, after a dust storm shut down Interstate 15 between Las Vegas and Barstow, Google Maps sent drivers off-roading, rerouting them via barely passable desert trails. Some were stuck for hours. Google has since apologized.

Jalopnik describes this as yet another case of blindly following, but I think this is a more specific failure mode. Rerouting due to road closures or traffic jams opens up routes that the algorithm would normally deprecate, and catches more drivers unprepared. It’s one thing when that means a quiet residential street gets an expressway’s worth of traffic, quite another when the second best choice is a dirt track—or a 500-mile detour. When the best answer the algorithm can give you is a bad one, it will still give you that answer.

Man Dies After Driving Across Collapsed Bridge, Family Sues Google

The family of a man who died after driving off a collapsed bridge is suing Google; they allege that despite multiple reports from users, Google Maps continued to mark the bridge in North Carolina, which partially collapsed in 2013, as passable, directing him and other drivers across it. The family is also suing local companies for failing to maintain the bridge or put up barricades and hazard warnings.

Online Map Roundup for January 2023

Apple Maps

Apple Maps now provides parking information for 8,000 locations in the U.S. and Canada.

Apple also launched Business Connect, a tool for businesses to upload their information to be used by Apple’s various apps: not just Maps, though that’s obvious (and something Google has been offering for quite some time: see James’s post for context). More at Ars Technica.

Google Maps

The first cars to get Google’s enhanced maps (previously), which include things like traffic lights and stop signs, will be the Volvo EX90 and Polestar 3, via Android Auto.

Meanwhile, turn-by-turn directions on Google’s Wear OS smart watch platform will no longer require a connected smartphone.

Online Map Roundup: Apple Maps in iOS 16, Google Maps Displays Tolls, Yandex Erases Borders

Apple Maps in iOS 16 will gain multi-stop routing, which I thought was a long-established feature on other platforms, as well as transit fare/card/pass integration. Apple’s new maps will also expand to more countries, and its detailed city maps will expand to more cities in the U.S., Australia and Canada. 9to5Mac has a summary.

As announced in April, Google Maps now displays estimated toll prices when routing.

Russian search engine Yandex is sidestepping the Russian invasion of Ukraine, frozen conflicts and other contested national borders by simply removing national borders from its map. It’s being spun as a pivot to local navigation. (Sure.)

TomTom Says Its Algorithms Avoid Potentially Dangerous Routes

It probably has nothing to do with Google redirecting traffic up poorly maintained mountain roads during a blizzard in California last month (previously), but TomTom has posted a piece explaining how its algorithms avoid sending drivers down potentially dangerous routes in Finland even though, on paper, they’re shorter.

TomTom’s routing and location technology recognizes that the shorter route to Koli National Park is on winding unpaved roads, made up of sand and gravel, and it takes that into consideration when computing a route for a driver. It places significant importance on this information. […] Even though the unpaved route is shorter, it’s still not considered “better” than the longer paved route when all things are considered. If map data didn’t include this contextual data about the specific road, the unpaved road would most likely be the default route suggestion.

Apple and Google Updates: AI Improvements, Airport Health Measures

Last week Google announced “over 100 AI-powered improvements to Google Maps” would be coming this year; these include bringing Live View indoors, a new air quality map layer, eco-friendly routing, and support for curbside pickup in business listings.

Meanwhile, Apple Maps is now displaying airport COVID-19-related health measures based on data from Airports Council International: press release. [AppleInsider, MacRumors]

99 Smartphones Create Virtual Traffic Jam

Simon Weckert created a virtual traffic jam in Berlin by pulling 99 used smartphones in a wagon: a large number of phones moving slowly looks like a traffic jam to Google Maps. “Through this activity, it is possible to turn a green street red which has an impact in the physical world by navigating cars on another route to avoid being stuck in traffic.”

Google’s statement to 9to5Google suggests that they’re taking Simon’s hack in stride: “Traffic data in Google Maps is refreshed continuously thanks to information from a variety of sources, including aggregated anonymized data from people who have location services turned on and contributions from the Google Maps community. We’ve launched the ability to distinguish between cars and motorcycles in several countries including India, Indonesia and Egypt, though we haven’t quite cracked traveling by wagon. We appreciate seeing creative uses of Google Maps like this as it helps us make maps work better over time.”

So people fed up with traffic being rerouted onto their residential streets could, conceivably, hack that traffic elsewhere—but not for much longer.

GPS Units: Still a Thing

Wirecutter’s Medea Giordano argues that even in the age of smartphones with built-in map apps, there’s still a place in your car for a dedicated GPS device: “there are cases when a phone just doesn’t cut it—say, in rural areas where coverage is questionable, or if you simply don’t want to drain your phone’s battery and data plan. Or when you’ve just found it frustrating to use a phone for long trips, like I have.”

‘You Are Blowing It’

Tom MacWright thinks that online maps are neglecting bicycle and multimodal routing at the expense of driving directions, which keep getting better.

Routing is the most powerful tool we have to reduce the environmental impact of driving, make cities quieter, safer, and more livable, and fight congestion. And you are blowing it.

This might be because HERE, the number two provider of map technologies, was bought by a bunch of car companies. Or because Google is headquartered in the suburbs. Or that the financial world is fixated on opening the pandora’s box of self-driving cars.

But the end result is the same: bicycle and multimodal routing continues to be a toy, and driving directions keep getting better.

This might well be about systems designed for in-car navigation first, or designed to replace them; or that are aimed at what is perceived to be the meat of the market. There are undoubtedly solutions out there that address Tom’s points, but there’s something to be said for having that solution front and centre in a mainstream service rather than having to find it in a less well-known app or a dedicated device.

Popular Mechanics Proselytizes Paper Maps

Popular Mechanics: “Even in 2019, there are good reasons to own a paper map, whether it’s the kind you can grab at the gas station or a sturdy road atlas […] that lives in your car.” This is a listicle, so six reasons are given, some of which are absolute rubbish: paper maps aren’t “nearly flawless” in terms of accuracy (they do go out of date), and they’re not inherently more comparative (checking vs. online maps) than checking one online map against another (e.g. Google vs. Apple vs. OpenStreetMap). Valid points about reliability and being able to plot out your own routes, though. [CCA]

A Mobile Mapping Roundup

Rerouting. Lifehacker talks about how to prevent mapping apps from rerouting you on the fly, and lists some options. [R. E. Sieber]

Traffic. Traffic congestion is a key feature of mobile mapping, and predicting it involves looking at historical data. CityLab reports on a recent study suggests that time-of-day electricity usage patterns can be used to predict traffic congestion patterns. A household that starts using power earlier in the morning gets up earlier and presumably will go to work earlier.) It’s another variable that can be put to use in traffic modelling.

Trail difficulty. OpenStreetMap doesn’t differentiate between “walk-in-the-park” trails and mountaineering routes, and that may have had something to do with hikers needing to be rescued from the side of a British Columbia mountain recently. The hikers apparently used OSM on a mobile phone app, and in OSM trail difficulty is an optional tag. The wisdom of using OSM in safety-critical environments notwithstanding, this is something that OSM editors need to get on. [Ian Dees]

Third-Party Map Apps Coming to CarPlay in iOS 12

As of iOS 12, coming later this year, CarPlay will support third-party map applications like Google Maps and Waze, Apple announced during its WWDC keynote earlier today: AppleInsider, Engadget, The Verge. Up until now the only maps available via CarPlay were Apple’s own; drivers who would rather use something else—and I know lots of them are out there—will soon have that option.
