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.

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.”

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.

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.

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’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.

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.

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.

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]

Why does Apple underpromise and overdeliver, while Waze does the opposite? Artur suspects it’s because Waze needs to monetize its app with ads, and Apple doesn’t:

For Apple, Maps is a basic solution for its average user who wants a maps solution out of the box. Apple Maps does not directly drive ad or subscription revenue for Apple so there is less reason for Apple to incentivize iOS users to use Apple Maps over other solutions. However, Apple does care about user experience, and sandbagging trip time estimates so that users arrive at their destination on time results in a great user experience. Hence, I believe that Apple is intentionally conservative with estimated arrival times.

At the other extreme, Waze (Alphabet) makes money through ads when you use their app. What better way to get people to use your navigation app than by over-promising short trip times when no one takes the time to record data and realize that you under-deliver? If an unsuspecting user opens Apple Maps and sees a 34-minute route and compares that to 30 minutes in Waze, the deed is done. Now Waze has a life-long customer who doesn’t realize they’ve been hoodwinked and Waze can throw at them stupidly annoying ads.
