How Google Recognizes Traffic Jams in Maps

Published

on

Berlin artist Simon Weckert recently “hacked” Google Maps by filling a red wagon with 99 iPhone running Google Maps and dragging around the city to fool the service into thinking there was a traffic jam when there wasn’t one.

It’s a clever trick, but it raises questions as to how Google Maps tracks and responds to the data it collects in normal traffic conditions. If it’s possible to fool Google Maps with a pile of old iPhones and a wagon, can you always be certain the app is accurate? Based on what we know about Google Map’s algorithm and the company’s responses to Weckert’s DIY traffic jam, the answer appears to be: yes, for the most part.

How traffic jams show up on Google Maps

Google Maps continually refreshes based on anonymously tracked user data, traffic sensors, and satellite data to make sure the app is displaying the most accurate traffic conditions possible.

If you’ve ever used Google Maps, you’ve likely seen streets colored green, orange, or red. Green roads mean traffic is moving normally, but orange and red represent slowdowns. Slowdowns show up when users in navigation mode are currently traveling at slower-than-usual speeds on that part of the road and are applied by Google automatically. However, once other divers using Google Maps are able to get through the area at normal speeds, Google will remove the slow down status for that area—even if other users are still driving slower.

It’s unclear how many slower-than-usual users are necessary for Google Maps to register it as slow traffic, but according to 9to5Google’s report on Weckert’s traffic jam experiment, it only took a single car driving past him at normals speeds to undo the traffic jam status caused by his wagon of iPhones. That said, it appears that Google Maps ignores when lots of users are at a standstill. Weckert’s wagon had to be moving in order for Google Maps to see the traffic jam—even though nearly 100 phones were in navigation mode and not moving. How long a vehicle must be idling before it’s ignored is unclear; obviously, Google Maps will notice if several users are stopped on a highway and report it as a slow down, but if a bunch of people are parked in a parking garage and just happen to have navigation mode on, then you probably won’t see any traffic jams listed in the area.

Interestingly, not all vehicles are treated equally. Google Maps can tell the difference between a car, motorcycle, and other vehicles (at least in certain countries and regions). So even though a cheeky scooter might be able to weave its way through a traffic jam, Google Maps could—in some cases—recognize that the smaller vehicle’s movement doesn’t necessarily mean that regular traffic conditions have resumed.

Accidents, construction, and other traffic incidents

Google Maps also updates traffic reports based on user input in addition to passive, anonymized location and movement tracking to help keep conditions updated.

Accidents, construction zones, speed traps, and other alerts can all be reported in Google Maps, and the more users that report an alert help it show up faster on the map for others and potentially help them avoid slowdowns and find better routes if necessary. We’ve previously covered how to do this on both Android and iOS, but here’s how to report traffic incidents and slowdowns in Google Maps if you’re unfamiliar:

  1. While in Google Maps’ navigation mode, tap the “+” icon (third icon down on the right-side menu).
  2. Tap the icon for the type of incident you wish to report. Follow the on-screen instructions to finalize the submission.
  3. The app will begin adding the report to the map, though you have a short countdown window to undo the report if you want to cancel.

Reroutes and ETA calculation

Google compares the speeds of its users with speed limit information to calculate estimated arrival times. Basically, it takes how fast you’re actually moving, how fast you should be moving based on speed limits, how fast other drivers are going and adjusts how, and how much further you have on your route to determine your ETA.

Google Maps will also cross-reference user-reported conditions and other traffic data is monitors with your route and current speeds, and will adjust your arrival times if it notices a slowdown or other incidents along your route. Once the app has determined the severity and length of the slowdown, it will alert users whose routes are affected and suggest alternative directions if it’s ultimately faster.

Google Maps’ reroute suggestions aren’t always perfect, however. The algorithm can only respond to the most recent data and make a guess—it certainly can’t tell the future, either—so rerouting won’t always be faster (or necessary). That said, you can be reasonably confident that the app is giving you the most up-to-date information it has.

iPhone 12’s four models compared: Differences between iPhone 12, Pro, Pro Max and Mini

Published

on

By

After a month-long delay due to the COVID-19 outbreak, Apple last week announced its latest family of iPhones during a virtual online event. The new lineup includes the iPhone 12, iPhone 12 Mini, iPhone 12 Pro and iPhone 12 Pro Max, and all feature 5G connectivity, a magnetic backing branded as MagSafe that can attach to a number of accessories and a new ceramic display that promises to be more durable. You can read CNET’s iPhone 12 and iPhone 12 Pro review here.

With so many devices, it can get a little confusing about what makes these handsets different from each other. In general, the iPhone 12 and 12 Mini are the two most affordable phones in the lineup and have dual rear cameras. The two Pro models are the highest-end and priciest iPhones. In addition to a third telephoto camera, they also have a LiDar scanner for modeling and object detection. (Here’s how and when to preorder all four iPhone 12 models at different prices.)

For a full rundown on the iPhone 12, take a look at the chart below, where you can see their specs side-by-side. And for more information on all of the iPhone news.

iPhone 12 vs. iPhone 11

Published

on

By

This month, Apple unveiled the iPhone 12 as the successor to the popular iPhone 11, with a new squared-off industrial design, the A14 Bionic chip, an OLED display, and MagSafe. As devices that are more affordable than the Pro models, but more fully-featured than the low-cost iPhone SE or iPhone XR, the ‌iPhone‌ 12 and ‌iPhone‌ 12 mini will likely be the most popular options for consumers.

The previous ‌iPhone 11‌ continues to be sold by Apple. As it is a year older than the most recent ‌iPhone‌ 12, it starts at $599, while the ‌iPhone‌ 12 starts at $799. As the ‌iPhone 11‌ and ‌iPhone‌ 12 share a large number of features, should you consider purchasing the older model to save money? Our guide helps to answer the question of how to decide which of these two iPhones is best for you, but overall the ‌iPhone‌ 12 is a moderate upgrade over the ‌iPhone 11‌.

Comparing the iPhone 11 and the iPhone 12

The ‌iPhone 11‌ and ‌iPhone‌ 12 share a large number of key features, such as display size and battery life. Apple lists these same features of the ‌iPhone 11‌ and ‌iPhone‌ 12:

Similarities

  • 6.1-inch Retina display with True Tone, P3 wide color, Haptic Touch, and a max brightness of 625 nits
  • A-Series Bionic chip
  • Dual 12MP Ultra Wide and Wide cameras with two times optical zoom range, Night mode, Deep Fusion, and optical image stabilisation
  • Face ID
  • Battery life with up to 17 hours of video playback
  • Aerospace-grade aluminum
  • Lightning connector
  • 4GB of RAM
  • Available in 64GB, 128GB, and 256GB
  • Available in White, Black, Green, and (PRODUCT)RED

Apple’s breakdown shows that the iPhones share a number of notable key features. Even so, there are meaningful differences between the ‌iPhone 11‌ and ‌iPhone‌ 12, including display technology, the processor, and 5G connectivity.

Differences

‌iPhone 11‌

  • LCD Liquid Retina HD display with 1792-by-828-pixel resolution at 326 ppi and 1,400:1 contrast ratio
  • 4G LTE cellular
  • A13 Bionic chip
  • Wide Lens f/1.8
  • Next-generation Smart HDR for photos
  • Water resistant to a depth of two metres for up to 30 minutes
  • Qi wireless charging
  • Available in White, Black, Green, Yellow, Purple, and (PRODUCT)RED
‌iPhone‌ 12

  • OLED Super Retina XDR display with 2532-by-1170-pixel resolution at 460 ppi, 2,000,000:1 contrast ratio, and HDR
  • 5G connectivity
  • A14 Bionic chip
  • Wide Lens f/1.6
  • Smart HDR 3 for photos
  • Dolby Vision HDR video recording up to 30 fps and Night mode Time-lapse
  • Front-facing Night mode and Deep Fusion
  • Ceramic Shield front
  • Water resistant to a depth of six metres for up to 30 minutes
  • MagSafe and Qi wireless charging
  • Available in White, Black, Blue, Green, and (PRODUCT)RED

Note that the iPhone 12 Pro provides a few improvements to the ‌iPhone‌ 12 in the areas of camera quality, LiDAR, RAM, and material design. Meanwhile, besides the size of screen and battery, the iPhone 12 Mini is otherwise identical to the ‌iPhone‌ 12.

Read on for a closer look at each of these aspects, and see what exactly both iPhones have to offer.

Design and Colors

The ‌iPhone‌ 12 has a new squared-off industrial design with a flat aluminum band around the sides. Both iPhones use aerospace-grade aluminum on the edges and a single piece of polished glass on the rear.

‌iPhone 11‌ vs ‌iPhone‌ 12

The designs are actually fairly similar, but with the ‌iPhone‌ 12’s edges being flat and the ‌iPhone 11‌’s being convex. The ‌iPhone‌ 12 represents a refinement, or what Apple calls an “elevation,” of the ‌iPhone 11‌’s design rather than a complete overhaul, but it does feel markedly more modern, and may well be more secure to hold in the hand. The ‌iPhone‌ 12 is also 0.9mm thinner and 32 grams lighter than the ‌iPhone 11‌.

Both are available in White, Black, Green, and (PRODUCT)RED, but each generation has some exclusive colors. The ‌iPhone 11‌ is also available in Yellow or Purple, while the ‌iPhone‌ 12 is available in Blue.

Display

The display is an area of major improvement for the ‌iPhone‌ 12. The latest model has an OLED Super Retina XDR display, compared to the ‌iPhone 11‌’s LCD Liquid Retina HD display. The OLED display offers nearly twice the peak brightness of ‌iPhone 11‌, significantly higher contrast and true blacks, HDR for richer colors, and systemwide color management for industry-leading color accuracy.

The new OLED display also features reduced bezels compared to the previous LCD model. By pushing the display further to the edges, the overall footprint of the device is slightly smaller. ‌iPhone‌ 12 also features stronger Ceramic Shield front glass, with up to four times improved drop performance.

The display improvements of the ‌iPhone‌ 12 are one of the main reasons to get the newer model. The ‌iPhone 11‌’s LCD Liquid Retina display is good but slightly dated. There is no doubt that the advances made with the ‌iPhone‌ 12 and OLED make for a much more attractive device.

A13 vs A14

Apple says that the A14 is “the fastest chip in a smartphone,” and is the first commercial processor to be built on a five-nanometer process. The ‌iPhone‌ 12 is roughly expected to be 18.4% faster in single-core performance and 17.6% faster overall in multi-core scoring than the ‌iPhone 11‌. For machine learning, the A14 Bionic features a 16-core Neural Engine, resulting in an 80 percent increase in performance.

A13 Bionic is still up to 20 percent faster than the A12, and the performance improvements of the A14 are not so drastic as to make the A13 feel slow by comparison. The A13 in the ‌iPhone 11‌ remains a very powerful processor that is capable of completing all day-to-day tasks fluidly.

5G Connectivity

The ‌iPhone‌ 12 comes with sub-6Ghz 5G, as well as faster mmWave 5G in the United States. 5G will deliver improved internet speeds for faster downloads and uploads, higher quality video streaming, more responsive gaming, real-time interactivity in apps, FaceTime in high definition, and more. ‌iPhone‌ 12 models also feature a new “Smart Data mode,” which extends battery life by intelligently assessing 5G needs and balancing data usage, speed, and power in real time.

The ‌iPhone 11‌ has the normal 4G LTE cellular connectivity that has been present in smartphones for many years, with no ability to connect to 5G.

In spite of its merits, 5G is only worth it if have an eligible data plan and are in an area with 5G coverage. If you are in an area with good 5G coverage or you intend to keep your ‌iPhone‌ for some years, 5G connectivity with the ‌iPhone‌ 12 may be important to you. As 5G is still in its infancy, the ‌iPhone 11‌ is still a good smartphone for its price without 5G.

Cameras Similar, Software Better

The cameras of the ‌iPhone 11‌ and ‌iPhone‌ 12 are similar. Both feature rear a dual 12MP camera system with an Ultra Wide and a Wide lens. The Ultra Wide lenses have the same apertures, while the ‌iPhone‌ 12 Wide lens has a slightly larger aperture (f/1.6) which offers better low-light sensitivity. They also both share the same 12MP f/2.2 front facing camera.

Features such as Night mode, Deep Fusion, and optical image stabilization are shared between the devices on the Wide camera, but the ‌iPhone‌ 12 extends Night mode and Deep Fusion to the Ultra Wide and front facing camera as well.

For video, the ‌iPhone‌ 12 can record HDR video with Dolby Vision up to 30 fps and time-lapses with Night mode.

For more significant camera improvements, you’ll need to step up to the new iPhone 12 Pro, which adds a third camera lens for telephoto capabilities, as well as a LiDAR scanner for improved autofocus and other features that rely on depth perception.

Battery and Charging

Both iPhones have a battery life allowing for up to 17 hours of video playback and can charge up to 50 percent in just 30 minutes with a 20W power adapter. Apple says that the ‌iPhone‌ 12 can achieve up to 11 hours of streaming video playback, instead of the ten hours of the ‌iPhone 11‌, but it seems that both models will generally perform similarly when it comes to battery life.

‌iPhone‌ 12 offers a unique charging feature, however. MagSafe improves wireless charging by easily aligning the charger with the internal coil via an array of magnets. MagSafe chargers can provide up to 15W of power while still accommodating existing Qi-enabled devices.

MagSafe also opens up possibilities for an ecosystem of magnetic accessories such as Apple’s new leather wallet, as well as a range of third-party products.

Other iPhone Options

Apple is also continuing to sell the ‌iPhone XR‌, which was the predecessor to the ‌iPhone 11‌, for $499. The ‌iPhone XR‌ shares the design and display of ‌iPhone 11‌, but uses an older chip, cannot use camera features such as Night mode, and has a single rear camera only. If you are on a budget or don’t need some of the ‌iPhone 11‌’s features such as the dual-camera setup, the ‌iPhone XR‌ may be a better option for you.

If you feel that ‌iPhone 11‌ or ‌iPhone‌ 12 does not offer enough high-end features, and are interested in more advanced photography and videography, improved AR experiences, and more premium materials, you may wish to consider the iPhone 12 Pro or the iPhone 12 Pro Max.

Final Thoughts

Ultimately, the ‌iPhone‌ 12 offers some clear improvements over the ‌iPhone 11‌ when it comes to the design, camera software, display, 5G, and MagSafe. While the improvements with regards to the camera hardware, processor, and battery life are relatively small, the addition of Night mode and Deep Fusion to the Ultra Wide and front facing camera of the Phone 12 could be significant for some customers.

5G connectivity, the OLED Super Retina XDR display, refreshed design, improved night photos of the ‌iPhone‌ 12 are the key features that differentiate it from the ‌iPhone 11‌. While the typical day-to-day experience of the device is probably not significantly different, the overall improvements push us to recommend an ‌iPhone‌ 12 over the ‌iPhone 11‌, budget permitting.

iPhone 12 vs. iPhone 11: Main differences, according to the buzzing rumor mill

Published

on

By

Apple is expected to unveil the iPhone 12 at its Oct. 13 event (tomorrow), and ship the new phones sometime in October or even November. If you’re thinking about upgrading from last year’s iPhone 11 to the iPhone 12, you may be wondering: What exactly is the difference going to be?

We won’t know for sure until the new phones are revealed on Tuesday. But we’ve gathered the most probable rumors to see how the iPhone 12 will likely stack up against the iPhone 11. You can also determine if you should buy a new iPhone now or wait, and the best ways to sell or trade in your old iPhone.

The biggest differences between the iPhone 11 and iPhone 12 will likely be the specs, of course. This is what we’re expecting from the iPhone 12.

Four iPhone 12 models

It’s possible that we’ll see four iPhone 12s launched on Tuesday: the iPhone 12 Mini (5.4-inch) the iPhone 12 and 12 Pro (6.1-inch), and the iPhone 12 Pro Max (6.7-inch). For comparison, there are only three iPhone 11s: the iPhone 11 (6.1-inch), the iPhone 11 Pro (5.8-inch) and the iPhone 11 Pro Max (6.5-inch).

Increased refresh rates

There is speculation that the iPhone 12’s display will have a 120Hz refresh rate and a ProMotion display, which you can currently find in the iPad Pro. Most phones (including the iPhone 11) refresh at 60 frames per second, or 60Hz, but some, like the Galaxy S20 and the OnePlus 8 Pro, refresh at 120Hz. The higher the refresh rate, the faster and smoother a phone feels when scrolling through apps and websites.

Better cameras

As is typically the case with new iPhones, you can expect the iPhone 12’s cameras to be upgraded over the iPhone 11. The iPhone 11 has a photo Night Mode and an ultrawide-angle camera that can add extra detail in photos, along with a great video camera. There have been rumors that the iPhone 12 may add a time-of-flight camera, like the Galaxy Note 10 Plus has, to help capture depth information. This could do a number of things like help with AR mapping, but could also mean you finally get the ability to have portrait mode in video.

The addition of 5G

One of the iPhone 12’s expected biggest new features is next-generation 5G cellular connectivity. Apple’s event invitation starts with “Hi, Speed,” leading us to believe that the new phones will finally get 5G connectivity, as virtually all new Android phones arriving in the US already have. This means the phones could tap into the high-speed wireless network on the go — which might seem slightly less exciting during the pandemic, as we’re spending more time at home, but will still future-proof your device for the rise of 5G.

The iPhone 11 does not offer 5G connectivity, though many people seem to believe it does.

Price

The 2019 iPhone 11’s base model cost $699, which was $50 less than the 2018 iPhone XR. It’s possible that this trend of lowering prices will continue: One tech analyst reports that the iPhone 12 base model (the Mini) will cost $649, the iPhone 12 Pro will cost $999 and the iPhone 12 Pro Max will cost $1,099. Here’s everything we know about iPhone 12’s price so far.
