how does the abbe know there's a traffic

jam ahem

according to a recent study more than

50% of all smartphone users in the u.s.

rely on GPS navigation apps I'm stunned

again and again at how precisely they

display current traffic conditions they

can even predict how long my trip will

take amongst countless providers Google

Maps is the one that does the best job

at least that's what many people think

but how exactly does the app work the

answer sounds rather simple Google Maps

collects data that's what the company

does is their business model and they

collect a lot more data than their

competitors - but where do they get the

data how can they predict traffic

conditions and what role do I play as a

user take a look there are a bunch of

GPS navigation apps on the market like

Apple maps ways or here they all offer

traffic information and they all rely on

user data but when it comes to numbers

there's a clear number one a staggering

41% of Internet users worldwide use

Google Maps that's about 1 billion

monthly users and nearly 30 percent of

all Google searches to be able to use it

on a mobile phone hundreds of millions

of people around the world give Google

access to real-time data it's collected

from iPhones that have Google Maps open

or from Android phones that have

location services turned on the phones

anonymously sent data bits to Google

Google then uses this vast amount of

information to analyze traffic and road

conditions with all their computing

power the company is able to determine

the total number of cars and how fast

they're going on nearly any road

worldwide at any given time compared to

its competitors

Google's advantage is the sheer number

of people who use it and therefore the

amount of data Google obtains in the US

for example 67% of all smartphone users

trust Google when it comes to navigation

that's about 6 times more people than

the next most popular app Google Maps

doesn't stop at informing about the

current traffic

situation the program also makes

predictions about how traffic will

develop throughout the day to be able to

do that Google has put together a

traffic history over the last few years

it's a database that knows what traffic

is usually like on specific roads at

specific times that's how the app can

predict how traffic will change during

your drive just because there's traffic

200 kilometres ahead of you now doesn't

mean it will still be there when you get

to that point right so we already know

Google follows every single person that

is using the Maps app but the company

also relies on another precious source

Google Maps incorporates traffic data

from Waze a popular navigation app with

more than 90 million monthly users

worldwide in addition to what Google

Maps does ways has another way of

gathering data the app gets information

directly from users who report accidents

or traffic jams it goes without saying

that this is priceless knowledge for

Google probably we're worth the 2

billion US dollars that the companies

spent for buying ways in 2013 the

database of traffic history information

enables the app to alert you if traffic

is better or worse than it typically is

and also to predict how accidents and

slowdowns

will affect traffic on different roads

in different parts of the world just to

be clear I use Google Maps a lot it's a

very convenient service and it keeps

getting better and better but at what

cost

to make it work you are giving away a

lot of information according to Google

the location data you're sending is

anonymized so it should be worthless in

terms of refining your user profile and

selling targeted ads still the problem

as I see it is this Google is at the

forefront in nearly any field of online

map services just think of Google world

and Google Street View and if you want

to use map service commercially they

come with a price tag

google has a huge advantage and by using

the services we have the company to

leave their competitors like Apple maps

even further behind how can we avoid

that it's rather simple just switch off

location services on your phone that

should prevent Google from accessing

your location but if everyone did that

then one of the best Google Maps

features wouldn't be working as well as

it does now I

handle the situation like this I only

turn on location services when I really

need them that way at least I don't give

away my personal data all the time what

do you think do you use Google Maps or

do you prefer other navigation apps let

us know and if you have a question on a

digital topic let us know as well down

here in the comments hope you enjoyed
