GOOGLE地圖點知交通情況

我一直都好奇
點解地圖可以有實時路況
紅色代表擠塞, 綠色代表暢通呢d野
到底google係用衛星監測全港道路
定只係憑經驗靠估

咪就係收集緊用戶電話既GPS數據囉

正解

咁如果果條路上冇車有smartphone但又塞車點算？

有咁多如果我發左達啦

都幾難出現呢個機會
多車自然有唔少用緊GOOGLE MAPS
即使冇開GOOGLE MAPS, ANDROID BACKGROUND LOCATION照拎到,除非所有ANDROID USER都BLOCK GPS,但機會好低

我諗唔係 Google map, 應該係 Google account 果個咩 “位置分享” 選項

高德地圖都好準

好多人用高德？

位置分享? 連登仔係唔係真係咁天真
你授權。係for俾你自己睇返。
你唔授權，係for佢自己睇and分析數據
拿。憎大陸還憎大陸。用得手機就已經係冇私癮。
我寧願裸體俾美國佬1個睇，但我唔會裸體俾美+支那2家睇。

有時高德仲on9過google

我都有諗過, 不過我係諗佢用GPS 訂位, 而唔洗開Google Maps

假設我塞車, 我係GPS個定位就會係慢慢/停左係到
Google對比數據suppose條路係行緊70km/h 而我GPS移動既速度低過70就會開始變橙色
當然係雖然某個地同一時間有大量人都係差唔多咁慢/停係到

我曾經試過揸車, 明明條路係鮮紅色, 但係行得都算順暢
所以我覺得Google Map 未必完全準, 佢只係用大量既population 去predict 當然既情況

利伸9up

Google Traffic works by analyzing the GPS-determined locations transmitted to Google by a large number of mobile phone users. By calculating the speed of users along a length of road, Google is able to generate a live traffic map.[2] Google processes the incoming raw data about mobile phone device locations, and then excludes anomalies such as a postal vehicle that makes frequent stops. When a threshold of users in a particular area is noted, the overlay along roads and highways on the Google map changes color

google都幾on9，上次去黃大仙廟，google水尻我去到鑽石山

你就真係on9...名都打錯
試下seach黃大仙祠睇下啦

應該係有用google acc login + 開gps
google就會分析data

衛星邊有可能

鬼唔撚知咩 我打”黃”，google已經出晒suggestion，我宜家只係懶，用iphone打個”黃”，出”大仙廟”，唔信自己試下

其實啲SUGGESTION 好鬼煩
商場地圖又煩

我自從上年年尾買左s8+就係咁
之前用iphone都冇
係咪而家所有新android機都係咁

條路冇車又塞車 你噏乜鳩
