What if the map shows which roads are jammed and which are empty? Then surely a lot of time would have survived, right? To give him a chance, Google Map has come up with a live traffic update - it has been running in the developed world since 2008 but has been launched in Bangladesh recently.
To use it, click on 'Real Time Traffic' from the Map menu, go to the 'Traffic' option and select 'Live Traffic' from 'Typical Traffic'.

When the traffic option is turned on, you can see green, yellow, orange and red colors on the road on the map. If you see the green color, you will understand that there is no traffic jam on the road now. If you see orange color, medium traffic jam and red color, then you have to understand the traffic jam, and the latest maroon or, dark red means the highest traffic jam, it is better not to go by road :)

The question is which roads are jammed and which roads are empty - how does Google figure it out? Google uses "crowd sourced data" to find out. In other words, if the location service is turned on on the smartphones of the people who are driving on the road, then Google collects traffic data from them and makes an indicator. Through this, Google calculates the number of vehicles on the road and how fast the vehicles are running.
