Does google maps traffic update in real time

As a result, Google does not know the origin or destination of your trip. Google also has algorithms that can exclude anomalies like a postman stopping more often on a route to deliver letters. These algorithms will find out and exclude the such cases. Thus a frequently stopping postman will not trigger a traffic congestion alarm in Google Maps. Once Google gets enough data to make an opinion about the traffic situation on a road, it begins painting.

If the traffic is going smooth on a road, Google Maps paint the road with green color. Slow traffic is marked with yellow color and traffic jams are indicated by red color. Severe traffic jams are indicated by deep red maroon color. When Google does not have enough data about traffic conditions on a road, it offers you to show the typical traffic on that location at that particular time.

This tells us that Google saves the traffic conditions on roads in its database and use this information as a learning tool. Yes, there is a privacy concern involved in this approach of data gathering. Google knows a lot about us. Nevertheless, Google has provided an option to opt-out and not share your location related data with Google. So, this is the secret behind the mind-boggling traffic update feature of the Google Maps. I hope you like this article. Please feel free to share your viewpoint on this topic.

Note: Notice the warning at the bottom of the map. Google Maps automatically provides information that may make travel difficult in a certain area such as weather. You will see a detailed traffic analysis of the current time and place on the main map view. There is a color legend at the bottom, but essentially, green roads are okay for traffic while orange and red show congestion or heavy traffic.

If you set a start and destination, your route options will also show these colors to give you an idea of what to expect.

However, Google automatically chooses the fastest route. Another great function for smooth travel is knowing when you should travel. But today, Google will give you the busiest times for nearly any roadway based on an average of congestion. From here, you can see the busiest times to travel the roads Google Maps suggests to get you safely to your destination.

So under these circumstances, Google Maps will show 6 minutes delay. Factors Behind High Accuracy. So now that you have understood how the app shows you traffic information, it is quite obvious to extrapolate that the more people using the app, the more accurate the traffic data will be.

But if say a hundred people travelling on the same road do that simultaneously, it will very much affect the accuracy. Apart from that, Google also keeps a track of your navigation history. This data is mainly used to determine the shortest path and which path would have the least traffic at a particular time.

Then suddenly this number drops to 0. In such scenario, it concludes that there is something wrong with the path or it is temporarily closed and it automatically switches to an alternate route, shows the longer path if needed. To give more accurate information, it continuously monitors the traffic patterns shows you the approximate time based on that data.
