There are numerous apps available on the market, such as Google Maps, Bing Maps, and Apple Maps. Google Maps is the most popular of these, and every cell phone vendor includes it as a standard feature. Google Maps is one of the most useful apps that has become a part of our daily lives and we are using it for free.

Google Maps suggests the best and alternate routes to the destination. There may be multiple locations to reach the destination, and Google tries to provide multiple possible routes to get there. It also provides live tracking of your path, indicating which paths have a lot of traffic and which do not. Google has used different color stripes to represent the traffic condition on the road in order to know and differentiate different types of paths.

How does Google collect those data?

Actually, when we first use Google Maps, it will ask us to agree to some terms and conditions, which we will accept without reading. In this case, it will say something like "Will access your location." Actually, here Google Maps is asking for permission to access the GPS, which we granted without reading those. From then on, your phone sends bits of data to the Google server in regular intervals, such as your location, your destination (latitude and longitude coordinates), speeds, and so on. So like you there might be many of us doing this.

As a result, Google Maps will have data from a large number of users and this helps Google to generate accurate real-time traffic conditions which Google Maps represents by various colors, turns by turns directions also provides the best alternative paths. This method of gathering traffic density we call it crowdsourcing as lots of information necessary for the crowd is gathered again from the crowd.

And Google Maps has both historical data and live data and results are generated by mixing those results. Google Maps combines all data generates useful information needed for you with various color lines on the road layer.

Why Google Uses Different Color?

Google Maps typically provides travelers with an estimate of the road's congestion level, calculated from the current speed and free-flow travel speed, which assists them in better planning their trips and navigating the roads.

Now let's discuss various road colors used in Google Maps.

In general, if you do not have traffic mode enabled in Google Maps, you will only see two color codes on the map, namely white and yellow.

  • Yellow: Generally represents highways.
  • White: For others local streets and roads.

Colors on Traffic Maps

Depending on the traffic situation, you will see different colors on your roads for traffic maps. The most commonly used colors in Google Maps are green, orange, red, and gray. Likewise, different color contrasts indicate clear, moving, slow-moving, or heavily congested traffic. 

1 Green Color:(No Traffic)

If you have a green color overlay upon your existing maps then it shows no traffic on the way. There is no congestion on the road and can travel freely on the way.

Green lines on the map indicate that vehicles on the road are moving at a faster rate around 50 miles per hour or more.

2 Orange/Yellow Color: (Moderate Traffic)

If you have an orange color overlay upon your existing maps then it shows there is a moderate amount of traffic. Everyone is moving too slow but not stopping. This might be due to road conditions and traffic lights.

Orange lines on the map indicate that traffic is moving at a faster rate, ranging from 25 to 50 miles per hour.

3 Red Color: (High Traffic)

If you have a red color overlay upon your existing maps then it shows there is a high amount of traffic and vehicles are moving very slow or stopped. If it has darker red color then it indicates there is more heavy traffic than the general red color.

The dreaded Red Lines on the map indicate that the traffic is moving at the slowest speed like less than 25 miles per hour or stopped.

4 Dotted Red Color 

Dotted Red color in the path indicates the road is color. Along with the path, there will be a stopped sign showing the road is closed.

In road signs, a red circle with a white horizontal line means "Do not enter." It might be there is an accident on the way or long-term construction work is going on.

5 Blue Color:(Low traffic/No Traffic)

If you search source and destination and want to travel via vehicles then you will in general see the path with blue color overlay upon existing maps.

Some light blue color is also used which provides an alternative path to reach the destination. This alternative path may take longer than the previous blue color.

6 Dotted Blue Color
If you choose walking as your mode of transportation, your entire route will be shown as a series of blue dots.

7 Grey Color(Alternative Route)

This path might be guessed from Google. They may represent alternative routes that usually will be longer in distance and/or in time. If you see gray lines, that means there’s no traffic information available at the time.

These all information is based on traffic status.

Now let's look at Map view.

  • Orange indicates interstate highways.
  • Yellow indicates state highways county parkways.
  • White indicates local and private streets.
