Data Analysis plays a crucial role in Google Maps' traffic predictions. Google uses a combination of data sources to analyze traffic patterns, making it possible to provide accurate and up-to-date information.

GPS data from smartphone users is the biggest source of Google Maps' traffic data. This data is sent to Google when people turn on Google Maps on their phones and start driving, allowing Google to track location and movement speed.

Google also analyzes historical data to learn from past traffic patterns. This data shows when traffic is usually heavy in a particular area, such as during school hours or office rush.

Historical data is based on the average speed of cars on a road at different times and days, collected over many years. For example, Google Maps knows that the 280 freeway in Northern California typically has vehicles traveling at a speed of 65mph between 6-7am, but only at 15-20mph in the late afternoon.
