What speed does Google Maps assume when it generates estimated times for car routes?
Google Maps uses a combination of data sources to estimate the time it will take to travel a car route. These sources include:
- Historical traffic data: Google Maps collects data on traffic conditions from a variety of sources, including GPS data from users' phones and traffic sensors. This data is used to create a historical database of traffic patterns.
- Real-time traffic data: Google Maps also collects real-time traffic data from a variety of sources, including traffic cameras and sensors. This data is used to update the historical database and provide users with real-time traffic information.
- Road geometry: Google Maps knows the speed limits and other road conditions for all of the roads in its database. This information is used to calculate the estimated travel time for a car route.
Google Maps also takes into account the following factors when estimating travel times:
- The time of day and day of the week: Traffic conditions can vary significantly depending on the time of day and day of the week. Google Maps takes these factors into account when estimating travel times.
- The weather: Traffic conditions can also be affected by the weather. Google Maps takes into account the weather forecast when estimating travel times.
- The type of road: The speed limit and other road conditions can vary depending on the type of road. Google Maps takes this into account when estimating travel times.
The default speed that Google Maps assumes when it generates estimated times for car routes is 60 miles per hour (96 kilometers per hour). However, this speed can be adjusted in the Google Maps settings.
