Sometimes there are many ways to get from point A to point B, whether you are walking or driving. Until now, Google Maps’ directions feature has given you the route they consider the best and allows you to drag and drop the route to change your path. Today, Google Maps is adding functionality that suggests additional routes so that you can see all of them on the map for comparison.
Under a “Suggested Routes” heading, you will now be able to access other routes to the same destination. This is a feature that GPS systems in car, like a Garmin device, have been offering for quite some time so it makes sense that Google would want to catch up. Google says that they choose alternative routes bases on many factors, including distance, travel time, and number of turns. Google Maps boils this data down to what is the lowest “cost” and ranks the routes based upon the “cost.”
MapQuest doesn’t suggest alternate routes but the site does let you choose alternate routes by filtering directions by no toll roads, highways, and distance, which is a function Google Maps has as well.
