Match shows the percentage to which each route meets the following criteria: traffic, climbs and type of surface.

The Match score can be easily compared to help you choose your preferred route. 

The green-orange coloring used to show Match on your chosen route helps you understand better each part of the route. Green is part of the route that is a perfect fit for you, orange is part of the route that might be slightly different from your set preferences. (increased traffic volume, steeper climbs)
