Traction is the grip that a tire, shoe, or foot has on a surface, which stops it from slipping - good winter tires give better traction on ice and snow. You can also use this word for ideas: when a new idea, product, or plan starts to gain traction, it means more and more people are finally paying attention to it, supporting it, and helping it succeed.
