The ultimate goal is not to reduce "traffic" (however you define it), the goal is to produce dense, livable cities that don't require car ownership in order to live. The reduction in car-related negative externalities is merely one happy side effect of this.

The bike lanes mentioned above all, by physical necessity, come at the expense of cars, either by reducing parking lanes or reducing driving lanes. Even if there were the same amount of traffic, fewer cars would be on the road because there is less road to be on.
