Does that mean taking away car lanes and parking spaces for better public transportation, better bicycle paths and better pedestrian paths?

In some cases, yes. But the best bike lanes are the one’s that are away from any traffic at all.

Seoul demolished a freeway to make way for more public transportation and more green spaces. The city has attracted affluent and educated workers and residents who appreciate the feel of a natural environment in an urban setting, open watercourse handles flooding rains better than buried sewers, highway led to the transformation of nearby streets and brought a 3.3 degree Celsius drop in average summer temperatures in the area and boosted Seoul’s tourist economy [1][3].

There are some more other examples where tearing down highways created better living experience for all [4]. Rochester, New York is in the process of removing a freeway and they see a revival in the city [5].

Furthermore, there is a study that no-car zone helps in a highly congested cities. A group of computer scientists created a software to know which streets to close [6].
