Why are transit villages often built around existing mass-transit lines?

Transit villages are strategically developed around existing mass transit lines to promote high-density residential and commercial growth that reduces dependence on private automobiles. By situating these developments astride established transit networks, planners can effectively encourage sustainable travel patterns and minimize the land consumption and congestion typically associated with urban sprawl.12

This approach is favored by environmentalists because it leverages existing infrastructure to facilitate access to employment and services, thereby supporting the economic and social health of the community while lowering energy use and air pollution. By concentrating activity near transit, these villages resurrect historical urban planning models that prioritize efficient, transit-oriented movement over the sprawling, car-centric development patterns common in many modern regions.13
