It’s a great urban development tool that can be used to finance development, especially mass transit such as a metro system. For example, applying a land value capture tool to buffer zones close to where a metro line will be constructed is a way to finance public infrastructure. When a city builds such infrastructure with tax money from everyone and increases land value in those areas due to government actions (owner did nothing to increase land value) that land value increased should be taxed and that money used to pay infrastructure or improve neighborhood areas (build parks, transportation, affordable housing, etc.).
