Transit-oriented land planning model considering sustainability of mass rail transit

With the acceleration of urbanization, the mass rail transit (MRT) is developing rapidly in China. However, some unsustainable problems are brought to many metropolitan governments, such as the expensive costs of MRT construction and operation, the incompatibility between MRT and its surrounding land use, the difficulty of MRT sharing the benefits brought by itself, etc. Therefore, for the sustainability of MRT, this research presents a transit oriented development (TOD) planning model of China. The paper put forward the objective functions and constraints of China TOD (CTOD) model and designed the algorithm of this multiobjective optimal problem. The problem is divided into two phases and parallel genetic algorithm is adopted. By these methods, the Pareto optimization solution set is searched so that it can offer some alternative land-use schemes. Taking the example of Dan Zhutou station of Shenzhen metro third line constructing, the land-use schemes in walking available scope of MRT station are designed considering MRT sustainability. The optimization results are alternative schemes of land-use type and land-use density in planned region, so that the land use can ensure the sustainable development of MRT.
