Spatial cooperative scenario simulation for infrastructure siting in Guangdong-HongKong-Macao Greater Bay Area.

Siting transportation infrastructures such highway and highspeed railway connects cities and benefits the coordinate development in urban agglomerations. Previous infrastructure siting models rely on the expert experience or spatial-support decision using spatial data describing current conditions. The future development after the infrastructure construction is less considered. This study presents an alternative spatial cooperative simulation-based infrastructure siting model. The spatial cooperative scenario simulation model is developed to simulate the land, population, and economy variations and assess the benefits of the infrastructure construction. The experiment in the high-speed railway in Guangdong-Hongkong-Macao Greater Bay Area, China demonstrates the effectiveness of the presented model. The results provide valuable insights into the spatial-support siting decision for the new high-speed railway in the urban agglomerations.
