Transportation corridors are an economic geography phenomenon in many countries. The development of corridors is strongly path dependent in space and continued over the course of time. The concept of corridor has been widely applied in urban or regional planning to guide the form of spatial structure. A good growth regional transport network will further improve and promote regional and urban spatial structure formation. This paper aims to develop a regional transportation corridor network growth model, which is based on the mechanism of physarum connecting multiple food sources via a smart network. The mechanism involves the adaptation of the tubular body - a tube thickens as the flux through it increases. The mathematical model contains a key parameter corresponding to the extent of the feedback regulation between the thickness of a tube, and the flux through it is constructed to describe the tube dynamics. Adaptive transport corridor network growth for 16 cities in the Yangtze River Delta is simulated using the model; the results show that the model and algorithm can simulate the regional transport network growth adaptively.
