Comprehensive Transportation Corridor Layout of Urban Agglomeration Based on Improved Ant Colony Algorithm

摘要

The comprehensive transportation corridor layout of urban agglomeration affects the operation of various modes of transportation and the exertion of their comparative advantages and comprehensive benefits. In order to give full play to the role of agglomeration and diffusion of transportation corridor, reduce transport cost, and meet the needs for close internal and external connection, the generation method of comprehensive transportation corridor in urban agglomeration was studied. After influence factors and nodes analysis, a transportation corridor layout algorithm based on ant colony search is designed and implemented with the importance degree of links as the basic heuristic condition. The probability of next node selection in searching is not only determined by the pheromone and the connection importance to adjacent nodes, but also the guidance of the terminal node. An example shows that the application of the method is effective, which is conducive to the construction of perfect and reasonable layout structure of comprehensive transportation corridor in urban agglomeration.
