| 摘 要： | 以原生质黏液菌觅食机理为理论基础,通过模拟黏液菌管道厚度随流量增大而增加这一生物智能,构建基于仿生学的区域交通自适应动态网络生长模型.以长江三角洲16个城市区域节点,模拟长三角区域交通网络从无到有、最终形成区域自适应运输通道的过程.仿真结果还表明,该模型可模拟区域交通网络随区域交通活动规模增大而复杂的发展趋势.

| Abstract: | This paper aims to develop a regional transportation network growth model based on the mechanism of Physarum connecting multiple food locations via a smart network.The mechanism involves the adaptation of the tubular body: a tube thickens with the flux.A mathematical model which contains a key parameter corresponding to the extent of the feedback regulation between the thickness of a tube and the flux is constructed to describe the tube dynamics.The adaptive transport corridor network growth for 16 cities in Yangtze River Delta was simulated by the model.The results show that the model can simulate the regional transport network growth;the proposed algorithm based on Physarum is simple and powerful. |
