Combined Evolution of Self-organization and Hetero-organization of Urban Traffic System

摘要: 城市交通系统发展演化是自组织与他组织复合作用的发展过程,各子系统之间非线性相互作用(表现为协作与竞争)是系统演化的本质动力.选取道路网容量与交通量作为序参量构建了城市交通系统自组织与他组织复合演化模型.模拟结果显示,管理部门的不同引导控制强度对应小汽车、公共交通和混合交通3种交通发展模式,不同交通需求与供给增长率对应供需追随型、引导型和超前型3种交通供给模式.Abstract: The evolution of an urban traffic system is a combined processes of self-organization and hetero-organization,and the non-linear effects(cooperation and competition) between the subsystems are the essential driving forces for the evolution of the urban traffic system.A combined evolution model for self-organization and hetero-organization of urban traffic systems was proposed,in which the capacity of road network and traffic volumes were taken as parameters.Simulation results show that different control degrees cause different evolution results: private car,public transportation and mixed traffic structures,and different development speeds of traffic demand and supply result in different development models of traffic supplies: following,guiding and over-demand models.
