ABSTRACT The article discusses the interplay of normative and temporal dynamics in agent-based traffic simulations (ABM). From a media-historical perspective, it focuses on the TRANSIMS simulation system as a seminal example for an ABM ‘mindset’ in transportation and infrastructure simulation. ABM explicitly links traffic simulation with the broader focus of mobility studies by connecting the mere physicality of transport dynamics with a sociality of agents claiming to be descriptive of real-life structures. First, TRANSIMS elevates the examination of traffic dynamics to a meta-level of urban infrastructure design where individual timing and purposeful agent behaviors are placed at the heart of traffic systems. Second, TRANSIMS provides a ‘virtual testbed’ by generating traffic scenarios which eventually lead to situations that meet certain normative limits or regulatory guidelines. And third, ABM often display a strong tendency towards a methodological individualism which requires a ‘theory guidance’ by disciplines like sociology, media theory, or political science to challenge the oftentimes oversimplifying parameters of their ‘artificial sociality’. Consequently, with regard to the scope of mobility studies, ABM can be understood as a medium which negotiates conceptual and interdisciplinary differences and thereby transcends the solely pragmatist notion of ‘virtual testbeds’ as unmitigated optimization tools.

交通寿命:基于代理的交通模拟中的时间动态和监管维度

摘要本文讨论了基于代理的流量模拟(ABM)中规范和时间动态的相互作用。从媒体历史的角度来看,它着重于TRANSIMS仿真系统,作为运输和基础设施仿真中ABM“思维定势”的开创性例子。ABM通过将单纯的运输动力学物理特性与声称描述真实生活结构的特工社交联系起来,将交通仿真与流动性研究的更广泛关注紧密联系在一起。首先,TRANSIMS将交通动态的检查提升到城市基础设施设计的一个元级别,其中将个人时间安排和有目的的行为作为交通系统的核心。第二,TRANSIMS通过生成交通场景来提供“虚拟测试平台”,交通场景最终导致满足某些规范限制或法规准则的情况。第三,反弹道导弹通常表现出一种强烈的趋向于一种方法论上的个人主义的趋势,这种趋势要求社会学,媒体理论或政治学等学科提供“理论指导”,以挑战常常过于简化其“人造社会性”的参数。因此,关于流动性研究的范围,可以将ABM理解为一种协商概念和跨学科差异的媒介,从而超越了单纯的实用主义的“虚拟测试台”概念,将其作为不受约束的优化工具。ABM常常表现出一种倾向于方法论上的个人主义的趋势,这种趋势要求社会学,媒体理论或政治学等学科提供“理论指导”,以挑战常常过于简化其“人造社会性”的参数。因此,关于流动性研究的范围,可以将ABM理解为一种协商概念和跨学科差异的媒介,从而超越了单纯的实用主义的“虚拟测试台”概念,将其作为不受约束的优化工具。ABM常常表现出一种倾向于方法论上的个人主义的趋势,这需要社会学,媒体理论或政治学等学科提供“理论指导”,以挑战常常过于简化其“人造社会性”的参数。因此,关于流动性研究的范围,可以将ABM理解为一种协商概念和跨学科差异的媒介,从而超越了单纯的实用主义的“虚拟测试台”概念,将其作为不受约束的优化工具。
