Play as You Go: Virtual Solutions for a Real World

This article looks at developments in microsimulation modeling, noting that Intelligent Transportation Systems (ITS) strategies in particular have pushed the need for more complex software. It profiles a number of products, such as Paramics, which takes historic or current traffic data and uses it for predicting the impact of proposed changes. The article discusses how modeling approaches are evolving, particularly through the use of meso (which capture high-level dynamic traffic phenomena in large areas) and micro (which capture details of full dynamics in smaller areas) techniques. Dynamic traffic assignment (DTA) software, which uses path calculations, path flow rates estimation, and network loading, is also described. Other software products that are discussed include AIMSUM, CONTRAM, VISSIM. Included in the article is a sidebar which discusses the role that the Federal Highway Administration (FHWA) has had in the development of traffic simulation models.
