ABSTRACT
This chapter describes a model of a bridge crossing and introduces the use of Discrete Event systems Specification (DEVS) and Cell-DEVS to model problems in traffic, one of the most popular applications of modeling and simulation. It discusses a model of a toll area on a highway and a junction between a highway and a route and a model of a traffic light controller. The chapter explores the traffic light controller with a model of the streets in the area, which are modeled using Cell-DEVS. It presents a multimodel of an urban city area and explains the Advanced Traffic Language Specifications traffic modeling language. The chapter analyses a simple model of a traffic controller for a bridge under repair, a toll station for a highway, the intersection of two routes into a highway, and various traffic light controllers. The traffic model represents a crossing on a bridge under construction. One way is blocked, allowing only one vehicle in each direction.
