Microscopic traffic simulation with reactive driving agents

Microscopic traffic simulators can model traffic flow in a realistic manner and are ideal for agent-based vehicle control. In this paper we describe a model of a reactive agent that is used to control a simulated vehicle. The agent is capable of tactical-level driving and has different driving styles. To ensure fast reaction times, the agent´s driving task is divided into several competing and reactive behavior rules. The agent is implemented in and tested with a prototype traffic simulator program. The simulator consists of an urban environment with multi-lane roads, intersections, traffic lights, and vehicles. Every vehicle is controlled by a driving agent and all agents have individual behavior settings. Preliminary experiments show that the agents exhibit human-like behavior ranging from slow and careful to fast and aggressive driving behavior
