Hank Software Features

Space limitations preclude a detailed description of the Hank architecture in this paper. The major features of Hank include:

• A database system for representing the topology, geometry, and logical attributes of road networks. The road geometric model is based on analytical representations of road segments congruent with design methods employed by civil engineers [7,2]. This facilitates the design and use of three-dimensional roads with super elevated curves and hills.

• A behavior programming language and run-time execution environment based on HCSM.

• A run-time scheduler that executes core simulation processes. This includes processes for behavior, dynamics, image generation, driver I/O, experimenter I/O, and data collection.

Hank does not include its own run-time graphics libraries. At present we use Silicon Graphics' Performer for image generation (an Evans and Sutherland version is under development). In addition, we do not provide scene database modeling tools. We currently create most scene database models using Multigen.

• Process Organization
