Abstract
This paper presents a first year report of an ongoing multi-year project to develop a systolic parallel simulation system for dynamic traffic assignment. The fundamental approach to the simulation is systolic parallel processing based on autonomous agent modeling. Agents continuously act on their own initiatives and access to database to get the status of the simulation world. Various agents are defined in order to populate the simulation world. In particular, existing models and algorithms were incorporated in designing the behavior of relevant agents such as car-following model,headway distribution, Frank-Wolf algorithm and so on. Simulation is based on predetermined routes between centroids that are computed off-line by a conventional optimal path-finding algorithm. Iterating the cycles of optimization-then-simulation, the proposed system will provide a realistic and valuable traffic assignment. Gangnum-Gu district in Seoul is selected for the target area for the modeling. It is expected that realtime traffic assignment services can be provided on the Internet within 3 years.
