Real-time traffic simulation of the german autobahn network

摘要

This work is part of our ongoing effort to design and implement a traffic simulation application capable of handling realistic problem sizes in multiple real-time. A 16-CPU SGI Power Challenger offers real-time for the whole German Autobahn network. On a workstation cluster we have reached multiple real-time for the Autobahn network of the state Nordrhein-Westfalen. In this paper we present the parallel architecture and techniques used in our implementation. We also given an upper-bound estimate for the scaling behavior of this type of simulation.
