MICROCOSPIC SIMULATION OF TRAFFIC IN NETWORKS: SUPERCOMPUTER EXPERIENCE

The results are given of recent computational experience with the NETSIM simulation model on a CRAY X-MP/24 supercomputer. The application of NETSIM to a large urban network is demonstrated, its computational performance on the supercomputer relative to conventional mainframes is compared, and the types of modifications to the NETSIM program that would be necessary to take better advantage of the parallelism present in the supercomputer architecture are identified. The paper reviews relevant background on supercomputing and CRAY, and the simulation experiments are described. Future modifications to NETSIM to enhance its performance in vector-processing environments are discussed, and comments are made on substantive questions in traffic theory and practical traffic problems that can benefit from enhanced computational capabilities.
