PARALLEL TRAFFIC FLOW SIMULATION OF FREEWAY NETWORKS, PHASE I

Numerical methods for solving simple macroscopic traffic flow continuum models have been studied and efficiently implemented in traffic simulation codes. The Lax method is an explicit method which has been implemented to solve simple continuum models in the traffic simulation package KRONOS. In this part of the project, the implementation of the Lax method for solving a high-order flow conservation traffic model was studied on parallel computers. An experimental code was written in C to simulate a freeway traffic flow. Tests with real data collected from the I-35 W freeway in Minneapolis were conducted on a workstation computer. The high order Lax method was then implemented on a parallel machine and tests were run with real data collected from an 18 mile stretch of the I-494 freeway. The parallel implementation demonstrated significant execution time speedup.
