Development of Integrated Meso/Microscale Traffic Simulation Software for Testing Fault Detection and Handling in AHS

In this report, we describe the research carried out under PATH Task Order 4208. The objective of this project was to bridge the gap between the Automated Highway System (AHS) simulators SmartAHS and SmartCAP, by implementing an integrated AHS micro-meso simulation environment for analyzing a large-scale AHS network. In fulfillment of this goal, a meso-microscale traffic simulator was developed that allows a stationary region of microsimulation to be defined within a larger, mesosimulated AHS. This simulator permits analysis of traffic behavior in situations where both vehicle-level (microscopic) and aggregate-flow (mesoscopic) effects are important, while avoiding the prohibitive computational cost of microsimulating a large-scale AHS. The accomplishments of this project, including the development of the meso-micro batch compiler, user interface, and a manual traffic extension to SmartCAP, are detailed in this report.
