This article describes the laboratory backbone of the California Advanced Research Testbed (CART), which is integrated with an actual urban traffic network. The research laboratory is based at the University of California at Irvine (UCI) and has real‐time communication capabilities with several traffic‐control centers in Orange County, California. We discuss a simulation and optimization environment that provides the capabilities to study various components of Advanced Traveler Information Systems (ATIS) and Advanced Traffic Management Systems (ATMS) in conjunction with the available real‐world connections. The platform accommodates system components such as communications, computing, modeling, prediction, optimization, and control with sufficient flexibility that different candidate system designs can be studied. The article focuses on distributed computing issues and implementation of the hybrid simulation framework that includes integrated microscopic and macroscopic simulation models.
