Interdependencies across urban systems are increasingly acknowledged by city managers and planners. MAC focuses its research on utilizing data to understand the interdependency among three infrastructure systems, transportation systems, energy systems and water/sewer systems. The proposed research, if successful, creates a new paradigm for utilizing the complex nature of interrelationships among various urban systems to assist predicting and decision making.  At the same time, this research gains a better understanding of the interdependency of roadway, transit, parking and building systems, etc. through holistically mining the massive data of all those systems.
