The mission of the Mobility & Infrastructure Commission is to provide an integrated approach to the development, design, construction, and maintenance of the City's infrastructure systems that supports an exceptional quality of life in a sustainable manner.

Urban environments also require attention to multi-modal traffic flows (vehicles, pedestrians, bicyclists, buses) that move at different speeds and with different priorities. Our work in this area has led to the development of the Surtrac (Scalable URban TRAffic Control) system. Surtrac treats traffic signal control as a decentralized online planning process. Every few seconds each intersection constructs and begins to execute a signal-timing plan that optimizes the movement of locally sensed traffic through the intersection.
