Mobility & Infrastructure


The Mobility & Infrastructure Commission shall provide advice and recommendations to the City Council and staff on matters within the Commission’s scope and duties that have been referred to the Commission by the City Council, Mayor, or City Manager. The scope and duties of the Transportation, Mobility and Infrastructure Commission shall include:

  • Transportation Planning
  • Bicycle and Pedestrian Policies
  • Movement of Goods
  • Vehicles
  • Public Transit
  • Ridesharing, Transportation Network Services, and Taxicabs
  • Plans and Standards for Roads, Bridges, and Highways
  • Flood Management Infrastructure
  • Bicycle and Pedestrian Policies and Facility Planning

The Mission

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.

Planning & Analysis


Expected outflows from each intersection are communicated to its downstream neighbors to achieve coordinated behavior. Initial deployment of Surtrac in the East End of Pittsburgh has produced significant performance improvements and the technology is now starting to transition to other cities.

Current work with Surtrac focuses on using direct vehicle- (and pedestrian)-to-infrastructure communication to further enhance mobility, online analysis of traffic flow information for real-time incident detection, and integrated optimization of signal control and route choice decisions for vehicles receptive to receiving (re)routing guidance.
