Department of Mobility and Infrastructure

Mission

The mission of the Department of Mobility and Infrastructure is to provide the physical mobility necessary to enable the social and economic mobility of the people of Pittsburgh through the management, design, improvement and operation of the public rights of way.

Departmental/Bureau Overview

• The Department of Mobility and Infrastructure is responsible for all aspects of transportation and city- provided mobility services, including:
• Planning transportation and mobility systems, corridors, and network operations
• Managing the flow of infrastructure funding
• Developing policies to guide the use of public right-of-ways and management of transportation systems
• Managing the public right-of-way to ensure continued safe, efficient and productive use that respects and implements city policies and public priorities
• Designing, operating and maintaining the transportation system for safe and efficient mobility of all modes to sustain and grow a vital, thriving, and equitable Pittsburgh
• Designing and implementing street and other infrastructure improvements in collaboration with community and public stakeholders
• Measuring and monitoring mobility performance with the goal of continuous learning and improvement The Department of Mobility and Infrastructure (DOMI) is comprised of four bureaus: Planning and Development Review -
• Planning - Oversees development of system plans and multimodal networks and collaborates on implementation; develops conceptual design of transportation facilities; gathers and analyzes data on the condition and use of the mobility system; coordinates with county and regional organizations and entities to plan transportation infrastructure improvements and mobility systems; and serves as the initial point of contact for public stakeholders and partners for general mobility concerns or initiatives. Additionally, the planning division tracks development of the regional Transportation Improvement Program (TIP), development of the department’s submission to the city’s Capital Improvement Plan, and pursuit of grants and other resources to support implementation of the transportation program.
• Development Review - Reviews transportation and right-of-way elements associated with a proposed development or redevelopment in close coordination with the Department of City Planning and the Department of Permits, Licenses, and Inspections. Identifies the impact(s) of proposed developments on the transportation network and recommends improvements and transportation demand management strategies to mitigate impacts through transportation engineering and planning. Policy and Permitting - The Planning, Policy and Permitting Bureau is led by the Assistant Director and establishes the comprehensive vision, guiding policies and permitted uses of the urban mobility network and public rights of way. It is comprised of two divisions:
• Policy - Develops, communicates and maintains policies for the use, management, design and oversight of public mobility services, transportation facilities and public rights of way; manages demand on the mobility system; and develops and maintains guidelines, standards, and processes for the use of public rights of way and the operation of the system and mobility services.
• Permitting, Inspections and ROW Coordination - Issues permits for use of or activities in the public rights of way in compliance with regulations and established policies; coordinates current and future activities with public and private utilities occupying the public rights of way; and enforces right of way use to ensure all activities in the public right of way are in compliance with established rules and regulations and the Pittsburgh Code via the inspection process. The Permit Division coordinates the activities of utilities in the public right of way to minimize disruption and optimize opportunities for cooperative improvements.

Project Design and Delivery - The Project Design and Delivery Bureau is led by the Chief Engineer. The Bureau is responsible for all of the major capital improvement projects for transportation or mobility infrastructure. This includes not only street and bridge work, but also providing engineering services to address major slope failure and flood control needs in the city. The Bureau is comprised of five divisions:

• Bridges and Structures Division - The Bridges and Structures Division manages structural assets in the right-of-way including bridges, steps, and retaining walls. This work includes repair design, capital planning, and implementation of capital rehabilitation and replacement projects from design through construction. The division performs or contracts for condition inspection of structures in the public right of way to ensure the safety of the traveling public.
• Streets Division - The Streets Division manages city streets, sidewalks, and trails that comprise the city’s transportation network. Streets Division engineers manage preliminary and final engineering for complex public infrastructure projects and construction services provided by City contractors. The Division supports the Permit Division through review of restoration or alteration of the public right of way carried out by private developments. Project Managers develop and maintain standards and specifications for construction in the public right of way.
• Paving Division - The Paving Division oversees City resurfacing projects on public streets, trail facilities and other public paved surfaces and the improvement of sidewalk ramps affected by this work. The Division is responsible for resurfacing dozens of miles of streets every year in the city.
• Construction Division - The Construction Division of the Department of Mobility and Infrastructure addresses immediate needs for typically smaller scale improvements of infrastructure in the public rights of way. The Division oversees work to repair, replace or rehabilitate curbs, sidewalks, curb ramps, steps, walls, slopes and other similar projects. Division managers respond to emergency events that disrupt the safe operation of the mobility system such as landslides, sink holes, and bridge strikes.
• Bridge Maintenance Division - The Bridge Maintenance Division performs routine maintenance and small repairs using in-house staff for the city’s inventory of 145 bridges. The division also oversees and inspects bridge repair work performed by city contractors. Traffic Bureau - The Traffic Operations Bureau is led by the Municipal Traffic Engineer and oversees the operation of the overall transportation and mobility network. The Bureau includes four divisions:
• Traffic Design Division - The Design Division develops design standards and guidelines for transportation facilities including travel way dimensions, assemblage, operation, markings, signage, and other components. The Division is central in the determining design of facilities for vehicles, bicycles and pedestrians. It provides programmatic guidance for complete street, safe routes to school and traffic calming improvements.
• Signal Design Division – The Signal Division is responsible for designing the programming and operational plans for more than 600 signalized intersections throughout the city and designing plans for other devices such as school zone signs, rapid flash beacons, variable signs, and other elements. The Design Division assists the Planning Bureau in reviewing land development projects and specifically evaluating transportation impacts and necessary mitigations.
• Signs and Markings Division - The Signs and Markings Division fabricates, installs, repairs and/or replaces pavement markings, and signage. It is responsible for striping more than 2,000 miles of long markings, 10,000 marked crosswalks, and 850 traffic control and curbside regulatory signs. The Signs and Markings Division is typically responsible for the implementation of designs generated by the Design Division.
• Traffic Control Division - The Traffic Control Division performs necessary and routine maintenance on more than 10,000 traffic signal heads and other electronic traffic control devices across the City to keep them in operation. The three Bureaus of the Department of Mobility and Infrastructure are collectively responsible for:
• 1,060 linear miles of streets (890 asphalt, 90 concrete, 80 brick/block stone)
