Precision Systems, Inc. provided traffic signal design services for the DC City Center
Featured Projects
Citywide Alley Inventory and Assessment System
PSI developed a new approach to alley maintenance planning to support Washington, DC’s AlleyPalooza repair program. PSI devised a novel semi-automated data collection method using computer software and field instrumentation, and an interactive QA/QC module, in order to provide significant time and accuracy improvements in the assessment of physical condition of alley assets. PSI created a scoring system and maintenance priority and cost estimation system based on the results.
Citywide ADA Inventory and Compliance Priority System
PSI supported Washington, DC’s ADA compliance and pedestrian accessibility efforts by developing an asset inventory and planning tool for pedestrian infrastructure. PSI’s novel semi-automated data collection method greatly accelerated the field inspection work, while PSI’s streamlined data entry program and parsimonious data definitions simplified the population of the inventory. PSI developed a multifactor, objective prioritization method for ADA accessibility issues and a financial planning tool. The ADA system was the subject of a presentation at the 2019 Transportation Research Board (TRB).
Citywide Traffic Engineering Design
PSI provides quick turnaround on diverse task orders aimed at addressing high-crash-hazard locations across Washington, DC. These have included multimodal transportation facility design, traffic studies, spot intersection improvements, MUTCD warrant studies, traffic calming, traffic signal design and signal timing, and other engineering tasks.
Traffic Signal & Streetlight Design for Walter E. Washington Convention Center
PSI designed the traffic signal and street light systems for the Walter E. Washington Convention Center in Washington, DC. PSI handled the challenges of designing underground conduit on roadway that was cantilevered over an underground parking garage, leaving a complex configuration of utilities in limited space and requiring manholes and passways between pavement decks. PSI also developed signal modifications for the construction phase, including over 40 intersections.
Union Station/Columbus Circle
PSI redesigned the traffic signal and street light systems for Columbus Circle at Union Station. PSI coordinated closely with all stakeholders, including National Park Service, Architect of the Capitol, District Department of Transportation, and Federal Highway Administration, to create an electrical system design to support the lights and signals. PSI also coordinated with the civil engineer to reconfigure the roadway and bus access routes in front of Union Station.
Buzzard Point Soccer Stadium
PSI designed pedestrian and vehicular traffic signals, street lights, and accompanying equipment and underground infrastructure for the new soccer stadium construction project in Southwest Washington, DC. PSI coordinated with nearby projects such as the Frederick Douglass Memorial Bridge to ensure traffic signal timing reflected anticipated traffic volume changes.
Embassy Row Reconstruction
PSI completed a traffic study, concept development, and civil design for 0.8 miles of Massachusetts Avenue, N.W. in Washington, DC including Sheridan Circle. PSI designed multimodal transportation infrastructure improvements, traffic signal and street lighting modifications, pedestrian and bicycle safety upgrades, and green infrastructure. PSI’s design emphasizes tree cover, ample pedestrian lighting, and modern streetscape that preserves the boulevard’s history and Beaux-Arts aesthetic.
PSI developed TARAS2, a software-as-a-service program used by government planners and engineers to address traffic safety issues proactively. TARAS2 automatically connects with police crash data and audits data for improved consistency and reliability using machine algorithms that mimic engineering judgment. TARAS2 provides modern, interactive web-based tools for geospatial and tabular analysis of crash data patterns at both executive level and detailed crash information. TARAS2 analyzes crash patterns to make automated safety recommendations.
PSI is providing civil design for a major electrical power line undergrounding effort in Washington, DC, covering 37.1 miles of cable and 27.5 miles of conduit trench. PSI is several months ahead of schedule thanks to efficient project management and coordination with all stakeholders to expedite survey and permitting, while ensuring high-quality designs are produced quickly by efficiently allocating resources.
14th Street, N.W. Corridor Improvement
PSI’s context-sensitive design covered one mile of 14th Street, N.W. from Thomas Circle to Florida Avenue in Washington, DC. PSI designed the roadway, traffic signals, street lights, and streetscape including bioretention and stormwater management, ADA accessibility upgrades, and pedestrian safety measures. PSI designed the first bus-bicycle islands in DC to prevent conflicts at intersections between buses and bicycles, while preserving curbside access at midblock locations along this vibrant mixed-use corridor.
Kennedy Street, N.W. Improvement
PSI provided civil design for this roadway and streetscape rehabilitation of one mile of Kennedy Street, N.W. from Georgia Avenue to North Capitol Street, and Missouri Avenue & Kansas Avenue in Washington, DC. PSI designed ADA-compliant streetscape including extensive coordination with local business and many grade-change concerns. PS included innovative green infrastructure including suspended pavement and bioretention planter boxes, and traffic calming measures such as curb extensions and raised crosswalks.
