Each year, the Town will select three artist proposals to cover three designated traffic signal boxes. This will be an annual contest in which 3 new proposals will be chosen each year, for a total of 20 wrapped boxes when it is complete.

Artists should submit a digital design that can be converted to a digitally printed wrap. Only digital submissions will be accepted. The winners will receive a certificate, in addition to being featured on the Town's social media channels and in local newspapers.

Winning designs will remain on the assigned traffic signal box for a minimum of two years. Should damage occur to the box prior to that, the same design will be reinstalled. After two years, should the integrity of the wrap start to fade, damage to the box occur, or a new box be installed, a new design will be added to the box.

Congratulations to our 2023 design winners! To see winning designs from previous years, and to learn more about submitting your design to the Traffic Signal Box Art Project, please see below. For a map of all of the traffic signal box locations, click here.

The National Academies of Sciences, Engineering, and Medicine are private, nonprofit institutions that provide expert advice on some of the most pressing challenges facing the nation and world. Our work helps shape sound policies, inform public opinion, and advance the pursuit of science, engineering, and medicine.

Throughout any given year, the National Academies convene hundreds of conferences, workshops, symposia, forums, roundtables, and other gatherings that attract the finest minds in academia and the public and private sectors. These venues for discussion and debate are essential for allowing the scientific process to unfold.

The National Academies of Sciences, Engineering, and Medicine are the nation's pre-eminent source of high-quality, objective advice on science, engineering, and health matters. 

 Top experts participate in our projects, activities, and studies to examine and assemble evidence-based findings to address some of society's greatest challenges.

Our peer-reviewed reports present the evidence-based consensus of committees of experts. Published proceedings record the presentations and discussions that take place at hundreds of conferences, workshops, symposia, forums, roundtables, and other gatherings every year. And, our prestigious journals publish the latest scientific findings on a wide range of topics.

Discover what the National Academies are doing in various topic areas to strengthen the fields of science, engineering, and medicine and their capacity to contribute to the well-being of our nation and the world.

Few resources provide information related to selecting the most appropriate traffic signal phasing for the various geometric and operational situations encountered in the field. This is especially true for left-turn signal phasing decisions with respect to the level of control for the left-turn movement and whether left turns should precede or follow the main through movement.

The TRB National Cooperative Highway Research Program's NCHRP Web-Only Document 284: Decision-Making Guide for Traffic Signal Phasing is designed to give professionals designing or operating signalized intersections the tools they need to provide safe and efficient overall operations, considering both crash risk and movement delays.

The Chapter Skim search tool presents what we've algorithmically identified as the most significant single chunk of text within every page in the chapter. You may select key terms to highlight them within pages of each chapter.

A PDF is a digital representation of the print book, so while it can be loaded into most e-reader programs, it doesn't allow for resizable text or advanced, interactive functionality. The eBook is optimized for e-reader devices and apps, which means that it offers a much better digital reading experience than a PDF, including resizable text and interactive features (when available).

The City of Pittsburgh's Department of Mobility & Infrastructure (DOMI) is responsible for the maintenance and operation of 615 traffic signals and 92 flashing devices. DOMI is routinely replacing, upgrading, and assessing the need for traffic signalization on an ongoing basis. These improvement projects are funded through various sources, including the City of Pittsburgh Capital Budget, developer commitments and state-funded grants. This engage page is the hub for small-scale, city-wide traffic signal projects.

Descriptions of typical design features implemented through traffic signal upgrade projects are shown below. The actual list of individual improvements at each intersection are included under their respective pages.

Backplates on traffic signals improve visibility of the lights by placing them in a controlled-contrast background. Retroreflective borders added to the backplate improve visibility in both daytime and nighttime conditions. This addition is also beneficial during power outages when signals may otherwise be dark and less noticeable. 

Unlike traditional signals that employ "yield-on-green" indications, Flashing Yellow Arrow turn signals (FYA) feature a flashing yellow arrow in addition to standard solid red, yellow, and green indicators. FYA signals otherwise function identically to traditional signals. The implementation of the yellow arrow helps make intersections safer, as the arrow is more easily understood by drivers, and reduces delays when traffic is light. 

These installations are a standard pedestrian signal head with an added display showing a countdown of the remaining crossing time. This assists pedestrians and improves safety by sharing information about the amount of time left to safely cross the street before traffic signals change.

These are device installations that share information about the WALK and DON'T WALK phases at signalized intersections in non-visual manners for those who have impaired vision. These methods include audible instructions, vibrating buttons, etc.

The City of Pittsburgh, in certain instances, will use partial or full traffic responsive control systems. These systems depend on their ability to sense traffic for efficient traffic control. DOMI currently uses non-pavement invasive detection systems, using radar or video image detectors.

During design processes, DOMI assesses the need to add additional LED streetlights to traffic signal projects. The City currently uses a mixture of High-Pressure Sodium (HPS) and LED light installation. The difference, as shown in the picture above, between older HPS street lights (left) and updated LED light installations (right) is stark. Because they rely on older technology, HPS lights are less durable and energy efficient than LEDs. Additionally, the updated LED lighting provides increased visibility, improved safety for all users, and faster lighting repair/replacement times.
