About this file
The Pittsburgh Preliminary Streetlight Equity Analysis is a document prepared by the City of Pittsburgh's Departments of Mobility & Infrastructure (DOMI) and Innovation & Performance (I&P), detailing a comprehensive survey of streetlight coverage across city neighborhoods. In 2020 and early 2021, the city contracted with Cyclomedia to conduct a full photographic survey of utility poles and streetlights, creating the first complete geographic database of Pittsburgh's streetlights. The analysis was conducted in preparation for an RFP for citywide LED streetlight upgrades, with the goal of assessing streetlight equity and determining potential lighting improvements.
The study methodology established a target streetlight spacing of 150 feet on local roads, defining an area as "lit" if within 75 feet of a streetlight. Key findings reveal that neighborhood streetlight coverage ranges from 70% to 97%, with a median of 85% lit. The analysis estimates approximately 15,000 new lights and 8,500 new utility poles would be needed to achieve complete 150-foot spacing across all streets. To bring below-average neighborhoods up to the median lighting percentage, an estimated 2,900 lights and 1,600 poles would be required. The document includes a detailed map visualizing streetlight coverage by neighborhood, color-coded to show varying percentages of lit areas.

Pittsburgh Preliminary Streetlight Equity Analysis
Summary
Anecdotal reports indicate that many neighborhoods are perceived to suffer from a lack of adequate street lighting, leading to concerns about public safety. Prior to 2021, City of Pittsburgh did not have a comprehensive geographic database of its streetlights and could not evaluate these perceptions city-wide. Throughout the second half of 2020 and early 2021, Pittsburgh’s Departments of Mobility & Infrastructure (DOMI) and Innovation & Performance (I&P) contracted with the company Cyclomedia to conduct a full photographic survey of the city’s utility poles and streetlights, leading to the first ever full geographic database of Pittsburgh’s streetlights. Prior to issuing an RFP for the upgrade of city streetlights to LED (released in May, 2021), the City used this new database to roughly estimate how many new lights might be needed to address equity concerns related to the availability of streetlighting in city neighborhoods. This analysis was intended to provide a ballpark estimate of how much new lighting should be requested in the RFP – further analysis (including public engagement) will be needed before actual decisions about the number and placement of new lights is made.
Methodology
• Average streetlight spacing on local roads was identified as 150 feet, and this was selected as the target spacing for the purposes of analysis.
• Based on target spacing of 150 feet, any point within 75 feet of a streetlight was deemed “lit” and any point farther than 75 feet from a streetlight was deemed “unlit”.
Results
• Estimated number of new lights and new utility poles needed to bring all streets to 150 foot target spacing (many streets have existing utility poles without streetlights attached, so not all new lights require a new utility pole): approximately 15,000 lights and 8,500 poles needed.
• Percentage of street area “lit” and “unlit” by neighborhood, and average percentage “lit” across all neighborhoods: neighborhood “lit” percentage ranged approximately from 70% to 97%, and the median neighborhood was 85%.
• Estimated number of new lights and new utility poles needed to bring below-average neighborhoods up to average percentage “lit”: approximately 2,900 lights and 1,600 poles needed.
