Philadelphia's deadliest arterial road cut speeding violations by roughly 91% and pedestrian crashes in half after cameras went live in 2020 — evidence solid enough that the state made the pilot permanent.

Roosevelt Boulevard, long Philadelphia's deadliest arterial, has run automated speed cameras since June 2020 under a Pennsylvania pilot law (Act 86 of 2018) letting the Philadelphia Parking Authority enforce speed limits by camera rather than officer. Speeding violations fell roughly 91-95% in the program's first 18 months even as traffic volumes grew, and a peer-reviewed 2024 evaluation in Transportation Research Record found fatal and serious-injury crashes down 21% and pedestrian-involved crashes down 50% on camera-covered sections compared with similar roads, with an estimated eight fewer traffic deaths in 2020-2021. Pennsylvania made the pilot permanent and let Philadelphia add five more corridors in December 2023.
📊 Impact
Speeding violations down ~91-95% (June 2020-Nov 2021) despite rising traffic volumes; fatal/serious-injury crashes down 21% and pedestrian-involved crashes down 50% on camera-covered sections versus comparable roads (peer-reviewed: Guerra et al., Transportation Research Record, 2024); an estimated 8 fewer traffic fatalities in 2020-2021.
🎓 Lesson
A narrowly scoped, single-corridor camera pilot with an academic evaluation designed in from the start built a stronger case for permanence and expansion than a citywide rollout without one would have.
