4 pieces made the cut:
https://www.ugpti.org/resources/reports/downloads/mpc18-351.pdf 2019 Marshall/Ferenchak/Janson study finding 22% drop in all KSI from increasing density of PBLs to 5k linear ft / sq mi

https://www.nyc.gov/html/dot/downloads/pdf/safety-treatment-evaluation-2005-2018.pdf I love this one. Lots of %s for crash reduction of different treatments, 16.2% lower ped KSI from basic BLs & 29.2% lower from PBLs.

https://www.cambridgema.gov/-/media/Files/CDD/Transportation/Projects/cambridgestreet/SpeedandCountDataCambridgeStreet.pdf 6-7 mph lower speeds after BL went in.

https://www.fhwa.dot.gov/publications/research/safety/21012/21012.pdf reduction in all crashes by 30%.
