Methods	CBA with Empirical Bayes analysis. Average before period of 6 years and average after period of 2.76 years
Participants	836 intersections across 7 jurisdictions around the USA (El Cahon, San Diego, San Francisco, CA; Howard County, Montgomery County and Baltimore, MD; and Charlotte, NC) with identified RLC problems in mid‐late 1990s
Interventions	132 RLC treatment sites (between 6 and 31 in each jurisdiction), 296 unsignalized non‐camera comparison sites (around 40–50 in each jurisdiction) similar to RLC sites and 408 signalized non‐camera reference sites (to calibrate safety performance functions and investigate spillover, 34–86 in each jurisdiction)
Outcomes	Total right angle crashes (right angle, broadside or turning crashes from perpendicular approaches), right angle definite injury crashes (exclude “possible” injury), rear end crashes, rear end definite injury crashes
Notes	Injury crashes include fatal and definite injury, exclude possible injury crashes
