| Methods | CBA with Empirical Bayes analysis of 3500 crashes over 7 years |
| Participants | 72 signalized intersections over 6 jurisdictions in Northern Virginia |
| Interventions | 28 RLC intersections and 44 control intersections, with an additional 15 spillover sites (within 0.6 miles of RLC intersection) |
| Outcomes | Total crashes, injury crashes, angle crashes, rear end crashes, RLR crashes (driver charged with RL violation), injury RLR crashes |
| Notes | Employed 4 difference analyses with only EB extracted (paired t test, analysis of variance, generalized linear modelling and Empirical Bayes) |
