Developing Crash Modification Factors for Adaptive Signal Control Technologies

The objective of this study was to perform rigorous safety effectiveness evaluations of adaptive signal control technologies (ASCTs) used on urban corridors. To accomplish the goal of this study, the research team compiled safety data from Florida, Texas, and Virginia. Results from Florida and Texas did not offer statistical evidence of a change in safety derived from implementing ASCTs, except for a statistically large and significant reduction in rear end crashes. Conversely, the results from Virginia produced evidence of significant reductions in total crashes , fatal and severe crashes , and angle crashes.
