This research project explores and evaluates the effectiveness of different static late merge signing for use on arterials. The research team collected data through a laboratory and a field study. The laboratory study assessed the comprehension of the different sign alternatives and determined which sign series to evaluate in the field. The field study evaluated a single sign series at 12 different sites across 3 States to evaluate driver behavior in response to the signs.
