State departments of transportation often encounter public resistance to alternative intersections, with 86% of respondents in a new survey of state DOTs agreeing or strongly agreeing that public resistance hinders their implementation. Public resistance can vary among projects based on intersection type and whether the project was initiated at the local or state level.

The TRB National Cooperative Highway Research Program's NCHRP Synthesis 550: Alternative Intersection Design and Selection documents the evaluation and selection processes within state departments of transportation (DOTs) for intersection projects.

Roundabouts are the most widely implemented type of alternative intersection. Ninety percent of state DOTs that responded to the synthesis survey reported having at least one roundabout in their jurisdiction open and operational. Roundabouts also had the highest reported number of facilities in project development as 88% of respondents indicated there was at least one roundabout under development at their DOT.
