This research is expanding on a current study by collecting observations of all undesirable driving maneuvers on the remaining 2x2 roundabouts (two entering through-lanes crossing two exiting through-lanes) in Minnesota and relating the frequency of each individual type to specific design features. Although the resources this proposal is requesting will not allow for more than three roundabouts to be covered, it could be the impetus for a bigger pooled-fund study covering 15 to 20 roundabouts in several states.
