N2 - This article examines participants' behavior at collision detection and avoidance during parallel approaches and tests how it is affected by additional information on traffic displays. Participant behavior is analyzed by looking for "apparent strategies," measured by characteristics of participants' actions that remain consistent across scenar-ios with strongly different dynamics. The participants' collision detection reactions are found to occur at aircraft lateral separations that are consistent across a variety of scenarios; likewise, collision avoidance maneuvers with a "turn-away" component are consistently chosen for all scenarios. Unfortunately, these apparent strategies do not have adequate performance. Although some statistically significant differences in measures of participant behavior were found between display conditions, they were not substantial enough to increase performance.
