The report summarizes the techniques, procedures, findings, conclusions and recommendations of the research contract titled 'Gap Acceptance and Traffic Interaction in the Freeway Merging Process.' The primary objective of this research was the development of detailed criteria on traffic stream interaction for vehicles traversing a ramp and merging with the freeway traffic. The study included the following: the collection of data on traffic merging operations by aerial photography, at thirty-two entrance ramps located in eight of the major metropolitan areas in six states, data analysis through the use of computers, development of models describing mathematically gap acceptance characteristics, gap stability and lane changing characteristics in the vicinity of the merging area, the effects of acceleration lane length and angle of convergence in the merging operation, the application of this information to ramp design and merging control and the development of a computer simulation program for freeway merging operations. Based on the studies performed, the authors present thirty-one findings, conclusions and recommendations. (Author)
