Abstract

The article describes a study of traffic-merging behavior at three interchanges, using time-lapse photography. Close agreement was found between the observed distribution of available gaps and that predicted by the Poisson and shifted exponential distributions. Detailed study of about 550 individual vehicle paths indicates full use of the standard direct taper acceleration lane lengths with a wide range of driver behavior between easily defined 'short' and 'long' merges.
