Abstract

The development of a microscopic digital computer simulation model representing vehicle interaction at a weaving area under non-freeway condition is presented. Weaving areas are classified into two categories: 1. Weaving caused by merging and diverging of a ramp with an arterial, 2. On/off ramps connecting an arterial with a highway. The principal characteristics of the simulation model are the following: 1) a car following and lane changing model were used to represent vehicle movements; 2) an anti-collision check algorithm was developed for all vehicle movements; 3) driver merging urgency and follower courtesy model were developed for weaving vehicles. The simulation model was validated through field observation using video taping and photogrammetry techniques Comparative analyses between field observations and model predictions are carried out for non-weaving and weaving speed, as well as non-weaving and weaving acceleration. The results indicate that there is no statistically significant difference between the field data and simulation output.
