Freeway ramp merging phenomena in congested traffic using simulation combined with a driving simulator

Abstract

Freeway ramp merging was studied under congested traffic conditions using a driving simulator (DS). First, the results of extensive macroscopic and microscopic studies were used to establish a model for the behavior of merging drivers. Based on this behavioral model, the Freeway Merging Capacity Simulation Program (FMCSP) was developed to simulate the actual traffic conditions. This model evaluates the capacity of a merging section for a given geometric design and flow condition. Next, a DS was developed to be used in conjunction with the FMCSP. The DS and simulation were combined by replacing one vehicle in the FMCSP by the DS. A pilot study was then undertaken to test for deficiencies in t..
