|
The first version of KHCM was published is 1992 and is currently used in engineering practice extensively. The study of new manual was initiated by Korea Institute of Construction Technology in 1998 and is intended to be ready for publication by the year 2002. According to the field survey, the action of the individual merging vehicle creates turbulence in the vicinity of the ramp-freeway junction area. The purpose of this paper is to develop the model for predicting the flow entering the lanes 1 and 2(V₁₂) and the density function at the influence zone by comparing the research works on the ramp junction in the USHCM 2000. The methodology has two major steps:the determinations of the flow entering Lanes 1 and 2 immediately upstream of the merge influence area; and the density of the flow within the ramp influence area. As a result of this paper the specific functions for such models are suggested through the regression analysis of data collected at four freeway fields in Korea. |
