Abstract

Abstract

The laws of flow rate and headway varied with location in outside lane were studied. The highway capacity model of on-ramp freeway junction was analyzed. The empirical flow rate model was set up using regression techniques and statistical methods. It is pointed out that the headway distribution of traffic in outside lane is variable Erlang distribution. The merging behavior of ramp vehicle was analyzed with gap acceptance theory. The empirical highway capacity model of freeway on-ramp junction was set up by analysis the gap acceptance process. The results indicate that calculation value and measurement value almost equal, this model is feasible.
