Abstract:
Merging locations are major sources of freeway bottlenecks and are therefore important for freeway operations analysis. Microscopic simulation tools have been successfully used to analyze merging bottlenecks and to design optimum geometric configurations and control strategies for such locations. In congested situations, acceptable gaps for merging are often not available and freeway mainline drivers often cooperate with the on-ramp drivers and create gaps for the merge. This is usually done either by decelerating or by changing to an inner freeway lane. Also, in some cases the merging driver may become impatient and decide to force in, which compels the lag driver in the freeway to decelerate. The lane-changing and acceleration decisions of the freeway mainline driver are therefore not only based on his present situation, but also influenced by the anticipated intention of the merging driver (e.g. whether or not the merging driver is executing a forced merge). Consequently, the merging models developed for a particular freeway may not be applicable to other freeways.
The major objective of this study is to develop empirical methodologies for modeling ramp driver acceleration-deceleration and gap acceptance behavior...
The knowledge of drivers on who has the right-of-way between the one on mainline lanes of a freeway and the one entering the freeway through on-ramp j...
