Determination of Onramp Weaving Length for Resolving Merging Dilemma
It is physically known that onramp merging may turn out to be difficult if the onramp (weaving/merging) length is too short because a driver under certain driving circumstances may find that either merging ahead or merging behind a neighboring vehicle on the adjacent highway lane cannot be completed...

It is physically known that onramp merging may turn out to be difficult if the onramp (weaving/merging) length is too short because a driver under certain driving circumstances may find that either merging ahead or merging behind a neighboring vehicle on the adjacent highway lane cannot be completed. Various existing guidelines or design manuals provide no clear physical understanding and explanations to the design onramp weaving length but often based on evolved empirical experiences. By integrating human factors, vehicle dynamic characteristics, roadway surface condition, and the onramp weaving design into a single unified analytic framework, the onramp length required for a driver to merge into the highway traffic successfully is determined exactly with formulas and physical solutions to avoid the merging dilemma and enhance driving safety at highway interchanges. The design onramp weaving length is examined and evaluated with various foreseeable merging scenarios and physical examples.
