PROPOSING CRITERIA FOR EVALUATION AND SELECTION OF INTERSECTION TYPES ON FREEWAY IN VIETNAM

Abstract

Now, in national standards such as: high speed Highways - Design requirements (TCVN 5729-2012, TCVN 4054-2005, TCXDVN 104-2007, TCN273-01),...there are no specific guide to the choice of interchange types on motorways in general and high-speed motorways in particular. We do not know what criteria to choose among a variety of technical, economic and exploitation indicators as the main criteria for choosing the type design, or to integrate those targets with each other so that we can have the most reasonable proposals and selections of design solutions to interchanges on high-speed motorway. This paper will present the research findings to suggest some key evaluation criteria and choose different kinds of intersections on high speed roads in Vietnam.
