Research And Development Services And Related Consultancy Services – Design Recommendations For Divided Torsion Areas On Wide Highway Cross-Sections. On Motorways With A High Volume Of Traffic In German Metropolitan Areas, Symptoms Of Overload Can Sometimes Be Observed, Which Manifest Themselves In Traffic Jams Or Stalled Traffic. In Order To Be Able To Safely Handle Such High Traffic Volumes With Sufficient Traffic Flow Quality, Wide Standard Cross-Sections With Up To Five Lanes In Each Direction Of Travel Are Often Necessary On The Relevant Motorways. As Part Of The Development Of Wide Motorway Cross-Sections, It Must Be Noted That The Existing Regulation Of The Guidelines For The Construction Of Motorways (Raa; Fgsv 2008) Can No Longer Be Meaningfully Applied To Split Twists With The Resulting Constant Length Of The Twisting Section. At The Same Time, The Minimum Ramping Inclination Min ∆S Specifies The Minimum Inclination At Which Controlled Water Drainage Still Occurs. Both Regulations Lead To Large Height Differences In The Edge Area Of The Cross-Section With Wide Cross-Sections (8- And 10-Strip Total Cross-Section) And With An Off-Center Position Of The Axis Of Rotation. These Height Differences Should Be Reduced As Much As Possible. As Part Of The Research Project, It Is To Be Examined How Torsion Areas Can Be Realized On Wide Motorway Cross-Sections, Taking Into Account Sufficient Drainage. Furthermore, Regulations Must Be Developed For Divided Torsion Areas Of Wide Motorway Cross-Sections And For Off-Center Axes Of Rotation, Which Enable The Large Height Differences In The Edge Area Of The Cross-Sections To Be Reduced While At The Same Time Ensuring The Necessary Water Drainage. Since Certain Height Differences Cannot Be Completely Avoided During Split Twists On Wide Highway Cross-Sections, The Effects On Driving Dynamics Must Be Examined. The Findings Obtained In This Way Must Then Be Processed In Such A Way That Text Suggestions For Updating The Guidelines For The Construction Of Motorways Can Be Derived.
