Acceleration for Tractor Trailer Lane change?

[MSI]

Q: Looking for research on both normal and peak lat accel for TT?

A: One of our many research projects for FHWA included tractor trailer lane change maneuvers.

• HVOSM Studies of Highway Centerline Crown, Contract DOT-FH-11-9575
  The final report Safety and Operational Considerations for design of Rural Highway Curves, DOT-FH-11-9575, PB-86139664/AS

I believe much of the information culled from that research was used in the AASHTA Green Book

• (And later there was a conference called 'Beyond the Green Book': National Conference on Future Improvements to and Supplemental Guidance for AASHTO Policy on Geometric Design of Highways and Streets; Transportation Research Board Circular "Beyond the GreenBook". You'll see links for that and other related publications on our Publications page

There is also another related topic on the McHenry forum:

• What is the approx time/distance to make a lane change?
  Which includes reference to a paper on Tractor Semitrailer Left Turns and Lane Changes
