Transoft Solutions is proud to be the first in the industry to be releasing the AASHTO 2011 National Standard Design Vehicle Library. We worked closely with the AASHTO Technical Committee contributing to the turning characteristics, kinematic model algorithms, and vehicle steering geometry of the standard design vehicles found in the new 2011 Green Book (A Policy on Geometric Design of Highways and Streets, 6th Edition, 2011).

The AASHTO Technical Committee on Geometric Design Chair, Mark A. Marek, PE, said, "We very much appreciate the technical assistance provided by Transoft Solutions and the willingness of your staff to share their knowledge of vehicular movement characteristics. The American Association of State Highway and Transportation Officials (AASHTO) Technical Committee on Geometric Design wishes to express our appreciation for the technical assistance provided by your company"

The AASHTO 2011 standard design vehicle library has undergone several changes. Older type vehicles have been removed and new ones added. In addition, vehicle design characteristics and specifications have been revised with the latest values.
