An Update of the Green Book Design Vehicles

The objective of this research is to develop design vehicle material for the 8th Edition of the Green Book that realistically represents the critical vehicles that influence geometric designs. The material should include: (1) Critical dimensions and specifications (or ranges thereof) for design vehicles that can be applied to the design of intersection right and left turn lanes, roundabout elements, and other roadway elements; (2) Guidance on using this dimensional information in design, including selection of design vehicle(s) for a project, determination of when to allow large vehicles to encroach upon other lanes, and discussion on balancing the needs of different modes (e.g., trucks and pedestrians); and (3) An appropriate number of turning path templates that reflect a reasonable range of variability among design vehicles and guidance on when and how they should be applied.
