• Abstract:
  Current Federal Highway Administration (FHWA) models were reviewed and the key mathematical formulations important to roadside hardware were defined. The review included identification of the important handling models as well as finite element based formulations. An outline for a single common user interface that organizes and automates data communications between and among the modeling capabilities was prepared. A survey of the vendors of nonlinear finite element analysis (FEA) codes was conducted as well as the collection of data defining computational requirements for the types of problems the FHWA would be considering in the design process. These data formed the basis for a recommended nonlinear FEA code. This study concluded that the public domain version of the DYNNNIKE suite of codes was preferred. A prototypical single common user interface was constructed and demonstrated. This demonstration software contained example programs of various kinds to illustrate functionality and key simulation technologies that st:10uld be developed in addition to nonlinear FEA. In particular, a prototype interactive vehicle dynamics model (IVM) was demonstrated. The interactive vehicle model demonstration was used to illustrate a "drive-through" capability for evaluating roadway design created on computer aided roadway design systems.
