Applying Vehicle Dynamics Analysis and Visualization to Roadway and Roadside Studies
This report describes the application of vehicle dynamic modeling and visualization to highway safety design within the Interactive Highway Safety Design Model (IHSDM). This concept is intended to allow highway engineers to test roadway designs by computer simulation of vehicle encounters with roadway geometry and to assess roadway alignment and visibility features using three-dimensional (3D) graphical visualization. The procedures are intended to allow running a vehicle through design alternatives, to provide metrics of the vehicle/roadway encounter. This report reviews the overall design concept, the role of the Vehicle Dynamics Module (VDM) in providing performance metrics for a highway design, and the implementation of visualization procedures for viewing vehicle/roadway encounters including roadway features. An existing VDM (VDANL: Vehicle Dynamics Analysis, Nonlinear) was upgraded for this application to permit on- and off-road operation, articulated vehicles, and a generalized roadway design description. A simple interface and driver model was developed for running vehicles over highway designs. Several key performance measures were also developed for assessing the design, and were incorporated into the interface output.
