Abstract: TrafficNoiseCAD represents a new approach to noise analysis and barrier design by integrating file creation for the FHWA STAMINA 2.0 noise prediction program with interactive graphical techniques. The system consists of a series of routines that are a fully functioning part of AutoCAD running on an IBM-compatible microcomputer. Data conversion programs allow translation of AutoCAD drawing files into STAMINA 2.0 input files and vice-versa. During a digitizing session, TrafficNoiseCAD dynamically displays the drawing on screen as it develops. Changes may be made graphically on the screen through special editing commands. Also, dialogue boxes allow input of non-geographic information. Other AutoCAD functions can also be used at any step, such as isometric and true perspective views. Also, the user may split the screen into several windows, which is especially useful for noise barrier design.
