The procedures and techniques used to predict environmental impacts of transportation projects have been enhanced significantly in recent years. One of the remaining parts of an environmental study that is time consuming and error prone, however, is the creation of the input data files, particularly data on coordinates such as those for highways, noise barriers, and receptors. To overcome this problem, the Vanderbilt University Transportation Research Group has developed an interactive computer digitizing system, DIGIT-1, designed to measure and record coordinate data for input to the FHWA STAMINA 2.0 highway noise prediction program. The system allows recording of coordinates from plans of any size and scale and produces a practically complete, formatted STAMINA input file. Use of the system at Vanderbilt has resulted in reduction by more than half of data-file creation time in addition to significantly improved accuracy. The interactive measurement and recording of coordinates through the use of the DIGIT-1 system is examined in detail as well as enhancements for other environmental models.
