Abstract: In 1984 the California Department of Transportation (Caltrans) implemented a Computer-Aided Design and Drafting (CADD) pilot project to evaluate CADD for performing roadway design functions. Based on the favorable results of the pilot project, Caltrans is now in the process of implementing CADD on a departmentwide basis. This large CADD/interactive roadway design implementation project has developed considerable interest among the vendors, including several microcomputer vendors. Thus, in the near future, Caltrans anticipates that interactive roadway design capabilities will be supported by microcomputers and the microcomputer will become the workstation for the roadway design engineer.
