ADAAS(Automated Data Access and Analysis System). Program Documentation Manual

摘要

ADAAS, the Automated Data Access and Analysis System, is a set of computer programs maintained by the Transportation Data Center (TDC) at the University of Michigan's Transportation Research Institute (UMTRI). The programs are written in FORTRAN 77, and are resident on the Transportation Data Center Computer operating under the Sun Microsystems Solaris UNIX operating system. ADAAS is not a statistical analysis package like SAS or SPSS for example although it does possess some rudimentary statistical capability. It is intended instead as a means of accessing the large collection of transportation-related data sets maintained by the Transportation Data Center; and as a tool for performing preliminary analysis tasks on selected data as an integrated part of the system.
