The Intercity Transportation Effectiveness computer programs are composed of a Data Base System, System Executive, and the ITE Model programs. The Data Base programs are used to create, update, and print the data base. The System Executive is used to control the flow of 'in process' data between the various programs of the ITE Model and to save intermediate and final results. The model programs are structured in five modules, namely, Passenger Demand, Cargo Demand, Routes, Network Assignment, and Timetable Building. Saved results can be printed by means of a Report Generator Program. The system is programmed in Extended Fortran IV for execution on a CDC 6600 computer. This volume contains detailed descriptions of the programs contained in each module. These descriptions are composed of detailed writeups of the subprograms comprising each program. Each writeup contains an abstract, input data and format specification, logic flow, output descriptions, programming notes, and listing of program tables and variables, together with flow-charts. Operating system control cards and program tape organization are also discussed. (Author)
