Abstract:

This paper presents an overview of software called 'SAF' developed under FHWA sponsorship to assist in converting mainframe planning data sets into formats which can be input into microcomputer planning packages, and to focus large data sets for use in subarea planning with microcomputers. The software was tested using planning data for the Pensacola urban area. First the data, which was in UTPS format, was successfully converted with the aid of the software to formats for input into the microcomputer planning packages QRSII and Tranplan. To test its focusing capability, the software was then used to focus the Pensacola planning data for site impact analysis and the Tranplan package was run with the focused data sets. A comparison of model output from focused runs with an initial run made with the full (unfocused) data set indicates that SAF is a technical tool which has high potential for streamlining the subarea planning process.
