QVIEW is a micro-computer based program developed to overcome the problems of difficult data entry, long running times and correct interpretation of results associated with mainframe based programs. Graphical techniques are used to help construct the tr model. Six main routines are used. These are as follows: (a) QUNET - network developments; (b) QJASN - link and junction-based assignments; (c) QJSEL - link/node cordon matrix extraction and assignments; (d) QVCOM - network assignment or comparisons; (e) QCORDON - interactive count data and interface with the CORDON su of programs; (f) QJAG which displays the JAM suite results at junctions. Details are given of the operation and capabilities o each routine and some typical output displays are illustrated. Distances, speeds or times can be entered as simple lines of text Nodes can be positioned using a cursor or by co-ordinates. Data can also be entered by a previously prepared file. Any link attribute can be displayed; speeds can be shown in bandwidth form required. A time, distance or generalised cost tree can be built from any node or zone and displayed at any stage of network editing or construction. Matrices can be created for selected li nodes or a cordon around a sub-area. More than one link or node can be selected.
