TRANSYT 6/N AND ITS USE AS A NETWORK EVALUATION TOOL

TRANSYT Version 6N is a modified version of the TRRL program TRANSYT/6. Modifications have been introduced primarily to enhance TRANSYT as a tool for the performance evaluation of traffic signal networks. The new facilities are link groups, intersection statistics, network evaluation calculations, search for optimum cycle time, external link speeds, additional traffic statistics and output options. These help to reduce and simplify input data preparation and provide additional output facilities, thereby reducing manual labour previously involved in extracting detailed information on network performance, in particular when different flow types such as buses and pedestrians in addition to general vehicles are used. All the new facilities of TRANSYT/6N are optional. TRANSYT/6N may therefore by used exactly in the format of TRANSYT/6. The changes have only been made to the main program and the input/output subroutines of TRANSYT/6. /TRRL/
