A GUIDE TO TRANSYT 7
TRANSYT/7 is a new version of a computer program which calculates optimum fixed time settings for traffic signals in a network. It is much faster than previous versions for large networks. The computer time required is now proportional to the number of links in the network rather than the square of the number of links. Evidence for this was obtained from ten networks of differing size and character. Data input to the program has been simplified and the changes are detailed in an appendix. Links can be listed in any order and closed loops of links are identified by the program and modelled by an iterative method to ensure that accurate values of the delay and queue length are obtained for all links in the loop. The modelling of bottlenecks has been included in TRANSYT/7. (Author/TRRL)
